Ah yes, the agents by default are very "implementation" oriented, which is why I instruct mine to never implement something without formulating a plan first for me to approve.

Another thing they tend to do is rely on their own context -> memories -> training data. And if that's wrong then they'll continue with it until you instruct them to research, after which they usually get the right answer.

I've noticed that the newer models keep track of what you type so as to anticipate what you're likely to say. For example, today Opus 4.8 said "You usually don't want me to commit until you've checked, so the change remains uncommitted."
