Skill Health Monitor

> Automated health checks for your agent skill collection

Purpose

Audit, score, and maintain the health of your AI agent skills. Catch rotting skills, missing files, broken triggers, and outdated content before they cause silent failures.

When to Use

• "check skill health", "audit my skills", "skill inventory"
• Periodic maintenance (weekly/monthly)
• Before adding new skills to a collection
• When agents start behaving unexpectedly

Health Rating

Audit Commands

# Check single skill directory
check-skill-health ./path/to/skill

# Scan entire skill collection
scan-skills ./skills/ --report=health-report.md

# Compare health over time
skill-health diff --baseline=health-report-2026-03.md --current=health-report-2026-04.md

Quick Audit Checklist

Run this on each skill:

1. cat SKILL.md — Does it exist? Is the description clear?
2. grep -r "TODO\|FIXME\|HACK" — Any technical debt markers?
3. git log --since="30 days ago" --oneline — Any recent activity?
4. grep -i "trigger\|when to use\|example" SKILL.md — Are triggers and examples defined?
5. Check for hard-coded paths, URLs, or deprecated tool names
