About this tool
Build a design-to-development handoff checklist for your platform and features, then score how ready the handoff really is.
A design handoff checklist is the list of artefacts a development team needs before it can build a screen without asking the designer another question. This generator filters a library of handoff checks down to the ones that apply to your platform and feature set, then scores completion with blockers weighted three times a nice-to-have, so an unticked blocker can never read as ready. Built for product designers, design system owners and engineering leads agreeing on a definition of done.

Provide your input — an image, text, or data.
Let the tool analyze or generate the result.
Review, refine, and reuse the output wherever you need it.
Motion, localisation and accessibility checks appear only when you say the project has them.
Missing focus states or unresolved tokens outrank a missing changelog in the score.
Copies as a GitHub-flavoured task list you can paste straight into an issue or pull request.
At minimum: a single source-of-truth file, named type and colour styles, every interactive state (default, hover, focus, active, disabled, loading), the narrowest supported layout, final copy, export settings for icons and images, and a written list of open questions. Anything a developer would otherwise have to guess belongs in the handoff.
Items that force a rewrite if they arrive late: missing interactive states, undefined tokens or colours, no layout at the smallest breakpoint, placeholder copy, missing font licences, and for animation, no reduced-motion fallback. This tool tags those as blockers and caps the readiness label until they are cleared.
WCAG 2.2 level AA asks for 4.5:1 for normal text, 3:1 for large text (at least 18.66px bold or 24px regular), and 3:1 for user interface components and meaningful graphics. Check these in both light and dark themes, since a dark palette rarely inherits the light one's ratios.
No. It removes the avoidable questions so the meeting can cover intent, edge cases and trade-offs. Teams that skip the conversation entirely tend to ship correct pixels with the wrong behaviour.
