What is an approval workflow?
An approval workflow is a control that stops an AI agent before it takes a consequential action, shows the proposed action to a named person, and proceeds only on that person’s approval. The agent does its research and drafting on its own, then reaches a step marked as requiring approval: posting a transaction, sending an email to a customer, changing a record in the ERP system, or deleting data. At that point the platform holds the action, notifies the approver, and waits. The approver sees what the agent wants to do, why, and the evidence behind it, and can approve, edit, or reject.
The workflow is defined in the platform, outside the model, as a rule attached to specific tools or conditions. It is the most common way to put a human in the loop with an agent without making the person do the work.
Why an approval workflow matters
Agents are good at the reading and drafting that make up most of a task and are not yet trustworthy for the final step that changes a system of record. An approval workflow lets a company get the value of the first part while a person keeps responsibility for the second. It also produces the record that governance frameworks ask for: a named approver, a timestamp, and the exact change that was authorized. Kirk Tech Solutions typically requires an approval step wherever an agent can write to a system of record, and relaxes it tool by tool once the agent has a track record on that action.
Approval workflow in practice
A building products distributor runs an agent on accounts payable. The agent matches each incoming vendor invoice to the purchase order and the receiving record, flags price or quantity differences, and prepares the invoice for posting. Invoices that match within tolerance post automatically, because that rule existed long before the agent. Anything with a variance goes to an approval queue, where an AP clerk sees the invoice, the purchase order, the receipt, and the agent’s explanation of the difference side by side. The clerk approves, edits the coding, or sends it back to the vendor. The approval screen is the clerk’s main tool, and the agent’s work is the preparation behind it.
What to watch for
- Show the approver the evidence, the proposed change, and the reason together; an approval button with no context trains people to click yes, which is automation bias in action.
- Watch approval times and override rates, since a queue nobody reviews within a day is a bottleneck and a queue nobody ever rejects is rubber-stamping.
- Define what happens on timeout: the action should expire or escalate, never execute by default.
- Make the approval record immutable and link it to the agent’s trace in the audit log.
