Argument Resolution

INPUT = ""  # Full argument string
# Detect input type:
# - Starts with "/" or "~" or contains ".png"/".jpg" → screenshot file path
# - Starts with "http" → URL to screenshot or live page
# - Otherwise → natural language description

Step 0: Detect Input Type and Project Context

TaskCreate(subject="Design to code: {INPUT}", description="Four-stage pipeline: extract, match, adapt, render")

# Detect project's design system
Glob("**/tailwind.config.*")
Glob("**/tokens.css")
Glob("**/.tokens.json")
# Read existing tokens if found → used in Stage 3

Stage 1: Extract Design Context

If stitch MCP is available:

# For screenshot/URL input:
# Use official Stitch MCP tools to extract design HTML and context
# Tools: get_screen, list_screens, get_project

# For description input:
# generate_screen_from_text to create design, then get_screen to extract

If stitch MCP is NOT available (fallback):

# For screenshot: Read the image file directly (Claude is multimodal)
# Analyze layout, colors, typography, spacing from the image
# For URL: WebFetch the page, extract HTML structure
# For description: Skip extraction, proceed to Stage 2 with description

Extract and produce:

Color palette (hex/oklch values)
Typography (font families, sizes, weights)
Spacing patterns (padding, margins, gaps)
Component structure (headers, cards, buttons, etc.)
Layout pattern (grid, flex, sidebar, etc.)

Stage 2: Match Components (Storybook-First)

Priority 1 — Check project's own Storybook (if storybook-mcp available):

# Search the project's existing component library first
inventory = list-all-documentation()  # Full component + docs manifest
for component in inventory.components:
    if component matches extracted_description:
        details = get-documentation(id=component.id)
        # Returns: props schema, stories, usage patterns
        # → Existing component found — skip external search

Priority 2 — Search 21st.dev (if no Storybook match and 21st-dev-magic available):

# Search 21st.dev for matching components
# Use the component descriptions from Stage 1
# Example: "animated pricing table with toggle"
# Filter: React, Tailwind CSS, shadcn/ui compatible

Priority 3 — Filesystem fallback (if no MCP servers available):

# Search for components in the project's existing codebase
Grep(pattern="export.*function|export.*const", glob="**/*.tsx")
# Check for shadcn/ui components
Glob("**/components/ui/*.tsx")
# Generate from scratch if no matches found

Present matches to user:

AskUserQuestion(questions=[{
  "question": "Which component approach for {component_name}?",
  "header": "Component",
  "options": [
    {"label": "Reuse from Storybook", "description": "{existing_component} — props: {prop_list}"},
    {"label": "Use 21st.dev match", "description": "{matched_component_name} — {match_score}% match"},
    {"label": "Adapt from codebase", "description": "Modify existing {existing_component}"},
    {"label": "Generate from scratch", "description": "Build new component from extracted design"}
  ],
  "multiSelect": false
}])

Stage 3: Adapt to Project

Merge the extracted design context with matched/generated components:

Apply project tokens — Replace hardcoded colors/spacing with project's design tokens
Match naming conventions — Follow project's component naming patterns
Add TypeScript types — Full type safety with Zod validation for any data props
Include tests — MSW handlers for API-backed components, render tests for static
Responsive — Mobile-first with breakpoints matching project's system

Output Structure

src/components/
  └── {ComponentName}/
      ├── {ComponentName}.tsx       # Main component
      ├── {ComponentName}.test.tsx  # Tests
      └── index.ts                 # Barrel export

Stage 4: Register in json-render Catalog

After ADAPT produces a working React component, register it as a json-render catalog entry for multi-surface reuse.

Generate Zod schema — Derive a Zod schema from the component's TypeScript props
Add catalog entry — Register in the project's defineCatalog() call with props schema and children declaration
Verify rendering — Confirm the component renders correctly through <Render catalog={catalog} /> path

import { z } from 'zod'

// Zod schema derived from {ComponentName}Props
const componentSchema = z.object({
  title: z.string().max(100),
  variant: z.enum(['default', 'featured']).default('default'),
  // ... props from the adapted component
})

// Add to project catalog
import { defineCatalog, mergeCatalogs } from '@json-render/core'
import { existingCatalog } from './catalog'

export const catalog = mergeCatalogs(existingCatalog, {
  {ComponentName}: {
    props: componentSchema,
    children: true, // or false for leaf components
  },
})

Enables: same component output to PDF, email, video, or MCP response — no reimplementation needed.

Skip condition: If the project has no json-render dependency or catalog, inform the user and skip catalog registration. The component from Stage 3 is still fully usable standalone.

Stage 4b: Self-Healing Verification (if storybook-mcp available)

After generating the component, verify it with Storybook MCP:

# 1. Write CSF3 story for the new component
Write("src/components/{Name}/{Name}.stories.tsx", story_code)

# 2. Run tests via MCP (component + a11y)
results = run-story-tests(
    stories=[{ "storyId": "{name}--default" }],
    a11y=True
)

# 3. Handle failures — self-heal up to 3 attempts
if not results.all_passed:
    for failure in results.failures:
        # Read violation details, fix the component
        Edit("src/components/{Name}/{Name}.tsx", fix)
    # Re-run failing tests
    results = run-story-tests(stories=[...], a11y=True)

# 4. Preview — embed live story in chat for user confirmation
previews = preview-stories(stories=[
    { "absoluteStoryPath": "src/components/{Name}/{Name}.stories.tsx",
      "exportName": "Default" }
])
# Include preview URLs in response for visual confirmation

Skip condition: If storybook-mcp is not available, skip verification. The component is still usable — just not auto-verified.

Graceful Degradation

| stitch | 21st-dev-magic | storybook-mcp | Behavior | |--------|----------------|---------------|----------| | Available | Available | Available | Full pipeline: extract + Storybook-first match + adapt + render + self-heal verify | | Available | Available | Unavailable | Extract + 21st.dev match + adapt + render (no verification) | | Available | Unavailable | Available | Extract + Storybook match + adapt + verify | | Unavailable | Available | Available | Description-based search + Storybook check + adapt + verify | | Unavailable | Unavailable | Available | Filesystem search + Storybook verify only | | Unavailable | Unavailable | Unavailable | Manual analysis + generate from scratch (still works) |

The skill ALWAYS produces output regardless of MCP availability. Storybook MCP adds component reuse (Stage 2) and self-healing verification (Stage 4b) — skipping them still yields a working component.

Anti-Patterns

NEVER output components with hardcoded colors — use design tokens
NEVER skip TypeScript types — all props must be typed
NEVER generate without checking existing project patterns first
NEVER ignore the project's existing component library structure
