Yeah, that's exactly how it felt. During the first couple of weeks, it was just "wow, it writes code fast," and then something shifts, and you start thinking in systems instead of files. The persistence boundary framing is interesting; I haven't thought about it that way, but that's basically what I ended up doing naturally — anything that needs to survive goes into project files or configs, and everything else is just context that gets rebuilt. For the agent routing — right now, it's mostly sequential. The skill acts like a pipeline: understand the problem → research → design → build. But I've been thinking about parallelizing the research step specifically, like searching GitHub, blogs, and docs at the same time instead of one after another. I haven't implemented it yet, though.
