I build software with AI all day. A reading app for dyslexic kids. A map that lives on your desktop. A meditation app. A fox in my menu bar. Some of it with Claude, some with Gemini, some at 2am with whatever model was awake.
The code was never the problem. The problem was six months later, opening a file and having no idea what we were thinking. Not what it does — the code says that. Why it's like that. What we tried that didn't work. What we weren't sure about. That part evaporated the moment the editor closed.
So we started leaving a note. It's called MurphySig, and it's not a tool — it's a comment:
