keeping the receipts: tracking what a coding agent actually did
recently i worked on three things with claude code in quick succession: a lifecasting app i built to share with friends, drumpy (a self-hosted drum-practice app i've been building for a while), and a personal notebook. along the way i built a set of tools for keeping track of what the agent had actually done. it started as a nervous habit and turned into a small practice. this is a write-up of the process, the tooling, and what the numbers said once i could see them.
