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 | $0.00427 | $0.00427 |
| Opus 5.5 | $0.00171 | $0.00171 |
| Sonnet 5.5 | $0.00085 | $0.00085 |
| Haiku 4.5 | $0.00043 | $0.00043 |
Grade A, and why
agents-md-facts 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 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.

Conventions
- TypeScript strict mode (tsconfig.json)
- ESM modules (
type: module) - Style enforced by ESLint — obey the configs
Guardrails
- Always OK: read files, run the tests (
bun run test), build the project. - Ask first: dependency installs, deletions, migrations / schema changes.
- Never: force-push, push to
main, commit secrets.
Definition of Done
Done when: bun run lint exits 0 · bun run typecheck exits 0 · bun run test passes · committed with a clear message.
Commit & PR
- Write a clear, descriptive commit message.
- Branch off
main; never commit tomaindirectly — open a PR for review. - If build/test scripts or layout change, refresh this file in the same PR (
npx agents-md-facts).
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.
