Skill Audit

Purpose

Systematically validate Claude Code / Agent Skills directories for correctness, security, and quality. Combines static analysis (deterministic checks) with AI reasoning (judgment on trigger scope, coexistence, context efficiency).

Workflow

Step 1: Static Analysis

Run the bundled auditor from the repository root:

python skills/skill-audit/scripts/skill_audit.py <skill-path> --surface claude-code

For agent-api mode (strict, requires name and description):

python skills/skill-audit/scripts/skill_audit.py <skill-path> --surface agent-api

JSON output for programmatic use:

python skills/skill-audit/scripts/skill_audit.py <skill-path> --json

Exit code is non-zero when the worst score drops below 70.

Step 2: Read the Skill

Read SKILL.md and any directly referenced files (scripts, references, assets). Do not read files that are not referenced — they are background context only.

Step 3: AI Judgment Review

Assess four areas that static checks cannot cover:

Discovery problems

• Is the description narrow enough to avoid false triggers?
• Does it overlap significantly with adjacent skills in the same directory?
• Would a model reliably select this skill for its intended use cases?

Isolation problems

• Are all referenced files present and accessible?
• Does the skill rely on environment assumptions not stated in compatibility?
• Are external dependencies (APIs, CLIs, credentials) documented?

Coexistence problems

• Does this skill's description overlap with other skills in the directory?
• Could two skills be triggered simultaneously causing conflict?
• Are trigger boundaries clear and mutually exclusive where needed?

Efficiency problems

• Is SKILL.md under 500 lines? (warn above this threshold)
• Is large reference content in separate files rather than inline?
• Does the skill regenerate the same code on every run that could be a script?
• Are volatile business rules or policies externalizable?

Step 4: Report

Present findings in three severity buckets:

## Skill Audit: <skill-name>

**Score**: <0-100> | **Surface**: <claude-code|agent-api>
**Static findings**: N errors, N warnings, N info

---

### Blockers

Issues that prevent safe use or deployment.

- [ERROR] <code> @ <file>:<line> — <message>
  **Why it matters**: <impact>
  **Fix**: <exact change>

### Important

Issues that reduce reliability or increase risk.

- [WARN] <code> @ <file>:<line> — <message>
  **Why it matters**: <impact>
  **Fix**: <exact change>

### Optional

Improvements that increase efficiency or clarity.

- [INFO] <code> — <message>
  **Suggestion**: <recommendation>

### Evaluation Gaps

Missing test cases for the eval suite:

- should-trigger: <prompt that should activate this skill>
- should-not-trigger: <prompt that should NOT activate this skill>
- ambiguous: <edge case worth tracking>

### Efficiency Notes

<Estimate where the skill wastes context, time, or tool calls>

If the score is 100 and no AI judgment issues are found, report:

## Skill Audit: <skill-name>

**Score**: 100 | No issues found. Safe to use as-is.

Static Checks Covered

Bundled Resources

Integration

• Run in CI on every change to any skill directory
• Add a Claude Code hook that triggers this audit after edits to .claude/skills/**
• Gate new skill versions on a passing score (≥ 70)
• Pair with validate-fix to automatically resolve discovered issues
