Worked on the CherryHQ/cherry-studio repository to enhance the Hub MCP tool call system, focusing on robust handling of multi-element responses and structured content. Developed features in TypeScript that preserved all text blocks in tool responses, preventing data loss and ensuring accurate payload delivery to downstream tools. Introduced array-based outputs for multi-block responses, allowing execution-time code to iterate over complete results and improving compatibility with downstream tooling. Maintained backward compatibility for single-block responses while updating parsing logic and structured content typing. Prioritized reliability and developer experience by upgrading hub bridge paths to reduce workflow failures and align with evolving MCP specifications.
