Skill Lab

Skill Lab is a toolkit for analyzing and understanding AI agent skills.

It helps to inspect skill behavior before enablement by producing deterministic permission and risk output.

The project is still experimental. Feedback and PRs are welcome.

What it provides

• Deterministic static analysis for skills from local paths or GitHub.
• Structured permissions and risks output for review and automation.
• Aggregate score, riskLevel, and summary for fast triage.
