CodeAct's Execution Behavior: Can It Optimize Code Before Running?

[relic-yuexi]

Hi everyone,

I’ve been experimenting with CodeAct and noticed a potential issue: it seems to execute code immediately after it’s provided, without offering an opportunity to optimize or refine it first.

For example, take the following snippet where I define a tool to read file content and pass it to a CodeAgent:

from smolagents import OpenAIServerModel, CodeAgent, ToolCallingAgent, UserInputTool, PythonInterpreterTool, FinalAnswerTool, VisitWebpageTool, tool

@tool
def read_file_content(file_path: str) -> str:
    """
    Reads the content of a file and returns it as a string.
    """
    with open(file_path, 'r') as file:
        return file.read()

manager_agent = CodeAgent(
    tools=[UserInputTool(), PythonInterpreterTool(), FinalAnswerTool(), VisitWebpageTool(), read_file_content],
    model=model,
    additional_authorized_imports=['os', 'io'],
    verbosity_level=2,
)

manager_agent.run("improve the xxx.py code")

If the code in xxx.py has inefficiencies or bugs, the system will execute it as-is without giving me a chance to review or optimize it. This could lead to suboptimal results or unintended behavior.

Questions:

1. Is there a way to introduce a pre-execution step for code optimization?
2. Could the system provide suggestions or allow manual refinement before running the code?

Would love to hear your thoughts or any workarounds you might suggest!

Best regards!
