# Skill Test

Check a skill holds up before you rely on it

## What this does

You wrote a skill and want to know whether it is sound before depending on it. This validates skill files in three ways: a linter for structure, a behavioral check against what the skill is supposed to do, and a coverage report. Pick the mode that matches the question you have.

### Top 3 things it does for you

- Lint a skill file for structural problems
- Check a skill behaves the way it is supposed to
- See how much of your skill set is covered

## About Skill Test

This validates skill files for both structural compliance and behavioral correctness.

It runs in three modes: static, which acts as a linter; spec, which checks behavior; and audit, which produces a coverage report.

## Questions

### Is Skill Test safe to install?

AIR scanned this exact version of Skill Test and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 984023ddac0d, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/skill-test.

### How do I install Skill Test?

Open https://airmarket.ai/app/skill-test on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up.
