## What it does

The command guides UI component creation step by step. It inspects your project setup first, checking for `.ui-design/`, detected frameworks such as React or Vue, and styling tools like Tailwind or CSS Modules. If no framework is found, it asks you to pick one manually.

Next, it asks one question at a time to lock down specifications. You define component complexity, prop interfaces, state management approach, slot compositions, and WCAG accessibility standards. The entire setup is saved to `.ui-design/components/{component_name}.json`.

Once configured, it scaffolds a component folder with the main file, TypeScript definitions, style sheets, unit tests, and barrel exports. The command will not write source files until every specification question receives an answer.

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add wshobson/agents
```
In the agent chat (not a shell):
```text
/plugin install ui-design@claude-code-workflows
```

2. **Manually: put the files in place**
- File: `.claude/commands/create-component.md` — Call it with /create-component. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/create-component.md` — Call it with /prompts:create-component. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/create-component.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/create-component.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/wshobson/agents/tree/HEAD/plugins/ui-design/commands/create-component.md

## When to use it
- Define props and TypeScript contracts before generating code
- Scaffold UI component folders with matching tests and styles
- Track design specifications in `.ui-design/` JSON manifests
- Configure state patterns and accessibility levels consistently

## Example prompts
- /create-component UserCard
- /create-component DataTable
- /create-component

# Create Component

Guided workflow for creating new UI components following established patterns and best practices.

## Pre-flight Checks

1. Check if `.ui-design/` directory exists:
   - If not: Create `.ui-design/` directory
   - Create `.ui-design/components/` subdirectory for component tracking

2. Detect project configuration:
   - Scan for framework (React, Vue, Svelte, Angular)
   - Scan for styling approach (CSS Modules, Tailwind, styled-components, etc.)
   - Check for existing component patterns in `src/components/` or similar
   - Load `.ui-design/design-system.json` if exists

3. Load project context:
   - Check for `conductor/tech-stack.md`
   - Check for existing component conventions

4. If no framework detected:

   ```
   I couldn't detect a UI framework. What are you using?

   1. React
   2. Vue 3
   3. Svelte
   4. Angular
   5. Vanilla JavaScript/HTML
   6. Other (specify)

   Enter number:
   ```

## Component Specification

**CRITICAL RULES:**

- Ask ONE question per turn
- Wait for user response before proceeding
- Build complete specification before generating code

### Q1: Component Name (if not provided)

```
What should this component be called?

Guidelines:
- Use PascalCase (e.g., UserCard, DataTable)
- Be descriptive but concise
- Avoid generic names like "Component" or "Widget"

Enter component name:
```

### Q2: Component Purpose

```
What is this component's primary purpose?

1. Display content (cards, lists, text blocks)
2. Collect input (forms, selects, toggles)
3. Navigation (menus, tabs, breadcrumbs)
4. Feedback (alerts, toasts, modals)
5. Layout (containers, grids, sections)
6. Data visualization (charts, graphs, indicators)
7. Other (describe)

Enter number or description:
```

### Q3: Component Complexity

```
What is the component's complexity level?

1. Simple - Single responsibility, minimal props, no internal state
2. Compound - Multiple parts, some internal state, few props
3. Complex - Multiple subcomponents, state management, many props
4. Composite - Orchestrates other components, significant logic

Enter number:
```

### Q4: Props/Inputs Specification

```
What props/inputs should this component accept?

For each prop, provide:
- Name (camelCase)
- Type (string, number, boolean, function, object, array)
- Required or optional
- Default value (if optional)

Example format:
title: string, required
variant: "primary" | "secondary", optional, default: "primary"
onClick: function, optional

Enter props (one per line, empty line when done):
```

### Q5: State Requirements

```
Does this component need internal state?

1. Stateless - Pure presentational, all data via props
2. Local state - Simple internal state (open/closed, hover, etc.)
3. Controlled - State managed by parent, component reports changes
4. Uncontrolled - Manages own state, exposes refs for parent access
5. Hybrid - Supports both controlled and uncontrolled modes

Enter number:
```

### Q6: Composition Pattern (if complexity > Simple)

```
How should child content be handled?

1. No children - Self-contained component
2. Simple children - Accepts children prop for content
3. Named slots - Multiple content areas (header, body, footer)
4. Compound components - Exports subcomponents (e.g., Card.Header, Card.Body)
5. Render props - Accepts render function for flexibility

Enter number:
```

### Q7: Accessibility Requirements

```
What accessibility features are needed?

1. Basic - Semantic HTML, aria-labels where needed
2. Keyboard navigation - Full keyboard support, focus management
3. Screen reader optimized - Live regions, announcements
4. Full WCAG AA - All applicable success criteria

Enter number:
```

### Q8: Styling Approach

```
How should this component be styled?

Detected: {detected_approach}

1. Use detected approach ({detected_approach})
