Summary of Changes

Hello @HenryHengZJ, 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 integrates the Gemini Code Interpreter feature, significantly expanding the capabilities of agents by allowing them to dynamically generate and execute Python code within a secure sandbox. This enhancement improves the agent's ability to perform complex tasks requiring computation and data manipulation, and provides a richer, more interactive experience by clearly presenting code execution steps and their outcomes in the chat interface.

Highlights

• Gemini Code Interpreter Integration: Introduced a new codeExecution tool, allowing agents to write and execute Python code in a sandboxed environment, significantly expanding their capabilities.
• Enhanced Response Handling: Implemented sophisticated parsing for Gemini model responses, enabling the display of executable code blocks, code execution results (output and errors), and text content in a structured format.
• Improved Tool Deduplication: Enhanced the logic for tracking used tools (googleSearch, urlContext, codeExecution) to prevent redundant entries by comparing their input parameters, leading to more efficient tool usage.
• UI Support for Code Execution: Added a dedicated icon for the codeExecution tool in the agent flow user interface, providing visual representation for the new functionality.

Code Review

This pull request adds support for the Gemini Code Interpreter, a valuable enhancement for the Agent node. The changes correctly introduce the new tool in the UI and backend, and handle the processing of code execution and results in both streaming and non-streaming modes. My review focuses on improving code quality. I've identified areas with significant code duplication that could be refactored into helper functions. I also noted a piece of logic for associating code with its output that could be made more robust. Finally, I've suggested improving type safety by replacing any types with specific interfaces for the new API response structures. These changes will make the code more maintainable and resilient.
