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 | $0.02259 | $0.02259 |
| Opus 5.5 | $0.00904 | $0.00904 |
| Sonnet 5.5 | $0.00452 | $0.00452 |
| Haiku 4.5 | $0.00226 | $0.00226 |
Grade A, and why
rust-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 19d 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 — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md — rust-faf-mcp
This repository is the example of BEST on the FAF side of the ladder — not a slogan.
NONE → GOOD → BETTER → BEST
- BETTER is protocol honesty (mcp-better
main/mcp-better-better). Noproject.fafrequired. - BEST print slice (mcp-better
better-best/*/mcp-better-best) is the same software plusproject.faf. Falsifiable diff. That is the definition. - This crate is BEST on main: Trophy
project.fafand thisAGENTS.md. FAF defines. This file instructs. Sealed BLOCK from the DNA; working brief outside the markers. It is also a FAF MCP server, in Rust,one.faf/rust-faf-mcp— a crate people actually watch.
Do not collapse BETTER into BEST. Do not treat this markdown as the score. The score is project.faf (Mk4 100% ✪).
Read project.faf first. Do not edit the BLOCK. Refresh it with faf_agents. Everything below the BLOCK is how we work in this tree.

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.
