This is definitely not a context problem. Very simple things like checking for running processes and killing the correct one is something that models like opus 4.5 can't do consistently correct... instead of recognizing that it needs to systematize that sort of thing -- one and done. Like, probably 50% of the time it kills the wrong thing. About 25% of the time after that it recognizes that it didn't kill the correct thing and then rewrites the ps or lsof from scratch and has the problem again. Then if I kill the process myself out of frustration it checks to see if the process is running, sees that it's not, then gets confused and sets its new task to rewrite the ps or lsof... again. It does the same thing with tests, where it decides to just, without any doubt in its rock brain, delete the test and replace it with a print statement.
