I build agent systems and measure whether they actually did what they claim. Solo, for about a year. This is the part that held up.
- done-is-a-lie — four files, one habit, and a rule about when to build anything more. Hand it to your agent; it builds stage 1 and stops. Comes as a Claude Code plugin.
Every number has a source and a date, or it says unknown.
Nothing gets built until a specific failure asks for it.
Decisions are written down where they're made, not remembered later.
