Worked on enhancing API error handling in the sst/opencode repository, focusing on improving stability and developer experience. Developed targeted logic in TypeScript to explicitly classify 'context_length_exceeded' as a context overflow, refining how error responses are parsed and interpreted. Added robust detection for vLLM context overflow errors to prevent misclassification, which reduces false alerts and increases the reliability of API calls. Emphasized maintainability by improving the overall structure of error management. Leveraged skills in API development, error handling, and unit testing to deliver these improvements, resulting in more dependable API interactions and a streamlined process for managing error conditions.
