A Figma-to-code result should be accepted against the intended component behavior, not only a screenshot of its default state. MCP can provide design context, but the application still needs correct interactions, responsive behavior and accessible semantics. Define acceptance before asking an agent to implement a frame.

The contract to define first

Build a state inventory covering default, loading, empty, error, disabled and permission-restricted views. Map those states to existing components and tokens. Compare rendered output at representative widths, then perform the actual task with keyboard and assistive technology where applicable. Current Figma tools and access conditions should be checked in the official documentation rather than assumed from an old tutorial.

A worked scenario

A synthetic client card matches the design visually but makes the entire card clickable around a nested menu. The screenshot alone may look correct while keyboard focus and event handling fail. Acceptance needs to cover the menu, primary navigation and denied-access state as well as spacing.

An implementation and review sequence

  1. List component variants and interaction states
  2. Map the design to existing tokens and components
  3. Verify rendering and task completion across viewports

Failure cases worth testing

Compare rendered output to component state and interaction requirements. Use this matrix as a starting fixture and adapt the expected behavior to the documented product contract.
Condition or inputExpected behavior
Default view matches but error state is absentThe implementation is incomplete
Keyboard opens the action menuFocus and dismissal remain predictable
Mobile width changesContent hierarchy and actions stay usable

Tradeoffs and limits

Pixel comparison can highlight visual drift without proving usability. Combine targeted visual checks with a small set of meaningful interaction tasks instead of treating one similarity score as completion.

Use the result to make a decision

The practical output is straightforward: compare rendered output to component state and interaction requirements. Keep the assumptions with the artifact so a product owner, implementer or prospective partner can review the same decision. A useful handoff states the supported scope, the evidence collected and the remaining dependency instead of treating a successful demonstration as proof of every operating condition.

How should Figma-generated code be accepted?

A Figma-to-code result should be accepted against the intended component behavior, not only a screenshot of its default state. Pixel comparison can highlight visual drift without proving usability.

Which failure cases should be included in the review?

Include these explicit cases: Default view matches but error state is absent: the implementation is incomplete; Keyboard opens the action menu: focus and dismissal remain predictable; Mobile width changes: content hierarchy and actions stay usable.
