Figma measured Code Connect across 27 design-to-code cases and found that production-accurate component snippets raised median code quality from 2 to 3 on a four-point scale, reduced token use by 29.5%, and shortened task duration by 19.6%. Coverage mattered most: agents with stronger mappings stopped inventing raw tabs and buttons and reached directly for the real design-system components.
Figma's nested-folders team demonstrates the organizational complement to that structured context. Engineers treated code as a proposal, the designer pushed selected changes, and the product manager concentrated on strategic risk and customer feedback. Rough prototypes were allowed onto staging so cross-functional conversations could happen against working software, while permissions, migration behavior, bug bashes, and early-access feedback remained explicit quality gates.
A practical design-token rollout follows the same gradual enforcement model: audit first, fix transformation-breaking references and type errors, block only cleaned-up critical rules, then manage warnings and time-limited exceptions as owned backlog. Whether the contract is a component mapping, an RFC, or a linter rule, it becomes useful only when ownership, rollout state, and actionable failure messages are encoded alongside it.
Axe MCP Server expands that feedback loop into authenticated and dynamic interfaces. Automated keyboard guided tests, advanced focus and contrast rules, cookie injection, component-scoped scans, and batches of up to 25 remediations bring more accessibility evidence into the IDE; organization-level WCAG and confidence policies keep the results consistent.
