SkillCheck

Overview

Validate SKILL.md files against the agentskills specification and Anthropic best practices. Catches structural errors, semantic contradictions, naming anti-patterns, and quality gaps in a single read-only pass.

When to Use This Skill

  • Use when user says "check skill", "skillcheck", or "validate SKILL.md"
  • Use when reviewing a skill before publishing to a marketplace
  • Use when debugging why a skill doesn't trigger correctly
  • Use when onboarding a team to skill authoring standards
  • Do NOT use for anti-slop detection, security scanning, or token analysis; use SkillCheck Pro for those

How It Works

Step 1: Parse

Read the target SKILL.md file and extract YAML frontmatter.
