Summary of Changes

Hello @feelshana, 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 addresses a fix in the ReActAgent to ensure that when an agent's execution is halted due to a Human-In-The-Loop (HITL) stop request, the Msg object correctly carries the specific reason for termination. This enhancement improves the clarity and traceability of agent execution, making it easier to diagnose and understand agent behavior.

Highlights

• Corrected Stop Reason Reporting: The ReActAgent now explicitly sets the GenerateReason to REASONING_STOP_REQUESTED or ACTING_STOP_REQUESTED when a Human-In-The-Loop (HITL) stop is triggered during the reasoning or acting phases.
• Enhanced Debugging and Traceability: This change provides more precise information about why an agent stopped, which is valuable for debugging, logging, and understanding agent behavior in interactive or supervised scenarios.

Code Review

This pull request correctly addresses the issue of missing reasons for agent stops. The changes in ReActAgent.java now properly set the GenerateReason to REASONING_STOP_REQUESTED and ACTING_STOP_REQUESTED when a stop is requested during the respective phases. This provides better observability into the agent's execution flow. The implementation is clean, uses the existing withGenerateReason method correctly, and aligns with the framework's design. The changes are accurate and improve the overall quality of the code.
