Qwen 3.6 27B overdoing it

Although I'm very impressed with Qwen3.6 and is my most used model, I feel that sometimes it being too proactive and start doing things I didn't ask, from creating tests for the last modification to reverting changes I made - eg removing an hardcoded value - that it thinks are instead useful to keep, and still others.

Are you also getting the same behaviour? If so, how do you counter it? Change the prompt? Use different temperature or other parameters?
