Close the lid. Let the agent finish.

SleepWalk keeps your Mac awake for long Cursor, Claude Code, Codex, Windsurf, and terminal-agent runs, then lets the session end when the agent signals done.

Works with every agent

SleepWalk keeps the Mac awake underneath your editor, CLI, or coding assistant.

Agent Auto-Stop

Done means stopped

The SleepWalk skill gives AI coding agents a local done signal. When checks pass, the agent stops the timer itself.

Frequently Asked Questions

Who is SleepWalk for?

SleepWalk is for software engineers who leave AI coding agents running in Cursor, Claude Code, Codex, Windsurf, terminals, and local dev tools, then need to step away or close the lid.

Can I close my MacBook lid while an agent is running?

Yes. SleepWalk is designed for closed-lid agent runs when macOS and your hardware setup allow them. Start a bounded session, close the lid, and let the agent continue while SleepWalk watches your limits.

How is SleepWalk different from Caffeine, Amphetamine, caffeinate, or pmset?

Those tools can keep a Mac awake, but they are easy to leave running. SleepWalk is built for AI-agent work: quick menu setup, explicit battery and temperature guardrails, closed-lid sessions, and agent auto-stop through the SleepWalk skill.

Can the agent start and stop SleepWalk itself?

Yes. Install the SleepWalk skill once, and an AI coding agent can start a session, mark itself active or idle, and stop the timer when the task is done.

Which agents does SleepWalk support?

SleepWalk is agent-agnostic. Any coding assistant, editor, CLI, script, or workflow that can call the local SleepWalk CLI can use the same bounded session controls.

Does SleepWalk watch my editor, prompts, or terminal output?

No. SleepWalk does not inspect prompts, windows, logs, code, or network traffic. Agent auto-stop uses explicit local signals from the SleepWalk skill and CLI.

What happens when a limit is reached?

SleepWalk ends the session when the timer expires, the battery drops below your floor, the Mac gets too hot, or the agent marks the task done.
