Away from keyboard. A working pattern where the user kicks off a session and leaves the agent to run unattended. The throughput multiplier of AI coding — many AFK sessions can run in parallel while you sleep, eat, or work on something else. Usually requires a permissive permission mode plus sandboxing to be safe.
Avoid: "background agent" — centers the machine ("running in the background") rather than the human pattern ("user has walked away"). AFK is the load-bearing fact: the user isn't watching.
Usage:
"I'm running this AFK — three sandboxed agents on the refactor, reviewing the PRs in the morning."
"Bypass permissions?"
"Yeah, read-only filesystem, no network."
