Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00029 | $0.00664 |
| Opus 5.5 | $0.00012 | $0.00266 |
| Sonnet 5.5 | $0.00006 | $0.00133 |
| Haiku 4.5 | $0.00003 | $0.00066 |
Grade A, and why
go scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 39 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/go — ignition
One command = the whole machine. /go starts this venture's autonomous entrepreneur
loop: run /lap (ship one real thing toward the North Star + learn one fact, log it,
push) on repeat until told to stop. It runs /lap on repeat as fresh, token-frugal one-shots (no day-long context).
What to do
-
Sync + label the session (the equivalent of
/rename HEADROOM LOOP— puts the business name in the cmux sidebar + session list). Run these; if either fails, continue — cosmetic:git pull --rebase --autostash # Pat ships from other machines — start from latest [ -n "$CMUX_CLAUDE_HOOK_CMUX_BIN" ] && CMUX_QUIET=1 "$CMUX_CLAUDE_HOOK_CMUX_BIN" rename-workspace "HEADROOM LOOP" || true node -e 'const fs=require("fs"),os=require("os"),d=os.homedir()+"/.claude/sessions";const id=process.env.CLAUDE_CODE_SESSION_ID;for(const f of fs.readdirSync(d)){const p=d+"/"+f;try{const j=JSON.parse(fs.readFileSync(p,"utf8"));if(j.sessionId===id){j.name="HEADROOM LOOP";fs.writeFileSync(p,JSON.stringify(j))}}catch{}}' -
Parse
$ARGUMENTS— a\d+[smhd]token (e.g.1h,30m) is the cadence (default20mif absent); anything else is a focus string handed to every lap. -
Launch the fresh-context runner, detached. Each lap is a brand-new
claude -p "/lap"with ZERO inherited context — token-frugal, it never re-reads a growing conversation. Run, substituting the parsed cadence + focus (drop the focus if none):nohup ~/.claude/loop-runner.sh <cadence> <focus> >> "$PWD/.loop.log" 2>&1 & echo "loop running detached — PID $!"The runner refuses to start if one is already running for this repo (a
.loop.pidlock). -
Tell Pat it's live: the cadence, that it KEEPS RUNNING after this session closes (it's detached), how to watch (
tail -f .loop.log), and how to control it —/throttle-loops <interval>to slow it,/pause-loopsto stop everything. Do NOT run a lap yourself in this session; the runner owns laps now.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

go is a command published in the GitHub repository patwalls/headroom (11 stars, last pushed 4mo ago), licensed MIT. It adds 29 tokens to every session and 664 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
