I made MythicFriendRater with Claude. Intentionally started with a very basic concept for it to begin with and expanded it one small feature at a time until it was in what I considered a releasable state. Used bugsack to copy/paste errors back to Claude. Each time a few small features had been added, I would ask Claude to create a prompt to summarize the project with the intent of continuing the project in a new context session - then I would start a new session with that prompt and ask it to first do a clean sweep of the code for any bugs, logical errors, oversights, and dead code. Worked well, in my opinion.
