Review Skill Format

Validate a SKILL.md file against the agentskills.io open standard. This skill checks YAML frontmatter completeness, required section presence, procedure step format (Expected/On failure blocks), line count limits, and registry synchronization. Use this before merging any new or modified skill.

When to Use

• A new skill has been authored and needs format validation before merge
• An existing skill has been modified and needs re-validation
• Performing a batch audit of all skills in a domain
• Verifying a skill created by the create-skill meta-skill
• Reviewing a contributor's skill submission in a pull request

Inputs

• Required: Path to the SKILL.md file (e.g., skills/setup-vault/SKILL.md)
• Optional: Strictness level (lenient or strict, default: strict)
• Optional: Whether to check registry sync (default: yes)
