FAQPage Schema

How do I validate YAML frontmatter in a SKILL.md file?▼

YAML frontmatter validation involves checking skill unit files against the official skill definition to identify and flag missing mandatory metadata required for proper repository analysis and execution.

A skill unit fails discovery because missing mandatory YAML frontmatter prevents the repository analysis workflow from recognizing and properly executing the skill unit according to the official definition.

What happens when a configuration placeholder lacks essential metadata?▼

When a configuration placeholder lacks essential metadata, it remains non-functional and serves only as an example of an invalid skill unit that cannot be used or executed in validation workflows.

How do I check if my repository analysis flags missing frontmatter?▼

Repository analysis checks for missing frontmatter by scanning skill unit files and validating them against the official skill unit definition to flag any SKILL.md missing mandatory YAML metadata.

When do I need to validate skill unit definitions for proper execution?▼

You need to validate skill unit definitions during repository analysis workflows to ensure all SKILL.md files contain mandatory YAML frontmatter required for proper discovery and execution.
