Nightly routine reviewing the day’s pushes

Run every day at 1:07 AM on Opus 5.5 with no connectors attached. Save the instructions below as the prompt, word for word.

First install dependencies and run the full test suite. Note which tests were already failing. If the tests can't run, or there are none, write down what's missing and stop.

Then look at the commits pushed to the default branch in the last 24 hours. If there are none, end the run. Skip any bug that a claude/ branch is already fixing.

Only look for real bugs. Ignore style and naming. To call something a bug, you must be able to point to what a comment, the docs, a type, or an existing test says. If a change in behavior looks intentional, just note it. Don't fix it.

For each bug, write a failing test first. Make sure the failure message points to that bug, and rule out a broken test or an environment problem. Then change the code until the test passes, touching only what you must, and run the full suite again. Open one draft PR per bug with your evidence, three at most.

Never delete, change, or skip existing tests. Push only to claude/ branches. Don't merge anything.

Finish with a handoff note: the commits you checked, the PRs you opened, and anything that looked like a bug but couldn't be proven.
