Ive been noticing something similar recently. If somethings not working out itll be like "Ok this isnt working out, lets just switch to doing this other thing instead you explicitly said not to do".
For example I wanted to get VNC working with PopOS Cosmic and itll be like ah its ok well just install sway and thatll work!
Experienced this -- was repeatedly directing CC to use Claude in Chrome extension to interact with a webpage and it was repeatedly invoking Playwright MCP instead.
I actually submitted an upstream patch for Cosmic-Comp thanks to Claude on Saturday. I wanted to play Guild Wars remake and something was going on with the mouse and moving the camera. We had it fixed in no time and now shit is working great.
