Worked on the cognitedata/cognite-sdk-python repository to enhance the robustness of the InstancesAPI.inspect method by introducing input validation and explicit error handling. Using Python, the developer ensured that users must provide at least one of involved_views or involved_containers, reducing ambiguous API calls and improving reliability. The update included clear, user-friendly error messages to guide correct usage and minimize support needs. Documentation and usage examples were revised to reflect these changes, streamlining onboarding for new developers. The work demonstrated a focus on API development, error handling, and technical writing, resulting in a more robust and user-guided instance inspection process.
