Code Review
This pull request refactors RequestContext to encapsulate the full SendMessageRequest payload instead of individual properties, introducing a RequestContextParams interface and updating the request handler and tests accordingly. The review feedback highlights that assigning params.request directly via a shallow reference allows downstream executors to mutate the original request object, and suggests using structuredClone to deep-copy the request and maintain state safety.
Important
The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
