Shadcn UI & ShadcnBlocks Integration

This skill enables building polished frontends using shadcn/ui components and premium ShadcnBlocks templates. Its primary capability is intelligently recommending the best block or component for any UI need — not just the right category, but the right variant within that category — then handling setup and installation.

When to Use

Activate this skill when:

Creating a new frontend, landing page, marketing site, or app UI
The project uses or should use React/Next.js with Tailwind CSS
Pre-built UI sections (hero, pricing, features, testimonials, etc.) would accelerate development
The user needs a specific UI element (form, chart, dialog, navigation, etc.)
The user mentions shadcn, shadcn/ui, shadcnblocks, or Tailwind-based UI components

Blocks vs Components

	Blocks	Components
What	Full page sections	Reusable UI elements
Size	Hero, pricing, footer, etc.	Buttons, inputs, dialogs, etc.
Count	1,338 across 71 categories	1,189 across 60+ groups
Access	Premium (API key required)	Free
Install	`@shadcnblocks/<name><number>`	`@shadcnblocks/<type>-<style>-<number>`

Use blocks to compose full page layouts from pre-built sections. Use components for individual UI elements inside custom code.

Intelligent Block Selection

The 0-2 Question Rule

When recommending blocks, follow this progressive disclosure flow:

0 questions: The user's request is specific enough to match directly (e.g., "add a hero with email capture form" → match on cta_pattern: form_capture)
1 question: The section is clear but the style/layout is ambiguous (e.g., "add a feature section" → ask about layout preference)
2 questions max: Both section and style are unclear (e.g., "add a section to show our product" → ask section type, then style)

Never ask more than 2 questions. If still ambiguous, pick the best 2-3 and explain the tradeoffs.

Decision Flow: Infer → Ask → Shortlist

Step 1 — Infer from the request (always do this first)

Extract as many constraints as possible before asking anything:

Section type: hero, feature, pricing, testimonial, cta, faq, navbar, footer, contact, stats
Goal keywords: "signup" → convert/capture_leads, "trust" → trust, "compare plans" → compare
Layout hints: "grid" → grid_cards, "side by side" → split, "accordion" → accordion interaction
Tone hints: "clean" → minimal, "bold" → bold, "professional" → enterprise
Media hints: "with screenshots" → screenshot media, "video" → video media
Density hints: "simple" → minimal density, "detailed" → rich density

Step 2 — Ask targeted questions (only if needed)

Use AskUserQuestion for structured multiple-choice refinement. Consult references/block-index.md → selection_prompts for the pre-defined questions and options per section.

Sections with pre-defined prompts: hero, feature, pricing, testimonial, cta, faq, navbar, footer, contact, stats.

Example for a feature section request:

AskUserQuestion:
  question: "How do you want to showcase your features?"
  options:
    - "Card grid (3-4 columns with icons)" — Classic feature grid with icon + description per card
    - "Alternating image + text rows" — Deep-dive with large visuals, great for product tours
    - "Bento / asymmetric grid" — Modern editorial layout with mixed-size cards
    - "Simple icon list or checklist" — Compact, scannable benefit list

If AskUserQuestion is unavailable, ask the same question inline with numbered options.

Step 3 — Match tags and return 2-3 best picks

Map the user's answer to tag filters, then match against references/block-index.md entries. Return exactly 2-3 recommendations in this format:

Here are the best matches for your [section type]:

1. **[block-id]** — [1-line "why this one"]
   Layout: [layout] · Tone: [tone] · [key differentiator]

2. **[block-id]** — [1-line "why this one"]
   Layout: [layout] · Tone: [tone] · [key differentiator]

3. **[block-id]** — [1-line "why this one"]
   Layout: [layout] · Tone: [tone] · [key differentiator]

Which one works best? I'll install it and set it up.

After the user picks, provide the install command and compose it into the page.

Tag Dimensions Used for Matching

These are the key dimensions from references/block-index.md used to differentiate blocks:

Dimension	What it tells you	Example values
`layout`	Visual arrangement	centered, split_right_media, grid_cards, bento, alternating
`tone`	Aesthetic feel	minimal, modern, bold, enterprise, elegant, playful
`goal`	Business purpose	awareness, explain, trust, convert, capture_leads, compare
`cta_pattern`	Action type	single_primary, primary_secondary, form_capture, multi_action
`media`	Visual content	screenshot, illustration, video, icons, avatars, logos
`interaction`	Dynamic behavior	static, accordion, tabs, carousel, toggle, hover
`items_count`	Number of items displayed	few, moderate, many
`content_density`	How much content	minimal, standard, rich
`complexity`	Implementation effort	low, medium, high

When to Use Which Reference

Scenario	Use
Recommending best-fit blocks (default)	`references/block-index.md` — tagged picks with selection prompts
User wants a specific numbered variant	`references/block-catalog.md` — full catalog with all variant numbers
Section not in block-index (e.g., blog, gallery)	`references/block-catalog.md` — fall back to category defaults
User wants to browse all options	Direct to https://shadcnblocks.com/explorer/blocks
Need an individual UI element	`references/component-catalog.md` — free components

Core Workflow

1. Ensure Project Foundation

Verify the project has shadcn/ui initialized. If not:

npx shadcn@latest init

This creates components.json in the project root.

2. Configure ShadcnBlocks Registry

Check if components.json already has the @shadcnblocks registry. If not, run:

bash "${CLAUDE_PLUGIN_ROOT}/skills/shadcn-ui/scripts/setup-shadcnblocks.sh" .

This adds the @shadcnblocks registry to components.json and sets SHADCNBLOCKS_API_KEY in .env.

If the script can't run (e.g., jq missing), configure manually:

Add to .env: SHADCNBLOCKS_API_KEY=<key>
Add registry to components.json:

{
  "registries": {
    "@shadcnblocks": {
      "url": "https://shadcnblocks.com/r/{name}",
      "headers": {
        "Authorization": "Bearer ${SHADCNBLOCKS_API_KEY}"
      }
    }
  }
}

3. Select and Install Blocks

Use the intelligent selection flow (above) to recommend the best blocks, then install:

# Blocks (full page sections)
npx shadcn add @shadcnblocks/hero125
npx shadcn add @shadcnblocks/pricing3

# Components (UI elements)
npx shadcn add @shadcnblocks/accordion-standard-1
npx shadcn add @shadcnblocks/file-upload-standard-1

4. Compose the Page

Import and compose blocks in the page layout:

import { Navbar1 } from "@/components/navbar1";
import { Hero125 } from "@/components/hero125";
import { Feature3 } from "@/components/feature3";
import { Footer1 } from "@/components/footer1";

export default function LandingPage() {
  r

# Shadcn UI & ShadcnBlocks Integration

This skill enables building polished frontends using [shadcn/ui](https://ui.shadcn.com/) components and premium [ShadcnBlocks](https://shadcnblocks.com/) templates. Its primary capability is **intelligently recommending the best block or component** for any UI need — not just the right category, but the right *variant* within that category — then handling setup and installation.

## When to Use

Activate this skill when:
- Creating a new frontend, landing page, marketing site, or app UI
- The project uses or should use React/Next.js with Tailwind CSS
- Pre-built UI sections (hero, pricing, features, testimonials, etc.) would accelerate development
- The user needs a specific UI element (form, chart, dialog, navigation, etc.)
- The user mentions shadcn, shadcn/ui, shadcnblocks, or Tailwind-based UI components

## Blocks vs Components

| | Blocks | Components |
|---|--------|------------|
| **What** | Full page sections | Reusable UI elements |
| **Size** | Hero, pricing, footer, etc. | Buttons, inputs, dialogs, etc. |
| **Count** | 1,338 across 71 categories | 1,189 across 60+ groups |
| **Access** | Premium (API key required) | Free |
| **Install** | `@shadcnblocks/<name><number>` | `@shadcnblocks/<type>-<style>-<number>` |

**Use blocks** to compose full page layouts from pre-built sections.
**Use components** for individual UI elements inside custom code.

## Intelligent Block Selection

### The 0-2 Question Rule

When recommending blocks, follow this progressive disclosure flow:

- **0 questions**: The user's request is specific enough to match directly (e.g., "add a hero with email capture form" → match on `cta_pattern: form_capture`)
- **1 question**: The section is clear but the style/layout is ambiguous (e.g., "add a feature section" → ask about layout preference)
- **2 questions max**: Both section and style are unclear (e.g., "add a section to show our product" → ask section type, then style)

**Never ask more than 2 questions.** If still ambiguous, pick the best 2-3 and explain the tradeoffs.

### Decision Flow: Infer → Ask → Shortlist

**Step 1 — Infer from the request (always do this first)**

Extract as many constraints as possible before asking anything:
- **Section type**: hero, feature, pricing, testimonial, cta, faq, navbar, footer, contact, stats
- **Goal keywords**: "signup" → convert/capture_leads, "trust" → trust, "compare plans" → compare
- **Layout hints**: "grid" → grid_cards, "side by side" → split, "accordion" → accordion interaction
- **Tone hints**: "clean" → minimal, "bold" → bold, "professional" → enterprise
- **Media hints**: "with screenshots" → screenshot media, "video" → video media
- **Density hints**: "simple" → minimal density, "detailed" → rich density

**Step 2 — Ask targeted questions (only if needed)**

Use `AskUserQuestion` for structured multiple-choice refinement. Consult `references/block-index.md` → `selection_prompts` for the pre-defined questions and options per section.

**Sections with pre-defined prompts:** hero, feature, pricing, testimonial, cta, faq, navbar, footer, contact, stats.

Example for a feature section request:

```
AskUserQuestion:
  question: "How do you want to showcase your features?"
  options:
    - "Card grid (3-4 columns with icons)" — Classic feature grid with icon + description per card
    - "Alternating image + text rows" — Deep-dive with large visuals, great for product tours
    - "Bento / asymmetric grid" — Modern editorial layout with mixed-size cards
    - "Simple icon list or checklist" — Compact, scannable benefit list
```

If `AskUserQuestion` is unavailable, ask the same question inline with numbered options.

**Step 3 — Match tags and return 2-3 best picks**

Map the user's answer to tag filters, then match against `references/block-index.md` entries. Return exactly **2-3 recommendations** in this format:

```
Here are the best matches for your [section type]:

1. **[block-id]** — [1-line "why this one"]
   Layout: [layout] · Tone: [tone] · [key differentiator]

2. **[block-id]** — [1-line "why this one"]
   Layout: [layout] · Tone: [tone] · [key differentiator]

3. **[block-id]** — [1-line "why this one"]
   Layout: [layout] · Tone: [tone] · [key differentiator]

Which one works best? I'll install it and set it up.
```

After the user picks, provide the install command and compose it into the page.

### Tag Dimensions Used for Matching

These are the key dimensions from `references/block-index.md` used to differentiate blocks:

| Dimension | What it tells you | Example values |
|-----------|-------------------|----------------|
| `layout` | Visual arrangement | centered, split_right_media, grid_cards, bento, alternating |
| `tone` | Aesthetic feel | minimal, modern, bold, enterprise, elegant, playful |
| `goal` | Business purpose | awareness, explain, trust, convert, capture_leads, compare |
| `cta_pattern` | Action type | single_primary, primary_secondary, form_capture, multi_action |
| `media` | Visual content | screenshot, illustration, video, icons, avatars, logos |
| `interaction` | Dynamic behavior | static, accordion, tabs, carousel, toggle, hover |
| `items_count` | Number of items displayed | few, moderate, many |
| `content_density` | How much content | minimal, standard, rich |
| `complexity` | Implementation effort | low, medium, high |

## Core Workflow

### 1. Ensure Project Foundation

Verify the project has shadcn/ui initialized. If not:

```bash
npx shadcn@latest init
```

This creates `components.json` in the project root.

### 2. Configure ShadcnBlocks Registry

Check if `components.json` already has the `@shadcnblocks` registry. If not, run:

```bash
bash "${CLAUDE_PLUGIN_ROOT}/skills/shadcn-ui/scripts/setup-shadcnblocks.sh" .
```

This adds the `@shadcnblocks` registry to `components.json` and sets `SHADCNBLOCKS_API_KEY` in `.env`.

If the script can't run (e.g., `jq` missing), configure manually:

1. Add to `.env`: `SHADCNBLOCKS_API_KEY=<key>`
2. Add registry to `components.json`:
```json
{
  "registries": {
