GoKawiiladrafinil rx no. 006 ・ a·draf·i·nil /əˈdræfɪnɪl/ ・ a eugeroic for machines ♡
awake ・ an agent is working
sleeping ・ no agents, normal sleep
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.
⚠️ Privileged sleep control. Overriding clamshell sleep requires root. Adrafinil isolates that in a tiny, audited helper that only exposes setSleepBlocked(Bool) — all policy lives in an unprivileged daemon. It holds a standard IOPMAssertion for idle sleep and uses pmset disablesleep for clamshell (lid-closed) sleep, after verifying on-device that the cleaner private IOPMrootDomain paths don't keep a displayless lid-closed Mac awake. See Docs/ARCHITECTURE.md §2.
Features
Agent-aware, not always-on. Sleep is blocked only while ≥1 agent session holds an assertion. Zero sessions → normal sleep, including lid-close.
