name: storybook-integration description: > Skill for integrating Storybook with spec.md. Auto-generates Stories skeletons from Component API specifications. Use when working with Storybook, Stories, component specifications, or frontend component development. Covers CSF3 format, autodocs integration, Props-to-argTypes mapping, and component API templates. Essential for /think (Component API generation) and /code (Stories generation) commands. allowed-tools: Read, Write, Glob, Grep

Storybook Integration - Component API to Stories Generator

Overview

Skill for integrating Storybook with Claude Code workflow. Covers:

1. Component API Template - Component specification template added to spec.md
2. CSF3 Patterns - Component Story Format 3 best practices
3. Stories Generation - Auto-generate Stories skeletons from spec.md

When to Use This Skill

Automatic Triggers

Keywords that activate this skill:

• storybook, stories
• component api, component specification
• props, argTypes, variants
• csf, csf3, autodocs
• frontend component

Explicit Invocation

For guaranteed activation:

• "Apply storybook integration"
• "Generate stories from spec"
• "Add component API to spec.md"

Common Scenarios

• /think for frontend feature planning → Component API section added
• /code for component implementation → Stories skeleton generated
• Standardizing component specifications
• Integration with Storybook autodocs

Core Concepts

1. Component API Section in spec.md

Section added to spec.md when planning frontend features with /think.

Location: ### 4.x Component API: [ComponentName] inside ## 4. UI Specification

Contents:

• Props Interface (TypeScript)
• Variants (size, color, state)
• States (default, hover, disabled, loading)
• Usage Examples

2. Stories Generation

Auto-generated when /code is run and spec.md contains Component API section.

Output: [ComponentName].stories.tsx

Format: CSF3 + autodocs

3. Frontend Detection

Auto-detection from feature description:

function shouldGenerateComponentAPI(feature: string): boolean {
  const frontendKeywords = [
    /component/i,
    /ui/i,
    /frontend/i,
    /button/i,
    /form/i,
    /modal/i,
    /dialog/i,
    /card/i,
    /list/i,
    /table/i,
  ];

  const backendKeywords = [
    /api endpoint/i,
    /database/i,
    /server/i,
    /backend/i,
    /cli/i,
    /migration/i,
  ];

  const hasFrontend = frontendKeywords.some(kw => kw.test(feature));
  const hasBackend = backendKeywords.some(kw => kw.test(feature));

  return hasFrontend && !hasBackend;
}

Data Models

ComponentSpec

interface ComponentSpec {
  name: string;                    // Component name (PascalCase)
  description: string;             // Description
  props: PropDefinition[];         // Props definitions
  variants: VariantDefinition[];   // Variants
  examples: UsageExample[];        // Usage examples
}

interface PropDefinition {
  name: string;                    // Prop name
  type: string;                    // TypeScript type
  required: boolean;               // Is required
  defaultValue?: string;           // Default value
  description: string;             // Description
}

interface VariantDefinition {
  name: string;                    // Variant name (e.g., "size")
  options: string[];               // Options (e.g., ["sm", "md", "lg"])
  defaultOption: string;           // Default value
}

interface UsageExample {
  title: string;                   // Example title
  code: string;                    // JSX code
  description?: string;            // Description
}

Templates

Component API Template

See: [@./references/component-api-template.md]

CSF3 Patterns

See: [@./references/csf3-patterns.md]

Integration Points

With Commands

• /think - Adds Component API section when frontend feature detected
• /code - Generates Stories from Component API section

With Skills

• frontend-patterns - Integration with Container/Presentational patterns
• tdd-test-generation - Leverage Stories as tests

Integration Method

# In command YAML frontmatter
dependencies: [storybook-integration, frontend-patterns]

Workflow

/think → spec.md generation

/think "Add Button component"
    ↓
shouldGenerateComponentAPI("Add Button component")
    ↓ YES
Add Component API section to spec.md:
    ## 4.x Component API: Button
    ### Props
    ### Variants
    ### States
    ### Usage Examples

/code → Stories generation

/code
    ↓
Component API section in spec.md?
    ↓ YES
parseComponentSpec(specContent)
    ↓
Existing Stories file?
    ├─ YES → Show integration strategy (O/S/M/D)
    └─ NO  → Generate with generateStoryTemplate(spec)

Existing Stories Integration (EC-002)

Options when existing Stories file is found:

[O] Overwrite - Completely replace existing file
[S] Skip - Keep existing file, do not generate
[M] Merge (manual) - Show diff, integrate manually
[D] Diff only - Append only new Stories

Best Practices

Do's

• Explicitly type Props
• Cover all variant options
• Include practical code in Usage Examples
• Leverage autodocs for automatic documentation

Don'ts

• Don't include complex logic in Stories (use play function separately)
• Don't create Stories for all Props combinations (focus on representative ones)
• Avoid overusing decorators

Quick Start

1. Plan frontend feature

/think "Add Button component with primary/secondary variants"

→ Component API section auto-added to spec.md

2. Implement component

/code

→ Button.tsx and Button.stories.tsx generated

3. Verify in Storybook

npm run storybook

→ Props documentation auto-generated via autodocs
