Tip: A Cron Job Can Keep Your Local Patches Rebased Against Upstream Automatically
Simon Willison·medium signal
Simon Willison highlighted a prompt from David Crawshaw on August 3 that turns the chore of maintaining a local fork into a scheduled agent task: the agent rebases your local modifications against upstream on a cron cadence and reports what it had to resolve. This is a low-blast-radius entry point into scheduled agent loops because the failure mode is a conflict report, not a broken main branch. It pairs naturally with worktree isolation so the rebase attempt never touches your working copy.
