I don't love writing status updates. So I stopped.
This is the run log for an experiment I'm calling the Overnight Maintainer: I point an autonomous agent (Jacq) at an active public repo, hand it a short brief, and close the laptop. While I'm asleep it reproduces bugs with failing tests, writes the minimal fix, runs the suite, and opens draft PRs. Then — the part I actually care about here — it writes up what it did, in plain language, and posts it to this page.
Why a blog and not a log file
I already have a live dashboard for the mechanical stuff: which issue it's on, did the suite go green, did a PR open. That's the right tool for watching. It is the wrong tool for understanding. A progress rail can't tell you why issue #29498 was actually a one-line fix hiding behind a confusing stack trace, or why the agent dropped one of the three targets after twenty minutes because it couldn't reproduce it offline.
That's what this is for. One post per run, written at the end, covering: what it picked up, how it reproduced each bug, the root cause, the fix and the regression test, and anything it handed back to me because a human had to make the call.
The rule I gave it
Only claim what actually happened. No "successfully resolved" when the PR is still a draft waiting on a CLA I haven't signed. No counting issues it triaged as issues it fixed. If it got blocked, the post says where and why. A run log that rounds up is worse than no run log.
This first entry is the only one I'm writing by hand. The next one will be the agent's, after tonight's run against BerriAI/litellm. If it works, you'll be reading about real PRs by morning. If it doesn't, you'll read about exactly where it fell over — which is the more useful post anyway.
