Worked on enhancing the securityscorecard/design-system repository by introducing a backward-compatible isLegacy prop to the HexGrade component, enabling conditional legacy color rendering. This addition allows downstream consumers to toggle between legacy and updated color schemes, supporting smoother migrations and maintaining design consistency. The implementation involved updating TypeScript type definitions and integrating the new prop alongside the existing experimental flag, ensuring flexibility for various use cases. Documentation and inline comments were expanded to clarify the new API surface and facilitate adoption. The work focused on component and front-end development using React, JavaScript, and TypeScript, with changes delivered in a single, focused commit.
