SKILL.md is the primary file in a skill directory. It combines YAML frontmatter for metadata with a Markdown body for instructions that guide the model or agent during execution.
Frontmatter Fields
The YAML frontmatter defines the skill’s metadata:
Markdown Body
The body after the frontmatter contains instructions that are injected into the model or agent prompt at execution time. Write clear, specific instructions for the extraction or analysis task.
Example: Image Analysis Skill
Example: Video Analysis Skill
Write instructions as if you’re briefing an expert analyst. Be specific about what to look for, how to classify it, and what format to use for the output.
