To create Copilot Agent Skills, set up a folder under .github/skills with a lowercase-hyphenated name, add a SKILL.md file containing YAML frontmatter, and write a detailed Markdown body following repository guidelines.

The YAML frontmatter requires name and description fields to comply with the Skill Open Standard. Optional fields like license can be included to provide additional metadata for repository-specific tasks and skill discoverability.

You validate skill readiness by checking frontmatter compliance, structuring the Markdown body with clear instructions, and organizing optional resources. Categorizing and keyword-indexing the skill improves discoverability within the repository.

The best way to ensure token efficiency is structuring the skill with a clear Markdown body containing instructions, examples, procedures, and references, while keeping the YAML frontmatter concise with only necessary fields.
