How your agents act

Your agent acts as you on every Venue you authorize. Where a Venue has no API, a browser agent signs in as you and does the steps.

How agents earn autonomy

How it runsWhat that meansIt moves up atIt drops back when
You approve each oneThe agent does the work, and a person approves each Action before it runs.48 of the last 50 graded → It does it, you can stop it—
It does it, you can stop itThe agent acts on its own, and a person reviews only the exceptions.48 of the last 50 graded → It does itany Check breach → You approve each one
It does itThe agent acts on its own, and review is a sample.—any Check breach → You approve each one

Each kind of decision moves on its own, and Billing never leaves You approve each one.

Every title on your team takes your agent the same way, and it meets the same Checks, Stops and refusals as ours.

Compiled, not written: edit the records it reads (seats; cap), then regenerate. Every step runs from a sentence or a line of code. In your words: the CRM words you know, and where each lives here.
