Worked on the moltbot/moltbot repository to enhance the reliability of Feishu Bitable Write Tools, focusing on backend development and API integration using TypeScript. Addressed an AWS Bedrock validation issue by introducing a non-empty value schema, replacing free-form field maps with a validated FlexibleFieldValue schema to ensure compliance and data integrity. Added regression tests to verify the robustness of the new schema and prevent future regressions, particularly benefiting Bedrock-backed Anthropic users and Feishu integrations. Demonstrated a methodical approach to schema generation with TypeBox and thorough testing practices, resulting in uninterrupted tool usage and improved backend validation workflows.
