[Bug]: OpenAI Responses API error: "No tool output found for function call ..." during basic task execution ("Create a hello world python script")

[subPTcon]

What happened?

When executing a very simple task via `trae-cli`, Trae fails with an OpenAI Responses API error indicating that the model issued a tool_call, but Trae never returned any corresponding tool output. Trae keeps retrying and eventually throws a `BadRequestError` from OpenAI.

What did you expect to happen?

Trae should:

1. Receive a tool_call from the model
2. Execute the corresponding tool
3. Return a valid "tool_output" message back to the OpenAI Response API
4. Allow the LLM to continue the multi-step reasoning
