I've been working on a pi extension to do this, after frustration with getting the best current local models to stay on track, and just to deal with their relative slowness; gist is that it uses pi hooks to keep the model deterministically on track and beads-rust issue tracking tool to keep everything organized.

A SOTA model writes the initial prompt, and creates the beads issues; then a continuous iteration of plan(local) -> review (sota) -> implement(local) -> review (sota). Until the sota reviewer model is happy with the implementation.

And can mostly just let-it-run; e.g. overnight since local models with mac unified memory are slow.

Still early days, but have had reasonably good success with a Defender (1981) clone and now I'm having it work on a Prince of Persia clone (both Go/ebiten).

Note: I think this is only possible now because Qwen3.8-Flash-Next and 27b are incredibly good models.
