Marketplace Dev
Turns a directory of Claude skills into a proper plugin marketplace with one-click installs and auto-updates. It reads your SKILL.md files, generates the .claude-plugin/marketplace.json conforming to Anthropic's spec, runs validation, and tests the actual installation flow before opening a PR. The skill encodes hard-won lessons from real marketplace development like schema traps (no $schema field allowed, metadata has exactly three valid keys, strict:false when there's no plugin.json) and the single-skill versus suite plugin decision. Use it when you have a skills repo and want users to install via `claude plugin marketplace add` instead of manual copying. Saves you from reading validator errors at 2am.
