Agent runtime

Approval Gate

A point in an AI workflow where an action is suspended until a human reviews and approves, rejects, or modifies it.

Operating principle

Production AI is not a prompt. It is a system of context, tools, permissions, traces, evals, and feedback loops.

What it is

An approval gate is a deliberate pause point in an agent workflow where a high-impact action (sending an email, modifying production data, paying an invoice) is held until a human signs off. The agent prepares the action with full context; the human reviews; the workflow either proceeds, gets sent back, or is closed.

Why it matters

Not every AI decision is safe to ship unattended. Approval gates concentrate human judgment on the decisions that need it, leaving the agent to handle everything routine. Done right, they shift human review from 'check every output' (which collapses under volume) to 'check the cases that matter' (which scales).

How it works

The workflow declares which steps require approval, by what role, with what SLA. A pending decision lands in an approval inbox with the trigger event, the proposed action, the agent's reasoning, and the trace. The reviewer approves, rejects with reason, or modifies. Reject and modify events feed the eval set so similar cases become self-handling over time.
