description

Reverse-engineering a Sketch file (or Figma export with similar shape) into pixel-perfect React + CSS — the iteration mental model, tree reconstruction, layout inference algorithms, geometry math, visual-regression diffing, and the style/typography/path conversions that make "improvement without regression" enforceable. Trigger even if the user doesn't explicitly mention "algorithms" but is converting a design source into web code, building a design-to-code pipeline, or struggling to make incremental fidelity improvements without breaking previously-converted output.

dot-skills Design-to-React Conversion Best Practices

The reverse-engineering pipeline that converts Sketch files into pixel-perfect React + CSS, with regression-safe iteration as the load-bearing constraint. The skill is organized around the cascade effect of design-to-code conversion: a wrong call in stage N corrupts every output from stage N+1 onward, so categories are ordered by how much downstream they own.

The user's primary requirement — "each improvement doesn't cause regressions" — is enforceable only if the iteration loop, the layer tree, and the layout solver are correct before you start polishing styles. Read the rules in priority order.

When to Apply

• Building a converter that ingests a .sketch file (or equivalent design source) and emits React + CSS
• Iterating on an existing converter where each improvement risks breaking other components
• Diagnosing why a converted component "almost matches" the design but visual-regression fails
• Designing the snapshot-gate / baseline strategy for a design-to-code pipeline
• Choosing between flexbox vs grid vs absolute positioning when the source is freeform geometry
• Translating Sketch-specific primitives (MSImmutableFlexGroupLayout, attributedString, curvePoint, MSImmutableStyleCorners) into idiomatic CSS
