bootstrap-skills-plugin-repo
Bootstrap or align a source-first Agent Skills repository with root `skills/`, repo-local discovery mirrors, maintainer docs, and clear Codex plugin-boundary wording. Use when creating a new skills repo or structurally aligning an existing one. Do not use this for narrow README-only, roadmap-only, or host-adapter design work.
