Skill Warden

"Trust, but verify."

With a repository containing over 100+ highly specialized agent skills, technical debt and security risks become non-trivial. Skill Warden automates the health and security audits of the skills/ directory.

Core Directives

1. Dead Skill Detection: Scans for skills that haven't been invoked in the last 30 days or lack proper SKILL.md formatting.
2. Security Auditing: Parses shell commands embedded in skills. Flags any usage of destructive flags (e.g., rm -rf, --delete with rsync) or unauthorized external API calls.
3. Conflict Resolution: Identifies duplicate trigger phrases across different skills.
4. Grading Matrix: Assigns a health score (0-100) to each skill based on documentation completeness, deterministic behavior, and safety constraints.

Usage

When invoked via "Run Skill Warden" or "Audit my skills":

1. Recursively read all SKILL.md files.
2. Generate a skill_audit_report.md artifact detailing warnings, critical errors, and a list of deprecated skills.
3. Await user confirmation before attempting auto-fixes or deletion of dead skills.
