Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.02090 | $0.02090 |
| Opus 5 | $0.01045 | $0.01045 |
| Sonnet 5 | $0.00418 | $0.00418 |
| Haiku 4.5 | $0.00209 | $0.00209 |
Grade A, and why
crow CLAUDE.md 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 2d 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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Working with this repo
- Always commit with a positional path arg:
git commit <path> -m "...", notgit add <path> && git commit -m "...". Parallel Claude sessions modify the working tree concurrently;git addthen a baregit commitwill sweep in unrelated WIP. Verify withgit show --stat HEADafter every commit. (See~/.claude/CLAUDE.mdLearnings 2026-04-14.) - Always
git pull --rebasebefore pushing a branch — parallel sessions commonly push tomainbetween your fetch and your push. - Tests:
npm testruns the FULL suite in a scratch env (safe on any box — it can never touch the real~/.crow; seescripts/run-suite.mjs). Node built-in test runner, no third-party framework. Single file:npm test -- tests/<file>.test.js(or rawnode --test tests/<file>.test.js— but NOT from a systemd-launched shell without the scratch env). Also verify a server starts cleanly:node servers/<name>/index.js(ctrl-C to exit) ornode servers/gateway/index.js --no-authfor the gateway. - CI red blocks ALL merges — including the operator's (decision Q6, 2026-07-18). The
Testsworkflow (.github/workflows/test.yml) runs the full suite +check-ports+build-registry --check+npm audit(critical/prod tier) on every PR and push to main, with no path filters — every commit gets check-runs now; an empty check-runs result on a current sha means something is WRONG, not normal. Queryhttps://api.github.com/repos/<owner>/<repo>/commits/<sha>/check-runs(public, no auth) and confirm every run iscompleted/successbefore merging (the legacy commit-status API omits Actions and can read green when a check is red). Job keyssuite/static-checks/auditare branch-protection contexts — never add aname:to those jobs or rename a key without updating protection. CI green does NOT cover schema migrations —SCHEMA_GENERATIONbumps still require the manual migration rail (scripts/schema-migration-dryrun.sh). Notably any new bundle host port must be added todocs/developers/port-allocation.mdorcheck-ports(scripts/check-port-allocation.js) fails. (See~/.claude/CLAUDE.mdLearnings 2026-06-28.)
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.

crow CLAUDE.md is an instructions file published in the GitHub repository kh0pper/crow (22 stars, last pushed 10d ago), licensed MIT. It adds 2,090 tokens to every session, about $0.0104 per session on Opus 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.
