# Component Search

Search 21st.dev's registry of production-ready React components. Returns ranked results with code, previews, and install instructions.

```bash
/ork:component-search animated pricing table
/ork:component-search sidebar with collapsible sections
/ork:component-search dark mode toggle switch
```

## How It Works

```
Query: "animated pricing table with monthly/annual toggle"

## Step 0: Parse Query

```python
QUERY = ""  # Component description

# 1. Create main task IMMEDIATELY
TaskCreate(subject="Component search: {QUERY}", description="Search 21st.dev registry", activeForm="Searching for {QUERY}")

# 2. Create subtasks for each phase
TaskCreate(subject="Parse query and detect project context", activeForm="Detecting project context")  # id=2
TaskCreate(subject="Search component registry", activeForm="Searching registry")                      # id=3
TaskCreate(subject="Present and deliver results", activeForm="Presenting results")                    # id=4

# 3. Set dependencies for sequential phases
TaskUpdate(taskId="3", addBlockedBy=["2"])  # Search needs project context first
TaskUpdate(taskId="4", addBlockedBy=["3"])  # Results need search done

# 4. Before starting each task, verify it's unblocked
task = TaskGet(taskId="2")  # Verify blockedBy is empty

# 5. Update status as you progress
TaskUpdate(taskId="2", status="in_progress")  # When starting
TaskUpdate(taskId="2", status="completed")    # When done — repeat for each subtask

# Detect project context for framework filtering
Glob("**/package.json")
# Read to determine: React version, Tailwind, shadcn/ui, styling approach

# Detect shadcn/ui style for result ranking
Glob("**/components.json")
# Read → "style" field (e.g., "radix-luma", "base-nova")
# Used to prefer components matching the project's visual language
```

## Step 1: Search Registry

**If 21st-dev-magic MCP is available:**
```python
# Use MCP tools to search the 21st.dev component registry
# Pass the natural language query
# The MCP handles semantic search and ranking
```

**If 21st-dev-magic is NOT available (fallback):**
```python
# Fallback to web search
WebSearch("site:21st.dev {QUERY} React component")
# Or browse the registry
WebFetch("https://21st.dev", "Search for: {QUERY}")
```

**Alternative generation path — v0.app MCP (2026):**
When the registry doesn't have a matching component, fall back to AI
generation via the v0.app MCP server rather than WebFetch scraping:

```python
# If @vercel/v0-mcp is available
# v0.app generates from the same query and can pin to shadcn style
# (e.g., luma / nova / lyra) via `shadcn apply` after download.
```

This is a **generation** path, not a registry search — results will not
have view counts or stars. Prefer registry search when possible so you
get battle-tested components; use v0.app only when the registry misses.

## Step 2: Present Results

Show top 3 matches with:
- Component name and description
- Match relevance score
- Popularity (views/bookmarks)
- Framework compatibility
- Preview (if available)
- Install command

```python
AskUserQuestion(questions=[{
  "question": "Which component to use?",
  "header": "Component",
  "options": [
    {"label": "{name_1} (Recommended)", "description": "{desc_1} — {views_1} views"},
    {"label": "{name_2}", "description": "{desc_2} — {views_2} views"},
    {"label": "{name_3}", "description": "{desc_3} — {views_3} views"},
    {"label": "None — generate from scratch", "description": "Build a custom component instead"}
  ],
  "multiSelect": false
}])
```

## Step 3: Deliver Component

For the selected component:
1. Show the full source code
2. List dependencies (`npm install` commands)
3. Note any required peer dependencies (Radix, Motion, etc.)
4. Highlight customization points (props, tokens, slots)

## Framework Compatibility

| Project Stack | Search Filter | Notes |
|--------------|---------------|-------|
| React + Tailwind | Default — best coverage | Most 21st.dev components |
| React + CSS Modules | Filter non-Tailwind | Fewer results |
| Next.js App Router | Prefer RSC-compatible | Check "use client" directives |
| Vue / Svelte | Not supported | 21st.dev is React-only |
| shadcn/ui style | Match visual language | Luma→rounded/pill, Nova→compact, Lyra→sharp |

**shadcn v4 style awareness:** When `components.json` has a style (e.g., `"radix-luma"`), prefer components whose visual language matches — rounded pill shapes for Luma, dense layouts for Nova/Mira, sharp edges for Lyra. Components can be adapted post-install, but a closer match reduces customization work.
