Definition
An agent that runs without per-action human approval — often on a schedule or trigger.
In practice
Examples: a competitor monitoring agent that runs every Monday and posts to Slack. An AR chase agent that nudges overdue invoices on a cadence. Autonomy is fine when (a) actions are reversible, (b) there's a kill switch, (c) outputs are observable. Don't go autonomous on customer-facing actions without HITL.
