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 | $0.00645 | $0.00645 |
| Opus 5 | $0.00322 | $0.00322 |
| Sonnet 5 | $0.00129 | $0.00129 |
| Haiku 4.5 | $0.00064 | $0.00064 |
Grade A, and why
anyclaude AGENTS.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 — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Structure & Module Organization

Build, Test, and Development Commands
- Install:
bun install. - Build:
bun run build(outputsdist/main.jswith Node shebang). - Run CLI (after build):
./dist/main.js --model openai/gpt-5-mini. - Dev run (no build):
PROXY_ONLY=true bun run src/main.ts(prints proxy URL)OPENAI_API_KEY=... bun run src/main.ts --model openai/gpt-5-mini
- Nix shell:
direnv allow(ornix develop); format Nix/shell files withnix fmt.
Coding Style & Naming Conventions
- Language: TypeScript (ESNext, strict mode enabled).
- Indentation: 2 spaces; keep lines reasonable; use explicit imports (
verbatimModuleSyntax). - Files: kebab-case
.ts(e.g.,convert-to-anthropic-stream.ts). - Names:
camelCasefor variables/functions;PascalCasefor types/classes. - Exports: prefer named exports; keep modules single‑purpose and small.
Testing Guidelines
- No test runner is configured yet. If adding tests:
- Place under
src/**/*.test.tsorsrc/__tests__/. - Prioritize pure units (converters, schema, MIME detection). Avoid live provider calls by default; gate with env vars.
- Add a
testscript inpackage.jsonand document how to run it inREADME.md.
- Place under
Commit & Pull Request Guidelines
- Commits: imperative, concise subjects (e.g., "Add Nix development environment and Claude guidance file"). Include rationale in the body when helpful.
- PRs: clear description, linked issues, commands used to verify (with relevant env vars), and expected behavior. Avoid committing secrets; scrub logs.
- Keep scope small; update
README.md/CLAUDE.mdwhen behavior or env vars change.
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.

anyclaude AGENTS.md is an instructions file published in the GitHub repository coder/anyclaude (292 stars, last pushed 1y ago), licensed MIT. It adds 645 tokens to every session, about $0.0032 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.
