cursor/plugins — reverse-engineered prompt

Build me a Cursor plugins repository that feels like an official marketplace for developer workflow plugins.

I want a root marketplace manifest that lists all available plugins, and each plugin should live in its own folder with its own manifest, README, changelog, license, rules, skills, and any MCP setup it needs. Include practical plugins for things like creating and validating new plugins, keeping AGENTS.md memory updated from transcripts, scanning repo compatibility, designing agent friendly CLIs, turning PR reviews and docs into Cursor Canvases, using the Cursor SDK, running parallel agent workflows, and doing deep branch reviews.

Make it easy for someone to add a new plugin without guessing the structure. Include clear examples, validation scripts, and simple docs so a developer can clone the repo, inspect a plugin, and understand how to publish or test it. Use TypeScript where it makes sense. Look up current Cursor plugin docs online if you need to.
