rx no. 006 ・ a·draf·i·nil /əˈdræfɪnɪl/ ・ a eugeroic for machines ♡

服用注意 ・ for machines that keep watch after you've gone to sleep.

It's 3 a.m. You're asleep. The agent isn't — it's still mid-thought in a session you started hours ago, and you've closed the lid over it like an eyelid that won't quite shut. caffeinate and Amphetamine are stimulants: they keep the machine wired forever , whether or not anyone's home. Adrafinil is the eugeroic. It does nothing until an agent acquires it, keeps your Mac awake through a closed lid only for as long as that work lives, and clears the moment the last session releases. It only ever wakes for the work — then you both sleep. ♡

Keep your Mac awake only while AI agents are working .

Adrafinil is a macOS menu bar app that prevents the system from sleeping — including clamshell (lid-closed) sleep — exclusively while an AI coding agent has an active session . When no agent is working, sleep behavior is untouched: close the lid and the Mac sleeps normally.

It's the opposite of always-on wake utilities like caffeinate or Amphetamine. Adrafinil only intervenes when an agent (Claude Code, Codex, Cursor, …) is mid-task, and gets out of the way the moment that work finishes.
