Developer Handoff & Inspect
Developers open the file (or Dev Mode) to inspect spacing, fonts, colors, and CSS/iOS/Android snippets. Clean Auto Layout and styles make inspect output useful; messy absolute positioning does not.

02What to include in handoff
- All interaction states: default, hover, focus, error, empty, loading
- Responsive frames: mobile, tablet, desktop when layout changes
- Export assets: icons SVG, photos @1x/@2x as needed
- Redlines or notes for animation timing and accessibility (contrast, focus order)
- Link to the prototype for flow context
03Talk like an engineer
Name components to match code (Button / Primary, Input / Error). Document tokens that map to CSS variables or Tailwind theme keys.
Real-life example: Handoff is the recipe card for the kitchen. Missing states force developers to invent behavior — and inventing creates bugs.
