Worked on the lichess-org/api repository to restore and document the color property for the Seek API, enabling clients to specify move colors as random, white, or black, with random as the default. Focused on aligning API documentation with the underlying codebase, the work clarified integration points and reduced ambiguity for client developers. Utilized YAML for precise API documentation and applied careful API design principles to ensure maintainability and clear semantics. No bugs were addressed during this period, with efforts concentrated on feature delivery and documentation accuracy, resulting in improved onboarding and more predictable behavior for API consumers integrating with the platform.
