Guidance for building Claude Code skills, agents, and plugins. The guidance skill answers authoring questions and, run with init, vendors the full guidance set into a repo as a path-scoped rule index so the right guidance surfaces while editing skill and agent files. Opt-in and dependency-free: installed on its own, not pulled in by the han meta-plugin.
