The new prompt is still not explicit about “plan only / do not implement yet,” which is the stated goal in the PR description for preventing Plan mode from attempting actions.

Summary
Seems like there were frequent situations where the "Plan" mode prompt was stuck on some of the tool calls - quite often
Get last terminal command. I don't know the root cause for sure but I suspect that Copilot may sometimes not realize it is in plan mode and is trying to perform actions which are not allowed there.Here is a sped up video of me going through the exercise as normal and after ~3min I cancelled the prompt because I ran into the reported issue. I switched the prompt a bit to imply we want to be planning and it ran without an issue

Changes
Updated the plan mode prompt to be more explicit that we want to Plan the tests and not implement them immediately.
