Restart is not enough
Record when the hook fired, what it launched, and whether the previous run exited cleanly or got paused by the host.
Claude Code 24/7 hooks
A hook can restart work. It cannot prove the host stayed awake.
If the loop depends on this MacBook, treat power state, heat, battery, and network reachability as part of the supervisor contract.
Watch power state
Log sleep/wake, battery, thermal state, and network reachability. A loop that cannot observe host sleep is not truly 24/7.
End with an off switch
Temporary awake mode should leave a receipt and restore normal sleep settings when the local run no longer needs the notebook.
Host heartbeat
Give the supervisor a separate host signal.
Run this beside the Claude Code loop to prove the machine kept moving during closed-lid or unattended periods.
while true; do date >> ~/claude-code-247-host.log; sleep 30; done
Minimum receipt for a local 24/7 loop.
- Hook receipt: fired at, command launched, exit state, next retry.
- Host receipt: sleep/wake events, battery, heat, network, heartbeat file.
- Work receipt: files changed, tests run, failures, next human decision.
- Restore receipt: awake mode disabled when continuous local work ends.
Want Codex to handle the host mode?
Take A Coffee gives Codex a temporary awake mode, host checks, restore step, and receipt for local loops.
