# Agent operating procedure

A written procedure that tells an AI agent how to handle a type of work, encoded from the standard operating procedures a finance team already follows.

Every AR team has procedures: when to escalate, which customers get a call instead of an email, what documentation a dispute needs. Many live in people's heads or in documents nobody has updated.

Writing them as agent operating procedures makes an agent's behavior explicit and reviewable. When policy changes, the procedure changes, and the agent follows the new version.
