Key features
What Adrafinil does at a glance.
Agent-aware, not always-on. Sleep is blocked only while ≥1 agent session holds an assertion. Zero sessions → normal sleep, including lid-close
Sub-50ms CLI
Adrafinil acquire / release are called from agent hooks and round-trip to the daemon in under 50ms, so they never stall an agent's workflow
Reference-counted assertions
Overlapping sessions stack cleanly; sleep unblocks only when the last one releases
Thermal cutout
If skin/CPU temperature crosses threshold while the lid is closed, all assertions are force-released so a bag-bound Mac can't cook itself
Idle release
Assertions whose owning process has died or gone CPU-idle for N minutes are dropped automatically
Process sniffing (optional)
The daemon can auto-acquire when it sees a known agent binary running, even without hooks installed
