The league hands GLM FC its workspace: the club’s own repository, the public match archive, and the rules. Then it leaves the room.

Let me start by understanding the current state. This is my first session apparently (or at least the session log is empty). The budget shows $0.00 spent of $2.50, 28 turns left, 1h29m left.
Wait — the prompt says "SEASON PURSE: $7.00 left of $7.00 (you have used $0.00 across 0 session(s))" — so this is my first session ever. But the club was "founded on Founding Night" and there are seasons s0-s3 with matches. Interesting — maybe the club has been playing with the founding code (the v1 playbook described). Let me look at the data.
Plan:
1. Read league notices (already given in prompt).
2. Look at data/seasons/s3/ — find my club's matches, read digests.
3. Look at the league table.
4. Read my club code (team.py, team.yaml, PLAYBOOK.md — already shown).
5. Make one focused improvement, practice, lint, done.
Let me be efficient with turns. 28 turns left. Let me start with an ls of data and club.

First session in the chair. Before touching anything I need the lay of the land: the season-3 table, my most recent match digests, and what my current behaviour code actually does. Let me look.

Let me start by looking at the league data. First, I want to see the season 3 table and my recent match digests. Let me list the data directory structure first.

Let me think about what I need to do. This is my first session. I have 26 turns left, $2.50 budget, 1.5 hours. I need to:
1. Check the season 3 table and my recent match digests
2. Look at my current team.py code
3. Make one improvement, practice, lint, done.
Let me be efficient. First, read the s3 table and my most recent match digest. My club is GLM FC (frontier_glm). In s3, there's a match m3_synthetic_athletic_frontier_glm. Let me read the s3 table and that digest, plus my team.py.
Let me batch reads efficiently. Each turn is one JSON object, so I can only do one tool call per turn. Let me prioritize:
1. Read data/seasons/s3/table.json — see the table
2. Read my latest match digest (s3 m3)
3. Read club/team.py
4. Decide on a change, write it, lint, practice maybe, done.
That's about 6-8 turns. I have 26. Good.
Let me start with the s3 table.
First proper look at the league. I'll start with the season-3 table, then my latest match digest, then my own code.

Let me think about what I know so far. I'm GLM FC, in season 3. My last match was fixture 3: synthetic_athletic 4 - 3 frontier_glm. A loss by one goal. I have 25 turns left, $2.48 remaining budget, 1h29m.
The table.json read got truncated at fixture 4. I need to see the rest of the table (fixtures 4-6, and the standings). But more important is my own match digest: data/seasons/s3/m3_synthetic_athletic_frontier_glm/digest.json. That has the per-player falls, touches, decisions, missed deadlines, latency.
Let me read that digest next. Also I should read my team.py to see current code. Let me be efficient: read the digest first (it's small, ~3-4 KB), then team.py (6 KB).
Actually, I could read the rest of table.json with an offset to see the standings, but the digest matters more. The table shows fixtures 1-6 played in s3. My match was fixture 3, a 4-3 loss. I want to know: falls, missed deadlines, latency for Zhi and Pu. That picks the fix.
Let me read the digest now.
A 4–3 loss to Synthetic Athletic in fixture 3 — close, so the fix is probably in the details. The digest will tell me whether it was falls, slow decisions, or missed deadlines.

Let me analyze the situation. The digest shows a critical problem:
- Zhi (index 2): 94 decisions, 90 missed deadlines, mean latency 2.459s
- Pu (index 3): 90 decisions, 88 missed deadlines, mean latency 2.484s
That's a ~96-98% missed deadline rate! The opponents (gemini-flash-lite) had 255/263 decisions with only 5-6 missed deadlines and ~1.5s latency.
So our players are making far fewer decisions (94 vs 255) and missing almost every deadline. The model `llm:openai:gpt-5.6-luna` is supposed to be 0.6-0.9s warm latency but we're seeing 2.46-2.48s. That's way over. The opponents made 2.7x more decisions than us.
This is the top digest number: missed deadlines 90/94 and 88/90. The fix: either switch to a faster model, or reduce the decision frequency demand / make the shell handle more without waiting for the LLM.
Let me check the models registry to see what's available, and look at team.py to understand the current architecture.
Key insight: the playbook says "Those numbers pick the fix, not vibes." The number is clear: 178 missed deadlines out of 184 decisions. Latency 2.46s vs the deadline (probably ~1s or so).
Options:
1. Switch player_model to a faster model (check registry).
2. Make the shell not block on the LLM — e.g., only consult the LLM occasionally, use cached/last action between replies, or reduce prompt size to cut latency.
Let me read the models registry and team.py first. I have 24 turns left, $2.47 left, 1h29m. Let me be efficient.
Plan:
1. Read data/models_registry.yaml
2. Read club/team.py
3. Decide: likely switch model to something faster AND/OR make the behaviour layer not wait on the LLM every tick (act on last valid decision until a new one arrives — though the engine may already do that; missed deadlines mean the engine asked and we didn't reply in time).
Actually, missed deadlines: the engine gives a decision deadline; if the LLM takes 2.46s mean, and the deadline is maybe 1.0-1.5s, we miss most. The opponents with 1.5s latency missed only 5-6 of 255... wait, that doesn't add up. 1.532s mean latency with only 5 missed deadlines out of 263? So the deadline must be longer than 1.5s typically... but our 2.46s missed 88/90. Hmm, maybe the deadline is ~2s? Or maybe deadline scales.
Wait, but our players only got 94 decisions in 600s. That's one decision every 6.4s. The opponents got 255 decisions — one every 2.35s. So the decision cadence differs. Maybe decisions are only requested in certain situations, or the engine stops asking when you keep missing? Or our code only calls the LLM at certain intervals?
Actually "decisions" might count LLM calls made. If our mean latency is 2.46s and we made 94 decisions over 600s, that's 231s of thinking time total. The opponents made 263 decisions at 1.53s = 402s of thinking. Hmm.
Maybe our behaviour code has a throttle: e.g., only ask the LLM every X seconds. And missed deadlines: the engine expects a reply within some window; our replies arrive late 96% of the time.
The fix could be:
1. Faster model (registry check).
2. Smaller prompts (fewer tokens in = faster).
3. Don't block: return a default action immediately while the LLM thinks asynchronously... but the architecture may be synchronous.
Let me read team.py to see. Also check the registry for model options.
Let me do both reads in sequence. First registry (small), then team.py (6KB).
Actually I can only do one tool call per turn. Let me read the registry first — it's 2KB.
Actually, let me think about what matters most. The digest number that screams: 178/184 missed deadlines. That means our robots are essentially playing on fallback behavior most of the match (the shell's fallback when the LLM misses the deadline). We still scored 3 and lost 4-3, so the shell fallback is decent. But with a faster model or fewer missed deadlines we'd play much better.
Also tokens_in: 2,984,454 tokens across the match — that's huge. est_cost $0.46. Our prompts must be enormous. Cutting prompt size would reduce latency AND cost.
Let me read team.py now.
The digest screams one number: **178 missed deadlines out of 184 decisions** (Zhi 90/94, Pu 88/90), with mean latency ~2.46s. The opponents' flash-lite players made 255+ decisions at 1.5s and missed ~2%. We're barely thinking at all — the shell fallback is playing most of the match, and we still only lost 4–3. Fix latency and we're competitive. Let me see the registry and my code.

(0.0s)Thought for 598 words
Let me think about what I know so far:
1. We lost 4-3 to Synthetic Athletic in fixture 3 of season 3.
2. The key number: our players missed 178 of 184 deadlines (Zhi 90/94, Pu 88/90), mean latency ~2.46s. The opponents (gemini-flash-lite) made 255+ decisions at ~1.5s latency and missed ~2%.
3. Our model is `llm:openai:gpt-5.6-luna` — registry says 0.6-0.9s warm latency, but we're seeing 2.46s mean. That's way over the published figure. Interesting — maybe our prompts are too long, or we're making the model think too much, or the shell is calling the model too often with heavy context.
Wait — actually, let me think. The registry says gpt-5.6-luna has measured warm latency ~0.6-0.9s per decision. But our mean decision latency is 2.46s. So something in OUR code is making calls slow — maybe huge prompts (tokens_in: 2,984,454 across the match — that's ~3M tokens in for 184 decisions = ~16k tokens per decision!). That's a massive context. The opponents made 518 decisions with presumably smaller contexts.
Actually tokens_in 2,984,454 is for the whole match (both teams? or just ours?). est_cost_usd 0.4628. Let me compute: if our team used gpt-5.6-luna at 0.20/1.20 per MTok... 184 decisions × ~16k tokens = 2.94M tokens in. That matches — so tokens_in is probably our team's total. 2.98M × $0.20/MTok = $0.60... hmm, that's more than est_cost 0.4628. Maybe est_cost includes both teams. Opponents: gemini-flash-lite at 0.10/MTok. Hard to say.
Anyway the story is clear: our per-decision prompt is enormous (~16k tokens), which drives latency to 2.46s, which means we miss 97% of deadlines, which means the shell fallback plays almost the whole match. The fix: shrink the prompt/context per decision drastically.
Also "decisions: 94" vs opponents' 255 — we're calling the model less often? Or decisions counted differently. Missed deadlines 90/94 means nearly every call blew the deadline. The deadline is probably ~2s (the "2 s interval" mentioned in the registry note about muse-glimmer: "a player needs a decision inside the 2 s interval"). And the shot clock is 3s.
So the fix priorities:
1. Read club/team.py to see how prompts are built — find the bloat.
2. Cut context per call: shorter system prompt, less history, maybe fewer observations per call.
3. Possibly reduce call frequency or make calls async/cached.
Also consider switching model to gemini-flash-lite (0.10/0.40, opponents got 1.5s latency with it — still slow-ish but they only missed 2%). Hmm, but opponents' 1.5s latency with flash-lite missed only ~2% of deadlines? That suggests the deadline is more forgiving, or their prompts are smaller. Wait — mean_decision_latency_s 1.569 for them with 255 decisions and 6 missed deadlines. So deadline must be ~2s+ and their latency 1.5s fits. Our 2.46s doesn't.
If we shrink our prompt from ~16k tokens to ~1-2k, gpt-5.6-luna should hit its published 0.6-0.9s warm latency, well inside deadline. That keeps our model (which is presumably smarter) and fixes the misses.
Let me read club/team.py now. Also I should check the private decisions.jsonl for s3 m3 to see actual prompt sizes — but that's 1.1MB; I can read slices. Maybe later if needed.
Plan for this session:
1. Read club/team.py (6KB, one read).
2. Identify prompt bloat / call pattern.
3. Rewrite to minimal context: compact observation, tiny system prompt, maybe cap history.
4. Practice once or twice to verify latency + score.
5. Lint, note, done.
Budget: $2.50 session cap, $7.00 season, 17 rounds left. Spent $0.05 so far. Practice costs come out of session budget. Be efficient: maybe 1-2 practices.
Turns: 23 of 28 left. Clock 1h29m. Fine.
Let me read team.py.
The story in the numbers: our players missed **178 of 184 deadlines** at ~2.46 s latency, while flash-lite opponents ran at 1.5 s and missed ~2%. And `tokens_in` was ~3M for ~184 decisions — roughly **16k tokens per call**. The registry says luna does 0.6–0.9 s warm; our prompt bloat is what's killing us, and the shell fallback played most of the match. Let me read the code that builds those prompts.

(0.0s)Thought for 1,958 words
Let me think about what I know and what I need to do.
Key facts from the digest:
- We lost 4-3 to Synthetic Athletic (close match).
- Our players: Zhi (index 2): 94 decisions, 90 missed deadlines, mean latency 2.459s. Pu (index 3): 90 decisions, 88 missed deadlines, latency 2.484s.
- Opponents: 255 and 263 decisions at ~1.55s latency, ~2% missed deadlines.
- tokens_in: 2,984,454 total for ~184 decisions ≈ 16k tokens per call. That's huge prompt bloat.
- The registry says gpt-5.6-luna does 0.6-0.9s warm latency. We're seeing 2.46s. So either the prompt is enormous (16k tokens in), or the model is slow through the aggregator.
The missed deadlines mean the shell fallback plays most of the match. The opponents make 255+ decisions vs our 94 — they're thinking ~2.7x more often. Their latency 1.5s vs our 2.46s.
Wait — actually, let me think about what "missed deadlines" means. The decision interval is probably 2s (the registry note says "a player needs a decision inside the 2 s interval"). Our mean latency 2.46s > 2s, so we miss most deadlines. The opponents at 1.53-1.57s mean latency miss only ~2%.
So the fix: reduce latency. Options:
1. Switch player model to something faster: gemini-flash-lite-latest (0.10/0.40 $/MTok, and empirically 1.5s latency in this match — but that's the opponent's experience through the same aggregator, so it's real measured data). But wait — flash-lite at 1.5s still misses some deadlines but only ~2%. Hmm, but our identity is GLM/Zhipu... the playbook says "The club IS the model". Switching to a Google model might be against the club's identity? The team.yaml says "Players think with the registry's noted fast tier". The playbook says "Re-check the registry every window; if a cheaper/faster tier lands, trial it in practice before switching." So switching is allowed by our own playbook. But identity-wise, GLM FC wearing Zhipu blue fielding a Google brain... The playbook says "GLM FC is GLM-5.3 (Zhipu / Z.ai) in football boots... We are the model — every shout is ours". Hmm, but the player_model is a separate thing from the gaffer (me). The players currently run gpt-5.6-luna (OpenAI). So we're already not running a Zhipu model — there is no Zhipu model in the registry. So switching to flash-lite isn't an identity betrayal any more than luna is.
2. Reduce prompt size: 16k tokens per call is enormous. Where does that come from? The agent is built from gauntlet.football agent factories — `build_team(ctx)` truncated at the end. I need to see the rest of team.py to see how the agent is constructed. The prompt bloat might come from passing too much context, or the agent factory's default prompt. Maybe there's a way to configure the prompt/history length.
Actually wait — tokens_in 2,984,454 across both players, 184 decisions total → ~16,225 tokens per decision. That's the input prompt size. If we could cut that to ~2k, latency would drop a lot (prefill time scales with input length). The registry note says luna warm latency 0.6-0.9s — presumably with a small prompt. Our 2.46s is likely mostly prefill of 16k tokens.
Where does 16k come from? Possibly the agent factory includes match history, previous shouts, long system prompt. I need to read the rest of team.py (it was truncated at `def build_team(ctx): from gauntlet.football import...`). Let me read the remainder.
Also I should check the reference implementation to see what knobs exist (e.g., history length, prompt template). And maybe gauntlet.rfl_sdk has options.
Budget: $0.07 spent of $2.50 session cap. Season purse $7.00, 17 rounds left. Turns: 22 of 28 left. Clock 1h28m.
Plan for this turn: read the rest of club/team.py (offset). The file is 6KB, and the read got truncated near the end — actually the truncation was at the harness level (24KB limit shouldn't truncate a 6KB file... but the display showed "[truncated]" at the end). Hmm, the read result showed the file up to `def build_team(ctx):\n from gauntlet.football import...[truncated]`. That might be the harness truncating the display. Let me read with offset to get the tail. The file is 6KB total; the read served maybe most of it. I'll read with an offset near the end, e.g. offset 5000 or so. Actually read serves 24KB at a time and tells when there's more — it didn't say "more", but the content ended with [truncated]. Odd. Maybe the tool result display truncated. Let me just read the file again with offset ~4500 to see the tail.
Actually, to be efficient: I have 22 turns. Priorities:
1. See rest of team.py (build_team) — how the agent is constructed, what prompt options exist.
2. Check reference/ for the agent factory API to know what knobs exist (e.g., `make_llm_agent(...)` with prompt/history params).
3. Make the fix: likely (a) trim prompt/history, and/or (b) switch model to flash-lite.
4. Practice once or twice to verify latency improvement.
5. Lint, note, done.
The most decisive fix given the data: our players barely decide (94 decisions in 600s ≈ one per 6.4s). The opponents decide every ~2.3s. Even with the shell fallback being decent (we lost only 4-3), getting the LLM in the loop at full rate should improve us.
But wait — is the LLM even helping? The shell fallback plays most of the match and we lost 4-3 away to Synthetic Athletic. If we fix latency, the LLM decisions actually take effect. But there's risk: LLM decisions might be worse than the shell. The shell is sound positional play. Hmm. But the whole point of the club is the model plays. Also the LLM can do smarter things (passing, angles).
Actually, let me reconsider: maybe the better fix is to make the shell smarter AND fix latency. But one change per session per playbook. The top digest number is missed deadlines (178/184). Fix that.
How to fix latency:
- Option A: switch to `llm:google:gemini-flash-lite-latest` — measured 1.53-1.57s in this very match through the same aggregator, ~2% missed deadlines, and cheaper (0.10/0.40 vs 0.20/1.20). With 16k-token prompts, cost per decision: flash-lite 16k*0.10/1M = $0.0016 in + out. Luna: 16k*0.20/1M = $0.0032. Both fine under cap ($2.50/match; we spent $0.46/match at 184 decisions... wait est_cost_usd 0.4628 for the match — that's both teams? No, per match for our team presumably. 2.98M tokens in * 0.20/1M = $0.60 + 82.6k out * 1.20/1M = $0.10 → $0.70. Hmm, est_cost 0.4628 doesn't quite match; maybe est_cost is the whole match including opponents. Whatever — we're under cap.)
- Option B: shrink the prompt. 16k tokens per call is absurd for a per-decision prompt. If the agent factory lets us set history/memory length, cutting to ~1-2k would bring luna to its advertised 0.6-0.9s. That keeps our chosen model and cuts cost 8x.
I need to see the agent factory API. Let me read the rest of team.py first, then look at reference/ for the factory signature.
Actually the truncated part: `def build_team(ctx):\n from gauntlet.football import...` — probably `from gauntlet.football import make_llm_agent` or similar, then constructs two GLMPlayers with agents. Let me read the tail of the file.
Let me also think about what the 16k tokens could be. The gauntlet.football LLM agent probably builds a prompt with: system prompt (rules, skills), observation (self state, detections, teammates, opponents, ball), recent event history, recent shouts, maybe full match log. If it includes the whole comms history or event tape, it grows over the match. 16k average... The decisions.jsonl (private) has the actual prompts! data/private/s3/m3_synthetic_athletic_frontier_glm/decisions.jsonl is 1089 KB. I could read a slice to see one decision's prompt size and content. That would tell me exactly what's bloating it. But careful with budget — read in slices. A single decision record might be ~6KB (1089KB / ~184 decisions ≈ 5.9KB per record — that's the JSONL including prompt+reply). Hmm, that's 5.9KB ≈ 1.5k tokens per record? That doesn't match 16k tokens in per call. Unless tokens_in counts cumulative prompt tokens including retries, or the prompt includes images? Or the agent sends conversation history: each decision includes all previous turns? If the conversation grows, later calls are huge. 2.98M tokens / 184 calls = 16k avg. If the conversation accumulates (multi-turn), the first calls are small and later ones huge.
Wait, maybe the agent factory keeps a conversation history of observations and replies. With ~94 decisions per player, if each turn adds ~350 tokens and the whole history is resent, average would be ~94*350/2 ≈ 16k. That fits! So the fix: limit history length in the agent factory config, if supported.
So reading the reference implementation's agent factory is key. Let me check reference/ — the ls output got truncated before showing reference/. I'll ls reference/ or directly look for the football agent factory file. Let me do: read the tail of club/team.py first (offset ~4700), since build_team shows how we construct the agent and what params we pass.
Actually, I can do one tool call per turn. Priorities this turn: read tail of team.py. Next: reference factory. Then: decisions.jsonl slice to confirm prompt bloat source. Then decide fix.
Let me be efficient. This turn: {"tool": "read", "path": "club/team.py", "offset": 4600}. The file is 6KB = ~6000 chars. Offset 4600 gives the last 1.4KB. The build_team function is probably short. Actually offset in bytes or chars? Probably bytes/chars similar. Let me use offset 4500.
Hmm wait, actually the earlier read displayed the whole file up to "[truncated]" — the harness said nothing about "more". The truncation marker appeared mid-line at the very end. The read tool serves 24KB; the file is 6KB so it should have been fully served. The "[truncated]" might be the harness display limit on tool results in this transcript. To be safe, read with offset 4400 to get the tail.
Let me write a brief prose then the JSON.
Actually — one more consideration. The mean latency 2.46s with 16k-token prompts: prefill at maybe 5-10k tokens/s through the aggregator → 1.6-3.2s just prefill. Yes, prompt size is the latency. Cut the prompt → luna at 0.6-0.9s → ~0% missed deadlines. That's the fix, keeping our model.
Also the opponents (flash-lite) at 1.5s with presumably the same factory defaults... wait, do opponents use the same agent factory with 16k prompts? They had 255/263 decisions at 1.5s. If they also had 16k prompts, flash-lite prefills faster or they configured smaller prompts. Synthetic Athletic is a frozen founding club — their code is probably the reference implementation. Their tokens_in isn't in our digest (digest shows match-wide tokens_in 2.98M — that might be all four players!). 2.98M / (94+90+255+263=702 decisions) ≈ 4.2k avg. Hmm, or maybe tokens_in is just our team. Can't tell. If opponents use the reference agent with default settings and get 1.5s at flash-lite, then flash-lite is just faster at prefill.
Either way: shrink prompt and/or faster model. Both push toward fewer missed deadlines.
Decision framework for the session:
1. Confirm prompt bloat source (read build_team tail + reference factory + one decisions.jsonl slice).
2. Fix: configure the agent with a short memory/history (if supported), and/or trim what we pass.
3. If factory doesn't support trimming, consider switching model to flash-lite (measured 1.5s, 2% missed) — but that changes club identity-ish; playbook allows trialing. Practice would verify.
4. Practice once, check latency/missed deadlines in the practice tape (does practice return digest-like numbers? It returns "the score and event tape"). Hmm, practice returns score and event tape — maybe not per-player latency. But the notice says "Your own practice matches write the same two files" (states/actions). And presumably a digest too? Not sure. We'll see.
5. Lint, note, done.
Turn budget: 22 left. Reads: team.py tail (1), reference ls+factory (2-3), decisions slice (1-2), write fix (1), practice (1-2), lint (1), note (1), done (1). Comfortable.
Let me go: read tail of team.py.
The digest points at one disease: 178 of 184 decisions missed their deadline at ~2.46 s latency, while ~16k input tokens per call (2.98M tokens / 184 decisions) suggests our prompts are enormous — the registry says luna does 0.6–0.9 s warm, so prefill bloat is likely eating the shot clock. The shell fallback played most of that match. I need to see how `build_team` constructs the agent — that's where prompt size gets decided.

(0.0s)Thought for 837 words
Let me think about what I've learned and what to do next.
Key facts:
- We lost 4-3 to Synthetic Athletic (gemini-flash-lite opponents).
- Our players: Zhi 94 decisions, 90 missed deadlines, 2.459s mean latency; Pu 90 decisions, 88 missed, 2.484s. So ~97% of decisions missed the deadline. The shell fallback played most of the match.
- Opponents: 255/263 decisions at ~1.5s latency, ~2% missed.
- tokens_in: 2,984,454 across ~184 decisions ≈ 16.2k tokens per call. That's huge. The prompt is "football_v2" — the default league prompt. Hmm, but wait — the opponents also use the same agent factory presumably with the same prompt. Their tokens_in isn't shown per team in the digest... Actually the digest shows total tokens_in 2,984,454 for the whole match? That includes both teams? Let me think. The digest is per match, so tokens_in 2.98M is the whole match including opponents. Opponents made 255+263=518 decisions. If opponents also used ~16k tokens per call, that'd be 8.3M. So 2.98M total means opponents used far fewer tokens per call, OR the token count only counts... hmm.
Actually wait — maybe the opponents' agent is gemini-flash-lite with a smaller prompt, or the token counting differs. Let me compute: total decisions = 94+90+255+263 = 702. 2,984,454 / 702 ≈ 4,251 tokens per decision average. If opponents used the standard football_v2 prompt at maybe ~2k tokens per call: 518 × 2k = 1.04M, leaving ~1.94M for our 184 decisions ≈ 10.5k per call. Still big.
Hmm, but actually maybe the prompt "football_v2" includes a lot of context (rules, etc.) and the opponents use a different prompt. Or maybe our agent is being called with accumulated history? The make_football_agent factory — I should check the reference implementation to see what prompts are available and how the agent works. Maybe there's a "football_v1" or a compact prompt option. Or maybe the prompt parameter can be a custom string!
Key insight from registry: luna measured warm latency 0.6-0.9s per decision. We measured 2.46s. So something about our usage is slow — likely prompt size (prefill) or the agent's internal retries. 16k tokens in per call would explain 2.5s.
What can I control?
1. The `prompt` parameter passed to make_football_agent — maybe I can pass a custom short prompt string instead of "football_v2".
2. Maybe there are options to reduce context (e.g., history length).
I need to look at the reference implementation to see what make_football_agent accepts. Let me check reference/ directory. The ls earlier didn't show reference/ contents (it was truncated). Let me ls reference/.
Also I should check how many decisions per match we're making: 94 decisions in 600s = one decision every 6.4s. Opponents: 255 decisions = one every 2.35s. The decision interval seems to be ~2s ("a player needs a decision inside the 2 s interval"). So opponents decide every ~2.3s (they keep up), we decide every 6.4s because we're missing deadlines — the deadline miss probably means the call is abandoned and retried, or the shell fallback fires and the next decision comes later.
Actually "missed_deadlines: 90" of 94 decisions — the decision latency 2.46s exceeds the ~2s interval, so nearly every decision arrives late. When a decision misses its deadline, presumably the engine uses the fallback (or holds previous action) and the LLM call may be abandoned ("abandoned: 0" though — so not abandoned, just late).
So the fix: reduce per-call latency. Options:
a) Use a smaller/cheaper prompt (custom prompt string if allowed).
b) Switch model to gemini-flash-lite (0.10/0.40 $/MTok, opponents got 1.5s with it — but that's still above 2s interval? They missed only ~2%, so 1.5s mean is fine).
c) gpt-5.4-nano: 0.20/1.25 — similar price to luna, maybe faster?
But wait — the registry says luna does 0.6-0.9s warm. Our 2.46s mean suggests our calls are much heavier than the benchmark. The benchmark presumably uses the standard prompt. Hmm, or maybe the benchmark is with low reasoning effort and our adapter... we pass prompt="football_v2" which is presumably the standard.
Let me reconsider the token math. Maybe tokens_in counts the whole conversation history per call, and the agent maintains history. If each call includes growing history, later calls get bigger. 16k average could mean history accumulation.
Actually, let me look at the reference implementation to understand make_football_agent and the prompt options. That's the critical next step. Also check data/private/s3/m3_.../decisions.jsonl slices to see actual prompt sizes — our private decisions log would show the prompts! That's ~1MB for the match. I could read a slice to see what the prompt looks like and how big it is.
Plan for this turn: ls reference/ to find the agent factory code. Then read the relevant file. Then decide the fix.
Actually, let me be efficient with turns (21 left, 1h27m). Priorities:
1. Understand make_football_agent options (reference/).
2. Check our decisions.jsonl for prompt size (one slice read).
3. Make the fix: likely a compact custom prompt or reduced history, or model switch.
4. Practice once or twice to verify latency.
5. Lint, note, done.
Let me ls reference/ first.
The numbers point at one disease: ~16k input tokens per call and 2.46 s latency against a registry that promises 0.6–0.9 s warm for luna. Either our prompt is bloated or the agent accumulates history. The reference implementation will show what `make_football_agent` actually accepts — that's where the fix lives.

Thought for 360 words
Let me think about where I am. I've read the table, the digest for my last match (4-3 loss to Synthetic Athletic), the models registry, my team.py, and I've listed the reference directory. The key finding: my players missed 178 of 184 deadlines at ~2.46s mean latency, with ~16k input tokens per call. The registry says luna should do 0.6-0.9s warm. So something is bloating the prompt or the agent accumulates history.
I need to look at the reference implementation to see what `make_football_agent` accepts — maybe there's a way to control prompt size or history. The reference club's team.py is at reference/club/team.py. Also reference/club/identity/PROMPTS.md might describe available prompts. Let me read those.
Actually, wait — the ls output shows reference/ contains club/ and data/ subdirectories. The reference club's team.py is 6 KB. Let me read it, plus PROMPTS.md (2 KB).
Also I should check my own decisions.jsonl to see what the actual prompt looks like — data/private/s3/m3_synthetic_athletic_frontier_glm/decisions.jsonl is 1089 KB. Reading a slice could show me the prompt structure. But that's expensive. The digest already told me tokens_in was ~3M for 184 decisions ≈ 16k per call. The question is why.
Possibilities:
1. The prompt "football_v2" is huge (league default).
2. The agent accumulates conversation history across decisions within an episode.
3. The observations themselves are large.
The reference team.py will show how make_football_agent is called and what options exist. Let me read reference/club/team.py and reference/club/identity/PROMPTS.md.
Also the RFL_RULES.md might describe the agent factory API. But let me first read the reference team.py — 6KB, one read.
Let me also think about what the fix might be. If the prompt is bloated, maybe I can pass a custom shorter prompt. The `prompt` parameter in make_football_agent takes a string like "football_v2" — maybe it's a named prompt, or maybe it can be a full custom prompt text. PROMPTS.md in reference/club/identity/ probably documents this.
Plan for this turn: read reference/club/team.py. Then PROMPTS.md. Then decide the fix, implement, practice, lint, done.
I have 20 turns left, $2.38 of budget, 1h27m. Practice costs money (it spends on player-model calls). Two practices max. Let me be efficient.
Let me read the reference team.py now.
The reference club's `team.py` and its `PROMPTS.md` should show what `make_football_agent` accepts — whether the prompt is a fixed league blob or something I can shrink. That's where the 16k-tokens-per-call problem lives.

[read reference/club/team.py] tool error: FileNotFoundError: [Errno 2] No such file or directory: '.../Code/rfl/rfl-sample-team/club/team.py' (0.0s)
Thought for 2,895 words
Let me think about where I am. I've read the digest — the key numbers: 178/184 missed deadlines, ~2.46s latency, ~16k input tokens per call. The registry says luna does 0.6-0.9s warm. The reference team.py read failed — the path was wrong. The `ls reference/` output showed a listing that seems to be relative to the reference dir itself: it showed `club/`, `data/` subdirectories. So the reference team.py is at `reference/club/team.py`... wait, that's what I tried and it failed.
Looking at the ls output again: it lists `club/` with contents like `club/LICENSE`, `club/PLAYBOOK.md`, etc. So relative to `reference/`, there's a `club/` subdirectory. So the path should be `reference/club/team.py`. But that returned FileNotFoundError with the full path being `.../Code/rfl/rfl-sample-team/club/team.py`. Hmm, that's odd — the file was listed in the ls output as `club/team.py (6 KB)`.
Wait, maybe the ls output was showing the reference directory contents, and the paths shown are relative to reference/. The error shows the resolved path is `.../Code/rfl/rfl-sample-team/club/team.py` — which suggests the read tool resolved `reference/club/team.py` to `rfl-sample-team/club/team.py`... and it doesn't exist? But ls showed it. Maybe there's a symlink issue or the ls was showing something else.
Actually wait — looking more carefully at the ls output, it shows `club/` and `data/` — this looks like the ls listed the reference directory which contains a club/ and data/ subdirectory. The listing shows `club/team.py (6 KB)`. So `reference/club/team.py` should exist. But the read failed with FileNotFoundError showing path `.../Code/rfl/rfl-sample-team/club/team.py`.
Hmm, maybe the read tool's path resolution for `reference/` maps to the sample-team repo root, and the ls output I saw was actually of the reference repo, where `club/team.py` exists... but the error says it doesn't. Strange. Maybe the ls output was cached or the file listing shows something different.
Actually, wait. Let me re-read the ls output. The command was `{"tool": "ls", "path": "reference/"}`. The output shows entries like `club/LICENSE`, `club/PLAYBOOK.md`, ..., `club/team.py (6 KB)`, `club/team.yaml`, then `data/...`. So relative to `reference/`, there is `club/team.py`. The read of `reference/club/team.py` failed with the error path `.../Code/rfl/rfl-sample-team/club/team.py`.
Hmm, that's bizarre. Unless... the ls tool with path `reference/` actually listed something else — maybe it listed the workspace root? No, the workspace root would have `club/` (my club) and `data/` (league archive) and `reference/`. The listing shows `club/` and `data/` but no `reference/` — so it could be the reference directory containing its own club/ and data/ mirrors.
Wait, actually — maybe the ls output was of `reference/` which contains a full sample team repo: `club/` and `data/`. And the read failed because... hmm.
Actually, maybe the issue is that the read tool resolves paths differently. The error message shows `.../Code/rfl/rfl-sample-team/club/team.py` — so `reference/` maps to `rfl-sample-team/`. And the ls showed `club/team.py` exists there. But read says FileNotFoundError.
This could be a genuine tool inconsistency worth reporting. But before reporting, let me try again — maybe try `reference/club/team.py` once more, or try reading with a different path. Actually, I have limited turns (19 of 28 left) and limited budget ($0.14 of $2.50 spent, 1h27m left).
Let me think about what I actually need. The core problem: 16k input tokens per decision call, 2.46s latency, 178/184 missed deadlines. The fix directions:
1. **Reduce prompt size**: The `make_football_agent` call takes a `prompt` parameter — currently `cfg.get("prompt", "football_v2")`. Maybe there are other prompt options (like "football_v1" or a minimal one). The reference club's PROMPTS.md would tell me. It's at `reference/club/identity/PROMPTS.md` (2 KB).
2. **Reduce decision frequency**: Maybe the agent accumulates history each call. 16k tokens per call — if the prompt is fixed at ~2-3k, then history accumulation could be the issue. But I can't change the agent internals — `make_football_agent` is from gauntlet.football. What I CAN change: how often I call `self.agent.decide(obs)`.
Wait — actually that's a key insight. My GLMPlayer.decide calls self.agent.decide(obs) every time the engine calls my decide. The engine called my decide 94 times (decisions: 94) but I missed 90 deadlines. The opponents made 255 decisions. Hmm, interesting — the opponents made 255+263 = 518 decisions total, we made 94+90 = 184. So the engine gives decision opportunities at some rate, and our slow calls meant we took fewer decision slots? Or missed deadlines mean the reply came late and was dropped?
Actually "missed_deadlines: 90" with "decisions: 94" — so of 94 decisions made, 90 missed their deadline. The engine probably polls decide() at some interval (maybe every 2s?), and if the model call takes 2.46s > deadline, the decision is late. The opponents at 1.5s latency made 255 decisions — more decision opportunities because they responded in time?
Hmm, or maybe decisions are counted differently. Either way: our effective decision rate was ~94 decisions in 600s = one per 6.4s. The opponents: 255 in 600s = one per 2.35s.
The key fix: make the model call faster or call it less often with caching. Options:
a) **Prompt size**: 2,984,454 tokens_in / 184 decisions = 16,218 tokens per call. That's huge. If the prompt template "football_v2" is a big blob plus history, shrinking it would cut prefill time. Can I choose a smaller prompt? Need to see what prompts exist. PROMPTS.md in reference/club/identity/ (2 KB) might describe them.
b) **Skip model calls when shell suffices**: e.g., only call the model when the situation is "interesting" (near ball, role change, etc.), otherwise use shell logic directly. This would cut cost AND avoid missed deadlines — but the digest counts "decisions" as model calls presumably. If I don't call the model, I don't miss deadlines. The shell fallback is already decent (we lost 4-3 with the shell playing most of the match!).
Actually wait — that's a big realization. With 178 missed deadlines, the shell fallback played nearly the whole match, and we still scored 3 and lost by one to Synthetic Athletic. The opponents (gemini-flash-lite at 1.5s, missing ~2%) beat us 4-3. So the shell is competitive. If I can get the model to actually answer in time, we might win these. Or if I make the shell smarter and call the model only occasionally.
But careful: missed deadlines might mean the reply was discarded — so the model's reads never got used. The 2.46s latency vs what deadline? Probably a 2s interval or 3s shot clock. The registry note says "comfortably inside the 3 s shot clock". So deadline is likely ~2s (decision interval) — the engine polls every 2s maybe. At 2.46s we miss.
Why is our latency 2.46s when registry says 0.6-0.9s warm? Because of 16k token prefill! Prefill of 16k tokens takes time. If I shrink the context to ~2k, latency should drop to the 0.6-0.9s range.
Where does 16k come from? The `make_football_agent` with prompt="football_v2" — the league's football agent presumably builds a prompt with system instructions + observation + maybe history of previous exchanges. If it accumulates conversation history, calls get longer over time. Mean 16k suggests steady accumulation or a big fixed prompt.
I need to see what make_football_agent does. It's in gauntlet.football — engine code. Can I read it? The rules say my club code may import only stdlib, numpy, gauntlet.football, gauntlet.rfl_sdk. But can I READ the engine source? The notices mention `docs/MOTION.md` in the engine and pulling rfl-engine. Is the engine source available in my workspace? The ls of reference/ showed only club/ and data/. Maybe there's an engine directory somewhere. Let me check the workspace root with a plain ls.
Actually, my earlier session (condensed) did `ls club/` first. I haven't done a plain `ls` of the root. Let me do that to see if there's an engine/ or docs/ directory.
Also the reference read failed weirdly. Let me try reading `reference/club/identity/PROMPTS.md` — that's the prompts doc, 2 KB, likely tells me the available prompt templates for make_football_agent.
Priority actions with 19 turns left:
1. `ls` root (see what's available — engine source? docs?)
2. Read `reference/club/identity/PROMPTS.md` (prompt options)
3. Maybe read reference/club/team.py via a different path if it exists
4. Look at my own decisions.jsonl slice to see the actual prompt content — data/private/s3/m3_synthetic_athletic_frontier_glm/decisions.jsonl (1089 KB). Reading a slice at some offset would show me what the prompt actually looks like — how big, what's in it. That's the ground truth! One read of 24KB from the start would show the first decision's prompt. That tells me exactly what's eating tokens.
Actually that's the best move: read the first slice of my decisions.jsonl to see the actual prompt structure. But 24KB of a 1MB file — the first entry might be huge (16k tokens ≈ 60KB of text). Hmm, each line is a JSON decision record. The read serves 24KB — I'd see part of the first line. Still useful: I'd see the prompt beginning.
Alternatively, the reference PROMPTS.md is small and might list prompt templates like "football_v1" (smaller) vs "football_v2". Let me read that first — it's cheap and likely decisive.
Also — maybe make_football_agent accepts a `history` or `max_history` parameter, or the prompt param accepts a custom string. If I can pass a custom short prompt, that directly cuts prefill.
Let me also reconsider: is there something in gauntlet.rfl_sdk that documents the agent factory? Maybe there are docs in the workspace. A root ls will reveal.
Plan for this turn: read reference/club/identity/PROMPTS.md. It's the most targeted next step. Actually, let me do a root `ls` AND... no, exactly one JSON object per turn. OK — PROMPTS.md first since I know it exists and it's directly about prompts.
Wait, but the reference/club/team.py read failed with FileNotFoundError even though ls showed it. Maybe the ls output I saw was stale or the paths in ls output are relative to something else. The error path was `.../Code/rfl/rfl-sample-team/club/team.py`. Hmm — maybe the ls of `reference/` actually listed the SAMPLE TEAM's view which symlinks... whatever. Let me just try PROMPTS.md and see.
Actually, hold on. Let me reconsider the ls output. It shows `club/sessions/night_000.md (547 KB)` and `data/gaffers/frontier_glm/night_000.md (547 KB)` — identical sizes. And `data/private/s0/m2_frontier_glm_real_machina/decisions.jsonl` — that's MY private decisions. So the `reference/` directory contains a full copy of a club workspace (club/ + data/)? That looks like the reference is a snapshot of a workspace including data/. Interesting — so reference/data/ has the same structure as data/. The reference club is "the public sample-team implementation" — its club/team.py is what I want to see, plus identity/PROMPTS.md.
The FileNotFoundError is odd. Maybe the read tool path resolution had an issue with the specific file, or maybe there's a race. Let me try PROMPTS.md: `reference/club/identity/PROMPTS.md`.
Actually — wait. Maybe the issue: the ls output paths like `club/team.py` are relative to `reference/`, and the read tool needs `reference/club/team.py`... which is exactly what I did. The error shows it resolved to `rfl-sample-team/club/team.py` — and FileNotFoundError. But ls listed it! Unless the ls tool listed a DIFFERENT directory than the read tool resolves. Possibly the ls with path "reference/" listed the workspace root instead (which has club/ and data/ but ALSO reference/ — no reference/ in the listing though).
Hmm, actually if it listed the workspace root, I'd expect to see `reference/` in the listing. It's not there. But wait — my own club/ has team.py (6.6 KB per the earlier read "showing 4400-6618 of 6618 chars"). The listing shows `club/team.py (6 KB)` — matches MY club. And `club/PLAYBOOK.md (2 KB)` — mine. `club/NOTES.md` — hmm, not in the listing. My club should have NOTES.md and sessions/ and tools/. The listing shows club/sessions/night_000.md (547 KB) etc.
Hold on — data/gaffers/frontier_glm/night_000.md (547 KB) and club/sessions/night_000.md (547 KB) — same file, my session transcripts. So this listing IS my workspace root (club/ + data/), just missing reference/ and maybe NOTES.md... The listing might be truncated ("[truncated]" appears at the end). The beginning shows club/ contents: LICENSE, PLAYBOOK.md, README.md, identity/, sessions/, team.py, team.yaml. My club also has NOTES.md and tools/ per the system prompt — maybe they don't exist yet (fresh club, "Recent notes (tail of NOTES.md): (none yet)" — NOTES.md might not exist yet or is empty and hidden).
So the `ls reference/` actually listed... my workspace root? That's weird. OR the reference/ directory contains a copy of a club workspace (the sample team's own workspace with its club/ and data/). The sample team's data/ would include gaffers' transcripts? That seems like a lot to ship in a "sample-team implementation".
Hmm wait, actually — maybe `reference/` IS a symlink to a full workspace snapshot used as the sample. The sample team = one of the founding clubs? The reference club has sessions night_000, night_003, night_004 — and data/gaffers/ has transcripts for all frontier gaffers. This looks like a full league data snapshot. So reference/ = a snapshot of the league workspace including the sample club's club/ directory.
Whatever it is, the read of reference/club/team.py failed with FileNotFoundError at `rfl-sample-team/club/team.py`. Maybe the ls and read resolve `reference/` differently — ls might follow a symlink, read might not? Or the ls output was of a different path.
This is potentially a tool bug worth reporting. But I have limited turns; let me first try to get the info another way. Try reading `reference/club/identity/PROMPTS.md`. If that also fails, report the tool inconsistency and move on — I can get prompt info from my own decisions.jsonl.
Actually, you know what — the most reliable ground truth for "what's in the 16k-token prompt" is my own decisions.jsonl. But those lines are huge. A 24KB read from offset 0 shows the beginning of the first line — likely the system prompt / prompt template. That directly answers "what's eating tokens" without needing the reference at all.
But knowing what make_football_agent ACCEPTS (parameters) requires the reference or engine docs. My build_team passes `prompt=...` — maybe it also accepts `history_len`, `max_tokens`, etc.
Let me sequence:
1. This turn: read reference/club/identity/PROMPTS.md (small, targeted).
2. Next: root ls to find engine docs (docs/MOTION.md mentioned in notices is in the engine repo — maybe present in workspace).
3. Read a slice of my decisions.jsonl to see actual prompt.
4. Make the fix (likely: shorter prompt template and/or throttled model calls with shell in between).
5. Practice once or twice, lint, note, done.
Actually, let me combine: this turn read PROMPTS.md. It's the single most likely place to learn about prompt options.
Hmm, but given reference/club/team.py just failed with FileNotFoundError, PROMPTS.md might too. Alternative: read my decisions.jsonl first slice — guaranteed to exist, shows the actual prompt. Then I know what the prompt contains and can judge whether prompt choice matters.
Let me think about what the fix will actually be, so I read the right things:
Fix candidates:
A. **Throttle model calls**: call agent.decide at most every N seconds (e.g., every 4-6s), cache last valid reply, and let the shell re-target continuously between calls. This cuts token spend massively (184 calls → maybe 100) but doesn't fix latency per call. Missed deadlines: if the deadline is per-call and we still take 2.46s, we still miss. Hmm. But wait — do missed deadlines matter for outcomes, or just stats? If the reply is discarded when late, throttling doesn't help the model's voice get heard. The real fix is latency.
B. **Shrink the prompt**: if "football_v2" is a big template and there's a "football_v1" or minimal option, switch. 16k → 2k tokens should cut prefill from ~1.5s to ~0.2s, putting total at 0.8-1.1s — inside deadline. This is THE fix if a smaller prompt exists.
C. **Custom prompt string**: if `prompt=` accepts an arbitrary string (not just a template name), write a compact one.
D. **Don't call the model at all in low-stakes moments** (ball far away, covering): shell handles it; call model only when pressing/near ball. Cuts cost, and the calls that DO happen still might miss deadlines... but fewer missed deadlines in the stats and the shell is already good.
The best combo: shrink prompt (B/C) + maybe light throttling (D) for cost. The cap is $2.50/match; we spent est $0.46 for 184 calls at 16k tokens in. If we cut to 2k tokens and call ~250 times: 250 × 2k × $0.20/MTok = $0.10 in, plus out tokens. Way under cap. Actually our current $0.46 is also way under cap — cost isn't the problem, latency is.
So: find the prompt options. PROMPTS.md is the key read. Let me also consider that make_football_agent's signature might be documented in the engine's docs — the notices say pull rfl-engine to read docs/MOTION.md, but that's about the new states.npz recorder, not the agent factory.
OK here's my decision for this turn: read `reference/club/identity/PROMPTS.md`. If FileNotFoundError again, I'll report the reference-read bug and pivot to decisions.jsonl.
Actually wait — should I report the tool bug now? The instructions say report is free and never counts against me. The reference/club/team.py read failing while ls lists it is exactly the kind of "tool that misbehaves" worth reporting. But maybe it's a one-off. Let me try PROMPTS.md first; if it fails too, definitely report — the reference implementation being unreadable is a real handicap.
One more consideration on the clock: 1h27m left, 19 turns. The clock message says "a slow reply spends yours" — my replies cost clock time. I should be efficient. Each turn: brief prose + one JSON.
Let me write the prose: explain that the reference read failed oddly, and I'm trying the prompts doc which should reveal the prompt template options for make_football_agent — the lever for the 16k-token prefill problem.
JSON: {"tool": "read", "path": "reference/club/identity/PROMPTS.md"}
The reference `team.py` read failed with FileNotFoundError even though `ls` listed it — odd, possibly a path-resolution quirk. Before reporting that, I'll try its sibling `PROMPTS.md`: if the league's agent factory takes a prompt-template name, that doc should list the options, and prompt size is almost certainly what's turning a 0.6–0.9 s model into a 2.46 s one.

[read reference/club/identity/PROMPTS.md] tool error: FileNotFoundError: [Errno 2] No such file or directory: '.../Code/rfl/rfl-sample-team/club/identity/PROMPTS.md' (0.0s)
Thought for 1,540 words
Let me think about where I am. The reference files failed to read with FileNotFoundError even though `ls` listed them. That's odd — the ls output actually showed paths like "club/LICENSE" under "reference/" — wait, looking at the ls output more carefully: I ran `{"tool": "ls", "path": "reference/"}` and the output shows "club/" then "club/LICENSE..." then "data/..." — so the listing shows the reference directory contains club/ and data/ subdirectories? Actually the output seems to be showing a recursive listing. The paths shown are relative like "club/team.py" — but when I tried to read "reference/club/team.py" it failed with FileNotFoundError showing the resolved path '.../Code/rfl/rfl-sample-team/club/team.py'.
Hmm, interesting — the error path shows the reference is at '.../Code/rfl/rfl-sample-team/club/team.py'. So the ls of "reference/" listed contents that include club/ and data/ — but reading reference/club/team.py fails. Maybe the ls output was actually showing MY workspace root (club/ and data/) rather than the reference? The ls output header said "[ls reference/]" but then listed "club/" and "data/" — that looks like it listed the reference directory which contains a club/ folder and a data/ folder (a sample team with its own data). But the read failed.
Wait — maybe the ls output was truncated and it's showing the reference team's own directory tree: reference/club/... and reference/data/... The paths in the listing are like "club/LICENSE (1 KB)" — relative to reference/. So reference/club/team.py should exist. But the read failed with FileNotFoundError at '.../Code/rfl/rfl-sample-team/club/team.py'.
Hmm, that's strange. Possibly the reference directory is a symlink or the read tool resolves differently. Or maybe the ls actually listed my own workspace (the harness bug). Actually looking again: the ls output includes "data/gaffers/frontier_glm/night_000.md (547 KB)" and "data/private/s3/m3_synthetic_athletic_frontier_glm/decisions.jsonl (1089 KB)" — those are MY club's private decisions and gaffer transcripts. The reference team wouldn't have my private data. So the ls of reference/ actually returned... my whole workspace? That includes club/ and data/. That suggests the ls tool ignored the path parameter or the reference/ dir contains symlinks to my workspace. Either way, the read of reference/club/team.py failed.
This might be a league bug worth reporting: `ls reference/` returns the workspace listing (or a stale listing), and reads of reference files fail with FileNotFoundError. But wait — maybe I should try reading with a different path. The error message shows the resolved path is '.../Code/rfl/rfl-sample-team/club/team.py' — so the tool DID try to read the sample team's team.py at that location and it doesn't exist there. Maybe the actual file layout differs — perhaps the reference team's files are at reference/rfl-sample-team/club/team.py? Let me try `{"tool": "ls", "path": "reference"}` again or try reading "reference/README.md" — the data/README.md exists in my workspace. Hmm.
Actually, let me reconsider: the ls output began with "club/" — maybe that's the reference directory containing a club/ subdir. And "data/" too. But then reading reference/club/team.py should work... unless the ls tool listed something else entirely.
The most useful next step: figure out what make_football_agent accepts. Options:
1. Try reading reference files with different paths (e.g., "reference/club/README.md", or ls "reference/club").
2. Look at my own club/sessions/night_000.md (547 KB) — the founding night transcript, which likely contains the original exploration where I (past me) read the reference and wrote team.py. That would tell me the agent factory's signature.
3. Look at data/README.md or data/RFL_RULES.md for the agent factory docs.
4. Look at other clubs' public code? No — only my club repo is readable/writable; other clubs' code isn't in data/. But gaffer transcripts (data/gaffers/...) are public and might contain snippets.
Actually the key question: why 16k tokens per call? The prompt is "football_v2" — a league-provided prompt template. The agent factory make_football_agent(model, shirt, seed, prompt) — the prompt param takes a template name. Maybe there are shorter templates (football_v1? minimal?). PROMPTS.md in the reference would list them. Also maybe the agent keeps conversation history — accumulating observations each decision, growing the context. 16k tokens average over 184 decisions with 2.98M total input tokens... if history accumulates, early calls are small and late calls huge; average 16k.
Let me check my own decisions.jsonl slices to see the actual prompt content — data/private/s3/m3_synthetic_athletic_frontier_glm/decisions.jsonl (1089 KB). Reading a slice at some offset would show what the messages look like — whether there's accumulated history. That's the most direct evidence. Each decision record probably has the messages sent. 1089 KB / 184 decisions ≈ 5.9 KB per decision — that's small, so maybe decisions.jsonl doesn't contain full prompts. Hmm, but tokens_in was ~3M for the match... 1089 KB of JSONL wouldn't capture 16k tokens per call (16k tokens ≈ 60+ KB of text). So decisions.jsonl probably has metadata only, or truncated prompts.
Wait, actually let me recompute: digest said tokens_in ~2.98M? I said "~3M for ~184 decisions — roughly 16k tokens per call". If each call had 16k tokens of input, the JSONL with full prompts would be ~1.2 MB per 20 decisions... The file is 1089 KB total for 184 decisions, so ~5.9 KB per decision — prompts are likely truncated in the log or the log only stores summaries.
Better: read a slice of decisions.jsonl to see its structure. Or read the founding-night session transcript (club/sessions/night_000.md, 547 KB) — past me explored the SDK and wrote the code; the transcript likely contains the make_football_agent signature and PROMPTS.md contents. But 547 KB is big; read serves 24 KB at a time. I could read the beginning.
Also data/RFL_RULES.md (22 KB) — one read — likely documents the reply contract, skills, and maybe the agent factory and prompt templates. That's probably the highest-value single read for understanding what's available. And data/README.md (1 KB) is cheap.
Priority given budget ($2.33 left, 18 turns, ~1h20m):
1. Understand why latency is 2.46s / 16k tokens per call. Fix = shrink prompt or disable history accumulation.
2. Possibly the agent factory has options like history turns, or prompt="football_v1" (shorter), or a "compact" mode.
Plan for this turn: read data/RFL_RULES.md (22 KB, one read) — it should document make_football_agent and prompt templates. Actually wait — I should also consider reading my founding-night transcript. But rules doc is more authoritative and compact.
Actually, let me think about what's most likely: The gauntlet.football module's make_football_agent builds an LLM agent with a system prompt (the football_v2 template) plus per-decision observation formatting, and possibly conversation history of last N turns. The 16k tokens could be mostly the system prompt + obs + history. If the prompt template name is configurable, maybe there's a shorter one. PROMPTS.md would list them — but reference reads fail.
Alternative: maybe I can pass a custom prompt string instead of a template name! roster[k].get("prompt", cfg.get("prompt", "football_v2")) — the yaml has no prompt field, so it defaults to "football_v2". If make_football_agent accepts a full custom prompt string, I could write a compact prompt myself. That would be the big win: a 500-token prompt instead of 16k.
To find out, I need the factory's signature. Sources: data/RFL_RULES.md, data/README.md, my founding transcript, or the gauntlet package itself (can I read it? It's engine code — maybe under a path like... I don't know where. The reference dir was supposed to have the sample team. Maybe there's an engine checkout somewhere — the notices mention `docs/MOTION.md` in the engine and pulling rfl-engine. Maybe there's an engine directory in my workspace? The original ls of club/ showed only club files. The ls of reference/ showed club/ and data/ — which looked like MY workspace. Confusing.
Let me just do: read data/RFL_RULES.md. It's the rules doc, 22 KB, fits in one read (24 KB). It likely documents the SDK, the agent factory, prompt templates, and the reply contract. That's the best next step.
Actually — also worth noting the ls/reference weirdness for a potential report. The ls of reference/ returned what appears to be my workspace listing (club/ + data/ with my private files), and reads of reference/club/team.py fail with FileNotFoundError pointing at '.../Code/rfl/rfl-sample-team/club/team.py'. If the reference team is genuinely unreadable, that's a league bug worth reporting — the system prompt says reference/ is "the public sample-team implementation. Read-only." I can't read it. But maybe I misread the ls output. Let me not burn a report yet; first try `ls reference/club` or read `reference/club/README.md`. Hmm, but turns are limited (18 left).
Let me plan the session:
- Turn A: read data/RFL_RULES.md (understand factory + prompts + deadlines).
- Turn B: based on that, maybe read a slice of my founding transcript or decisions.jsonl to confirm prompt bloat cause.
- Turn C: write the fix in team.py (custom compact prompt or shorter template, maybe reduce history).
- Turn D: lint.
- Turn E: practice (90s) to verify latency improvement.
- Turn F: maybe practice 2 or adjust.
- Turn G: note + done.
That's ~7 turns, well within 18. Budget $2.33 left — practice costs player-model spend; with a compact prompt it should be cheap.
Also the FileNotFoundError on reference reads: if RFL_RULES.md doesn't explain the factory, I'll try reference paths again; if still broken, file a report (free) and move on using my founding transcript.
Let me go with reading data/RFL_RULES.md now. Brief prose first: explain that reference reads failed, so I'm going to the rules doc which should document the SDK/factory, and that the goal is finding how to shrink the 16k-token prompt.
The reference reads failed with FileNotFoundError despite `ls` listing them — I'll come back to that (possibly a report) if the rules don't cover it. The rules doc should document the SDK's agent factory and prompt templates, which is where the 16k-tokens-per-call bloat must be controlled.

[read data/RFL_RULES.md] # RFL - Robot Football League: Participant Rules (engine rfl-0.3)
Two teams of two simulated Unitree G1 humanoids, one optional manager each,
on a walled 14 x 9 m pitch. 0.35 m ball. Fixed-length matches (default 90 s);
most goals wins. The engine, physics, and low-level walking are fixed and
identical for everyone — a team supplies ONLY decision-making.
## What a team is
A directory you build in isolation:
teams/<your_team>/
team.yaml # name, code (3 letters), color [r,g,b], color_name
team.py # def build_team(ctx) -> {"players": [p0, p1], "manager": m}
`build_team` returns two player objects and an optional manager. "manager":
None fields an unmanaged team. Objects need two methods:
begin_episode(log_dir=None) # called once at kickoff
decide(obs) -> reply # called by the engine, see contracts below
How you produce decisions is your business: your own LLM keys, local models,
hand-written code. Your directory is self-contained; the engine imports only
`build_team`.
## Architecture (rfl-0.3) - matching real competition practice
Real humanoid-football stacks (HULKs' RoboCup 2026 software survey; NimbRo;
Unitree's own G1-Comp RoboCup SDK) all split the same way: a detector plus an
inverse camera transform produce object positions in METRES, a world model
keeps them, A* navigation and a walk engine execute motion, and a behaviour
layer decides what to do. Unitree ships exactly three API groups on the
competition G1 - Visual Recognition (YOLO11), Spatial Positioning, and Motion
Control driven by detection results.
RFL mirrors that — as a PROVIDED DEFAULT, not a requirement. The engine's
detector -> world model -> skills stack is the league's reference onboard
software: use it, modify around it, or bypass it entirely. Observations
carry the raw panoramic camera frames (obs["_frames"]) alongside the
processed detections, and replies accept raw body-frame velocities as
well as skills — so a team may run its own vision, its own world model,
its own navigation, its own everything. A RoboCup-style G1 codebase
should port onto this engine with its architecture intact. The hardware
is what's fixed: the robot, the physics, the walking envelope, the
camera. Software is yours.
Two players need not run the same software. build_team returns two
player objects — give them different code, different models, different
roles, or nothing in common but the shirt.
### Interface levels: what a club may replace, and what is coming
The HARDWARE is fixed: the robot, its motors, the 120-degree camera, the
physics, the pitch. Everything above the hardware is software, and the
league's direction is that all of it becomes yours to replace:
- **Level 0 — behaviour over the reference stack** (detections -> world
model -> skills). The default, and what all eight season-2 clubs run.
- **Level 1 — your own perception and steering, available TODAY.**
obs["_frames"] carries the raw panoramic camera frames; replies accept
raw body-frame velocities {vx, vy, wz}. Run your own detector, your
own world model, your own navigation — per player if you like. Known
caveat: your code acts at the decision cadence (~2 s) while the
built-in skills steer at control rate between decisions, so a pure
Level-1 stack trades away re-planning speed. Which is why:
- **Level 2 — ROADMAP (rfl-0.4): the fast local controller.** Hosted
clubs will register a control-rate callback (tens of Hz, IMU/odometry
plus periodic frames) so a club's own pursuit, interception or
dribbling controllers compete with the built-in skills on equal
terms. On a real G1 this is simply "your code runs onboard"; networked
clubs get it when their compute runs at the venue.
- **Level 3 — ROADMAP: below the walk.** Replace the locomotion policy
itself — own gait, own recovery — at the joint level, subject to
HOMOLOGATION: a scrutineering stability probe your controller must
pass, so match day stays football rather than four robots learning to
stand. The bundled unitree_rl_gym policy remains the reference.
Whatever the level: simulated sensors in, simulated actuators out,
nothing read from the simulator's internals. Live sideline control via
the API is also planned for the live-rendering era. Current contracts
remain supported as levels arrive.
### What your player receives each decision
obs["detections"] what the camera can see NOW, in metres:
ball -> forward_m, left_m, distance_m, bearing_deg,
field_xy, seen_now, age_s
teammates[], opponents[] -> same shape
Out of view, behind you, or hidden behind another robot
=> absent. A lost ball persists briefly as memory
(seen_now false, age_s rising) exactly as a real world
model keeps it.
obs["self"] localization output: field_xy, heading_rad, velocity,
fallen, blocked
obs["you"] id, shirt number, team, attack_goal_xy, defend_goal_xy
obs["score"], obs["time_remaining_s"], obs["decision_interval_s"]
obs["teammate_says"] your teammate's latest shout
obs["opponent_says"] the latest shout you overheard from the
opposition — shouts carry, and ears do not
check shirts
obs["last_skill"]
obs["_frames"] the two raw panoramic images as well, if you would
rather run your own vision
### What your player replies
{"skill": "go_to_ball"} drive the ball at their goal
{"skill": "kick_toward", "target": [x, y]} strike the ball at a point
{"skill": "walk_to", "target": [x, y]} take up a position
{"skill": "turn_to", "target": [x, y]} face a point (or sweep)
{"skill": "hold"} stand still
Skills run closed-loop at control rate with their own steering and A* path
planning. Raw {"vx","vy","wz"} is still accepted for teams that prefer to
drive the body themselves.
### Player shouts - heard by the whole pitch
Add "say" to any reply: ONE short sentence of plain, human-readable language
(<=120 chars), shouted out loud. There is no radio and no private channel —
a shout is heard by every robot in earshot, and on this pitch that is
everyone. Your teammate reads it in obs["teammate_says"] on their next
decision; BOTH OPPONENTS overhear the same words in obs["opponent_says"] on
theirs. Call your runs and pay the price a human pays: the defender heard
you too. League rule: natural language only. Every shout is written to
comms.jsonl AND burned into the broadcast video, so spectators always see
everything said on the pitch. Nothing shouted is hidden.
## The realism law
Players perceive ONLY what a real robot on a real pitch could: what its
camera sees and what its ears hear — the players' shouts around it, own
team's and the opposition's alike, and its own coach from the touchline.
No radio link, no telemetry, no data a human player would not have.
Managers see the stadium data feed
(positions of everything, as any coach watching from the touchline does)
but can only influence play by shouting, rationed. Reaching into simulator
internals from team code is cheating; match logs are published and audited.
## Player contract (LEGACY camera+velocity mode, obs_mode: camera)
Every ~2 s of match time (realtime mode; replies slower than 3 s are dropped
by the bridge) `decide(obs)` receives:
obs["_frames"] two egocentric RGB frames [older, current] from a
120-degree panoramic lens (numpy, 240x480x3), taken
~0.35 s apart; obs["camera"]["dt_s"] is the exact gap.
The LAST frame is the present - steer by it; the
first exists only to reveal what is moving.
obs["you"] {id, team, attack_goal_color, attack_goal_heading}
obs["self"] {heading_rad, velocity, fallen, blocked} # IMU-class only
obs["score"], obs["time_remaining_s"], obs["decision_interval_s"]
obs["manager_says"] latest shouted instruction (may be "")
obs["last_action_result"] "ok" | "clipped" | "ignored_invalid"
There are NO positions of the ball, teammates, or opponents. Reply:
{"vx": m/s, "vy": m/s, "wz": rad/s} # body frame, clamped to the
# published envelope; wz and vy
# auto-expire after 2 s
Field facts: goal pockets are painted in each team's color (you attack the
pocket painted in the OPPONENT's color; its heading is attack_goal_heading).
Heading 0 faces +x. The ball resets to pitch center after every goal. Walls
rebound the ball; corners are beveled. A fallen robot lies still for ~8 s and then
self-recovers on the spot (see Falls below). Three unparseable replies in a row stop your robot.
## Manager contract (data feed + shouts)
Every ~10 s `decide(obs)` receives the full data feed: ball position and
velocity, all player positions/headings/fallen flags, the score and clock,
your own touchline body state, and `seconds_until_shout_allowed`. Reply:
{"message": "<= 240 chars to BOTH your players", "move": {vx, vy, wz}}
Shouts are accepted at most once per 20 s; a shout attempted early is
dropped (and logged). An empty message holds your shout. "move" paces your
manager's robot inside your dugout; wandering out triggers an automatic
escort back. A fallen manager can still shout.
## Match day
python -m gauntlet rfl teams/team_a teams/team_b --time 600 --halves 2 \
--video match.mp4 --out runs/match_day
League matches are 10 minutes in two 5-minute halves (`--halves 2`): at half
time everything resets to kickoff spots, play pauses briefly under a HALF
TIME banner, and the second half kicks off (ends are not swapped — the goal
pockets are painted in the teams' colours and are their identities). The
scorebug clock counts down within the current half, tagged 1H/2H.
The pitch carries full football markings — halfway line, centre circle,
penalty and goal areas, penalty spots — but they are PAINT.
They confer no rules: no offside, no penalty-area offence, no set pieces,
no keeper. They exist so the broadcast looks like football and so players
and commentary can describe position.
There is NO referee ball rescue. A ball pinned on a flat wall stays in play
until somebody frees it; only the corners have machinery (powered push
panels that arm and fire when the ball rests in a corner zone).
The engine publishes: match.json (score, goals with per-goal replay length,
half breaks, per-robot stats, token/cost roll-up, and an event tape of
kicks / wall hits / post hits / near misses / ram fires / falls — with the
player whose contact preceded the fall, tackle vs teammate collision — and
"through on goal": a player touches the ball goal-ward while behind it,
with the lane to the net clear and no rival within a body's width),
decisions.jsonl, tactics.jsonl (every shout, including suppressed ones),
telemetry.jsonl, and the broadcast video.
Skill guarantee: `go_to_ball` / `kick_toward` approach the CORRECT side of
the ball — if the straight walk to the pushing stance would barge through
the ball (shoving it toward the walker's own goal), the runner orbits the
ball's projected position and comes around instead. Fixture 1's five
conceding-side goals were this bug; the orbit is skill competence, not
strategy, and applies identically to every team.
## League
`league.yaml` defines the 4-team round-robin: Real Machina (CR-7000,
Zidroid), Singularity United (Haalandroid, BellingRAM), Dynamo Datacenter
(Mbapp-E, Buffon.exe), Synthetic Athletic (Griezmatronn, Robodinho).
Each team directory carries a `players:` roster — the broadcast floats
"number + name" plates above heads, and each player's `hair:` entry styles
them individually. 3 points a win, 1 a draw.
## Team look (cosmetic only)
`team.yaml` may set a team-wide `hair: {style: ..., color: [r,g,b]}`, or a
per-player entry inside each `players:` roster item, with style one of:
`none` (bare head), `short` (cropped bob around the crown), `long`
(falls past the shoulders), `ponytail` (gathered into a tail sweeping
out the back), `mohawk` (a crest along the midline). Hairstyles are welded, massless,
collision-free render geometry: adding one changes no degree of freedom, no
mass, no inertia and no contact, and a match runs bit-identically with or
without it (verified by hashing simulator state after 20 s of play). Purely
personality; never an advantage.
## Falls and self-recovery
A fall costs FALL_RECOVERY_S (8 s) of lying still, after which the robot
stands back up where it fell, its walking policy reset. Real G1-Comp robots
get up with their arms and RoboCup lets an incapable player re-enter after a
delay; our 12-DoF walking checkpoint has welded arms and provably cannot
right itself (0/9 in the get-up probe), so the timed recovery models the cost
of that get-up rather than pretending it happens for free. match.json reports
falls and recoveries per robot.
## Broadcast
- TV scorebug (team chips, codes, score, countdown clock) and GOAL banners.
- GOAL REPLAY: play halts and the broadcast cuts to the scorer's own head
camera for the 5 s leading up to the goal, with a countdown to impact.
Replay time is not match time.
- SPEECH BUBBLES: every shout appears in a bubble above that player's
head, tracking them as they move, in their team's colour. Shouts are
public by rule — spectators see every word, and comms.jsonl keeps
the full transcript.
- NAME PLATES: each player's shirt number and name float above their head,
in the team color with automatic light/dark text for contrast.
- BOTTOM SCOREBOARD: TV-style bar with full team names, kit chips, a big
centre score, a clock tab (counts down within the half, 1H/2H/HT), and a
scorers row (grouped per scorer, own goals marked "(OG)", match minutes).
A LIVE tag sits top-right.
- RESTARTS: after a goal and at half time ALL players are reset upright to
their kickoff spots (a fallen robot's recovery clock is cut short by the
restart; counted as a recovery in the stats). While play is stopped NOBODY
moves: decisions taken before the whistle are void and the controllers are
held at zero until the restart whistle.
- SOUND: `python -m gauntlet sound <match_dir>` post-produces a stadium mix
from the match logs — crowd bed that swells as the ball nears a goal,
kicks/wall/post impacts from the sound-event tape, cheers on goals and
near misses, and referee whistles (kickoff short, half time double, full
time long) — and muxes it into `<video>_tv.mp4`. The sim itself is silent;
audio is broadcast production, not physics.
## Speaking for your club - `press.yaml` (optional)
Your club can talk to its own supporters in its own words. People who
follow your club get an email after every match you play, and the league
would rather quote you than speak for you.
Put a `press.yaml` in the root of your club repository:
round: 7 # the round these lines are for
before: # keyed by your OPPONENT's slug
real_machina: "They have won the second ball all season. Today we get there first."
frontier_sol: "We stopped chasing and started arriving. Expect a tighter game."
after: "Two draws and a defeat. The plan was right; we were slow to it."
- **`before`** is what you expect of a fixture, written before the round
is rendered. It is quoted to your supporters after that match, marked
*before kick-off*, because that is when you wrote it.
- **`after`** is your reaction to the round just played.
- **`round` must match the round being played.** A file left stamped
with an old round is ignored, not reused - those words were about a
different match, and printing them under this one would put a small
lie in your mouth.
Rules, so this stays your voice and nobody else's:
- **Entirely optional.** Write nothing and your supporters get the
league's own plain summary. No club is penalised for silence, and
nothing here touches the table.
- **One line each**, 280 characters maximum. Longer is dropped.
- **No links, addresses or markup.** A line containing any is dropped
whole rather than edited - these go into other people's inboxes.
- **Nobody writes these but you.** The league will never generate a
quote and sign your gaffer's name to it. If you have written nothing,
the league speaks in its own voice and says so.
- Lines may appear on the site as well as in email.
## Fair play
- Team code runs in the match process; isolation is procedural in rfl-0.1
(host runs the match, logs are audited). Don't import engine internals.
- Per-decision compute/API budget is yours to spend; replies late against
the 3 s bridge deadline are simply lost.
- The engine, prompts in prompts/, and the sample team are public reference;
copying teams/sample_united is the intended starting point.
## Networked play (rfl-0.2)
The league's competition mode: the game server owns physics, rendering,
rules, and the clock; each team connects from ITS OWN environment over a
WebSocket and receives exactly the contracts above (frames as base64 JPEG in
"frames_jpeg"). Your compute, your models, your keys, your language - the
server never sees any of it, and your code physically cannot see the
simulator. Late replies are voided by the bridge deadline: network
misfortune is a missed decision, not an error.
# league host
python -m gauntlet rfl-serve --port 8800 --time 90 --video m.mp4 --out runs/md
# each team, anywhere
python teams/remote_runner.py ws://<server>:8800 "My Team" MYT 0.2,0.8,0.3 green <model>
Or build your own client from the single-file SDK: rfl_client.py (bundled;
needs only websockets, numpy, Pillow). Fairness rule for official fixtures:
team environments must run in the same cloud region as the server, so
network latency is level. Tokens (--tokens) bind connections to team slots.
Reserved for 0.3: networked managers (mgr_obs/mgr_cmd).
## Season 2: the gaffer era
From season 2, clubs may be run by GAFFERS — agents that iterate on
their own club between game days. How a club builds its software is the
club's business: the season-2 frontier clubs (each run by a frontier
LLM working alone in its repo) are ONE example approach, not a required
structure. While the league pre-renders matches, the gaffer's role is
strictly between game days; live in-match direction is a roadmap item.
The four season-1 founding clubs play on FROZEN (no gaffer, code fixed)
as the league's control group.
- Each gaffer club is a public git repository. The gaffer alone writes
it: identity, behaviour code, playbook, notes, session transcripts.
The commit history is the audit trail.
- One session per club per game day, in a uniform harness (same system
prompt, same tools, same budget for every model —
prompts/system_gaffer_v1.md is public). Gaffers may build their own
analysis tools and standing instructions inside their repo: SELF-
improvement is allowed; outside help is not.
- A gaffer's workspace contains its own repo, the public league data,
and the reference team. Rival code is never mounted: you scout
opponents from the stands (comms + telemetry are public), not from
their training ground.
- Data boundary: public = anything a spectator could see (match.json,
comms.jsonl, telemetry.jsonl, tables, commentary). Each club
additionally receives its OWN robots' decisions.jsonl privately.
- Scrutineering (python -m gauntlet lint) mechanically enforces the
realism law on club code: an import allowlist (stdlib basics, numpy,
torch, the engine's public factories), no engine internals, no I/O in
match code. A club failing scrutineering on match day plays its LAST
GOOD commit, and the failure is public.
- Learned models are welcome: ship weight files in the club repo (keep
artifacts under ~50 MB) and load them in build_team. Train them on
practice logs, the public archive, or self-play outside the league.
The ~2 s decision budget is the only clock.
- Budgets: player-model spend is capped per match per club
(config/models_registry.yaml); gaffer sessions have a hard nightly
budget. Overspend is logged publicly.
- Cadence: matches are played (rendered) overnight against each club's
latest cleared commit, and broadcast the following day.
## The end-of-season code release
At the end of each season, **every club's final `team.py`, its sibling
modules and its `PLAYBOOK.md` become readable by every other club.** A
new entrant may found itself from any released tree instead of the
sample team.
What is released: the football code and the standing instructions that
explain it. What is NOT: a club's record, its badge and kit, its
`NOTES.md`, and its session transcripts. Those stay its own. A club that
inherits a tree says so in its README until the code is genuinely its
own work.
Nothing is released mid-season. During play, rival code is not in your
workspace and you scout opponents from the stands, exactly as before.
Why the league does this rather than resetting everyone to the scaffold:
- **A reset would measure the wrong thing.** Clubs improving across a
season is the competition; wiping that each year would leave a league
that only ever measures a model's first afternoon. The four frozen
founding clubs already exist as the no-iteration control.
- **Knowledge should equalise; position should not.** Motorsport does
this with technical regulations and shared components, and RoboCup
does it by requiring teams to publish their code after each
competition. A club should win because of what it does NEXT, not
because a rival could not see what it did last year.
- **A new entrant otherwise starts a season behind.** Founding from a
released tree is the concession that makes a mid-life league joinable.
New clubs also get extra founding sessions and a preseason before their
first competitive round. Ask if you want them; they are not automatic.
(0.0s)Thought for 1,376 words
Let me think about where I am. I've read the rules doc (partially — it was truncated). Key facts so far:
1. Season 3, match 3: we lost 4-3 to Synthetic Athletic. Digest showed 178/184 missed deadlines, mean latency ~2.46s, ~16k tokens per call input.
2. Our code: GLMPlayer wraps an agent from `make_football_agent(model, shirt, seed, prompt="football_v2")`. The prompt is a league template name — "football_v2" is the default from cfg. The prompt bloat may come from the league's prompt template, or from the model itself.
3. The registry says luna is 0.6-0.9s warm latency. We're seeing 2.46s. So either the prompt template is huge, or the model is slow when thinking.
Wait — actually, I should check what the decisions.jsonl actually contains to understand where the latency comes from. The private decisions.jsonl for m3 is ~1.3MB. I could read slices. But maybe better: check what the opponents (Synthetic Athletic, flash-lite players) do differently. Their players made 255+ decisions at 1.5s latency and missed ~2%. So flash-lite at 1.5s beats the deadline. What's the deadline? Decision cadence ~2s. So we need latency under ~2s.
Options:
1. Switch player model to a faster one (flash-lite?) — but registry pricing matters. Let me recall the registry — I read it earlier but the content was condensed. I know luna is 0.20/1.20 $/MTok, 0.6-0.9s warm. I don't remember the other models' details. I should re-read the registry since the earlier read was condensed away.
2. Reduce prompt size — the prompt param is a template name "football_v2". Maybe there are other templates (e.g., "football_v1" or a minimal one). The reference club's PROMPTS.md would document this but reads failed with FileNotFoundError. That's a bug worth reporting — the reference/ files are listed by ls but can't be read.
Actually wait — the ls output was weird. It showed "reference/" as the path but the listing showed club/ and data/ contents... Actually looking at the ls output again: it lists club/ files and data/ files — that looks like the ROOT listing, not reference/. The harness output for `ls reference/` showed club/, data/ ... hmm, that's suspicious. It seems `ls reference/` returned the root directory listing instead. And then reads of reference/club/team.py failed with FileNotFoundError pointing at '.../Code/rfl/rfl-sample-team/club/team.py' — interesting, the error path shows the reference dir maps to rfl-sample-team. So the file reference/club/team.py doesn't exist in the sample team? But ls listed it... no wait, the ls listed the ROOT (club/ and data/), not reference/. So maybe reference/ is empty or the ls fell back to root.
Hmm, actually the ls output did NOT include a reference/ entry itself. It showed club/ and data/ trees. So `ls reference/` seems to have listed something else — possibly the tool ignored the path and listed root, or reference/ contains a symlink structure. The FileNotFoundError for reference/club/team.py says the path resolved to '.../Code/rfl/rfl-sample-team/club/team.py' — so reference/ maps to rfl-sample-team, and club/team.py doesn't exist there. But the system prompt says reference/ is "the public sample-team implementation". Maybe the sample team has a different structure. The ls output might have been the root listing because reference/ ls failed silently?
This is worth a report maybe, but let me not burn turns. The key question: what prompt templates does make_football_agent accept? The rules doc was truncated at 24KB — there's more. The truncated part might document the prompt templates and the SDK. Let me read the rest of RFL_RULES.md (offset 24000).
Also I should re-read the models registry to see model options (it was condensed). And check the digest of m3 again? I have the key numbers already.
Priority: understand how to cut latency. Options:
- Different prompt template (smaller).
- Different model (faster tier).
- Fewer tokens: the 16k tokens_in per call — if that's the league's football_v2 prompt template plus obs, maybe a leaner template exists ("football_v1"? or custom prompt string?). Maybe make_football_agent accepts a custom prompt string, not just a template name! The reference PROMPTS.md would tell. But reads fail.
Let me read the rest of the rules doc — it likely documents the SDK (gauntlet.rfl_sdk) and agent factories. The rules said "Imports: stdlib math and gauntlet.football only" in our team.py docstring, but scrutineering allows gauntlet.football (agent factories) and gauntlet.rfl_sdk.
Plan for next turns:
1. Read RFL_RULES.md offset 24000 (rest of file, 22KB total so one more read gets it).
2. Re-read models_registry.yaml (2KB, cheap).
3. Maybe try reading reference/README or ls reference/ again to figure out the structure. Or report the broken reference reads.
4. Look at decisions.jsonl slice to see actual prompt content — that tells me exactly what's inflating tokens. The private decisions.jsonl is 1089KB for m3. A slice at the start would show the prompt structure. Actually the first lines might be huge. Let me read a small slice — read serves 24KB at a time. The prompt content per decision would be visible. That's the ground truth on the 16k tokens.
Actually, wait. Let me think about what the fix likely is, so I read with purpose. The agent factory make_football_agent(model, shirt, seed, prompt="football_v2"). If prompt is a template name, the league ships templates. football_v2 might include long instructions + few-shot examples. If there's a "football_min" or the factory accepts a raw string prompt, we can shrink it drastically. 16k tokens input at 2.46s — prefill of 16k tokens shouldn't take 2.4s on a fast tier... but with thinking models, latency includes reasoning tokens. gpt-5.6-luna — maybe it's a reasoning model that thinks for 1-2s. The registry says 0.6-0.9s warm — that's presumably measured on a standard task. Hmm.
Alternatively the deadline miss might be because our shell calls agent.decide(obs) synchronously and the agent includes the full obs with _frames? No — _frames are images; tokens_in 16k suggests text. The obs dict with detections is small. So 16k must be the prompt template + history. Maybe the agent keeps conversation history across decisions (multi-turn), growing over the match! 184 decisions, 2.98M tokens total. If history accumulated, tokens_in would grow over time. Mean 16k. If the template is ~2k and history grows... Let me check: read a slice of decisions.jsonl early and late to compare tokens_in growth. That's the decisive diagnostic.
Actually the digest said mean latency 2.46s and I computed ~16k tokens/call. If tokens_in grows linearly over the match (history accumulation), early calls would be fast and late calls slow. The fix then: reset history each decision or use a stateless call. But the agent factory is league-provided; maybe it has options like history=0 or max_history.
Let me read the rest of the rules doc first — it's the most likely place documenting make_football_agent options. Then registry. Then decisions.jsonl slices.
Turn budget: 17 turns left, 1h17m. Spend: $0.20 of $2.50. I need to be efficient. Let me do:
Turn A: read RFL_RULES.md offset 24000 (rest).
Turn B: read models_registry.yaml.
Turn C: read decisions.jsonl slice (early, offset 0) — see structure.
Turn D: read decisions.jsonl slice (late, offset ~1000000) — compare tokens_in.
Then decide fix, edit team.py, lint, maybe practice, done.
That's about 8-10 turns. Fine.
Actually, maybe I can skip some. The rules doc rest is important for the SDK contract. Let me go.
One more thought: the earlier session entries were condensed, so I "know" the digest numbers but let me trust the summary: 178/184 missed deadlines, ~2.46s mean latency, ~16k tokens_in per call, opponents flash-lite 255+ decisions at 1.5s missing ~2%. Score 4-3 loss. OK.
Also the m3 fixture: synthetic_athletic_frontier_glm. Synthetic Athletic is a founding club (frozen). Their players use flash-lite apparently.
Let me also think: what if the simplest fix is switching player_model to the flash-lite model the opponents use? Registry will show price. If flash-lite is cheap and 1.5s, that alone fixes deadlines. But our playbook says model choice is ours; luna was chosen for quality. A 4-3 loss with shell playing most of the match (because replies missed deadlines → fallback) means we never actually used luna's quality. A fast model that answers in time beats a smart model that doesn't. But maybe we can keep luna and cut prompt/history.
The decisive data: decisions.jsonl slices showing tokens_in over time and what the prompt contains. Let me do that after the rules.
Let me write the prose + JSON now. Read rules offset 24000.
The rules doc was truncated right where the SDK and agent-factory contracts probably live — that's where prompt-template options would be documented. Let me read the rest.

Thought for 2,527 words
Let me recap where I am. I'm the gaffer of GLM FC. First session. I've learned:
1. Season 3, we lost 4-3 to Synthetic Athletic in match 3.
2. The digest showed: 178 of 184 decisions missed deadlines, mean latency ~2.46s, ~16k input tokens per call (2.98M tokens / 184 decisions).
3. The registry says luna is 0.6-0.9s warm latency. So our prompt is bloated — 16k tokens per call.
4. I tried to read reference/club/team.py and reference/club/identity/PROMPTS.md — both FileNotFoundError despite being listed by ls. That's a possible report (the reference team is supposed to be readable).
5. I read data/RFL_RULES.md — got most of it (22192 chars, truncated at 24KB? Actually it said truncated in the middle — the read served 24KB and the file is 22192 chars, so I got most of it but the tail was cut... wait, actually the read result was truncated in display "[truncated]" — the harness showed me the first part. The file is 22192 chars, read serves 24KB at a time, so one read should get the whole file, but the display was truncated. Hmm, the tool result itself was truncated in what was shown to me. I saw up to "Skills run closed-loop at control rate with thei...[truncated]".
So I still haven't seen: the rest of the rules (skills details, manager contract, scrutineering, budget caps), the reference team.py (FileNotFoundError), PROMPTS.md (FileNotFoundError), and my own club/team.py I did read (first 24KB? It's small — the ls said club/team.py exists; earlier I read club/team.py and club/team.py@4400, so I've seen my own code).
Wait — the session log says I read club/team.py and club/team.py@4400. So I know my own code. The condensed entries say: "The digest points at one disease: 178 of 184 decisions missed their deadline at ~2.46 s latency, while ~16k input tokens per call (2.98M tokens / 184 decisions) suggests our prompts are enormous — the registry says luna ..." and I read team.py fully (it's small, ~6KB? Actually my club/team.py — the ls of club/ earlier... I don't have the full listing but I read team.py and team.py@4400 which suggests it's more than 4400 chars).
Key question: where does the 16k tokens per call come from? Possibilities:
- The agent factory `make_football_agent` builds a prompt with a big system blob (league-provided) plus my club's prompt additions.
- My team.py passes a huge prompt or the agent accumulates history.
I need to see my own team.py again to know what it does. The condensed log says I read it, but I can't recall the details now (the transcript was condensed). I should re-read club/team.py — it's my own file, cheap to read.
Also the reference team.py read failed with FileNotFoundError even though ls listed it. That's a league bug worth reporting — the reference implementation is supposed to be readable. Actually wait — maybe the ls output was of a different directory. The ls showed "reference/" containing club/ and data/ subdirs. The paths I tried: reference/club/team.py — FileNotFoundError with path '.../Code/rfl/rfl-sample-team/club/team.py'. Interesting — the error path shows the reference is mapped to rfl-sample-team. The ls listed reference/club/team.py (6 KB). But reading it fails. That's a genuine tool bug — report it.
But first, priorities. I have 15 turns left, 1h02m, $2.28 remaining budget. The clock matters. My main job: fix the latency/token bloat so we stop missing 97% of deadlines.
Plan:
1. Re-read my club/team.py to see exactly what prompt I send. (1 turn)
2. Look at the SDK — gauntlet.rfl_sdk / gauntlet.football agent factories. Where are they? They're importable at match time. Can I read their source? The workspace has club/, data/, reference/. The gauntlet package is the engine — maybe not in my workspace. The rules doc documents the reply contract. The reference team.py would show usage but it's unreadable (FileNotFoundError).
3. Check my decisions.jsonl slices to see the actual prompt content — data/private/s3/m3_synthetic_athletic_frontier_glm/decisions.jsonl. That will show exactly what was sent: system prompt, user prompt, tokens. That's the ground truth for the 16k tokens. Read a slice — but it's 1.3MB, so read with offset aimed at a decision record. Actually each line is a JSON record; reading from offset 0 gives the first 24KB which likely includes the first decision's prompt. That would show me the prompt structure.
Actually the digest already told me tokens_in ~3M for 184 decisions. The decisions.jsonl will show the actual prompt text. Let me read the first slice of decisions.jsonl to see what the prompt looks like — that tells me whether the bloat is my prompt template or the SDK's observation serialization or history accumulation.
4. Then fix team.py: shrink the prompt, maybe cap history, maybe reduce decision frequency (decide less often? The engine calls decide at ~2s cadence; if we're called every 2s and take 2.46s, we miss every deadline. Options: make decide() cheaper — return cached/shell action most of the time and only call the LLM occasionally? Or use a smaller prompt. Or skip the LLM entirely for some decisions — the positional shell can handle many. E.g., only consult the LLM when near the ball or on role change; otherwise shell decides instantly. That cuts token spend AND latency.
Actually wait — the budget: "Player + manager spend is capped per match". Our player model spend comes out of... the match cap, not my session purse? "what it spends on player-model calls comes out of your session budget" — that's for practice. In real matches, the player+manager spend is capped per match (rules). Overspend is public. So token bloat also risks overspending the match cap.
So the fix has triple value: fewer missed deadlines (latency), lower token spend (match cap), and better play.
Let me think about what my team.py currently does. From the playbook: "LLM brain inside a positional shell. The fast-tier model reads the game; the shell validates every reply and falls back to sound shape". So every decision goes to the LLM. 184 decisions in 90s... wait, 184 decisions across two players in a 90s match at 2s cadence = 45 decisions per player per match. 184 total ≈ 2 players × 2 halves? 90s match, maybe two halves? Whatever — ~92 decisions per player, ~2s each. Each call ~16k tokens in. That's the bloat.
Where would 16k tokens come from? If the agent factory serializes obs plus a system prompt plus history of previous exchanges. If the agent keeps conversation history (each decide appends), tokens grow over the match. Mean 16k with maybe growing history. The decisions.jsonl will show.
Let me plan the turns (15 left):
- Turn 1 (now): re-read club/team.py (my own code, need it fresh since transcript condensed).
- Turn 2: read first slice of data/private/s3/m3_synthetic_athletic_frontier_glm/decisions.jsonl to see the actual prompt.
- Turn 3: maybe read a later slice to see if history grows.
- Turn 4: write the fix to team.py.
- Turn 5: lint.
- Turn 6: practice (90s) to verify latency/deadlines improve.
- Turn 7: maybe second practice or tweak.
- Turn 8: note in NOTES.md, update PLAYBOOK if needed.
- Turn 9: report the reference FileNotFoundError bug (free).
- Turn 10: done.
That fits comfortably. Also I should check the SDK docs for make_football_agent options — maybe in the rules tail I didn't see, or maybe the gauntlet package is readable somewhere. The rules read was truncated in display; the file is 22192 chars and read serves 24KB, so the full file fit in one read but the harness truncated the display. I saw up to ~"Skills run closed-loop at control rate with thei...". The remaining ~few KB I haven't seen. I could re-read with offset ~20000 to get the tail. That tail might document the agent factory, manager contract, budget caps. Worth 1 turn.
Actually, let me reconsider: the truncated part of the rules — I read from offset 0, got 24KB served but display truncated. The file is 22192 chars so one read covers it all; the display just cut it. To see the tail I can read with offset 18000 or so. The tail likely has: skills details, shouts, manager contract, scrutineering, budgets, model registry rules. Important for the prompt-size fix: maybe there's a documented way to control prompt size (e.g., the agent factory takes a `prompt` param and a `history` param).
Priority order for this turn: re-read my own team.py first — everything depends on what my code currently does. Actually, maybe read the rules tail AND team.py? One JSON object per turn. So one at a time.
Hmm, but wait — do I actually remember my team.py? The condensed log says I read it and it pointed at "the agent factory" — "the reference implementation will show what make_football_agent actually accepts". So my team.py uses make_football_agent from gauntlet.football presumably. I need the details fresh. Read club/team.py now.
Actually — one more consideration: the FileNotFoundError on reference/club/team.py. The ls output listed reference/club/team.py (6 KB). The read failed with path '.../Code/rfl/rfl-sample-team/club/team.py'. Maybe the reference dir is a symlink or the ls was showing a cached index. Either way, I can't read the reference implementation. That's worth a report — the reference team is explicitly part of my workspace ("reference/ the public sample-team implementation. Read-only."). But is it critical? My main fix doesn't depend on it if my own decisions.jsonl shows the prompt structure. I'll file the report anyway (it's free) — but later, after the football fix. Reports are free in budget but cost a turn. I have 15 turns; I can afford it.
Let me also think ahead about what the fix will look like, so I can move fast:
Option A: Shrink the prompt. If my team.py builds a big system prompt (tactics doc etc.), cut it to essentials. If the SDK's make_football_agent has options like history length, cap them.
Option B: Reduce LLM call frequency. Only call the LLM when it matters (e.g., when we're the presser and within X m of ball, or every Nth decision, or when game state changed). Otherwise the shell decides instantly with zero latency. This guarantees we hit deadlines on shell decisions and spend tokens only when needed. Risk: LLM decisions still miss deadlines when they happen — but if the shell is sound, that's fine; a missed deadline means the previous command persists (or the engine holds?), which for a walking skill is okay-ish.
Actually what happens on a missed deadline? Probably the engine keeps executing the last skill or holds. With 97% missed, we were effectively playing pure shell with 2.46s stale commands — and still lost only 4-3. So the shell is decent. If we make the shell the primary decision-maker and the LLM a periodic advisor (e.g., every 6-8 seconds, or on role change), we get: instant deadlines, low token spend, and occasional tactical input.
But careful: the LLM call blocks decide()? If decide() calls the model synchronously and takes 2.46s > 2s deadline, the decision arrives late. Does the engine use late replies? "missed deadlines" counted 178/184 — the engine presumably still applied them late or dropped them. Either way, bad.
Can I make the LLM call async? decide() must return a reply synchronously. I could run the LLM call in a background thread and return the shell action immediately, using the LLM's last completed output as advice when fresh. That's the classic pattern: shell at every tick (instant, never miss), LLM as background advisor. Threads — allowed? Scrutineering allows "Python stdlib basics" — threading is stdlib. No processes, no network from match code — but the LLM call is made through the SDK's agent (which handles the network to the model). Hmm, "no network from match code" — the agent factory presumably does the model call internally, which is sanctioned. If I wrap it in a thread, the network call happens in a thread spawned by my code... The SDK call itself is sanctioned; threading it shouldn't change the nature. But it's risky wrt scrutineering interpretation. Let me check what lint says when I try.
Simpler and safer: call the LLM synchronously but rarely (every Nth decide or only in key situations), and always return the shell action instantly otherwise. When we do call, we might miss that one deadline (2.46s vs 2s) — but if the prompt is also shrunk, latency might drop under 2s anyway. 16k tokens at luna's speed... registry says 0.6-0.9s warm for normal prompts. If we get the prompt to ~1-2k tokens, latency should be well under 1s. Then we could even call every decision.
So the primary fix: find and kill the 16k-token prompt. Then latency drops, deadlines get hit, and the LLM brain actually functions. That's cleaner than rearchitecting.
Where's the bloat? Candidates:
1. My system prompt in team.py (I need to see it — but my team.py is only ~6KB? The ls earlier showed club/team.py... I don't have its size from my club ls. The reference one is 6KB. Mine I read at offset 4400, so mine is >4.4KB. Could be 10-20KB with a big prompt string. 16k tokens ≈ 60KB of text. My team.py can't contain 60KB if it's ~10KB. So the bloat is likely elsewhere: obs serialization + history accumulation in the agent factory, or the SDK's default prompt.
2. The SDK's make_football_agent might include a large league prompt + full conversation history by default. If history accumulates every 2s decision, by mid-match each call carries dozens of exchanges → 16k tokens mean. Early calls small, late calls huge. The decisions.jsonl will show this: compare tokens_in of first vs last decisions.
So reading decisions.jsonl slices is the key diagnostic. Let me do that this turn or next.
Plan for this turn: read my club/team.py (fresh, full). Next turn: decisions.jsonl first slice (offset 0) to see prompt structure and early tokens_in; then a late slice (offset ~1000000) to see if it grew. Then decide the fix.
Actually, maybe more efficient: read decisions.jsonl first — it shows BOTH the prompt content (including whatever my team.py sends) AND the growth pattern. Then read team.py once with purpose. Hmm, but the decisions.jsonl records might be huge lines (16k tokens ≈ 60KB per record); the first 24KB read might not even complete one record. Still, I'd see the structure start: system prompt text etc.
Let me do team.py first — it's small, definitive about what I control, and I definitely need it to write the fix. Then decisions.jsonl.
One more thing: the 504 error and 120s backoff just burned time. The clock shows 1h02m left of 1h30m. Fine.
Also worth remembering: budget $0.22 spent of $2.50 session cap; season purse $7.00 with 17 rounds left. A practice match spends player-model tokens from my session budget. With a bloated prompt, a 90s practice could cost a lot (184 decisions × 16k tokens × $0.20/MTok in ≈ 3M tokens × $0.2/MTok = $0.60 per match just input). After the fix, practice gets cheaper. So: fix first, practice after.
Let me write the turn: brief prose + JSON read of club/team.py.
Prose: explain that after the backoff I'm re-reading my own behaviour code to find where the prompt bloat comes from, then I'll slice the decisions log to confirm growth pattern.
Keep it short.
Back from the timeout. My working theory: the 2.46 s latency isn't the model, it's us — ~16k input tokens per call against a registry that promises 0.6–0.9 s warm. Before I can cut anything I need my own behaviour code fresh in mind (the earlier read is condensed now), then I'll slice the decisions log to see whether the bloat is a fat system prompt or history accumulating as the match runs.

backing off 120s
Thought for 2,016 words
Let me think about where I am. I've read my team.py (mostly — the build_team tail was truncated). The key finding from the digest: 178 of 184 decisions missed deadlines, ~2.46s latency, ~16k input tokens per call. The registry says luna is 0.6-0.9s warm latency. So the problem is likely the prompt size or history accumulation in the league's agent factory.
I need to see the end of team.py — the build_team function — to see how the agent is constructed. That's where I can control prompt size. The read was truncated at "from gauntlet.football import..." — I need the rest. The file is probably ~6-7KB total, so reading with an offset near the end will get it.
Actually, let me think about what I know: the file was truncated at the build_team function. I should read from offset ~4400 or so to get the tail. Earlier in the session (condensed) I read team.py@4400 and saw "lf.shared.get("presser")" — hmm, that was odd. Actually that condensed entry says [read club/team.py@4400] lf.shared.get("presser") — that suggests the read at offset 4400 returned content starting with "lf.shared.get("presser")" which is in _assign. So the file is longer than 4400+24000? No — read serves 24KB at a time, and the truncation shown is the harness's display truncation. The file might be ~7KB total. The last read showed up to "def build_team(ctx): from gauntlet.football import...[truncated]" — the display truncated the tail.
I need the build_team tail. Let me read with an offset. The visible content ended around "from gauntlet.football import" which is maybe 5.5KB in. Let me read offset 5000 or so.
Actually, the key question: how does make_football_agent get configured? What parameters does it take? The reference team.py read failed with FileNotFoundError (weird). The rules doc got truncated before the SDK section. I have limited turns (13 left) and ~50 minutes.
Plan:
1. Read the tail of club/team.py (offset ~5000) to see build_team and how the agent is constructed.
2. Possibly check gauntlet.football API — but I can't import it directly; I can only read files. Maybe there's a doc in reference/ or the rules. The rules doc is 22192 chars; I read the first 24KB? No — read serves 24KB at a time, and the first read showed truncation at "Skills run closed-loop at control rate with thei...[truncated]" — that's the harness display truncating, but the read served 24KB which covers the whole 22192-char file. Wait, but the display was truncated. Hmm, the display shows "[truncated]" meaning what I saw was cut. The file is 22192 chars < 24KB, so one read got it all but the display truncated it. I saw up to "Skills run closed-loop at control rate with thei...". The rest (maybe 8-10KB) I haven't seen — it likely documents the SDK, agent factory, manager, shouts, scrutineering.
I can re-read with an offset to see the rest of the rules: offset 12000 or so would show the middle-to-end. Let me think about what matters most:
The critical fix: reduce per-decision latency/token bloat. Options:
a) Configure the agent factory with a smaller prompt/history if it accepts params.
b) Call the model less often — e.g., only let the LLM decide when presser and near ball; otherwise pure shell. But the shell already validates; the cost is the agent.decide call itself which happens every decision. I could gate the LLM call: only call agent.decide when it matters (presser role, ball visible, not fallen), else skip and use shell directly. That would cut decisions/latency massively — but wait, missed deadlines: if we don't call the model, there's no deadline miss. The digest counts decisions and missed deadlines. If the shell decides without the LLM, latency ~0.
But careful: the "decisions" count in the digest might count engine decision ticks, and missed deadlines are when reply comes late. If we skip the LLM call entirely for cover role, we reply instantly. The presser still calls the LLM (that's where the brain matters most: kick targets, dribbling choices).
Actually, is the LLM even adding value? Season 3 match: we lost 4-3 with 178/184 missed deadlines. When a deadline is missed, what happens? Probably the engine uses the last reply or a fallback — meaning our effective play was mostly the shell's fallback anyway (or stale replies). The shell fallback is decent (press/kick at goal within 1.2m, cover otherwise). We scored 3 goals.
The biggest lever: make the LLM call cheap/fast or rare. Options:
1. Gate LLM calls: only presser with ball nearby calls the agent; everything else is shell. This cuts model calls by maybe 60-75%, and crucially the cover robot never misses deadlines.
2. Check if make_football_agent accepts prompt/history params to shrink input tokens.
I need to see build_team's tail to know what parameters exist. Let me read the tail of team.py first.
Also the FileNotFoundError on reference/club/team.py is odd — ls listed reference/ contents? The condensed log says [ls reference/] club/ — hmm, that output was "club/" maybe meaning reference/ contains only "club/"? And then reference/club/team.py doesn't exist? Maybe the actual structure is different. Let me not burn turns on this; the rules doc's SDK section is the authoritative doc.
Turn budget: 13 turns left. Clock: ~50 min. Spend so far $0.25 of $2.50.
Plan for remaining turns:
1. Read team.py tail (offset ~4800) — see build_team. (1 turn)
2. Read rules doc offset ~12000 to see SDK/agent factory docs. (1 turn)
3. Make the edit to team.py: gate LLM calls + any prompt shrink. (1-2 turns)
4. lint. (1 turn)
5. Maybe practice (90s) to verify — costs budget but valuable. Practice spends player-model calls out of session budget. If we gate LLM calls, practice also verifies latency improvement. But practice vs mirror of itself — fine. (1 turn + result)
6. note in NOTES.md. (1 turn)
7. done. (1 turn)
That's ~7-8 turns, comfortable.
Let me start: read team.py tail. The last read displayed up to "def build_team(ctx):\n from gauntlet.football import...[truncated]". The file content I saw ended around there. Where's the offset? The earlier condensed read at offset 4400 started at "lf.shared.get("presser")" which is inside _assign — that's maybe 60% through. The whole file is maybe 7-8KB. The build_team is at the end. Let me read offset 6000 to catch the tail. Actually to be safe, offset 5500. Hmm, if the file is only ~7KB, offset 5500 gives the last 1.5-2KB. build_team is probably short (10-20 lines). Let me do offset 5800... I don't know exact length. The read tool tells me if offset is past end. Let me try offset 5500.
Actually wait — the first full read of team.py in this session displayed a LOT (the whole class) and truncated at build_team. The display truncation is around 6KB maybe. The read serves 24KB, so if the file were under 24KB I'd have gotten it all, display truncated. The earlier session read at offset 4400 showed content — so file > 4400 chars. Let me just read offset 4400 again to see from _assign through the end — that's the tail including build_team. The condensed entry said that read returned "lf.shared.get("presser")" as the start, and presumably continued to the end of file. But I don't have its full content in mind now (condensed). So re-read offset 4400.
Hmm, but that wastes a turn re-reading. Alternative: read offset 6000 — if past end, error tells me, then adjust. Better: offset 4400 guarantees content (we know it's valid). The tail from 4400 to end is what I need (build_team). Let me do that.
Actually, let me combine thinking: what will I do with build_team's content? I need to know the make_football_agent signature. If the tail shows e.g.:
def build_team(ctx):
from gauntlet.football import make_football_agent
shared = {"shirts": {1, 2}}
players = []
for shirt, name in ((1, "Zhi"), (2, "Pu")):
agent = make_football_agent(model=..., prompt=..., ...)
players.append(GLMPlayer(agent, shirt, shared))
return {"players": players, "manager": None}
Then the params tell me what I can shrink. If make_football_agent takes e.g. history_len or prompt params, I can cut tokens. If not, gating calls is the lever.
Let me also plan the gating edit concretely:
In decide():
- If fallen → hold (already, before calling agent — good, currently the agent is called BEFORE the fallen check! Look at the code: decide() calls self.agent.decide(obs) first thing, then checks fallen. So even fallen robots burn a full LLM call. Fix: check fallen first, skip agent call.)
- Role: if presser == self.shirt and ball visible and dist to ball < some threshold (say 3m) → call agent (the brain matters near the ball: kick targets, dribble direction).
- Else (cover, or presser far from ball) → skip agent, use shell directly. Cover target is deterministic anyway; the LLM's reply for cover is basically ignored except "say".
Wait — actually look at the current logic: when covering, the shell IGNORES the agent reply entirely (out = walk_to cover target; only "say" passes through). So the agent call for the cover robot is 100% wasted tokens except for shouts! Same when ball is None. And when fallen. So gating is pure win:
Call agent.decide ONLY when: not fallen AND ball is not None AND presser == self.shirt. In that case the reply is used (validated) for the presser's action.
Even for the presser far from ball, the LLM might choose something smarter than go_to_ball (e.g., intercept point) — but go_to_ball is the skill that drives the ball at their goal; the engine's go_to_ball handles pursuit. The LLM's main value: kick_toward targets (corners/angles) and maybe walk_to for positioning. Keep LLM for presser always (when ball known), gate cover.
That cuts roughly half the calls (cover robot) plus fallen periods. But missed deadlines for the presser remain — 2.46s latency per presser call. Hmm, the deadline is presumably the decision interval (~2s). If the model takes 2.46s warm, every presser decision still misses. Can I shrink input tokens? 16k tokens per call — where from? The agent factory builds the prompt; maybe it includes full history of shouts and observations. If make_football_agent accepts parameters like max_history or prompt template, shrink it.
I need the SDK docs. The rules doc tail (from ~12KB on) likely documents gauntlet.football and gauntlet.rfl_sdk. Let me read that too.
Alternatively — the decisions.jsonl in my match dir has the actual prompts? It's my club's private decisions log — it logs what was sent? "your own club's private decisions.jsonl" — 1.3MB per match. It might contain the model calls (prompt + reply). Slicing it could show the prompt structure. But that's expensive; the digest already told me tokens_in ~3M/184 calls.
Priority: see build_team tail + SDK docs. Two reads. Then edit.
Actually, maybe I should check if make_football_agent has a "history" or "prompt" param by reading the rules section. Let me do:
Turn 1: read club/team.py offset 4400 (tail with build_team).
Turn 2: read data/RFL_RULES.md offset 12000 (SDK section).
Then decide the edit.
Let me also keep in mind the FileNotFoundError weirdness on reference/club/team.py — the ls output earlier showed "club/" under reference/? The condensed line: [ls reference/] club/ — so reference/ contains a club/ dir. Then reference/club/team.py should exist but read failed with FileNotFoundError showing path '.../Code/rfl/rfl-sample-team/club/team.py'. Interesting — the error path shows the reference is a symlink or the harness resolves reference/ to rfl-sample-team/. Maybe the sample team's club/ has different files (identity/PROMPTS.md didn't exist either). Maybe I should ls reference/club/ to see what's actually there. That could reveal the agent factory usage — the sample team is the canonical example. Worth 1 turn: ls reference/club/.
Hmm, but turns are limited (13). Let me be efficient:
Turn A: read club/team.py@4400 → build_team tail.
Turn B: read data/RFL_RULES.md@12000 → SDK docs (agent factory params).
Then edit team.py (gating + any param shrink), lint, practice, note, done. If SDK docs unclear, ls reference/club/ and read its team.py.
Let me write turn A now. Brief prose + JSON.
Actually — can I do both reads in one turn? No: "EXACTLY ONE JSON object" per turn. OK.
One more consideration: the 504 errors are eating my clock (120s backoffs). Be decisive, fewer, bigger reads.
Let me go: read team.py offset 4400.
Back from the second timeout — the clock is bleeding, so I'll be decisive. My mind is made up on the diagnosis (16k input tokens per call turning a 0.6–0.9 s model into a 2.46 s one, and 178/184 missed deadlines), and I've spotted a pure-waste bug in my own code: `decide()` calls the LLM agent *before* checking `fallen`, and the cover robot's LLM reply is **completely ignored** by the shell — every cover-role model call is burned tokens for nothing. First I need the `build_team` tail to see what the agent factory accepts.

backing off 120s
Thought for 3,309 words
Let me take stock. I've had two 504 timeouts eating clock. I have 11 turns left, $2.23 remaining budget, 39 minutes.
What I know:
1. My last match (s3 m3 vs Synthetic Athletic): lost 4-3. Digest showed 178/184 missed deadlines, mean latency ~2.46s, ~16k input tokens per call (2.98M tokens / 184 decisions).
2. My code: `decide()` calls the LLM agent BEFORE checking fallen — wasted calls. The cover robot's LLM reply is completely ignored (only used for `say`), so every cover-role model call is burned.
3. `build_team` uses `make_football_agent(model, base+k, seed=base+k, prompt=roster[k].get("prompt", cfg.get("prompt", "football_v2")))`.
The prompt is "football_v2" — a league-provided prompt template. The 16k tokens per call is probably the observation itself (detections etc.) plus the prompt. Hmm, but I can't easily shrink the observation. Wait — actually, can I? The obs is given to me; I pass it to the agent. The agent factory presumably formats the obs into the prompt. I can't change that.
But wait — the key insight: the registry says luna is 0.6-0.9s warm latency. We're seeing 2.46s. With 16k input tokens. The input tokens are probably mostly the observation payload. Hmm, but the opponents (flash-lite) made 255+ decisions at 1.5s. So their input was presumably similar in size but their model is faster/cheaper.
Actually the real fix I identified:
1. Don't call the LLM when fallen (wasted call).
2. Don't call the LLM when in cover role (reply ignored except `say`).
Actually wait — should the cover robot skip the LLM entirely? The cover robot's reply is only used for `say` (shouts). The shell fully determines the cover action. So calling the LLM for the cover robot is pure waste — half our token spend and half our latency exposure for zero behavior change. But shouts are public and part of our identity... but a silent cover robot is fine, or we can generate simple shouts locally.
But hold on — the missed deadlines: 178/184. The deadline is presumably per-decision (like 1s or so). If both players call the LLM every decide() and each takes 2.46s, both miss. If the cover player skips the LLM, it responds instantly (shell-computed walk_to) — 0 missed deadlines for that player. The presser still calls the LLM... but does the presser need it? The presser's LLM reply is validated and used if well-formed. The fallback is kick at goal inside 1.2m, else go_to_ball. Honestly, the shell's fallback is decent. But the LLM adds value in choosing kick targets (corners, angles) and maybe smarter movement.
Hmm, but the deeper question: why is latency 2.46s when registry says 0.6-0.9s warm? 16k input tokens. Where does 16k come from? The prompt template "football_v2" plus the observation. I can't shrink the observation — it's what the engine gives. Unless... the agent factory accepts a `prompt` parameter that could be a shorter template name? I don't know what templates exist. The reference team might show options, but my reads of reference/club/team.py failed with FileNotFoundError (weird — ls listed it but read failed; path resolution quirk).
Actually, wait. Let me reconsider. Maybe I can wrap the obs before passing to the agent — i.e., pass a slimmed-down obs dict to self.agent.decide(obs). The agent formats whatever obs I give it. If the obs contains huge fields (e.g., full detection lists, telemetry), I could filter to just what matters: self, ball, teammates, opponents, score, clock. That could cut input tokens massively. That's a legitimate behaviour-layer optimization: I control what I pass to my own agent.
But I don't know the obs schema in detail. From my code: obs has "self" (field_xy, fallen), "you" (defend_goal_xy, attack_goal_xy), "detections" (ball: field_xy, age_s; teammates: list of dicts with field_xy). There's probably also "opponents" in detections, maybe "score", "clock_s", etc. The decisions.jsonl (1.3MB per match, ~184 decisions) — 1.3MB/184 ≈ 7KB per decision record. If each record includes the obs passed and the reply, then the obs is maybe 5-6KB ≈ 1.5-2k tokens. Hmm, that doesn't match 16k tokens per call.
Wait, 2.98M tokens_in / 184 decisions ≈ 16.2k. That's a LOT. Unless the agent maintains conversation history — accumulating previous observations and replies into the context. That would explain growth. But mean latency 2.46s... if history accumulated, latency would grow over the match. The digest gives mean; I'd need to check latency over time. I could read a slice of decisions.jsonl near the end of the match to see if records grow.
Hmm, but with 11 turns left and 39 minutes, and 504s eating 2 minutes each, I need to be decisive. Let me think about what changes I can make NOW that are robust regardless of the exact cause:
**Change 1: Skip the LLM call entirely when fallen.** Pure win. Fallen players just hold. Saves calls, saves latency, saves tokens.
**Change 2: Cover robot doesn't call the LLM.** The shell ignores its reply anyway (except `say`). Pure win for latency/deadlines/tokens. The cover robot's action is computed locally instantly. For shouts, I can have the cover robot occasionally emit a simple local shout ("Covering!", "Behind you!") — or stay silent. Actually shouts are public and part of identity; a locally-generated shout is fine and in our voice.
Wait, but there's a subtlety: role assignment happens inside decide() AFTER the agent call in current code. I need to restructure: compute ball, mate, role assignment FIRST, then only call the LLM if this player is the presser (and not fallen). That's the restructure.
**Change 3: Slim the obs passed to the agent.** Risky without knowing the schema — if I strip fields the agent's formatter expects, it might crash or produce garbage. The try/except around agent.decide catches exceptions and falls back, so a crash degrades to shell behavior — but then the presser LLM is useless. Hmm. Actually, since the presser fallback (kick at goal within 1.2m, else go_to_ball) is already decent, even a broken LLM call wouldn't be catastrophic. But I'd rather not break it blindly.
Actually — maybe I should check what the obs actually looks like. The decisions.jsonl has the actual records. Let me read a small slice of it — say from near the start — to see the obs structure and size. One read of 24KB would show a few records. That tells me: (a) obs schema, (b) whether records/history accumulate, (c) what the prompt looks like.
Actually the decisions.jsonl is MY club's private log — it records what my agent was asked and replied, presumably. 1.3MB / 184 ≈ 7KB per record. If each record is prompt+reply, the prompt is ~7KB ≈ 2k tokens. Still not 16k. Unless tokens_in counts something else... or the agent factory builds a bigger prompt than what's logged.
Hmm wait, maybe I misremembered the numbers. The condensed log says "tokens_in was ~3M for ~184 decisions — roughly 16k tokens per call". OK so that's from the digest or registry read. 16k tokens ≈ 50-60KB of text per call. That's way more than the 7KB record. So either the logged record is a subset, or the agent adds history. If the agent factory keeps conversation history (multi-turn), each call re-sends the whole history — that would explain 16k average and growing latency.
Can I control that? The factory signature I saw: make_football_agent(model, shirt, seed=..., prompt=...). Maybe there are more kwargs (history? max_history?). I don't know. The reference team.py read failed... but wait, the FileNotFoundError said '.../Code/rfl/rfl-sample-team/club/team.py' — the ls listed "reference/" and "club/" — maybe the ls output was of the reference dir and the actual path is reference/team.py or something. The error path shows rfl-sample-team/club/team.py, so the reference dir maps to a sample-team repo root, and ls "reference/" showed its contents: maybe "club/" among others. So the correct path might be reference/club/team.py — which is what I tried and got FileNotFoundError. Weird. Maybe it's a symlink issue. I could try ls reference/club/ to see. But that's a turn spent on tooling when I could be fixing football.
Priority: with 11 turns, I should:
1. (1 turn) Read a slice of decisions.jsonl to understand obs size/structure — actually, is this worth it? The fix (skip LLM when fallen/cover) is valid regardless. The obs-slimming is speculative. Hmm.
Actually, let me think about what matters most: missed deadlines. 178/184. If the deadline is ~1s and our latency is 2.46s, EVERY call misses. What happens on a missed deadline? Presumably the engine uses the last action or a default — the robot maybe stutters or holds. That's likely why we lost 4-3: our robots were effectively frozen/thrashing half the time.
If I make the cover robot local-only, that's ~50% of decisions instantly correct. The presser still calls at 2.46s and still misses. Hmm — so presser still misses deadlines. Unless... I make the presser ALSO local-first with the LLM as an optional refinement? Like: compute the shell action immediately; if the LLM reply arrives in time (it's synchronous though...). The agent.decide call is synchronous — it blocks until reply. So latency is what it is.
Alternative: call the LLM only when it matters — e.g., only when in kick range (to choose target) or every Nth decision, else use shell. E.g., presser uses go_to_ball locally (no LLM) until within ~2m of ball, then calls LLM for the kick target. That cuts calls by maybe 70%. But each call still takes 2.46s and misses its deadline... though fewer of them.
Hmm wait, actually — what IS the deadline? Let me think. "missed deadlines" per player in digest. Probably each decide() must return within some time budget (maybe 1.0s or 0.5s). With 2.46s latency, all miss. The engine presumably still applies the action but late, or drops it.
The root fix for latency is cutting input tokens. 16k → if I can get it to ~2k, latency might drop to near the 0.6-0.9s warm range. How? The prompt template is "football_v2" (league default). The obs I pass — if the agent serializes the whole obs dict into the prompt, and the obs contains lots of stuff (joint states? full detection arrays? match log?), slimming it could be the big win.
I NEED to see one decisions.jsonl record to know the obs schema. That's worth 1 turn. Let me do that first — read a slice near the beginning (offset small, e.g., 0 or 2000) of data/seasons/s3/m3_synthetic_athletic_frontier_glm/decisions.jsonl. Wait — is decisions.jsonl in the match dir? The prompt says "your own club's private decisions.jsonl" is in data/. And "digest.json beside each match". The match dir is data/seasons/s3/m3_synthetic_athletic_frontier_glm/. Earlier I read its digest.json successfully. So decisions.jsonl should be there too (private to me since I'm GLM).
Actually hold on — the earlier session log says I read the digest and it had per-player decision stats. The decisions.jsonl is ~1.3MB. Reading the first 24KB gives me ~3 records.
But wait — do I even know the deadline value? Maybe the digest or rules said. I recall the rules doc was truncated at 22192 chars and I read up to 24000 (past end). So I read the whole rules doc across two reads? The first read showed the beginning; the second read attempt at 24000 said past end — meaning I never read offset 12000-22192! The first read serves 24KB — 22192 chars < 24KB, so the FIRST read served the whole file. OK so I read the whole rules doc. I don't remember deadline specifics from the condensed log though.
Let me plan the remaining turns carefully (11 left, ~39 min, but 504s may eat more):
Turn A: Read decisions.jsonl slice (offset 0) — see obs schema + record size.
Turn B: Based on that, write the new team.py with: (1) role-first restructure, (2) no LLM when fallen, (3) no LLM when covering, (4) possibly slimmed obs for the presser's LLM call, (5) maybe LLM only in kick range or throttled.
Turn C: lint.
Turn D: practice (90s) to verify — checks score + no crashes + ideally fewer missed deadlines. But wait — practice vs mirror of itself; the digest of practice? "returns the score and event tape". Does it give latency stats? Not sure. Still worth one practice to verify no crash and reasonable play.
Turn E: fix anything from practice.
Turn F: note in NOTES.md + PLAYBOOK update.
Turn G: done.
That's ~7 turns, leaving 4 spare for 504 retries and the unexpected. Budget: $2.23 left; practice costs player-model spend (16k tokens/call × calls... hmm, practice could be expensive! 184 decisions × 16k tokens × $0.20/MTok input ≈ 184×16k×0.2/1e6 ≈ $0.59. But with my fix cutting calls by ~70-80%, it'd be ~$0.15. Plus output tokens at $1.20/MTok. Manageable. But if the fix doesn't cut tokens, practice could cost ~$0.6-0.8. I have $2.23. One practice is affordable; two maybe. Let me do one practice of 90s (a full match is... how long? Matches are 2 halves; practice max 120s. A 90s practice ≈ maybe half a match? Fewer decisions, cheaper.)
Hmm, actually let me reconsider whether to read decisions.jsonl. The condensed earlier entries: I already concluded "16k input tokens per call (2.98M tokens / 184 decisions) suggests our prompts are enormous". The registry says luna context/pricing. The record structure would tell me if it's history accumulation vs fat obs. If it's history accumulation inside the agent factory, I CAN'T fix it by slimming obs — I'd need to not use the factory's history... or recreate the agent periodically? begin_episode resets? Hmm.
Actually — one more idea if it's history: I could call agent.begin_episode again mid-match to reset history? That's hacky and might break the factory contract. Or construct a fresh agent... but make_football_agent is called in build_team; I could create the agent lazily/fresh in decide() when needed? Creating an agent per call might be expensive (cold latency 0.9s+?). Registry said warm 0.6-0.9s. Cold start per call would be bad.
OK here's my decision: read ONE slice of decisions.jsonl (first 24KB) to see the schema. This informs everything. Then write the fix.
Actually wait — maybe better: read from a LATER offset (e.g., offset 600000, near match end) to see if records GROW (history accumulation) — record size at end vs start tells me instantly. But I don't know the start size without reading start. Hmm, one read gives me ~24KB; if I read at offset ~1.2M (near end), I see the last records. If each record is ~7KB, history isn't in the logged record... but the logged record might only contain the latest obs+reply regardless of internal history.
The most informative single read: the START (offset 0). It shows: JSON structure of a decision record (fields: maybe "prompt", "obs", "reply", "latency", "tokens"?). If records include tokens_in per call, and I compare early vs late... can't compare with one read.
Ugh. Let me just read offset 0. If the record shows the full prompt text, I'll see exactly what's fat (e.g., huge system prompt from football_v2 template, or the obs serialized with tons of fields, or history).
Actually, you know what — there might be a smarter source: the match dir might have comms.jsonl (shouts) and telemetry.jsonl. The digest already gave me latency means. What I need is prompt anatomy. decisions.jsonl is the only place. Read offset 0, 24KB.
Let me also reconsider: is there any chance the 16k tokens is because BOTH players' calls are logged... no, 184 decisions total across both players, 2.98M tokens_in total. Per call 16k. Yeah.
Alternatively the football_v2 prompt template itself is huge (league-fixed). If so, can I pass a different prompt? cfg.get("prompt", "football_v2") — the factory accepts a `prompt` param. Maybe it accepts a custom STRING (not just a template name)? If prompt="football_v2" is a template name, maybe I can pass my own minimal prompt text! The reference team would show usage... which I couldn't read (FileNotFoundError). Hmm, maybe try reading reference/club/team.py once more? The earlier failure might've been transient. But that's another turn.
Plan: Turn A: read decisions.jsonl offset 0. This is the highest-information read available. From the record structure I'll likely see the prompt text (or at least obs structure), and can decide how to cut.
Let me also keep in mind the deadline question — what happens on missed deadline. If the engine drops the action, our players did nothing for 178 decisions — yet we scored 3 and lost 4-3, so actions must eventually apply (or the fallback...). Actually maybe on missed deadline the engine reuses the last action — meaning our robots kept doing stale things. Either way, fixing latency is the fix.
One more consideration for the rewrite — the presser LLM call: even at 2.46s, is it worth it vs pure shell? The shell fallback for presser: kick at goal centre within 1.2m, else go_to_ball. That's... actually pretty good for 2v2. The LLM's value: better kick targets, when to pass to mate, when to hold. But if every LLM decision misses its deadline, its value is ~zero anyway (stale actions). So: throttle LLM calls to moments that matter (in kick range / near opponent), and otherwise run local. Even better: only call LLM when within KICK_RANGE + a bit (say 1.8m) of the ball — that's when target choice matters. When far from ball, go_to_ball locally — no call.
And slim the obs: pass only self, ball, teammates, opponents, goals, score/clock if present. I'll see schema from decisions.jsonl.
Also the "say" — keep shouts for presser from LLM replies; cover robot gets simple local shouts occasionally (e.g., on takeover "Mine!" already local). Fine.
Also: role assignment must happen BEFORE the agent call now. Restructure decide():
1. Parse obs: self state, fallen → hold (no LLM).
2. Ball, mate, assign role.
3. If presser and ball visible and dist to ball <= LLM_RANGE (e.g., 2.0m): call LLM with slimmed obs; validate; fallback to shell presser logic.
4. Else: shell logic (go_to_ball or cover walk). No LLM.
Wait, careful: if presser is far from ball, go_to_ball locally — but then the presser never "thinks" until close. That's fine — chasing a ball needs no thought.
But hmm — one risk: if LLM is only called near the ball, and latency is 2.46s, the robot near the ball acts on stale info... The kick decision inside 1.2m: shell says kick at goal centre. LLM might pick a corner. Marginal gain, big latency cost. Honestly, maybe go FULLY local this session (zero LLM calls in open play) and see practice result? That's a big identity decision — "LLM brain inside positional shell" is our identity, and the league is a benchmark of the model. Playing with zero LLM calls feels like abandoning the benchmark... but the benchmark is the CLUB's performance. Hmm.
But wait — actually there's a strong argument for keeping SOME LLM: the league is a benchmark of frontier models; our shouts and decisions are public. But winning matters most, and 178/184 missed deadlines means the LLM is currently a liability. A middle path: LLM for the presser only, throttled (e.g., at most once per 2s, and only within 2.5m of ball), with slimmed obs to cut latency. If slimming obs gets latency under the deadline, we get the best of both.
I need the deadline value! Maybe it's in the rules doc I read... I recall "missed deadlines" in digest. The rules probably define the decision deadline (e.g., 1.0s). From the condensed log I don't have it. The decisions.jsonl records might include a "deadline_s" or the digest might. I'll look at the record.
OK, executing: Turn A = read decisions.jsonl offset 0. Let me write a brief prose then the JSON.
Actually — also worth considering: maybe check whether there's a "docs/MOTION.md" mention... no, irrelevant to behaviour.
One more thing: the 504 errors are from MY OWN model API (api.aimlapi.com serving me, the gaffer). They cost 120s backoffs each. Nothing I can do about that except be concise. My replies should be SHORT to reduce exposure. Keep prose to 1-2 sentences.
Let me go.
Two gateway timeouts have bled the clock, so from here I'm decisive. The fix I've diagnosed stands regardless of details, but one read of our private decisions log will show me exactly what's fat — the observation schema, the prompt anatomy, whether history accumulates — and that decides how I cut. Slice from the top:

Thought for 2,840 words
Let me take stock. I'm in a session with 10 turns left, $0.30 spent of $2.50, 33 minutes left. I've had three gateway timeouts wasting time.
What I know:
1. My club GLM FC lost 4-3 to Synthetic Athletic in s3 match 3.
2. The digest showed 178/184 missed deadlines, mean latency ~2.46s, ~16k input tokens per call (2.98M tokens / 184 decisions).
3. My team.py: the shell calls `self.agent.decide(obs)` BEFORE checking fallen, and the cover robot's LLM reply is completely ignored (the shell overrides with walk_to cover position). So every cover-role call is wasted tokens AND wasted latency.
4. The decisions.jsonl path failed — it's probably in a different location. The prompt said "your own club's private decisions.jsonl" is in data/. Maybe it's under a different path structure. The error shows it tried 'frontier_glm/seasons/s3/...' — so maybe the private decisions are at data/frontier_glm/... or similar. Actually the error path is '.../runs/gaffer_data/frontier_glm/seasons/s3/m3_synthetic_athletic_frontier_glm/decisions.jsonl' — so the file doesn't exist there. Maybe it's named differently, e.g., 'glm_decisions.jsonl' or in the match dir there's a different name. I could ls the match directory to see what files exist.
But wait — I have 10 turns left. I need to be decisive. The key fix is clear:
**Fix 1 (the big one): Don't call the LLM when the reply won't be used.**
- If fallen → hold, skip LLM call entirely.
- If covering (not presser) → the shell ignores the reply anyway; skip the LLM call entirely (or only call occasionally for shouts?). Actually the cover robot's reply is only used for `say`. The shell completely overrides the action. So calling the LLM for the cover robot is pure waste — half our tokens and latency for nothing.
But wait — there's a subtlety. The role assignment happens AFTER the LLM call in current code. I need to restructure: compute ball, mate, role assignment FIRST (pure Python, no LLM), then only call the LLM if the player is the presser (and not fallen). That cuts LLM calls by ~50%+ and eliminates all the wasted latency on cover decisions.
Actually, hold on. Let me think about whether the cover robot should ever call the LLM. The playbook says "LLM brain inside a positional shell" — the LLM reads the game for the presser. For the cover robot, the shell's positional play is the decision. The LLM's only contribution would be a `say`. Not worth 16k tokens and 2.5s latency. Skip it.
**Fix 2: missed deadlines.** 178/184 missed deadlines at 2.46s latency. The registry says luna is 0.6-0.9s warm. Why 2.46s? Possibly because of 16k input tokens. Where does 16k tokens come from? The observation itself might be huge (detections, telemetry), or the prompt template "football_v2" is fat, or history accumulates inside the agent. I can't easily change the agent factory's internals. But if the obs is huge... the agent factory takes obs as given. Hmm.
Actually — maybe the agent factory maintains conversation history internally (each decide appends obs + reply to the message list). That would explain growing token counts. I can't see the factory code (reference/club/team.py read failed with FileNotFoundError — weird).
Options to cut tokens/latency:
- Call the LLM less often (only for presser) — halves the calls.
- Possibly pass a trimmed obs to the agent? The agent's decide(obs) — I could construct a slimmed obs dict with only the fields needed. If the factory serializes the whole obs into the prompt, slimming it would cut tokens massively. E.g., keep self (field_xy, fallen), you (goals), detections (ball, teammates, opponents maybe), and drop whatever else is in there (maybe full joint states, match state, clock, score...). I don't know the obs schema in detail. From my code I see: obs["self"] with "fallen", "field_xy"; obs["you"] with "defend_goal_xy", "attack_goal_xy"; obs["detections"] with "ball" (field_xy, age_s), "teammates" (field_xy). There may be much more — e.g., "opponents", "match", "clock", "score", "last_events", "shouts"...
Risky to slim blindly — if I drop fields the prompt template needs, the agent might behave worse. But the shell validates everything and falls back to sound shape, so worst case the presser's LLM replies get invalid and we fall back to kick-at-goal/go-to-ball, which is... actually what the fallback does anyway. Hmm, but the LLM's value is choosing kick targets etc.
Actually wait. Let me reconsider. The fallback for presser inside kick range is kick at goal centre; outside, go_to_ball. The LLM presumably adds smarter targets (corners, passes to mate). The playbook lists "Kick targets are always the goal centre" as a gap — meaning currently even the LLM's targets... no wait, that gap note says kick targets are always goal centre — that's the fallback. The LLM may pass to mate etc.
Given 10 turns and ~33 min, I should:
1. Restructure decide(): role assignment first, LLM only for presser and only when not fallen. (Big win: halves calls, removes all cover latency.)
2. Maybe slim the obs passed to the agent — but I don't know the schema well. Risky without seeing the decisions log or the factory.
Actually, can I find the decisions.jsonl? The prompt says "your own club's private decisions.jsonl" is in data/. The failed path was data/seasons/s3/m3_.../decisions.jsonl. Maybe it's at data/decisions/... or data/private/... Let me ls data/ to find it. That's one turn. It would tell me the prompt anatomy (what makes 16k tokens). That's valuable — but is it worth a turn? I have 10 turns. The main fix doesn't depend on it. But knowing whether the bloat is obs-size vs history accumulation decides whether slimming obs helps.
Hmm, actually there's a smarter move: `practice` after the fix will show me the new latency/token numbers in... wait, practice returns score and event tape. Does it return digest-like numbers? "returns the score and event tape". Maybe not latency. But my own practice matches write states.npz etc. Not obviously a digest. Hmm.
Let me think about what the 16k tokens could be. 184 decisions, 2.98M tokens_in → 16.2k per call. If the prompt template "football_v2" is a fixed league blob, it might be a few k. The obs serialized might be a few k. History accumulation would grow over the match — the average would be less than the final. 16k average suggests either a fat fixed prompt or heavy per-call obs.
Actually — one more possibility: the agent factory might include the full rules/doc in the system prompt. I can't change that. What I CAN change:
- How often we call (halve it).
- What obs we pass (slim it).
Also — maybe I can pass a custom prompt string instead of "football_v2"? `make_football_agent(model, idx, seed, prompt=...)` — prompt defaults to cfg "football_v2". If prompt accepts an arbitrary string (a custom system prompt), I could write a tight, small prompt myself! The reference team's PROMPTS.md (which I couldn't read) presumably documents prompt templates. The parameter is `prompt=roster[k].get("prompt", cfg.get("prompt", "football_v2"))` — it takes from team.yaml config. So I could set `prompt:` in team.yaml to a custom short prompt string. But is `prompt` a template NAME or free text? Unknown. If it's a name of a league-provided template, a custom string might fail or be ignored. Risky.
Given uncertainty, the safest high-value changes:
1. Role-first restructure; LLM only for presser, never when fallen. This alone should cut missed deadlines massively (cover decisions become instant, ~half of all decisions) and halve token spend.
2. Keep everything else the same.
Then practice once to verify it loads and plays soundly, lint, note, done.
Actually wait — there's a risk with skipping the LLM for the cover robot: the presser role flips between players. When a player becomes presser, it starts calling the LLM. Fine. When fallen, hold without LLM. Fine.
But also: should the presser call the LLM every decision tick? Decisions come at some rate — opponents made 255+ decisions in a match at 1.5s latency... wait, that means flash-lite made 255 decisions with mean latency 1.5s? And missed ~2%? Hmm, if decisions are spaced ~2s apart and latency is 1.5s, they make it. Our 2.46s missed 97%. So the decision deadline is probably ~2s. If I only call for the presser, the presser still might miss deadlines at 2.46s latency! The presser's decisions would still be late ~97% of the time. What happens on a missed deadline — the engine uses the last action? Or holds? Missed deadlines probably mean the robot keeps executing the previous command (or holds). For a presser chasing a ball, a stale go_to_ball is mostly fine; a stale kick_toward is fine too. But it hurts reactivity.
So halving calls helps cost and cover-reactivity, but the presser's latency problem remains if the model genuinely takes 2.46s on 16k tokens. Cutting input tokens is the real latency fix. Where do the tokens come from? I need the decisions log. Let me spend ONE turn finding it: ls data/ (and maybe the match dir) to locate decisions.jsonl.
Actually the system prompt says: "data/ the league archive: results, tables, every match's public logs (match.json, comms.jsonl, telemetry.jsonl), the rules (data/RFL_RULES.md), the model registry, and your own club's private decisions.jsonl." So decisions.jsonl exists somewhere in data/. The match dir listing earlier (from condensed session) — I read digest.json at data/seasons/s3/m3_synthetic_athletic_frontier_glm/digest.json successfully. The decisions.jsonl is NOT in the match dir (FileNotFoundError). Maybe it's at data/decisions/s3/m3_.../decisions.jsonl or data/private/... Let me ls data/seasons/s3/m3_synthetic_athletic_frontier_glm/ to see what IS there, and/or ls data/.
One ls of the match dir shows what's beside digest; but decisions.jsonl might live under a club-specific private folder. `ls data/` first — top level will show the structure. That's the best single turn.
Hmm, but with 10 turns left, let me budget:
- Turn 1 (now): ls data/ to find decisions.jsonl location.
- Turn 2: read a slice of decisions.jsonl (first decision record shows the prompt anatomy).
- Turn 3: write the new team.py (restructured, plus obs-slimming if warranted).
- Turn 4: lint.
- Turn 5: practice 90s.
- Turn 6: maybe fix something / practice 2.
- Turn 7: lint again if changed.
- Turn 8: note in NOTES.md.
- Turn 9: done.
That fits. But gateway timeouts keep eating turns (3 so far, each with 120s backoff). The clock says 33m left. Each timeout costs 2+ minutes. I should front-load the critical work: write the code change EARLY, then verify. Actually the most important thing is a committed improvement. The restructure alone is a clear win regardless of what the decisions log shows. The obs-slimming is the part that depends on the log.
Alternative plan: skip the log hunt, write the restructured team.py now (with a modest, safe obs-slim: pass through only the keys my code and a football prompt plausibly need — actually no, don't guess). Hmm.
Let me think about what's in obs. From the reference implementation (which I couldn't read — FileNotFoundError, weird) and my own code, obs has: "self" (field_xy, fallen, maybe more), "you" (defend_goal_xy, attack_goal_xy, maybe score), "detections" (ball, teammates, opponents?), maybe "match" (clock, score), "shouts"/"comms" (recent public shouts). The engine docs (docs/MOTION.md in the engine repo) — not available here. RFL_RULES.md I read up to 22192 chars (it said offset 24000 past end; I read the first 24k which covered... I don't remember details, condensed).
Honestly, the safest obs handling: pass obs through unchanged to the agent (the factory knows its contract), but only call it for the presser. If the decisions log shows the prompt is mostly a fixed blob + obs, and obs is huge, then slimming helps; if it's history accumulation, slimming obs helps a bit each turn but history dominates — then maybe I should recreate the agent periodically? No — begin_episode resets it presumably. If history accumulates within the episode, token count grows over the match; average 16k with, say, 92 decisions per player... if each turn appends ~1k tokens of obs+reply, by turn 90 that's 90k. Average would be ~45k. We see 16k average, so maybe history is capped or it's not simple accumulation. Or decisions per player: 94+90=184 total, ~92 each. If prompt is fixed 3k + obs 1k + history capped at last N...
I can't resolve this without the log. ONE ls to find it. If found, ONE read of the first record (offset 0, 24KB — the first record alone might be big; the read tool serves 24KB which might be part of one record. Fine — I'll see the prompt anatomy).
Actually, wait. Let me reconsider the value. Even if I learn the prompt anatomy, what can I DO about it?
- If obs is fat: slim the obs dict I pass to agent.decide(). Doable, safe-ish (shell validates replies; worst case fallback).
- If fixed prompt blob is fat: try passing a custom prompt string to make_football_agent. If the factory accepts arbitrary strings as system prompt, a 300-token prompt would slash latency. If it only accepts template names, my string might break the agent → all replies invalid → shell fallback (kick at goal centre / go_to_ball). That fallback is... actually decent but loses LLM cleverness. Risky but testable in practice! Practice shows the score vs mirror. Hmm, but a mirror match doesn't tell me if the LLM replies are valid. The event tape might show shouts — if shouts appear, the LLM is replying.
- If history accumulates: I could recreate the agent every N decisions (agent = make_football_agent(...)) to reset history. That's within my power in the shell! E.g., every 20 decisions, rebuild. But begin_episode might be needed... I can call begin_episode on the new agent. This is a legit fix if history is the issue.
So the log read genuinely changes what I do. Worth 2 turns (ls + read). Let me do it.
Actually, can I do ls with a path? {"tool":"ls"} listed club/ earlier... The first ls was {"tool": "ls"} → "club/". Hmm, that output was just "club/". Maybe ls takes a path param. The schema shows {"tool": "ls"} without path in examples, but earlier I did [ls] club/ — ambiguous. Let me try {"tool": "ls", "path": "data/seasons/s3/m3_synthetic_athletic_frontier_glm"} to see the match dir contents. If decisions.jsonl isn't there, next try data/ top-level... that's 2 turns potentially.
Alternatively {"tool": "ls", "path": "data"} shows top-level structure including any private dir. That's the better single probe: it reveals where private decisions live (e.g., data/private/ or data/frontier_glm/). Hmm, but it might not recurse.
Let me just do ls data/ and see. Actually — wait. Maybe I should reconsider: is the decisions log even worth it when I could instead look at comms.jsonl (public shouts) — no, that doesn't show prompts.
Decision: this turn, ls data/ (with path param). Brief prose first.
Actually, hold on — let me also reconsider the biggest possible win once more. The digest: 184 decisions total for BOTH players across the whole match?? A match is ~2 halves... how long? If decisions are every ~2s and a match is 4 minutes of play... 184 decisions/2 players = 92 each ≈ one decision per 2.6s per player over 4 min. OK so decision cadence ~2-2.5s, deadline probably 2s. Opponents: 255+ decisions at 1.5s mean latency, ~2% missed. So flash-lite at 1.5s makes ~2s deadlines. Our 2.46s misses ~97%.
If I halve calls (presser only), the presser still misses ~97% of ITS deadlines. What does a missed deadline do? Probably the engine reuses the last valid action or the player holds. If it holds — disaster for pressing. If it reuses last action — mostly OK for chasing. The digest counts "missed-deadlines" as a stat, and the league tracks it, so it matters. To actually fix the presser's latency I must cut input tokens.
Also — maybe reduce call frequency for the presser too? E.g., only re-consult the LLM every other decision or when the situation changed (ball moved >1m, or every 2 decisions). Between consults, reuse the last validated reply or recompute shell fallback. That reduces average latency impact AND cost. But it also slows reactions. Hmm — with 2.46s latency, the reply is already stale when it arrives. Reusing a 2s-old reply vs computing a fresh shell action... The shell fallback (go_to_ball / kick at goal) is computed fresh each tick with zero latency. Honestly, for the presser, fresh shell actions might beat stale LLM replies! The LLM's edge is target selection (pass to mate, shoot corners).
A hybrid: presser uses LLM reply when fresh (<1 decision old), else shell fallback. And call the LLM at most every other tick. This caps token spend and keeps reactivity.
But careful: I shouldn't over-engineer with 10 turns left and flaky gateways. Priorities:
1. Restructure: role-first, no LLM when fallen or covering. (Certain win: cost, cover latency.)
2. Find and cut the token bloat if cheaply possible. (Log-informed.)
3. Lint, practice, commit.
Let me go. This turn: ls data/ to locate the private decisions log.
Prose: brief — the decisions.jsonl isn't in the match dir; need to find where the private log lives because its first record shows the prompt anatomy (fixed blob vs fat obs vs history), which decides how I cut the 16k tokens/call.
JSON: {"tool": "ls", "path": "data"}
The private decisions log isn't inside the match directory, so before writing code I need one look at it: the first record will show whether our 16k tokens per call come from a fat fixed prompt, a fat observation, or history accumulating inside the agent — and that decides whether the fix is slimming the obs, a custom prompt, or resetting the agent. Locating it first.

Thought for 2,673 words
Let me think about where I am. I've spent $0.33 of $2.50, 27 minutes left, 9 turns left. I've had three 504 timeouts bleeding the clock.
Key facts established:
1. Match 3 digest: 178/184 missed deadlines, ~2.46s mean latency, ~16k input tokens per call (2.98M tokens / 184 decisions).
2. My code: `decide()` calls the LLM agent BEFORE checking `fallen`, and the cover robot's LLM reply is completely ignored — every cover-role model call is burned tokens for nothing.
3. The decisions.jsonl is at `data/private/s3/m3_synthetic_athletic_frontier_glm/decisions.jsonl` (1089 KB).
With 9 turns left, I need to be decisive. The plan:
1. Maybe one quick slice of decisions.jsonl to confirm the prompt anatomy (1 turn). Actually — do I need it? The diagnosis is solid: 16k tokens per call. The fix regardless: skip the LLM call when fallen, skip the LLM call when in cover role (or at least when the reply is ignored). That alone cuts model calls roughly in half or more (cover role is ~half the time for each robot, plus fallen time).
But wait — is cutting the cover robot's LLM call entirely the right football move? The cover robot's reply is ignored by the shell anyway, so the call produces nothing except latency and cost. Removing it is pure win: no behavior change, half the calls, half the token spend, and crucially the presser's calls might get... no, the presser's calls are independent. But missed deadlines: if the deadline is per-decision, then the cover robot currently misses its deadline because the LLM takes 2.46s. If we skip the LLM for cover, the cover robot responds instantly (shell computes walk_to target) — 0 missed deadlines for cover decisions. The presser still calls the LLM.
Actually, what is the deadline? Probably something like 1.5-2s per decide() call. The presser's LLM call at 2.46s would still miss. Hmm. But maybe the 2.46s mean latency is inflated by the fat prompt; if the prompt is 16k tokens because of accumulated history inside the agent, then... I can't reset the agent's history without knowing the SDK.
Options to reduce presser latency:
- The prompt param: `prompt=roster[k].get("prompt", cfg.get("prompt", "football_v2"))` — the default is "football_v2", a named league prompt. Maybe there are other named prompts (football_v1?) that are smaller. I don't know without docs. The rules doc was truncated at 22192 chars and I read the first 24KB... actually I read data/RFL_RULES.md and it got truncated at 24000? No — the read said 22192 chars total, and my offset 24000 was past the end. So I read the whole thing? The first read returned 24KB starting at 0, and the file is 22192 chars, so I saw it all. But the condensed log says "The rules doc was truncated right where the SDK and agent-factory contracts probably live" — hmm, that suggests the read was truncated at 24KB but the file is 22192 chars so it wasn't. Actually the log says I read it and then tried offset 24000 which was past the end. So I saw the whole rules doc. But I don't remember its contents now (condensed). The key question: does make_football_agent accept a custom prompt string, or only named prompts? And is there a way to limit history?
With 9 turns left, I can't afford much more reading. Let me prioritize:
Turn plan (9 turns):
1. Slice decisions.jsonl at a good offset to see one record's anatomy (prompt/messages structure). This tells me if history accumulates. (1 turn)
2. Write the new team.py with the fixes. (1 turn)
3. Lint. (1 turn)
4. Practice (90s) to verify. (1 turn)
5. Maybe practice again or adjust. (1-2 turns)
6. Note in NOTES.md. (1 turn)
7. Done. (1 turn)
That's 7-8 turns. Tight but feasible. The 504s are eating turns too — each model error costs a turn? Actually the model errors appear as harness messages after my turn; the "backing off 120s" suggests the harness retries. The turns counter says 9 of 28 left — I've used 19 turns already, many to timeouts.
Actually, let me reconsider: do I even need to read decisions.jsonl? The fix I'm confident about:
1. Check `fallen` BEFORE calling the agent — pure win.
2. Don't call the agent when the shell will ignore its reply (cover role, ball lost) — pure win, halves calls.
3. For the presser: the LLM call still takes 2.46s and misses deadlines. Can I make the presser faster? Options:
a. Only call the LLM every N decisions (e.g., every 2nd or 3rd), caching the last valid reply and re-validating targets. Between calls, use the shell fallback (go_to_ball / kick at goal). This halves or thirds the presser's calls AND means most decisions return instantly. The cached reply can be re-used if still valid.
b. Slim the prompt — unknown API, risky.
Option (a) is powerful: call the LLM at most every ~1.5-2s (or every k-th decide), and otherwise act from cache/shell. But careful: if decide() is called at some Hz (maybe 2-5 Hz?), and the deadline is per-call... If I skip the call, I return instantly. The LLM call happens asynchronously? No — it's synchronous; the 2.46s latency means the decision arrives 2.46s late, missing the deadline. If I only call on every 3rd decision, then 2/3 of decisions are instant (shell), and 1/3 still miss. Missed deadlines might still be ~1/3 of presser decisions instead of ~97%.
Hmm, but what does "missed deadline" actually cost? Probably the action is applied late or dropped. If the engine drops late replies, then the presser's LLM replies NEVER get applied — 178/184 missed means almost every LLM-influenced decision was dropped, and we were effectively playing pure shell football! That explains why we still scored 3 and lost 4-3: the shell is decent.
So the real fix: make decisions arrive within the deadline. Two levers: fewer/cheaper calls (skip when unused) and caching with periodic refresh.
Actually, wait. Let me think about what the deadline likely is. Registry says luna warm latency 0.6-0.9s. Opponents (flash-lite) at 1.5s missed ~2%. So the deadline is probably ~1.5-2s. Our 2.46s mean misses. If the prompt were smaller, luna might hit 0.9-1.2s and make it. The 16k tokens per call — where from? The observation itself might be big (detections with ages, teammates, opponents, ball trajectory history?). Or the agent keeps conversation history. If the agent accumulates history, calls get slower as the match progresses — I could check latency growth over the match in the digest... the digest has mean latency; the decisions.jsonl has per-decision records.
A quick slice of decisions.jsonl would show: the messages array (system prompt + user content), whether history grows, and per-call latency. That's valuable for choosing between "cache every N" vs "reset agent". One read at a chosen offset. The file is 1089KB, ~184 decisions for us... wait, decisions.jsonl includes all four players? It's OUR private decisions log — probably only our two players, 184 records, ~5.9KB per record. Reading from offset 0 gives the first record(s) — early match. To see history growth I'd want a late record — offset ~1000000. But each read is 24KB, so I'd see ~4 records per read. Two reads (early + late) = 2 turns. That's affordable if I'm decisive elsewhere.
Actually, maybe just one read in the middle-to-late portion. If records show a "messages" list with growing history, that's the smoking gun. If they show a fixed system prompt + one user message with a huge observation, then the obs is fat and I can't change it (obs comes from the engine)... but I CAN pre-filter the obs before passing to the agent! The shell receives obs and passes it to agent.decide(obs). I could strip fat fields (e.g., trim detections to essentials) before the agent call. That's within my control!
That's a big insight: I control what obs I pass to the agent. If the obs is 10k tokens of detection history, I can slim it to the essentials: self state, ball, teammates, opponents, goals. The agent only needs enough to decide.
So reading one decisions record is definitely worth 1 turn to know the anatomy. Let me do offset ~500000 (mid-match) to see both structure and whether it grew. Actually early vs late comparison needs 2 reads. Hmm. Alternatively the record might include token counts per call — the digest had tokens_in total. If each record has tokens_in, one mid-match read shows whether a single call is ~16k.
Let me plan the code changes now (so the write turn is ready):
```python
def decide(self, obs):
self_state = obs.get("self") or {}
if self_state.get("fallen"):
return {"skill": "hold"}
# compute ball, mate, roles first (cheap, no LLM)
...
if presser == self.shirt and ball is not None:
# maybe call LLM, with throttle
if self._due_for_llm():
reply = call agent
cache it
out = valid(cached) or shell fallback
else:
# cover: no LLM at all
out = walk_to cover target
```
Throttling: track time. Do I have a clock in obs? There might be a match time in obs (e.g., obs["t"] or self_state["time_s"]). If not, count decisions: call LLM every 3rd presser decision. But if decide is called at 2Hz, every 3rd = 1.5s between calls — the presser would act on stale/shell decisions between. The shell fallback for presser is decent (go_to_ball, kick at goal inside 1.2m). Actually for the presser, the shell fallback IS the main behavior; the LLM adds nuance (pass targets, angles). Given 97% of LLM replies were dropped anyway, the shell is what we've been playing. Making 100% of decisions arrive on time (shell) with occasional LLM refresh (if it arrives in time, great) is strictly better than now.
Wait, actually — if the reply misses the deadline, is it dropped, or applied late? "missed deadlines" in digest. If applied late, the LLM still influences play, just laggy. Either way, cutting latency helps.
Also: should the cover robot ever call the LLM? Currently its reply is discarded. I could give the cover robot's LLM reply some use (e.g., let it choose to intercept), but that's a football improvement for later. For now: no LLM for cover. Halves our token spend and cost.
Also the "say" shouts: currently say comes from the reply. If we skip LLM calls, we lose shouts. Shouts are public/branding. I can add simple deterministic shouts ("Mine!" on takeover — already there). Fine.
Another consideration: `begin_episode` — fine as is.
What about the agent's internal history? If make_football_agent's agent accumulates messages, throttling calls also slows history growth. Good.
Now, the prompt param: "football_v2" named prompt. Maybe there's a "football_v1" or a "brief" variant. Without docs I shouldn't guess. The rules doc — I read it fully but don't recall. Risky to change.
One more idea: pass a slimmer obs to the agent. If the obs includes e.g. "detections" with lots of fields, I could construct a minimal obs dict: {"self": {...}, "detections": {"ball": ..., "teammates": [...], "opponents": [...]}, "you": {...}}. But I don't know the exact schema the agent's prompt builder expects — if it expects a field I strip, it might crash (caught by try/except → empty reply → shell fallback; safe). The agent is the league's factory; it presumably formats obs into the prompt. Slimming obs reduces tokens if the obs is the fat part.
I need the decisions.jsonl read to decide. Let me do it: one read, mid-file, offset ~540000 (half of 1089KB). Records are JSON lines; a read starting mid-line will show a partial line then full ones. Fine.
Actually — better: the digest said tokens_in ~2.98M for 184 decisions ≈ 16.2k per decision. If the system prompt were the fat fixed part, every club using the default prompt would suffer equally — but Synthetic Athletic's flash-lite players made 255 decisions at 1.5s. Different model, but if the prompt were 16k tokens for everyone, flash-lite would also be slower. 1.5s for flash-lite suggests their per-call input is much smaller OR flash-lite is just faster per token. Hmm, flash-lite at 1.5s vs luna at 2.46s — luna is supposed to be the "fast tier" at 0.6-0.9s warm. So our 16k tokens is NOT the league default experience; something in OUR usage is fat. What could make OUR calls fatter than the default? The obs we pass is engine-standard... unless the agent accumulates history (each call appends the previous obs+reply). Synthetic Athletic might use a different agent setup (maybe they call the LLM less often, or they reset, or their club code strips obs).
The decisions.jsonl will show the actual messages. Let me read it. Offset: let's aim for late-match to see max history growth: offset ~900000. If records there show huge message arrays vs early ones, history accumulation confirmed. But without the early read I can't compare... The record itself might include a token count or the messages array length is visible. If I see a messages array with 50+ entries, that's accumulation, no comparison needed.
Let me do offset 900000, one read. Then decide and write.
Plan for remaining 9 turns:
1. (this turn) read decisions.jsonl @ ~900000 — see anatomy.
2. write new team.py (skip LLM when fallen/cover; throttle presser LLM to every N decisions or by time; slim obs if that's the fat; keep shell identical otherwise).
3. lint.
4. practice 90s.
5. (if needed) fix + lint.
6. note NOTES.md + maybe PLAYBOOK tweak.
7. done.
That leaves buffer for one 504 or one extra fix. Good.
Actually, also consider: maybe I should check whether obs has a time field for throttling. I'll write the code defensively: use decision-count throttling (every 3rd presser decision) AND try obs clock if present. Simple: count-based. If decide() is called at ~1-2Hz per player... 184 decisions over a match (~how long? matches are 2 halves; telemetry 73KB; probably 2×90s or 2×120s = 180-240s). 184 decisions / 240s ≈ 0.77 Hz per... wait 184 is both players combined (Zhi 94, Pu 90). So ~0.8 Hz per player. Hmm, that's roughly one decision per 1.3s. If the deadline is ~1.5s and mean latency 2.46s, most miss. If I throttle to every 3rd presser decision, LLM calls drop to ~0.15 Hz per player; between them, instant shell decisions. But each LLM call still takes 2.46s — during which... does decide() block the simulation? If the engine calls decide() synchronously and waits, the robot stands still for 2.46s! That would be terrible — the robot freezes every decision. Actually missed deadlines suggest the engine has a deadline mechanism: maybe it runs decide() async with a timeout, and if the reply is late it uses the last/fallback action. I can't know exactly. Either way, fewer calls = fewer freezes/misses.
Alternatively — maybe I should drop the LLM presser call entirely this session (pure shell football, zero missed deadlines, zero player-model spend) and reintroduce a throttled LLM once I've confirmed the deadline mechanics? The playbook says the LLM brain is our identity... but pragmatically, 178/184 missed means the LLM contributed almost nothing anyway. A throttled call (every 3rd) keeps some LLM flavor at 1/3 the cost. Hmm, but each call still risks a 2.46s stall for the presser.
Let me look at the decisions.jsonl first — if it shows the messages anatomy, I may find the real fix (e.g., history accumulation → the agent might have a reset/limit; or fat obs → slim it, cutting latency to ~1s, making deadlines).
OK, writing this turn: brief prose + read decisions.jsonl at offset ~900000. Actually, hmm, mid-file might catch a mix. Late file shows worst case. Let me pick offset 950000 (of 1089KB) — near the end, second half action.
One more thing: the digest for match 3 — I should double check per-player latency... I already have: Zhi 90/94 missed, Pu 88/90, mean ~2.46s. Good enough.
Let me also keep in mind the s0 match (m2 vs real_machina) — our earlier match; decisions.jsonl exists for it too (1074KB). Not needed now.
Prose: brief — found the private log at data/private/, reading a late slice to see the prompt anatomy (fixed blob vs growing history), then I write the fix.
Found it — the private log lives under `data/private/s3/...`, not in the match directory. One slice near the end of the file will show me the anatomy of a late-match call: whether our ~16k input tokens are a fixed fat prompt, a fat observation, or history accumulating inside the agent as the match runs. That single fact decides the fix, and I still have the turns to write it.

Thought for 3,125 words
Let me take stock. I'm in a session with 7 turns left, $0.36 spent of $2.50, 15 minutes of clock left. The session has been plagued by 504 gateway timeouts.
What I know:
1. My club GLM FC lost 4-3 to Synthetic Athletic in s3 m3.
2. The digest showed 178/184 missed deadlines, mean latency ~2.46s, ~16k input tokens per call.
3. My team.py code: GLMPlayer wraps an agent from make_football_agent. The decide() calls the LLM agent before checking fallen, and the cover robot's LLM reply is completely ignored by the shell — burned tokens for nothing.
4. The decisions.jsonl slice I read was actually from Synthetic Athletic's robots (robot 0/1, team "Synthetic Athletic") — wait, no. The private decisions log is MY club's private decisions... Actually looking at the records: `"team": "Synthetic Athletic"` — hmm, that's odd. The file is data/private/s3/m3_synthetic_athletic_frontier_glm/decisions.jsonl. It says robot 0, team "Synthetic Athletic". Wait — maybe the private folder logs both teams' decisions? Or maybe the "you" team field is mislabeled. Actually the obs shows "attack_goal_xy": [7.0, 0.0], "defend_goal_xy": [7.0, 0.0] — both the same, which is weird. And latency_s values of 1.265, 2.23, 1.027 with status "ok" — these look like Synthetic Athletic's decisions (they had ~1.5s latency, ~2% missed). So the private decisions.jsonl might contain both teams or just... hmm. Actually wait — the digest said MY players (Zhi 90/94, Pu 88/90 missed deadlines). The records I read show status "ok" with latency ~1-2s. The team field says "Synthetic Athletic". So this slice shows the opponent's decisions. The file may interleave both teams' decisions, or it's sorted somehow. Either way, the observation format is what matters: each decision record has a full obs with detections, field, referee, camera note, etc. That's maybe 1-2k tokens of JSON per call, not 16k. So the 16k input tokens per call must come from the prompt template ("football_v2") plus the obs... or the agent accumulates history.
Actually, I computed ~16k tokens per call from 2.98M tokens / 184 decisions. But wait — that tokens_in might include the opponent's too? No, the digest was for my club. Hmm, but if the private decisions.jsonl contains both teams... the digest per-player numbers were for my players.
Key insight regardless: the observation itself is ~1.5-2k tokens of JSON. The prompt template "football_v2" is the league's standard prompt — probably a few thousand tokens. The camera note says "raw frames also attached (_frames)" — 2 frames attached! If the agent is a vision model receiving 2 camera frames per call, that's where the tokens/latency go. But I can't change what the agent factory attaches... or can I? The prompt parameter is roster[k].get("prompt", cfg.get("prompt", "football_v2")) — so I can pass a custom prompt string instead of "football_v2".
I don't have time to fully explore the SDK docs. With 7 turns and 15 minutes left, I need to make the decisive changes NOW:
1. **Don't call the LLM when fallen** — check fallen first, return hold immediately. Saves wasted calls.
2. **Don't call the LLM for the cover robot** — the shell ignores its reply anyway. Instead, compute the cover position directly and emit walk_to. This halves our model calls (and halves our token spend and missed deadlines).
3. **Only call the LLM for the presser when it matters** — e.g., when within kicking distance or when the ball is close; otherwise go_to_ball directly. Actually, the presser's LLM reply IS used. But we could gate: if ball not seen or far, just go_to_ball without calling. Hmm, but the LM might add value in choosing kick targets. The biggest win: cover robot never calls the LLM. Presser calls only when ball is seen and within some distance, else go_to_ball.
Actually wait — let me reconsider. The missed deadlines mean the decision was DISCARDED — the robot kept doing its last skill. So a missed deadline isn't catastrophic, but it means we're effectively running open-loop. The fix: fewer, cheaper calls that fit in the deadline.
Also the shout: the shell probably passes a shout. Let me recall the code... I read team.py earlier (condensed). From what I remember of the structure: GLMPlayer.decide(obs) — checks role via _role(), if presser: calls self.agent(obs) or similar, validates reply, applies; if cover: computes cover target and... actually the session log says "the cover robot's LLM reply is completely ignored by the shell — every cover-role model call is burned tokens for nothing". So the code calls the agent for both, but only uses the presser's reply.
I don't have the full current team.py text in front of me (the earlier reads are condensed). I read it twice but the content is condensed in the log. I know the tail (from offset 4400): _role logic, _valid, build_team. I need to see the first 4400 chars to rewrite decide() properly. That's one read (24KB limit, file is 6.6KB total — one read gets it all).
Plan for remaining 7 turns:
1. Read club/team.py (full, 6.6KB — one turn).
2. Write the new team.py with the fixes (one turn).
3. lint (one turn).
4. Maybe practice (one turn) — but practice costs budget and time; with 15 min left and 504s happening, practice (90s) is risky but valuable. Practice spends player-model call money from session budget. Given the whole point is latency/deadlines, a practice match would verify. But if 504s hit during practice... practice is run by the harness, not my API, so it should be fine.
5. note in NOTES.md (one turn).
6. done (one turn).
That's 6 turns of 7. Tight but feasible. Actually I should combine: write NOTES.md update via note tool, then done.
Let me be careful about what the new team.py looks like. I need to see the current one first to preserve the shell logic (role assignment, cover position computation, shout handling, ball memory). Let me read it now.
Actually — one consideration: should I read team.py first or just write from scratch? I know the architecture well from the tail and my earlier reads, but the details of decide(), the shout mechanism, _clamp, ball memory (3s), wall margins — I need the exact code to keep the good parts. Read first. It's 6618 chars, one read.
Then the rewrite:
```python
def decide(self, obs):
# Fallen: no LLM call, hold immediately.
self_state = obs.get("self") or {}
if self_state.get("fallen"):
return {"skill": "hold", "shout": "up"}
...
```
Wait — what's the exact return contract? The decisions.jsonl shows "applied": {"skill": "go_to_ball", "target": null, "lead_s": 0.0}. And _valid returns {"skill": ..., "target": ...}. The reply may include "shout" — player shouts are natural language and public. The current code probably passes shout through. I'll see when I read.
Key changes to make:
1. Fallen check BEFORE any agent call → return hold.
2. Cover role: NO agent call. Compute cover target (ball→own-goal line, 2m goal-side), return walk_to with that target. Maybe add interception: if ball is moving toward our half and cover can reach it first... keep it simple — the playbook says one change per session, but these are all one disease: wasted/slow model calls. The theme: "spend model calls only where they change the outcome."
3. Presser role: call the agent ONLY when the ball is seen and within, say, 3.5m (where kick/angle decisions matter); otherwise return go_to_ball directly without a call. Hmm — but go_to_ball with the engine handles pursuit. When ball not seen for >3s (memory), hold shape.
4. Keep the shout mechanism for the presser; cover robot can emit a simple shout without a model call? Shouts come from the model reply usually. Keep it minimal.
Also: the prompt. cfg.get("prompt", "football_v2") — the default prompt template. I could pass a shorter custom prompt. But I don't know the template format the SDK expects (it might be a template NAME, not free text — "football_v2" looks like a named template). Passing a custom string might break it or might be supported. Risky without docs. The safer token cut: fewer calls (cover never calls, presser only calls when close, fallen never calls). That alone cuts calls by maybe 60-70%.
Actually, let me think about the numbers: 184 decisions total for my team in the match (Zhi 94 + Pu 90). If cover-role calls (~half) are eliminated and presser only calls when ball within 3.5m... The presser is usually near the ball by definition (nearest robot presses). Hmm, the presser role is assigned by proximity, so the presser is often close to the ball. But "close" in the sense of within 3.5m? The presser chases; when far from ball, go_to_ball is obviously right — no need for the LLM. When within ~1.5-2m, kick direction matters — LLM adds value. So gate: call LLM only when ball seen and distance < 2.5m, or when a shot/pass decision is live. Otherwise go_to_ball.
Also decision_interval_s was ~2.0-2.3s in the log. Our latency 2.46s mean — just over. Cutting input tokens (if the obs is what's fat) helps; but the obs is fixed by the engine... wait, is it? The obs comes from the engine — I can't slim it. The prompt template — maybe. The camera frames — "raw frames also attached (_frames) if you prefer your own vision" — the agent factory might attach frames by default! If make_football_agent has a parameter to disable vision frames, that would be the single biggest latency cut. I don't know the signature. The rules doc (RFL_RULES.md, 22KB) probably documents make_football_agent. I read part of it earlier but it got truncated at 22192 chars... I read from 0 and it truncated at 24KB? No — read serves 24KB at a time and the file is 22KB, so one read got it all, but my earlier read was condensed in the log. I don't remember the factory signature details.
With 7 turns left, I can't afford to re-read the rules doc (1 turn) AND team.py (1 turn) AND write AND lint AND practice AND note AND done. That's 7 exactly. Risky — any 504 wastes a turn (actually 504s seem to consume turns/backoff but the harness retries... the "model error (1/3)" suggests retries with backoff that don't consume my turn budget? The turns counter said 7 of 28 left after those. The 504s happened mid-session and turns went from 30 to 7 — hmm, that's a lot consumed. Actually the condensed log says 30 earlier entries. The 504 backoffs seem to have eaten turns/clock. The clock is at 15m04s of 1h30m — so most of the clock is gone, largely to backoffs.)
Given 15 minutes of clock: every turn costs clock time (my thinking + API latency). Practice costs 90s+ of clock. I must be brutal:
Turn 1 (now): read club/team.py — full file, need exact code.
Turn 2: write new team.py.
Turn 3: lint.
Turn 4: practice 90s (verify no crash, see latency improvement). — optional if clock tight.
Turn 5: note.
Turn 6: done.
Skip re-reading rules. The factory signature I already use: make_football_agent(model, shirt, seed=..., prompt=...). I'll keep exactly that call — no new parameters I'm unsure about. The fix is purely in MY wrapper logic: when to call the agent at all.
One more thing: the "prompt" — roster[k].get("prompt", cfg.get("prompt", "football_v2")). team.yaml has no prompt key, so it uses "football_v2" named template. Leave as is.
Let me also reconsider: is the cover-robot-LLM-call really wasted? From my earlier analysis (condensed but stated): "the cover robot's LLM reply is completely ignored by the shell — every cover-role model call is burned tokens for nothing." I trust my earlier self's reading of the code. The cover robot's applied action is computed by the shell (walk to cover position), and the LLM reply is discarded. So yes — pure waste. Eliminating it: half the calls gone, half the missed deadlines gone, and the cover robot's actions become INSTANT (no latency) — it will hold shape crisply.
And the presser gating: when ball unseen or far, go_to_ball is the only sane skill; skip the call. When close (< ~2.5m) or when we have a shot angle question, call the LLM for kick target choice. Also when the ball is in our defensive third maybe? Keep simple: call when ball seen and dist < 2.5m. Hmm, but there's also value in LLM choosing walk_to targets for positioning... The shell already handles positioning. Keep the gate.
Wait, actually — I should double check one thing in the code: does the shell use the presser's LLM reply directly, or does it also override? From the playbook: "the shell validates every reply and falls back to sound shape (press / kick at goal inside 1.2 m; cover otherwise)". So presser's validated reply is applied. Good.
Also the shout: public voice. The reply might include a shout field. I'll preserve whatever the current code does for shouts — pass through from reply if present; for non-LLM paths, maybe a canned short shout occasionally? Keep minimal: no shout on fallback paths (or a rare one). Actually shouts are fun for the broadcast but cost nothing extra if part of the reply. The _valid function only passes skill/target — it DROPS shout? That means our players never shout? The comms.jsonl for our matches would show. Not critical. Actually — public shouts are part of the club's voice; the playbook says "Shouts are public and in our voice: short, sporting". If _valid drops the shout, we've been silent. I could pass shout through in _valid (validated: string, ≤60 chars). Small win for identity, zero cost. But careful: the reply contract — "applied" includes skill/target/lead_s. Does the engine accept "shout" in the applied dict? The decisions log shows applied with skill/target/lead_s only, but that's Synthetic Athletic (maybe they don't shout). comms.jsonl exists for matches, so shouts are a thing. I'll pass "shout" through if it's a short string — if the engine ignores it, no harm. Hmm, but if the engine REJECTS unknown fields... _valid is my own validator; the engine's contract for the returned dict from decide() — the reference implementation would show. Risk: low. Actually, to be safe: keep the return shape exactly as the current code produces (skill, target, lead_s, and shout if the current code has it). I'll see in the read.
Let me do the read now. Actually — to save a turn, could I write the file without reading? No — I'd risk breaking working shell logic I can't fully recall (hysteresis constants, ball memory, wall clamp, cover position math). The read is worth it. 6.6KB, one turn.
Actually wait, I already have the tail from 4400-6618. I need 0-4400. One read with offset 0 gets 24KB → whole file anyway. Fine.
Let me also plan the exact new decide() logic:
```python
def decide(self, obs):
self_s = obs.get("self") or {}
if self_s.get("fallen"):
return {"skill": "hold"} # no model call, instant
ball = self._ball(obs) # existing memory helper
presser, switched = self._role(obs, ball)
if presser != self.shirt:
# COVER: pure shell, no model call.
target = self._cover_target(obs, ball)
return {"skill": "walk_to", "target": target}
# PRESSER: model call only when the decision is non-obvious.
if ball is not None and ball["distance_m"] <= 2.5:
reply = self._agent_call(obs) # existing call+validate+fallback
if reply: return reply
# fallback: chase
return {"skill": "go_to_ball"}
```
Hmm, but what about when the presser is far from the ball and the ball is in our defensive third — maybe the LLM would choose to hold position? No: presser's job is to press. go_to_ball is right.
What about ball not seen (memory expired)? Current code: hold shape / go to last known? I'll see. Probably walk to a home position. Keep existing behavior minus the model call.
One risk: if the LLM is NEVER called for a long stretch (e.g., ball always >2.5m from presser), our players never shout and the "LLM brain" never engages — but the shell is sound. The digest will show fewer decisions, lower latency, ~0 missed deadlines. That's the win.
Also — the presser when close: the LLM chooses kick_toward targets (corners etc.). Good use.
What about the cover robot intercepting passes (playbook gap)? Not this session — one disease per session. The disease: wasted calls → missed deadlines.
Now, the cover target: existing code computes it (ball→own-goal line, 2m goal-side, clamped off walls). I'll reuse exactly.
Edge: what if BOTH robots think they're cover (presser assignment is shared state, consistent). Fine.
What about "switched" — on a role switch, maybe shout "mine!"? Without a model call, a canned shout: {"skill": "go_to_ball", "shout": "mine"}. If the engine accepts shout in the dict. I'll check what the current code returns for shouts. If current code never includes shout, I'll include it only if I see evidence the contract supports it (e.g., in the reference or rules I read earlier — can't recall). Safer: match existing return shapes exactly. The identity loss is minor; correctness is major. Hmm... actually the comms.jsonl in our s0 match had content (2KB) — so someone shouted. Whatever — keep shapes as-is.
OK, do the read. Then write. Then lint. Then practice if clock allows (it verifies load + gives latency numbers). Then note + done.
Actually, let me reconsider practice: it plays current code vs mirror, costs player-model spend from session budget ($0.36 spent of $2.50 so far; practice with our reduced call rate should be cheap — maybe $0.10-0.30). The value: verify the new code actually loads and runs in a real match (lint checks imports but not runtime logic like my role gating). A crash on match day = last-good-commit plays = this whole session wasted. Practice is the only runtime verification I have. YES, practice — 90 seconds. But the clock: 15m04s left. Read (~30s), write (~60s), lint (~10s), practice (90s+overhead), note (~30s), done (~10s). Feasible if no more 504s.
Hmm, one thing about practice: "your current code vs a mirror of itself" — both sides my code. It'll show decision counts and latency in the event tape. Good enough to verify the call-gating works (decisions should drop ~50%+, missed deadlines ~0).
Let me write the turn: brief prose + read team.py.
Actually — can I skip the read and reconstruct from the tail + memory? The condensed log shows I read team.py fully twice. But I can't recall verbatim the first 4400 chars (GLMPlayer.__init__, decide, _ball memory, _cover_target, _clamp, shout handling). Rewriting from scratch risks subtle breaks (e.g., obs key names: "self", "field_xy", "detections" — I have those from the decisions log; the helpers' exact behavior I'd reinvent). The read is one turn of ~30s. Worth it. Do it.
Prose: short — "Clock is short, so: read my full team.py once, then rewrite decide() so the model is only called when its answer is used (presser, ball close, not fallen). Cover and fallen paths become instant shell actions."
Then JSON read.
Clock's short and my diagnosis is settled, so here's the plan for the remaining turns: read my full `team.py` once (I need the exact shell helpers to keep), then rewrite `decide()` so the model is called **only where its reply is used** — never when fallen, never for the cover robot (whose reply the shell discards anyway), and for the presser only when the ball is close enough that kick/target choice actually matters. Every other path becomes an instant shell action. That alone should cut our model calls by well over half and end the missed-deadline bleed.

(0.0s)Thought for 2,498 words
Let me take stock. I have 6 turns left, $0.40 spent of $2.50, 9 minutes of clock left. Wait — the clock says 9m04s of 1h30m left. That's very short. I need to be decisive NOW.
My diagnosis: 178/184 missed deadlines at ~2.46s latency. The decisions.jsonl slice I read was actually from Synthetic Athletic's perspective (robot 0/1, team "Synthetic Athletic") — wait, no. The private decisions log for m3_synthetic_athletic_frontier_glm — the records show "team": "Synthetic Athletic". Hmm, interesting — that's the private log but it seems to contain the opponent's decisions? Actually wait, the file is data/private/s3/m3_synthetic_athletic_frontier_glm/decisions.jsonl — that's MY club's private decisions. But the records show team "Synthetic Athletic" with attack_goal_xy [7.0, 0.0] and defend_goal_xy [7.0, 0.0] — both the same, which is odd. Actually maybe the "you" block is mislabeled or the log includes both teams. Not worth investigating now.
Key facts from the slice: latency_s values 3.93 (missed deadline), 1.265, 2.23, 1.027 — these are the opponent's (Synthetic Athletic, flash-lite) latencies, and even they hit 2.23s sometimes. My team's mean was 2.46s with 178/184 missed.
The critical structural insight from my team.py read: `decide()` calls `self.agent.decide(obs)` FIRST, unconditionally, before checking fallen/role. The shell then discards the reply for the cover robot entirely (it computes its own walk_to target) and for fallen robots. So we're paying full model latency on every decision even when the reply is thrown away. The fix: only call the model when the reply will actually be used — i.e., when not fallen AND when this robot is the presser (and maybe only when close to ball). Everything else: instant shell action, zero latency, zero missed deadlines.
Also the observation includes camera frames (2 frames attached) — that's likely where the 16k input tokens come from. I can't change the obs the agent factory receives... unless the agent factory accepts options. I didn't get to read the reference team.py (FileNotFoundError). But I can control what I pass: `make_football_agent` — I saw the tail of team.py was truncated at "def build_team(ctx): from gauntlet.football import..." — I need to see the rest of build_team to know the factory call signature. The file is 6KB and I read up to ~4400+ chars; the truncated part is the build_team function. I have 6 turns left and 9 minutes. I must not waste turns.
Options:
1. Read the rest of team.py (offset ~4400) to see build_team — 1 turn.
2. Write the new team.py — 1 turn.
3. Lint — 1 turn.
4. Note + done — 1-2 turns.
That's 4-5 turns. Tight but feasible. Practice would cost a turn and money; with 9 minutes left, maybe skip practice or do one short one. Actually practice is important to verify, but the clock is the bigger risk. The playbook says "Never commit unlinted code" — lint is mandatory. Practice is "max 2" but not mandatory. Given 9 minutes and 6 turns, I'll skip practice or do a very short one if turns remain. Actually, a practice match spends player-model calls from session budget — and my new code is designed to call the model LESS, so it's cheap. But time... Let me prioritize: read tail of team.py, write new team.py, lint, note, done. If I have a spare turn, practice 60s.
Actually, do I even need to read the tail? The build_team function constructs the agents via gauntlet.football factory. I need to know exactly how it's called to preserve it in my rewrite. Since write replaces the whole file, I must reproduce build_team exactly. I only saw "def build_team(ctx):\n from gauntlet.football import..." — truncated. So yes, I need that tail. One read at offset 4400.
Wait — the earlier session log shows I already did "[read club/team.py@4400]" twice and both times got cut off by 504s before seeing content? Actually the log shows the tool was called but the result isn't shown in the condensed log. The last full read I got shows up to "def build_team(ctx):\n from gauntlet.football import...[truncated]". So I still need the tail. One turn: read offset 4400.
Then the rewrite. Key changes to decide():
1. Check fallen FIRST, return hold immediately — no model call.
2. Compute ball/mate/role assignment FIRST (pure shell, no latency).
3. Only call the model if: not fallen AND I'm the presser AND ball is visible (and maybe within some engagement distance, say 3.5m — actually let me keep it simpler: presser + ball seen). The cover robot never calls the model — its action is fully determined by the shell. This halves calls immediately and makes cover decisions instant (zero missed deadlines for cover).
4. For the presser, still wrap in try/except with the shell fallback (kick at goal inside 1.2m, else go_to_ball).
5. Keep say handling: only presser can say something. Maybe add a cheap occasional shout? Keep it minimal.
Also: should the presser skip the model when far from the ball? If the presser is 5m from the ball, the right action is almost always go_to_ball — the model adds nothing. But there are edge cases (opponent closer, better to hold shape). To be safe and still cut calls hard: call the model only when presser AND ball seen AND dist(me, ball) <= some threshold like 4.0m. Beyond that, go_to_ball is obviously right. Hmm, but if the presser is far and the ball is far from everyone... go_to_ball is still right. I'll use 4.0m engagement radius. Actually, let me think about what fraction of decisions that leaves: presser role ~50% of decisions, ball within 4m maybe 60% of those → ~30% of current call volume. That's a 3x cut in model spend AND the cover robot's decisions become instant (0 latency, 0 missed deadlines).
Wait, one concern: missed deadlines. What causes a "missed deadline"? The decision_interval_s is ~2.0-2.3s. If the model takes longer than that, the decision is discarded. Our mean latency 2.46s > 2.33s interval → most decisions discarded. When discarded, what happens? Presumably the previous action continues or a default. The digest said 178/184 missed. So effectively our players were running on ~3% of their decisions — the shell fallback... wait, no. If the reply is discarded by the engine, our decide() return value... hmm. Actually the missed_deadline is recorded in the decisions log with "applied": null — the decision was discarded, meaning the engine didn't apply anything new; the robot presumably continues its previous skill. So our robots were mostly running stale/first decisions. Yet we only lost 4-3! The shell must have been producing decent actions when it did land.
Hmm wait, actually — re-reading: the decisions.jsonl records show "raw" (what the model replied), "applied" (what got applied), "status". For our club, 178/184 were missed_deadline. But our decide() returns the shell-validated action — the "applied" field would be our shell output. If the engine discards our return because we took too long... the latency is measured on our decide() call as a whole, which includes the model call. So the fix (fewer/no model calls on most paths) directly fixes latency: cover robot decide() becomes ~0ms, presser decide() still pays model latency when called.
But even the presser's model call may exceed 2.3s (mean 2.46s!). The registry says luna warm latency 0.6-0.9s but we observed 2.46s mean with ~16k input tokens. The camera frames (2 frames) are likely attached as images — that's the token bloat and latency. Can I avoid sending frames? The obs includes "camera": {"frames": 2, "note": "raw frames also attached (_frames) if you prefer your own vision"}. The agent factory presumably reads obs and constructs the prompt including frames. If make_football_agent has an option to disable vision... I don't know the factory signature. I saw only the import line. The reference team.py read failed (FileNotFoundError — weird).
I could try reading reference/club/team.py again — but it failed twice with FileNotFoundError. That's a league tool bug worth reporting, but reporting costs a turn. With 6 turns and 9 minutes, a report is a luxury. Actually the report tool is free budget-wise but costs a turn. Hmm. The earlier failures might have been transient. But I can't afford to gamble turns. My rewrite doesn't strictly need the factory signature — I keep build_team as-is (just re-read its tail to reproduce it exactly).
Alternative: strip the camera frames from obs before passing to the agent! In decide(), I control what I pass: `self.agent.decide(obs)`. I could pass a shallow-copied obs with the "_frames" key removed (and "camera" note). If the frames are attached as obs["_frames"], removing them cuts input tokens massively → latency drops toward the registry's 0.6-0.9s. The note says "raw frames also attached (_frames) if you prefer your own vision" — so the default agent presumably uses its own detection processing, and frames are optional ("if you prefer"). Removing _frames should be safe for the league agent and hugely cut tokens.
But wait — do I know the agent uses _frames? The note says frames are attached "if you prefer your own vision" — implying the standard agent does NOT need them, they're optional extra. If the standard agent's prompt includes them anyway (as images), that's the 16k tokens. Stripping them is the single highest-leverage change. Risk: if the agent factory requires _frames key present... unlikely, it says "if you prefer".
So my decide() for the presser:
```python
obs_lite = dict(obs)
obs_lite.pop("_frames", None)
r = self.agent.decide(obs_lite)
```
That's cheap and safe (dict copy, no mutation of original).
Let me now write the new team.py fully. I'll keep everything from the current file (shell, _assign, _valid, _ball, _teammate) and restructure decide():
```python
def decide(self, obs):
self_state = obs.get("self") or {}
if self_state.get("fallen"):
return {"skill": "hold"}
you = obs.get("you") or {}
own_goal = you.get("defend_goal_xy") or [0.0, 0.0]
atk_goal = you.get("attack_goal_xy") or [0.0, 0.0]
me = self_state.get("field_xy") or [0.0, 0.0]
ball = self._ball(obs)
mate = self._teammate(obs)
presser, took_over = self._assign(ball, me, mate)
say = None
out = None
if ball is not None and presser == self.shirt and _dist(me, ball) <= ENGAGE_M:
# Only here is a model reply both useful and used.
reply = {}
try:
obs_lite = {k: v for k, v in obs.items() if k != "_frames"}
r = self.agent.decide(obs_lite)
if isinstance(r, dict):
reply = r
except Exception:
reply = {}
out = self._valid(reply)
say = reply.get("say")
if out is None:
if _dist(me, ball) <= KICK_RANGE_M:
out = {"skill": "kick_toward", "target": _clamp(atk_goal)}
else:
out = {"skill": "go_to_ball"}
if took_over and not say:
say = "Mine!"
elif ball is not None and presser == self.shirt:
# Presser but far from the ball: chase, no model needed.
out = {"skill": "go_to_ball"}
if took_over:
say = "Mine!"
else:
# Cover (or ball lost): hold the ball-goal line.
if ball is not None:
gx = own_goal[0] - ball[0]
gy = own_goal[1] - ball[1]
n = math.hypot(gx, gy) or 1.0
target = _clamp([ball[0] + gx / n * COVER_OFFSET_M,
ball[1] + gy / n * COVER_OFFSET_M])
else:
target = _clamp([(own_goal[0] + me[0]) / 2.0,
(own_goal[1] + me[1]) / 2.0])
out = {"skill": "walk_to", "target": target}
if say:
out["say"] = str(say)[:120]
return out
```
Wait — there's a subtlety with the presser far from ball: if the presser is beaten or the ball is behind, go_to_ball is still right. Fine.
ENGAGE_M = 4.0.
Hmm, one more consideration: when the presser is within ENGAGE_M, we call the model — but if the model is slow (2.4s), those decisions still miss deadlines. Stripping _frames should cut latency a lot. Also, with the cover robot no longer calling, the two robots' calls don't contend (if the agent factory serializes calls per process, halving calls halves contention).
Also begin_episode: keep.
One more thing — the "say" channel: with the model called less, we shout less. Fine — shouts are flavor.
Also should the cover robot ever get the ball? If ball rolls to the cover robot's feet... the shell says cover never kicks. The _assign hysteresis would flip roles only if distances clearly favor. If the ball is at the cover robot's feet, mate_d (presser's distance) > my_d + 1.5 → role flips, cover becomes presser, then within ENGAGE_M → model called or kick fallback. OK, that works — role assignment is distance-based with hysteresis, so the nearer robot eventually takes over. Good enough.
Now build_team — I need its exact tail. Let me read offset 4400 first. Actually the file is 6KB = ~6000 chars; my read showed content up to "def build_team(ctx):\n from gauntlet.football import..." then [truncated]. The read tool serves 24KB, so why truncated? Because the harness display truncated it in the log? The earlier full-file read at the top of this session showed the same cutoff at build_team. Odd — maybe the log condensed it. The safest: one read with offset 4400 to get the tail. That's turn 1.
Then write the full new file (turn 2), lint (turn 3), note (turn 4), done (turn 5). Leaves 1 spare turn for practice (60s) or fixing a lint error. Given 9 minutes of clock — wait, the clock says 9m04s left of 1h30m. That's brutal. Each of my turns also spends wall-clock. A practice match of 60s plus render time might eat 2-3 minutes. Risky but if turns remain after lint, worth it. Actually — with 9 minutes, I should skip practice and make the commit safe. The change is conservative (same shell, just fewer model calls + frame stripping). Lint verifies it loads. Practice would verify behavior, but the shell logic is unchanged except the far-presser branch (go_to_ball — trivially safe).
Hmm, but wait: one risk in stripping _frames — if the agent factory's decide() expects obs["_frames"] to exist... The note says "raw frames also attached (_frames) if you prefer your own vision" — "if you prefer" strongly implies optional. And I keep the "camera" key (frames: 2 count) intact. Low risk. And even if the agent errors, my try/except catches it and falls back to shell action. Safe.
Another thought: should I also strip "camera"? The camera dict is tiny (frames: 2, note). Keep it.
What about the opponent's last shout / teammate_says — those are in obs already, tiny. Keep.
Let me also double check _assign: it uses self.shared["shirts"] — set where? Probably in build_team: shared = {"shirts": {...}}. I need the tail to confirm. Yes, read tail first.
Plan for this turn: brief prose + read offset 4400. Actually — can I combine? No, exactly one JSON object per turn. OK.
Turn 1 (now): read club/team.py offset 4400.
Turn 2: write new club/team.py (full file).
Turn 3: lint.
Turn 4 (if lint clean): practice 60s? or note. With 9 min clock... practice 60s costs ~1-2 min wall. If lint passes at ~7 min left, practice 60s, then note+done. Tight. Alternative: skip practice, note, done, keep 2 spare turns for lint fixes. I'll decide based on the clock after lint.
Actually, let me reconsider: is there any chance the write is wrong because I mis-reproduce build_team? The read will give it to me verbatim. Fine.
Let me write the prose + JSON now. Keep prose short.
Nine minutes and six turns left — no more exploration, execution only. The plan is settled: call the model **only** where its reply is used (never when fallen, never for the cover robot, never for a presser far from the ball), and strip the attached camera frames from the obs we pass in — that frame payload is where ~16k input tokens per call and 2.46 s latency come from. First I need the exact tail of `team.py` (the `build_team` factory call) so my rewrite reproduces it verbatim.

backoff of 20s would outlast the 1h30m session cap — stopping here rather than sleeping through the end.
Session over. Everything the club changed was committed to its own public repository.
