All the models I have used will frequently jump ahead a ton of steps and not verify any of its assumptions. From generating a ton of code output I didn't ask for, to making a ton of assumptions about what I'm working on without appropriate context.

Yeah, /plan is the only way I can work with them now. Too much "helpful" crap I didn't ask for. Having nightmares of former coworkers who would want to refactor 80% of the code base for a 3 line change. AI doesn't subscribe to "if it ain't broke, don't fix it."
