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 | $0.02157 | $0.02157 |
| Opus 5.5 | $0.00863 | $0.00863 |
| Sonnet 5.5 | $0.00431 | $0.00431 |
| Haiku 4.5 | $0.00216 | $0.00216 |
Grade A, and why
ai-skills 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 6d 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 — 184 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
This is the AI Skills project, which provides security hooks and testing infrastructure for Claude Code projects. The main features are:
- Security scanning to prevent sensitive data from being sent to external MCP services
- Branch protection to enforce PR-based workflows by preventing direct edits to protected branches (main, master, production, release)
Marketplace Structure
The repository is organized as a marketplace with 10 installable plugins:
- security-hooks: MCP security scanner and protected branch hooks
- dev-skills: Expert skills for Go, documentation, and architecture
- git-workflow: Git automation for commits, PRs, and changelog
- pm-tools: Project management commands for PRDs and tasks
- code-quality: Code quality analysis, review, and cleanup
- prompt-tools: AI prompt generation and review tools
- pr-review-triage: Triage of PR review comments and follow-up tracking
- forgejo-review: Advisory Forgejo pull-request review workflow
- nix-skills: Expert guidance on Nix, NixOS, and home-manager
- eval-workflow: Eval scenario generation and offline verification

Key Commands
All project operations are managed through the Makefile:
make test # Run complete test suite
make lint # Run ShellCheck on all shell scripts
make install # Install hooks (make scanner script executable)
make sync-codex-skills # Sync .codex/skills symlinks with plugins/*/skills
make clean # Remove test artifacts and logs
make status # Show current status and configuration
make check-tools # Check for required and optional security tools
make help # Display all available commands
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.
