Type: Bug

  1. Use github copilot chat with agent mode and Claude Sonnet 4 and ask copilot to do a task that needs querying in terminal, generating file and executing commands in terminal.
  2. It will switch directory and write files in a terminal, and check files in this terminal, but execute the file in a new terminal! Then find out that the file doesn't exist in the new terminal. It will repeat querying and generating file in one terminal, and executing in a new terminal and keep failing.
  3. Tell copilot it should not execute command in a new terminal. It will agree, but continue repeating this circle.

This makes task broken again and again and again and again.
