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 | $0.00927 | $0.00927 |
| Opus 5 | $0.00464 | $0.00464 |
| Sonnet 5 | $0.00185 | $0.00185 |
| Haiku 4.5 | $0.00093 | $0.00093 |
Grade A, and why
gemini-faf-mcp 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 today.
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 — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Conventions
- Quality Bar: zero_errors
- Testing: required
Guardrails
- All changes must pass 245 tests before commit
- faf-python-sdk handles parsing — server.py delegates
- Version must match in pyproject.toml, init.py, client.py, server.py, main.py
- Always OK: read the tree · run the tests (
pytest -q) · build the project ·ruff check .. - Ask first: dependency installs, deletions, migrations, schema changes, publish/release.
- Never: force-push · push straight to
main(branch and open a PR) · commit secrets.
Definition of Done
Done when: ruff check . exits 0 · mypy server.py models.py safe_path.py inject.py src/ exits 0 · pytest -q passes · changes committed with a conventional message.
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.

gemini-faf-mcp AGENTS.md is an instructions file published in the GitHub repository Wolfe-Jam/gemini-faf-mcp (2 stars, last pushed yesterday), licensed MIT. It adds 927 tokens to every session, about $0.0046 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 2026-08-31.
