Humbug is a GUI designed to let you do more structured software engineering with AI. Most of the development work has been driven using Metaphor, a very simple natural-language based format for capturing detailed context.

Metaphor aims to make development prompting much more repeatable and to offset many of the concerns that experienced engineers have with using AI. It provides a framework to capture the important learnings from interactive discussions and continually refine them in a way that gets much more predictable and higher quality software as an output.
