Meta-skill for authoring, modifying, or reviewing skills in this repository. Use when adding a new skill, splitting/renaming an existing one, changing a shared template, debugging a `make build` or `make lint` failure, or proposing a structural change to the skills directory. Codifies the skill.yml schema, required SKILL.md sections, the templates/ system, and the build/lint workflow. Not for using a skill — only for authoring one.
