To validate YAML frontmatter, you can run a check that parses the root-level SKILL.md to ensure required fields like name and description are present and correctly formatted for skill activation.

The best way to enforce required metadata fields is to use a validator that detects missing or malformed metadata across all Skill Unit directories, preventing invalid skills from being activated.

Yes, you can check for missing fields in a CI pipeline by running a validation step that enforces standard formatting and flags missing name or description fields in SKILL.md frontmatter.

Skill Units may not be discovered or activated if the root-level SKILL.md contains missing or malformed frontmatter, specifically lacking the mandatory name and description fields required for consistent discovery.

Frontmatter validation detects malformed metadata by applying YAML parsing directly to the root-level SKILL.md, checking for the presence and structural correctness of the name and description fields across all directories.
