Validation Checklist

For each skill directory, verify:

Spec Compliance (agentskills.io)

Best Practices (Claude Code)

Body length	Under 500 lines
References one-level deep	No nested reference chains
Links are markdown	Use `[text](path)` not bare filenames

Concise	Only add context Claude doesn't already have
