This PR updates the system prompt's TASK MANAGEMENT PROTOCOL to explicitly instruct the agent to batch tracker_update_task calls with other tool calls in the same turn. This prevents the tracker from getting out of sync during multi-step processes and improves overall agent speed and efficiency. Fixes #23129

Summary of Changes

Hello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request improves the agent's task tracking efficiency and reliability by enforcing parallel updates. By instructing the agent to bundle tracker updates with other tool executions, the system reduces the number of turns required for task management and ensures the tracker state remains synchronized with the actual work performed.

Highlights

  • System Prompt Update: Updated the TASK MANAGEMENT PROTOCOL to explicitly require batching of tracker_update_task calls with other tool calls in the same turn.
  • Test Coverage: Added a new evaluation test case to verify that the agent correctly performs parallel tracker updates during task completion.

Code Review

This pull request introduces a new 'PARALLEL UPDATES' guideline to the task tracking system, instructing the model to combine tracker updates with other tool calls in a single turn for better efficiency. Corresponding updates were made to the prompt snippets and snapshots, along with a new evaluation test to verify this behavior. Feedback was provided regarding the risk of race conditions when performing parallel updates to the tracker, suggesting the use of synchronous I/O or avoiding parallel execution in test contexts to ensure data integrity.
