## What it does

The skill pushes your agent to look for something that already exists before building it. It fires when you ask for a table, form, modal, dashboard, auth page or animation, and when you ask outright whether a component exists for something. The search reaches registries outside your `components.json` — Magic UI, Aceternity, ReUI, Animate UI, DiceUI, Tailark, AI Elements and others.

Three paths, depending on what you have set up. With the official shadcn MCP running, the skill calls its tools: `search_items_in_registries`, `view_items_in_registries`, `get_item_examples_from_registries`, `get_add_command_for_items`. With a `components.json` but no MCP, it falls back to `npx shadcn@latest search`, `view` and `list`. No project yet? It recommends registries for your need and offers `npx shadcn@latest init`.

One catch worth knowing: the MCP only searches registries declared in `components.json`. For anything specialised you have to add that registry to the config first, otherwise the search never sees it. This complements the official `shadcn` skill rather than replacing it — discovery here, installation and project-aware work there.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add mattbx/shadcn-skills --skill shadcn-component-discovery -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/shadcn-component-discovery/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/shadcn-component-discovery/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add mattbx/shadcn-skills --skill shadcn-component-discovery -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/shadcn-component-discovery/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mattbx/shadcn-skills --skill shadcn-component-discovery -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/shadcn-component-discovery/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mattbx/shadcn-skills shadcn-component-discovery
```

2. **Manually: put the files in place**
- File: `.github/skills/shadcn-component-discovery/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mattbx/shadcn-skills --skill shadcn-component-discovery -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mattbx/shadcn-skills --path skills/shadcn-component-discovery
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/shadcn-component-discovery/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mattbx/shadcn-skills --skill shadcn-component-discovery -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mattbx/shadcn-skills/tree/HEAD/skills/shadcn-component-discovery/SKILL.md

## When to use it
- find a ready-made table instead of hand-rolling one
- pick a registry with the animations you need
- check whether a chat UI component already exists
- compare several options for the same UI pattern
- get the install command for the component you chose

## Example prompts
- find a component for a sortable table with filters
- is there something for an animated hero section?
- search registries for a date range picker

description: Discover shadcn-compatible components and registries across the entire ecosystem before writing any custom UI. Use PROACTIVELY before building tables, forms, modals, animations, dashboards, auth pages, or any UI component. Use when the user says "find a component for...", "is there something for...", "search registries", "what exists for...", or asks about shadcn blocks, Magic UI, Aceternity, ReUI, Animate UI, DiceUI, Tailark, AI Elements, or any other shadcn-compatible registry. Complements the official shadcn skill by surfacing registries beyond the user's configured `components.json` — use when exploring what's available to add, not just what's already installed.

# shadcn Component Discovery

Surface existing components from across the shadcn ecosystem — including registries the user hasn't configured yet — before spending effort on custom implementations.

## How This Complements the Official shadcn Skill

The official `shadcn` skill (shipped with CLI v4) searches the registries declared in the user's `components.json`. That's the right tool once the user has decided which registries to use.

This skill fills the *upstream* gap: ecosystem-wide awareness. It helps the user find and choose registries they may not yet have configured — Magic UI for animations, Aceternity for hero sections, AI Elements for chat interfaces, ElevenLabs UI for voice components, and so on. Use this skill for "what exists out there"; let the official skill handle "install this thing I know about."

When both skills apply, this one runs first (discovery), then the official skill takes over for installation and project-aware work.

## Core Principle

Search before building. Most UI needs have been solved in the shadcn ecosystem. The cost of a 10-second registry check is almost always less than custom-building something that already exists.

## When to Trigger

**Proactive triggers** (activate before writing any component code):

- User asks to build a table, form, modal, sidebar, dashboard, auth page, landing section, animation, carousel, chart, or any standard UI pattern
- User describes a feature that implies UI (e.g. "add user accounts management" → table; "let users pick a date range" → date picker)
- User mentions building something "like X" where X is a common pattern

**Explicit triggers** (user directly requests search):

- "Find a component for..."
- "Is there a shadcn component for..."
- "Search registries for..."
```
