Plans

A Research-Plan-Implement (RPI) workflow for AI-assisted software development with human-in-the-loop checkpoints. This document serves as a reference for both AIs and humans, ensuring quality through structured research, planning, and implementation phases, with AI self-review applied to implementation.

Learn about the theory behind RPI from Dax: https://www.youtube.com/watch?v=rmvDxxNubIg

All work for a feature or change happens in a dedicated plan folder (e.g., plans/a7z-feature-name/). Each plan folder has a corresponding git branch and pull request, keeping code changes tied to their documentation.
