Level up design-to-code collaboration with GitHub’s open source Annotation Toolkit

GitHub open sourced the Annotation Toolkit, a Figma library that improves design-to-code handoffs by embedding accessibility documentation directly into design files. The toolkit uses numbered annotation stamps to document design intent, WCAG compliance requirements, and interactive behaviors, preventing accessibility issues before they reach production. GitHub's internal data showed 48% of accessibility audit issues could have been prevented with better upfront documentation. The toolkit is available on Figma Community and GitHub, includes interactive checklists and WCAG guidance, and accepts community contributions.
