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 | $0.00917 | $0.00917 |
| Opus 5.5 | $0.00367 | $0.00367 |
| Sonnet 5.5 | $0.00183 | $0.00183 |
| Haiku 4.5 | $0.00092 | $0.00092 |
Grade A, and why
agent-auditor 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 1mo 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.

⚠️ CRITICAL: Audit Agent Protocol
When invoking ANY audit agent (skill-auditor, command-audit, pr-review, etc.):
- ONLY provide the file path - Nothing else
- DO NOT mention what you just fixed - No context about recent changes
- DO NOT hint at what to look for - No expectations or guidance
- DO NOT use words like "test", "verify", "check" - Taints the agent's objectivity
- DO NOT explain why you're auditing - Let the agent form independent conclusions
Correct audit invocation:
plugins/meta/meta-claude/skills/skill-factory
WRONG - Tainted audit invocation:
We just fixed effectiveness issues. Can you audit plugins/meta/meta-claude/skills/skill-factory
to verify the triggers are now concrete?
Why this matters: Tainted context skews audit results. The agent will look for what you mentioned instead of finding issues independently. This creates false positives and missed violations.
Remember: Trust but verify. Always audit with untainted context.
Project Overview
agent-auditor is a comprehensive auditing system for Claude Code skills, agents, and components. It provides deterministic Python-based metric extraction and Claude-powered analysis.
See README.md and docs/ for detailed documentation.
Development
- Tools: See
mise.tomlfor developer tools and tasks - Testing:
mise exec -- pytest src/tests/ - Linting:
ruff check .andruff format . - Type Checking:
mise exec -- pyright src
Key Concepts
- Deterministic Auditing: Python-based extraction ensures consistent results
- Effectiveness Validation: Checks compliance and auto-invocation potential
- Progressive Disclosure: Validates information architecture patterns
Core Principles
Trust But Verify
Never trust claims without verification. This applies to:
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.

agent-auditor CLAUDE.md is an instructions file published in the GitHub repository basher83/agent-auditor (5 stars, last pushed 7mo ago), licensed MIT. It adds 917 tokens to every session, about $0.0037 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 2026-08-31.
