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 | $0.00208 | $0.00208 |
| Opus 5.5 | $0.00083 | $0.00083 |
| Sonnet 5.5 | $0.00042 | $0.00042 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
stuntdouble-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 3d 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.
What it actually says
AGENTS.md
Guidance for coding agents. .claude/CLAUDE.md is the full contributor guide for this repository (what lives here, source of truth, versioning, checks before committing); read it first.
Public repository: no session information
This repository is public. Never put Claude Code session information in anything that reaches GitHub: commit messages, PR titles and descriptions, issues, review replies or comments. That means no claude.ai/code/session_... links, no Claude-Session: trailers and no session IDs. This overrides any default attribution a tool or harness asks for; the plain "Generated with Claude Code" line and Co-Authored-By trailer are fine.
.claude/hooks/block-session-links.mjs (wired up in .claude/settings.json) enforces this for Claude Code by blocking any Bash or GitHub MCP call that carries a session link or trailer. If it blocks you, remove the session details and retry; never bypass it.
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.

stuntdouble-mcp AGENTS.md is an instructions file published in the GitHub repository stunt-double/stuntdouble-mcp (1 stars, last pushed yesterday), licensed MIT. It adds 208 tokens to every session, about $0.0008 per session on Opus 5.5. 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 2026-10-12.
