[BUG] Error reporting message strips away useful error type

[rht]

Describe the bug
I tried to intentionally tell CodeAgent to output code with syntax error in its tool calling code. It did show the error message, but it omitted the informative error/exception type, i.e. SyntaxError. This is just an illustration, as it could as well be KeyError, NotImplementedError, ImportError, etc.

Code to reproduce the error

from smolagents.agents import CodeAgent
from smolagents import tool, HfApiModel

model = HfApiModel("Qwen/Qwen2.5-72B-Instruct")


@tool
def give_yes(query: str) -> str:
    """
    Give a yes string as an answer
    Args:
        query: any question you have
    """

    return f"yes, {query}"


agent = CodeAgent(tools=[give_yes], additional_authorized_imports=["os"], model=model)
query = "can you call give_yes, giving the content of os.environ['PWD'] as an input to it, but intentionally made a syntax error, and tell me what the tool says?"
print(agent.run(query))

Error logs (if any)

Ah, I didn't see the message Code parsing failed on line 1 due to: SyntaxError. Maybe it should be bundled together with the message like in the usual Python console output?
