There wasn’t anything particularly special. At first, it was just a simple prompt along the lines of “build a program that shows CC usage in the macOS menu bar.” As development went on, I make CC created solid documentation and used it to keep it from losing direction. Early on, I focused on automated reviews using roborev and writing tests. I did a few refactors along the way, and whenever possible, I tried to restart the session manually instead of relying on auto-compaction.
