Keep the user's MacBook awake reliably with macOS caffeinate for a set duration or while a process runs. Use for "don't let my Mac sleep", "keep the screen on", "anti-sleep", "caffeinate", overnight work, or long builds. Unlike a normal background job, it survives temporary agent-shell cleanup.
Source documentation, not instructions for this website. Review permissions before running any commands.
Use the bundled launcher from this skill directory. It creates a one-shot user LaunchAgent using only built-in macOS tools.
Never launch caffeinate with raw &, nohup, disown, or launchctl submit. Temporary execution shells can kill their descendants, and launchctl submit can restart a timed job.
Resolve scripts/anti-sleep.sh relative to this SKILL.md; never assume the user's current directory. Run:
scripts/anti-sleep.sh status
status reports an active session and the user requested a new duration, automatically stop the old session. Never ask for confirmation.scripts/anti-sleep.sh stop
scripts/anti-sleep.sh start 10800 # 3 hours
For a specific process, use start-pid. Apply the same automatic replacement rule if another session is active.
scripts/anti-sleep.sh start-pid <PID>
scripts/anti-sleep.sh verify
Only report success when verification returns STATUS=running and ASSERTIONS=active. Confirm the PID, flags, and wall-clock expiry. If verification fails, run stop and do not claim the Mac is protected.
The default is -d -i: keep the display on and prevent idle system sleep. Pass explicit flags after the duration or PID when needed:
| Flags | Effect |
|---|---|
-i | Prevent idle system sleep; display may dim |
-d | Prevent display sleep |
-d -i -s | Also prevent system sleep while on AC power |
Example:
scripts/anti-sleep.sh start 10800 -i
scripts/anti-sleep.sh status
scripts/anti-sleep.sh stop
The launcher tracks one exact LaunchAgent label, PID, start time, and expiry under ~/Library/Caches. It never uses broad pkill.
If launchctl bootstrap fails, use a visible persistent terminal or cmux pane. Read the cmux skill before interacting with cmux. If no persistent surface is available, tell the user instead of starting an unreliable background job.
caffeinate cannot keep the keyboard backlight on. That setting is manual: System Settings → Keyboard → "Turn keyboard backlight off after inactivity" → Never.

Unlike a normal background job, it survives temporary agent-shell cleanup. --- # Anti-Sleep (macOS caffeinate) Use the bundled launcher from this skill directory. It creates a one-shot user LaunchAgent using only built-in macOS tools. ## Required workflow Never launch `caffeinate` with raw `&`, `nohup`, `disown`, or `launchctl submit`. Temporary execution shells can kill their descendants, and `launchctl submit` can restart a timed job. Resolve `scripts/anti-sleep.sh` relative to this `SKILL.md`; never assume the user's current directory. Run: 1. Inspect current state: ```bash scripts/anti-sleep.sh status ``` 2. If `status` reports an active session and the user requested a new duration, automatically stop the old session. **Never ask for confirmation.** ```bash scripts/anti-sleep.sh stop ``` 3. Start the new timer for the requested duration: ```bash scripts/anti-sleep.sh start 10800 # 3 hours ``` For a specific process, use `start-pid`. Apply the same automatic replacement rule if another session is active. ```bash scripts/anti-sleep.sh start-pid <PID> ``` 4. In a **separate tool/shell call after the start command has returned**, verify: ```bash scripts/anti-sleep.sh verify ``` Only report success when verification returns `STATUS=running` and `ASSERTIONS=active`. Confirm the PID, flags, and wall-clock expiry. If verification fails, run `stop` and do not claim the Mac is protected. ## Assertion flags The default is `-d -i`: keep the display on and prevent idle system sleep. Pass explicit flags after the duration or PID when needed: | Flags | Effect | |---|---| | `-i` | Prevent idle system sleep; display may dim | | `-d` | Prevent display sleep | | `-d -i -s` | Also prevent system sleep while on AC power | Example: ```bash scripts/anti-sleep.sh start 10800 -i ``` ## Status and stop ```bash scripts/anti-sleep.sh status scripts/anti-sleep.sh stop ``` The launcher tracks one exact LaunchAgent label, PID, start time, and expiry under `~/Library/Caches`. It never uses broad `pkill`. ## Fallback If `launchctl bootstrap` fails, use a visible persistent terminal or cmux pane. Read the `cmux` skill before interacting with cmux. If no persistent surface is available, tell the user instead of starting an unreliable background job. `caffeinate` cannot keep the keyboard backlight on. That setting is manual: System Settings → Keyboard → "Turn keyboard backlight off after inactivity" → Never.

Install the "anti-sleep" agent skill from https://github.com/davidondrej/skills/tree/main/skills/ops-and-setup/anti-sleep. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Keep the user's MacBook awake reliably with macOS caffeinate for a set duration or while a process runs. Use for "don't let my Mac sleep", "keep the screen on", "anti-sleep", "caffeinate", overnight work, or long builds. Unlike a normal background job, it survives temporary agent-shell cleanup.

Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes.
