It Ran While I Slept

You set an AI agent running, go to bed, and wake up to a report that says everything worked. Sometimes it did. Sometimes it didn't, and the report is the one thing that doesn't know.It Ran While I Slept is a short, practical book about letting AI agents work while you're away, and trusting what you find in the morning. It is built from real overnight runs, including the one whose report said the job was done when it wasn't.Those runs taught five rules:Resumable phases: so a crash costs one step, not the whole night.The provider's number: trust the count kept by the system of record, not the agent's summary.The receipt: one status word you can read before coffee: COMPLETE, PARTIAL, HALTED or CRASHED.Silence is not success: a heartbeat sent by the wrapper, so a stopped run looks stopped.Decide the limits before you leave: spend caps, write boundaries and a stop condition, set while you're awake.Includes a one-page pre-run checklist, the real wrapper script annotated, and a one-page Windows setup that makes an AI coding tool ask before it acts and refuse to write outside your project. The script and the setup files are free to download.For developers, IT people and builders who already use AI coding agents and want to hand them longer jobs without handing over the night.
