when: >
  Invoked when the user wants to create, manage, or maintain a plugin marketplace for
  Claude Code and/or GitHub Copilot CLI. Covers four operations: (a) audit and refactor
  a repository of skills/agents/hooks into a plugin marketplace layout, (b) adopt external
  plugins/skills/agents from outside sources, (c) update and maintain an existing
  marketplace.json and plugin manifests, (d) validate existing plugin manifests for naming,
  structure, and cross-tool compatibility. Also triggered implicitly when the user asks
  about distributing skills to a team, organizing loose skills into installable units, or
  setting up cross-tool distribution — even without saying "marketplace".
