Design Reference Transformer

Transform a complete design reference HTML file into a working Vibes app with TinyBase reactive data.

Core Principle

Preserve and adapt, don't interpret and recreate.

The design reference is source code to transform, not inspiration to interpret. When given a complete HTML file with styles, your job is to make minimal surgical changes to connect it to React/TinyBase—not to recreate it from your understanding of its aesthetic.

When to Use This Skill

Use this skill when:

• User provides a design.html, mockup, or static prototype file
• User says "match this design exactly" or "use this as a reference"
• User wants their existing HTML converted to a Vibes app
• A previous implementation didn't match the design reference

The Transformation is Mechanical

The conversion from design HTML to React/TinyBase is deterministic, not creative:

CSS requires NO changes. Copy the entire <style> block verbatim.

Workflow

Step 1: Read the Design Reference

# Read the design file completely
Read design.html

Note the structure:

• <style> block (copy verbatim)
• HTML structure (preserve exactly)
• Any vanilla JavaScript (will be replaced with React)

Step 2: Identify Dynamic Content

Ask: "What content comes from the database?"

Typical dynamic elements:

• List items that repeat (.map())
• Text that users enter (controlled inputs)
• Counts, totals, timestamps
• User-specific content

Everything else stays static.

Step 3: Create the React Component

function App() {
  // TinyBase hooks are globals — no imports, no initialization call needed
  const rowIds = useRowIds('items');
  const handleAdd = useAddRowCallback('items', (e) => ({
    text: '', type: 'item', created: Date.now()
  }));

  return (
    <>
      {/* CSS copied VERBATIM from design.html */}
      <style>{`
        /* Paste entire <style> block here unchanged */
      `}</style>

      {/* HTML structure preserved, only syntax converted */}
      {/* Dynamic content replaced with {expressions} */}
    </>
  );
}

Step 4: Handle Dark Mode Override (If Needed)

The Vibes template has dark mode support. If your design is light-only, add this CSS override:

/* Force light theme regardless of system preference */
html, body, #container, #container > div {
    background-color: var(--your-bg-color) !important;
}

Note: Avoid targeting [style*="position: fixed"] as this will style the VibesSwitch toggle button.

Step 4b: Scope CSS to Avoid VibesSwitch/VibesPanel Conflicts

The template includes a VibesSwitch toggle button and VibesPanel admin menu that sit outside your app container. Broad CSS selectors can accidentally style these components.

Watch for these problematic patterns:

If your design has global button/element styles:

1. Wrap your app content in a container with a class: <div className="app">...</div>
2. Scope broad rules: button { } → .app button { }
3. Or use #container which is the template's app root

The template already protects components with:

button[aria-controls="hidden-menu"] { background: transparent !important; }
#hidden-menu { /* menu-specific variable resets */ }

But defense-in-depth is better—scope your CSS to avoid conflicts.

Step 5: Assemble and Test

VIBES_ROOT="${CLAUDE_PLUGIN_ROOT:-$(dirname "$(dirname "${CLAUDE_SKILL_DIR}")")}"
bun "$VIBES_ROOT/scripts/assemble.js" app.jsx index.html

Open in browser and visually diff against the design reference. They should be pixel-identical except for dynamic content.

Anti-Patterns (DO NOT DO THESE)

Transformation Checklist

Before writing code, verify:

• Read the entire design.html file
• Identified all <style> blocks (will copy verbatim)
• Identified dynamic content (lists, inputs, user data)
• Identified vanilla JS functionality (will convert to React)
• Noted any custom fonts (add to imports if needed)
• Checked for dark/light theme assumptions

During transformation:

• CSS pasted unchanged (no "improvements")
• HTML structure preserved exactly
• Only syntax converted (class→className, etc.)
• Dynamic content uses {expressions} and .map()
• Vanilla JS replaced with React hooks and handlers
• Dark mode override added if design is light-only

After assembly:

• Visual comparison with design reference
• All interactive elements work
• Data persists on refresh
• No console errors
• VibesSwitch toggle (bottom-right) displays correctly with no background box
• VibesPanel menu opens when toggle is clicked
• Menu buttons are correctly styled (not inheriting app button styles)

Example: Static List → Dynamic List

Design HTML:

<ul class="item-list">
  <li class="item">First item</li>
  <li class="item">Second item</li>
</ul>

React with TinyBase:

const rowIds = useRowIds('items');

<ul className="item-list">
  {rowIds.map(id => (
    <ItemRow key={id} id={id} />
  ))}
</ul>

// Child component uses useCell for reactive per-row data
function ItemRow({ id }) {
  const text = useCell('items', id, 'text');
  return <li className="item">{text}</li>;
}

Note: Only the content changed. The classes, structure, and styling are identical.

Example: Static Form → Controlled Form

Design HTML:

<form>
  <input type="text" class="input" placeholder="Enter text...">
  <button class="btn">Submit</button>
</form>

React with TinyBase:

const [text, setText] = useState('');
const handleAdd = useAddRowCallback('items', () => ({
  text, type: 'item', created: Date.now()
}));

<form => { e.preventDefault(); handleAdd(); setText(''); }}>
  <input
    type="text"
    className="input"
    placeholder="Enter text..."
    value={text}
    => setText(e.target.value)}
  />
  <button type="submit" className="btn">Submit</button>
</form>

Note: Same structure, same classes, same placeholder. Only added React bindings.

Integration with Vibes Assembly

This skill produces an app.jsx that works with the standard Vibes assembly:

# In the working directory
VIBES_ROOT="${CLAUDE_PLUGIN_ROOT:-$(dirname "$(dirname "${CLAUDE_SKILL_DIR}")")}"
bun "$VIBES_ROOT/scripts/assemble.js" app.jsx index.html

The assembly script:

• Inserts your JSX into the Vibes template
• Handles OIDC authentication wrapper (via Pocket ID)
• Sets up import maps for React and TinyBase
• Configures sync URLs if present (auth is automatic via Pocket ID)
