name: component-transformer description: Orchestrates the migration of legacy MUI or generic components to the Northcote Curio design system. Specializes in "Refactor-on-Port" logic, ensuring visual transformation while preserving business state and behavioral integrity.

Component Transformer Skill

Migration Steps

1. The Audit (Discovery)

Use the token-orchestrator principles to scan the file for:

• ❌ Hardcoded colors (hex, rgb, rgba)
• ❌ Hardcoded spacing (padding, margin, gap in px)
• ❌ Hardcoded radii (4px, 8px, etc.)
• ❌ Generic fonts (Inter, Arial, System)
• ❌ Standard easing (ease-in-out)

2. The Context Selection

Determine if the component belongs in:

• Mode A (Gallery): For "Wonder" (Marketing, Profile Hero, Landing).
• Mode B (Laboratory): For "Rigor" (Parsing, Data, Settings, Editor).

3. The Transformation (Mapping)

Replace generic values with the Northcote Token Set:

• Colors: Map to primary-wattle, tertiary-waratah, parchment, etc.
• Typography: Inject the Federation Stack.
  • Wrap primary headers in banksia-composition.
  • Apply font-variation-settings for parametric weight (XTRA: 468).
• Physics: Replace linear transitions with ease-viscous or ease-settle.
• Morphology: Apply asymmetric border-radii (radius-pebble, etc.).

4. Behavioral Preservation

Ensure no business logic, event handlers, or state management is lost or altered during the visual upgrade.

5. Verification

• Generate unit tests using jest-test-scaffolder.
• Create a Storybook story using storybook-scaffolder.

Implementation Principles

• Anti-Slop: Reject any transformation that results in a "generic SaaS" look.
• Parametric: Engage variable font axes for interactive elements (e.g., GRAD hover).
• Layout-Safe: Prefer GRAD over wght for hover animations to prevent reflow.

Usage Example

"Transform Header.tsx to the Northcote Curio system. It should be in Gallery mode."
