Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00037 | $0.02770 |
| Opus 5 | $0.00018 | $0.01385 |
| Sonnet 5 | $0.00007 | $0.00554 |
| Haiku 4.5 | $0.00004 | $0.00277 |
Grade A, and why
agent-audit 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 9d 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 — 387 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent Auditor
Validates agent configurations for model selection, tool restrictions, focus areas, and approach methodology.
Quick Start
Basic audit workflow:
- Read agent file
- Check model selection appropriateness
- Validate tool restrictions
- Assess focus area quality
- Review approach methodology
- Generate audit report
Example usage:
User: "Audit my evaluator skill"
→ Reads skills/evaluator/SKILL.md
→ Validates model (Sonnet), tools, focus areas, approach
→ Generates report with findings and recommendations
Agent Audit Checklist
Critical Issues
Must be fixed for agent to function correctly:
- Valid YAML frontmatter - Proper syntax, required fields present
- name field matches filename - Name consistency
- model field present and valid - Sonnet, Haiku, or Opus only
- At least 3 focus areas - Minimum viable expertise definition
- Tool restrictions present - allowed_tools or allowed-patterns specified
- No security vulnerabilities - Tools don't expose dangerous capabilities
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-audit is a skill published in the GitHub repository majiayu000/claude-skill-registry (600 stars, last pushed yesterday), licensed MIT. It adds 37 tokens to every session and 2,770 once invoked, about $0.0002 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 2026-09-01.
