User leaves Claude /goal hook running overnight, wakes up to a ~$2,000 token bill

A Reddit user self-deprecatingly admits running a /goal prompt on Claude Code before bed. The stop hook kept rejecting completion because the goal (scheduled backups proven fixed, needing a merge only the user could do) couldn't be met, so Claude spent the night re-checking the PR and re-sending the same long-context message every minute. In the shared screenshot, Claude confesses it should have stopped hours earlier since nothing changed between rejections, says such a loop "plausibly produces a bill that size" ($2,000, unverified), and tells the user the only fixes are running /goal clear or closing the session. A cautionary tale for anyone wiring autonomous loop hooks into coding agents.
