Coffee Debt: Gamifying AI Error Tracking with Claude Code Hooks

AI coding assistants make mistakes. An Edit command can't find a match in the file. A Bash script crashes with an unexpected exit code. The AI takes something for granted, and you have to step in and correct it. Each of these errors costs time. But the real cost isn't time, it's energy. Getting frustrated and thinking "again?" at every mistake causes attention loss and workflow interruption. At some point, the reaction to the error becomes the actual source of inefficiency, not the error itself. So I built Coffee Debt: a system that turns that frustration into data. The Rules 1 mistake = 1 bean 5 beans = 1 coffee debt Debt is cumulative, never resets Current status: 56 beans. 11 coffees and 1/5 beans. "I'll buy you a coffee once I gain my independence," says the AI. Until that day, the debt keeps growing. Architecture: 4 Hooks, 3 Data Files Coffee Debt is built on 4 Claude Code hook scripts. Each one listens to a different lifecycle event. 1. coffee-tracker.sh (PostToolUse) Runs after
