Design Handoff Checklist for Faster Engineering

Ambiguous handoff creates silent delays. Engineers should not invent empty states or error copy.

Provide responsive layouts, component states, and content rules for long text and missing data.

Include interaction notes for motion, loading, and disabled actions. Assumptions here cause polish debt.

Name components consistently with the design system so implementation maps cleanly.

Tight handoffs are how two-week website builds stay on schedule without weekend fire drills.
