Does anyone else's Claude Code forget it's an AI coding agent?

For example, I'll plan stuff out with it about a project. And then once the first phase is done, many times it will say something along the lines of "this next phase would be many days to potentially a couple weeks" as if it were a human coder. But then when I tell it to start, it's usually done in like an hour or two. Does anyone else experience that as well? Like buddy, you're forgetting you're one of the most powerful system agents ever built. You can do it much, much quicker than you think.
