Worked on the spotinst/openapi repository to deprecate the evaluationPeriods parameter from the cluster create and update OpenAPI schemas, aiming to streamline configuration practices and reduce user confusion. The approach involved updating the YAML-based schema definitions and enhancing API documentation to clearly communicate the deprecation, steering users toward current configuration options. By focusing on schema definition and API documentation, the work improved the clarity and maintainability of the API contract. These changes are expected to lower future support overhead and facilitate smoother customer onboarding, reflecting a thoughtful approach to long-term API usability and documentation accuracy without introducing new bugs or regressions.
