What it does

Spec compliance is table stakes. skill-validator goes further: it checks that links actually resolve, flags files that shouldn't be in a skill directory, reports token counts so you can see how much of an agent's context window your skill will consume, analyzes content quality metrics, detects cross-language contamination, and offers LLM-as-judge scoring to evaluate skill quality across dimensions like clarity, actionability, and novelty. A spec-compliant skill that has broken links or a 60k-token reference file will technically pass the spec but perform poorly in practice.
