Validate SKILL.md frontmatter by checking for mandatory name and description fields in the YAML header, then verifying proper Markdown formatting in the body to ensure full Agent Skills standard compliance.

Skills standard validation requires a SKILL.md file containing mandatory name and description fields within the YAML frontmatter, alongside operational instructions written with proper Markdown formatting in the body.

Test skill unit structure by validating the presence and content of the SKILL.md file, confirming the frontmatter includes name and description, and checking the Markdown body for formatting compliance.

Yes, skills standard validation checks both the YAML frontmatter for mandatory name and description fields and the Markdown body for proper formatting to confirm operational instructions are present.

SKILL.md validation fails when the frontmatter is missing mandatory name or description fields, or when the Markdown body contains improper formatting that violates the Agent Skills standard compliance requirements.

Yes, you can validate the skill unit structure without external dependencies, as the testing process only requires the SKILL.md file itself to check frontmatter fields and Markdown formatting.
