skill-auditor

skill-auditor is a skill for Claude Code, Codex from AtlasOmnia/hermes-custom-pack. It costs 64 tokens per session (3,399 once invoked), scanned A, a copy of skill-auditor, MIT.

A review process for evaluating a coding-agent skill file against criteria such as clarity, completeness, tool guidance, and ease of sharing. It assigns a grade and lists specific improvements.

In plain words
What is it for?
Use it to review, grade, troubleshoot, or prepare skill files for distribution.
Why use it?
It helps find instructions that may be unclear, incomplete, or unreliable before others depend on them.

Token cost

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.

Security

Grade A, and why

skill-auditor 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 4d 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 — 270 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Skill Auditor — Quality Grading System (A–F)

Audit any Hermes skill file and assign a quality grade based on clarity, completeness, tool guidance, and shareability. Returns specific fix suggestions ranked by impact.

When to Use

  • User asks you to review, audit, or grade a skill
  • You're about to create a new skill and want to validate the draft
  • A skill is behaving unreliably (agent skips it, calls wrong tools, misses steps)
  • User shares a skill file or path for feedback
  • You're preparing skills for sharing with others

Don't use for: general Hermes troubleshooting, model selection, config review — those have their own skills.

Grading Criteria

Each skill is scored across five dimensions. Points are deducted from 100. The final grade maps to a letter:

  • Grade A (90–100) — Production-ready. Solid frontmatter, exact commands, real pitfalls, verification steps, consistent structure. Will fire reliably and execute correctly across model sizes.
  • Grade B (80–89) — Minor gaps. Missing one dimension but still reliable.
  • Grade C (70–79) — Functional but vague in places. Needs clarification on 1–2 key areas, especially with smaller models.
  • Grade D (60–69) — Error-prone patterns detected. Incomplete steps or missing critical sections. Will fail silently on model switches.
  • Grade F (<60) — Broken discovery or execution. Either the description is too vague to fire, or the steps are too incomplete to follow.

Dimension 1: Frontmatter & Description (max 25 points)

The description is your skill's only chance to be discovered. Hermes sees the one-line description from available_skills before deciding whether to load SKILL.md at all. If that description is vague, the skill never fires — nothing inside SKILL.md matters if this step fails.

Full marks (25): Valid YAML frontmatter with name and description fields. Description starts with "Use when..." and covers the trigger class (not a single task). Specific enough that Hermes can distinguish it from similar skills. ≤ 1024 chars.

  • Example A: Use when debugging Python: test failures, uncaught exceptions, silent bugs. Covers root cause analysis, not just error messages.
  • Example B: Use when debugging code issues and test failures. (too broad — could overlap with other skills)

Changes

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.
