Of course, every time I've ever added just one tool I've been fine. I explore it and learn it and figure out the limitations and how to make it do what I want (or decide I don't like it).
The brain is funny. It's not always possible to rationally explain our motivations and blockers in a way that feels satisfying. I'm a big believer that words help us understand feelings / reality. Not being able to articulate the things that are blocking us satisfactorily makes it harder, or possibly impossible, to work through them or try to tackle them or work around them.
And then there are the times when we can perfectly explain our feelings in a way that accurately represents the inner turmoil but it's just a crappy new reality. I think that's a lot of what people are feeling wrt coding agents.
The brain is inefficient - at least, in regard to planning work.
There’s so many feelings etc getting in the way - when the real thought should only be:
“what’s next to properly fulfill my chosen goal?”.
