5. The human-in-the-loop (HITL) agent

The fifth pattern is the one I think we’ll see increasingly more of in the future. While many see “full automation” as the goal, the right target is actually to let the agent handle the 80% of a task that is mechanical, while preserving human judgment at the most critical moments. This is achievable via human-in-the-loop (HITL) agents. According to Moody’s, 42% of compliance professionals believe that human oversight is mandatory, and I agree: AI should run right, by getting approval and review before any sensitive business action is taken. HITL is the architecture that can help turn a skeptical team into an enthusiastic one.

A regional health system I worked with uses a HITL agent for prior-authorization letters. The agent assembles the clinical evidence, drafts the letter against the relevant payer’s criteria, and routes it to a nurse case manager for review inside the existing workflow tool. The nurse approves, edits or rejects in seconds rather than minutes, and every edit helps make the next draft better. A property management company uses a HITL agent to run its maintenance work orders. When a tenant emails about a problem (an HVAC unit that died overnight, say), the agent pulls the structured details (tenant, unit, issue type, urgency), matches the job to the right vendor from the directory, and drafts the work order.

A team member approves it in Slack before anything goes out. From there the agent emails the vendor with the full order, confirms with the tenant that someone is on the way and updates Airtable, closing the loop completely.
