 ## What it does
 
-Routes to one of two flows based on context: if no skill directory exists at the target path, it scaffolds the directory from annotated templates, fills in `SKILL.md` and supporting files, and validates the result. If an existing skill directory and improvement signals are both present, it groups those signals by root cause and applies targeted edits, then re-validates.

In both flows, if the skill lives inside a plugin directory, bumps the plugin version in both manifests.
