repo-skill-authoring

Create a repo-local skill by defining a SKILL.md file under .agents/skills/<skill-name>/ with frontmatter containing name and description, following the repository's skill authoring standard. This ensures consistency and reduces maintenance overhead.

The canonical structure for repo-local skills requires placing a SKILL.md file with name and description frontmatter under .agents/skills/<skill-name>/. This standardization prevents teams from duplicating standards and creating inconsistent skills.

Setting up harness shims and entrypoints involves following the guidance provided by the repo-skill-authoring standard to ensure alignment with the repository's skill authoring standard. This maintains consistency across skill workflows.

A standard for repo-local skill authoring is needed because repo teams sometimes duplicate standards when creating skills, leading to inconsistency and maintenance overhead. Defining repo-local skill shapes, supported files, and governance facilitates maintenance and reuse.

This skill authoring standard specifically applies to creating, validating, and maintaining repo-local skills within the MetaMask Mobile codebase. While the canonical shape could be adapted, the guidance is tailored to MetaMask Mobile workflows.
