The Ralph Method
Let AI Build Your Software From Start to Finish
The best approach I've found for having AI build complete software projects autonomously. You describe what you want, define what "done" looks like, and Ralph loops until you get there. The magic is in eventual convergence: each iteration brings the project closer to your goals, even if individual steps aren't perfect. I've used it to build multiple systems myself, and a friend used it to build a complete Smalltalk VM over a single weekend.
