description

Keep this Mac awake — prevent display sleep, system sleep, and disk sleep so long jobs (renders, browser automation, downloads, training) run uninterrupted. Trigger when the user types "caffe", "caffe mode", "caffeinate", "keep awake", "no sleep", "อย่าให้เครื่องหลับ", "อย่าให้จอดับ", "กันเครื่องหลับ", "เปิดโหมดไม่หลับ", or "รันไปเรื่อยๆ". Also handles turning it off ("caffe off", "caffe stop", "ปิด caffe") and checking status ("caffe status").

craft-caffe — keep the Mac awake (macOS caffeinate)

A tiny utility skill. It manages a detached caffeinate -dimsu process so the machine never sleeps while long-running work is in progress.

-d no display sleep · -i no idle sleep · -m no disk sleep · -s no system sleep · -u user-active. The process is started with nohup ... & so it survives closing this terminal / Claude Code session (but NOT a reboot — for a permanent setting use sudo pmset, offer it only if asked).

macOS only — check before doing anything

caffeinate exists only on macOS. If this isn't macOS, stop and say so — don't run a command that isn't there. Point the user at the equivalent (Linux: systemd-inhibit or the caffeine app; Windows: powercfg / PowerToys Awake).

[ "$(uname)" = "Darwin" ] && command -v caffeinate >/dev/null \
  || { echo "caffe is macOS-only (got $(uname)) — not running"; exit 0; }

Decide the intent from the user's words

• "caffe", "caffe mode", "keep awake", "เปิดโหมดไม่หลับ" → ON
• "caffe off", "caffe stop", "ปิด caffe", "ให้เครื่องหลับได้" → OFF
• "caffe status", "เช็ค caffe" → STATUS

Default to ON if ambiguous.

ON — enable keep-awake

1. Check if already active so you don't stack duplicates:

   pgrep -f "caffeinate -dimsu" >/dev/null && echo "already on" || echo "not running"
   

2. If not running, start it detached (do NOT use the Bash tool's run_in_background — that ties it to the Claude session; nohup survives the terminal closing):

   nohup caffeinate -dimsu >/dev/null 2>&1 &
   

3. Verify and report the active assertions:

   sleep 1; pmset -g assertions | grep -E "PreventUserIdleDisplaySleep|PreventUserIdleSystemSleep|PreventSystemSleep"
   

4. Tell the user it's ON, that it survives closing the terminal but not a reboot, and how to turn it off (caffe off). Mention the clamshell caveat only if relevant: closing the laptop lid with no external display/power will still sleep.

OFF — let the Mac sleep normally again

pkill -f "caffeinate -dimsu" && echo "caffe off" || echo "was not running"

Confirm it's off. Leave any system caffeinate -i -t <n> processes (those are short-lived OS ones) alone — only target the -dimsu instance this skill starts.

STATUS — report current state

pgrep -lf "caffeinate -dimsu" || echo "caffe is OFF"
pmset -g assertions | grep -E "PreventUserIdleDisplaySleep|PreventUserIdleSystemSleep"

Notes

• macOS only. setsid is unavailable on macOS — use nohup ... &.
• Permanent (survives reboot) = sudo pmset -a displaysleep 0 sleep 0 disksleep 0. Only do this if the user explicitly asks; record the old values first (pmset -g) so it can be reverted.
