Python extension prompts blocking Copilot agent flow

[waldekmastykarz]

When using the Copilot in latest VSCode stable on Windows, I noticed that the Python extension shows prompts like:

There's also another variant of the prompt asking for the path to the Python executable.

Both prompts have been triggered from Copilot while building a Python app in agent mode using Opus 4.5. I've only seen these prompts on Windows and not on macOS. Prompts like these break the Copilot's agent flow because they require user interaction and prevent the agent from figuring out the requirements by itself.

Thanks for creating Waldek Mastykarz (@waldekmastykarz), Eleanor Boyd (@eleanorjboyd) can you look into this? I tested on my machine and agent did the decision making autonomously so there may be a bug here

Yes- I will give this a try and follow up based on if it works for me. Thanks for the issue report!

🤖 Closing this issue here because the agent-blocking environment prompt is being tracked in microsoft/vscode-python#25940, where the configure_python_environment tool and its interactive picker are owned. That issue is assigned to Stella Huang (@StellaHuang95) and marked important. The executable-path prompt mentioned here should also be checked as part of that investigation so it is not lost in the handoff. We can reopen here if a distinct Python Environments bug is identified.
