Skill Checker
A comprehensive skill validation and review tool based on Anthropic's official "Complete Guide to Building Skills for Claude." This skill runs a multi-dimensional audit on any skill folder or SKILL.md and produces an actionable scorecard with specific fix recommendations.
When to use
Run this skill whenever a user:
- Uploads or references a skill they want reviewed
- Asks "is this skill good?" or "check my skill"
- Wants to validate before publishing/distributing
- Is debugging triggering, execution, or quality issues
- Wants to improve an existing skill
How it works
The review runs in three phases:
- Structural validation — file naming, folder layout, YAML correctness
- Content quality audit — description effectiveness, instruction clarity, progressive disclosure, patterns used
- Scorecard & recommendations — graded rubric across all dimensions with prioritized fixes
