Worked on the zed-industries/zed repository to address a reliability issue in DashScope tool calls during streaming delta events. Focused on backend development using Rust, the developer implemented non-empty value guards to ensure that tool identity fields such as id and name were only updated when new, valid data was provided. This approach prevented the inadvertent loss of tool identity across multiple streaming chunks, aligning the implementation with established patterns from the Hermes Agent and OpenAI SDKs. The work included writing automated tests to validate streaming delta behavior and updating release notes, resulting in more robust and predictable backend tool interactions.
