Usage

Ask Claude naturally:

• "不睡觉 30 分钟"
• "别睡，1 小时"
• "合盖不睡 2 小时"
• "恢复睡眠"
• "永远不睡"

Claude will call the lidajar_start / lidajar_stop / lidajar_status MCP tools.

What it does

pmset -a disablesleep 1   # kernel-level sleep prevention — lid-close safe
pmset -a disablesleep 0   # restore normal

Runs via a privileged helper (Unix socket) — no password prompts after first install.
