To validate skill packaging using a CLI, run the validator against a minimal SKILL.md file to exercise frontmatter parsing and test optional references directory handling. This ensures parsing and packaging tooling correctly read mandatory fields.

Frontmatter validation for skill definitions is the process of checking the basic metadata fields in a SKILL.md file to ensure they meet required structural standards. It exercises parsing logic to confirm mandatory name and description fields are present.

To test a skill lifecycle end-to-end, apply a minimal well-formed example to automated test scenarios that import a basic SKILL.md and an optional references folder. This validates both the packaging and validation flows without external dependencies.

No, you do not need external dependencies to test skill parsing. The validation uses a minimal well-formed example with a SKILL.md file and an optional references directory to test content handling independently.

The best way to check SKILL.md structure correctness is to run an automated validation test that exercises the frontmatter fields and content structure. This confirms the skill definition meets packaging requirements.

Skill packaging fails frontmatter validation when the SKILL.md file is missing mandatory fields like name or description, or when the content structure does not meet the basic parsing requirements expected by the tooling.
