shadcn/ui Component Skill

Drives the shadcn/ui CLI and enforces shadcn-specific code rules when adding, fixing, styling, or composing components.

What it does

  • Injects live project context via npx shadcn@latest info --json (aliases, Tailwind version, isRSC, iconLibrary, base vs radix) so generated code matches your setup.
  • Enforces a workflow: search registries → docs <component> and fetch URLs → add → re-read and verify the added files.
  • Blocks classic shadcn mistakes: gap-* instead of space-y-*, size-* instead of w-10 h-10, FieldGroup + Field for forms, data-icon for button icons, semantic tokens only (bg-primary, text-muted-foreground).
  • Documents safe update flows: --dry-run / --diff merges that preserve local edits, and a reinstall / merge / skip decision tree for switching --preset codes.

Who it's for

  • React, Next.js, Vite, Astro, or React Router developers using shadcn/ui.
  • Anyone pulling blocks from third-party registries (@shadcn, @magicui, @tailark) who has to fix import aliases and icon libraries by hand.
  • Team leads who want consistent, accessible component composition.

Examples

  1. "Build a settings page" → composes Tabs + Card + FieldGroup using your real alias and icon library rather than guessing.
  2. "Add the shimmer button from @magicui" → confirms the registry, installs, then rewrites hardcoded @/components/ui/... imports to your project's alias.
  3. "Update the button component from upstream" → runs add button --dry-run, inspects --diff per file, and merges upstream changes while keeping your customizations.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the .agents/skills/shadcn folder from the GitHub repo molefrog/moi into my ~/.claude/skills/shadcn/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/molefrog/moi.git /tmp/moi && mkdir -p ~/.claude/skills && cp -r /tmp/moi/.agents/skills/shadcn ~/.claude/skills/shadcn

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repository: git clone https://github.com/molefrog/moi.git /tmp/moi
  3. Create the skills directory: mkdir -p ~/.claude/skills
  4. Copy the whole skill folder (including rules/ and cli.md): cp -r /tmp/moi/.agents/skills/shadcn ~/.claude/skills/shadcn
  5. Verify that ~/.claude/skills/shadcn/SKILL.md and the rules/ directory exist.
  6. Make sure Node.js with npm/pnpm/bun is installed and that your target project has a components.json file.
  7. Restart Claude Code; any shadcn-related request (e.g. "build a login form with shadcn") will trigger the skill automatically.
