I did switch it to use ZODB for database instead of postgres, and fossil-scm instead of git, which it was able to successfully navigate. I'm a python head so this makes sense for me, ymmv - I have 30 years of development experience and that's what I choose to implement.
The hot/warm/cold didn't seem to materialize though, but the task focus kind of makes that a moot point.
I tried with claude, qwen, and gemini, all seemed to pick up and continue working. Work seems kind of slow, but it was all reviewable, clear goals and tasks, and overall kind of usable? I'll experiment a bit, but it seems promising. I still don't know why you wouldn't just have it build you a system then release that.
If it's a simple, extremely long prompt that should be copied and pasted without customisation, wouldn't it make more sense to build it as a set of skills?
