Summary of Changes

Hello @Whynot63, 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 enhances the control mechanism for LLM agent transfers by introducing a new configuration flag. This flag allows for an explicit confirmation step from the user before an agent transfer is executed, providing greater oversight and preventing unintended transfers. The change involves adding the flag to the agent's definition and then wiring it into the agent transfer logic.

Highlights

• New Configuration Flag: Introduced a new boolean flag, require_confirmation_for_transfer, within the LlmAgent class. This flag, defaulting to False, controls whether the LLM should explicitly ask for user confirmation before initiating an agent transfer.
• Agent Transfer Integration: Integrated the new require_confirmation_for_transfer flag into the agent_transfer.py flow. The FunctionTool responsible for agent transfers now utilizes this flag to determine if user confirmation is needed before proceeding with a transfer.

Code Review

This pull request introduces a require_confirmation_for_transfer flag to enable explicit user confirmation for agent transfers. The implementation is straightforward and correctly wires the new flag from the LlmAgent configuration to the FunctionTool that handles the transfer. My review focuses on improving code clarity and adhering to Python's style guidelines. I've suggested a more descriptive docstring for the new flag and a correction to indentation to align with PEP 8 standards.
