What this skill does

# Design to Code

Convert visual designs into production-ready React components using a four-stage pipeline: Extract, Match, Adapt, Render.

```bash
/ork:design-to-code screenshot of hero section    # From description
/ork:design-to-code /tmp/mockup.png               # From screenshot
/ork:design-to-code https://example.com/pricing    # From URL
```

## Argument Resolution

```python
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

```python
# 1. Create main task IMMEDIATELY
TaskCreate(subject="Design to code: {INPUT}", description="Four-stage pipeline: extract, match, adapt, render", activeForm="Converting design to code")

# 2. Create subtasks for each stage
TaskCreate(subject="Extract design context", activeForm="Extracting design context")               # id=2
TaskCreate(subject="Match components (Storybook-first)", activeForm="Matching components")         # id=3
TaskCreate(subject="Adapt to project tokens and conventions", activeForm="Adapting to project")    # id=4
TaskCreate(subject="Register in json-render catalog", activeForm="Registering in catalog")         # id=5
TaskCreate(subject="Verify with Storybook self-healing", activeForm="Verifying component")         # id=6

# 3. Set dependencies for sequential stages
TaskUpdate(taskId="3", addBlockedBy=["2"])  # Match needs extracted design context
TaskUpdate(taskId="4", addBlockedBy=["3"])  # Adapt needs matched components
TaskUpdate(taskId="5", addBlockedBy=["4"])  # Render needs adapted component
TaskUpdate(taskId="6", addBlockedBy=["5"])  # Verify needs rendered component

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

# Detect shadcn/ui style (v4 style system)
Glob("**/components.json")
# Read → style field (e.g., "radix-luma", "base-nova")
# Determines class names: Luma=rounded-4xl, Nova=compact, Lyra=sharp
# Store: SHADCN_STYLE for Stage 2 filtering + Stage 3 adaptation
```

## Stage 1: Extract Design Context

**If stitch MCP is available:**
```python
# Official Stitch MCP tools (stitch.withgoogle.com/docs/mcp):
#   - build_site(prompt)          → multi-screen app, up to 5 interconnected screens
#   - get_screen_code(screenId)   → returns React/HTML for a generated screen
#   - get_screen_image(screenId)  → returns PNG of a generated screen
#
# For screenshot/URL input:
#   1. Upload screenshot to Stitch (or pass URL)
#   2. Call build_site() with the visual as context
#   3. get_screen_code() to retrieve the React/HTML output
#
# For description input:
#   1. Call build_site(prompt=<description>)
#   2. get_screen_code() / get_screen_image() to retrieve the result
#
# DESIGN.md import (Stitch Pro, Mar 2026+):
#   Stitch can also import a natural-language DESIGN.md file to regenerate
#   a layout without starting from scratch. Useful for iterative edits.
```

**If stitch MCP is NOT available (fallback):**
```python
# 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
```

> **Resolution budget (Opus 4.8 / CC 2.1.111+):** Mockups up to **2,576 px on the long edge** (~3.75 MP, 3× prior ceiling) produce better component boundaries and spacing extraction. Full-page desktop mockups at native resolution are now in-budget; previously they had to be resized down and lost fine detail. Only downscale inputs exceeding 2,576 px.

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):**
```python
# 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):**
```python
# 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
# If SHADCN_STYLE detected, prefer components matching style's visual language
# (e.g., Luma → rounded/pill-shaped, Nova → compact/dense, Lyra → sharp/boxy)
```

**Priority 3 — Filesystem fallback (if no MCP servers available):**
```python
# 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:
```python
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:

1. **Apply project tokens** — Replace hardcoded colors/spacing with project's design tokens
2. **Apply shadcn style classes** — If `SHADCN_STYLE` detected, use style-correct class names:
   - Luma: `rounded-4xl` buttons/cards, `shadow-md` + `ring-1 ring-foreground/5`, `gap-6 py-6`
