To structure an open format agent skill, create a skill directory with a SKILL.md file, add a concise body, and link any reference files. This enforces frontmatter constraints and supports optional scripts, references, and assets.

The open format specification for skill creation is a standard that guides authors to structure and validate agent skills. It enforces frontmatter constraints, defines directory patterns for references and rules, and links to evaluation references.

When authoring a SKILL.md file, configure frontmatter by adhering to enforced constraints and add references by linking files within the skill directory. This structure supports optional scripts and assets for the agent skill.

Yes, the skill creation workflow supports cross-model evaluation and MCP tool references. It includes built-in guidance for evaluation, cross-model testing, and linking to a quality checklist to prepare skills for different models.

Frontmatter constraints for open format agent skills are enforced rules applied during skill creation to ensure proper structuring. These constraints validate the SKILL.md file and reduce ambiguity before shipping the skill.
