Design Handoff Completeness
Developers have everything they need to implement without guessing.
Check
Every design file includes: all interactive states (default, hover, focus, active, disabled, error, loading), exact spacing values (not "about 16px"), component names matching code, and annotation for non-obvious behaviors (animations, conditional visibility, validation logic).
Why This Matters
Incomplete handoffs are the #1 source of implementation inconsistency. When developers must guess states or measurements, the result is a product that looks different from the design — and rework is expensive after implementation.

How to Verify
Have a developer review the file without asking the designer any questions. Any question they have = a gap in the handoff. Fix every gap before implementation begins.
