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 | $0.00202 | $0.00202 |
| Opus 5 | $0.00101 | $0.00101 |
| Sonnet 5 | $0.00040 | $0.00040 |
| Haiku 4.5 | $0.00020 | $0.00020 |
Grade A, and why
mcpm.sh CLAUDE.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 8d 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
Claude Project Conventions
This file contains conventions that Claude should follow when working on this project.
- Dependency Management: Use
uvfor all Python dependency management. - Python Environment: You are in the uv
.venvPython environment. All dependency code can be found in.venv/. - Formatting: Always format Python code with
ruff. - Committing:
- NEVER commit anything to git unless explicitly asked to do so.
- Always double-check with the user before committing changes to git.
- This project follows semantic release - commit messages MUST follow Conventional Commits format.
- Examples:
feat:,fix:,docs:,style:,refactor:,perf:,test:,chore: - BREAKING CHANGES: Adding
BREAKING CHANGE:in the commit footer triggers a major release. This is very uncommon - NEVER do this unless explicitly told to do so.
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.

mcpm.sh CLAUDE.md is an instructions file published in the GitHub repository pathintegral-institute/mcpm.sh (997 stars, last pushed 16d ago), licensed MIT. It adds 202 tokens to every session, about $0.0010 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.
