Manages shadcn components and projects — adding, searching, fixing, debugging, styling, and composing UI. Provides project context, component docs, and usage examples. Applies when working with shadcn/ui, component registries, presets, --preset codes, or any project with a components.json file. Also triggers for "shadcn init", "create an app with --preset", or "switch to --preset".
Tag meme assets and generate display titles by actual visual content, not filenames. Use when populating or updating `src/lib/memes-database.ts`, classifying meme images/GIFs, or generating search labels for meme libraries. Workflow uses Bun scripts, GIF frame sheets, alias previews to hide filenames, and Gemini CLI for visual tagging and title generation.
