The most common mistake in agent architecture is treating autonomy as a binary: either the agent is fully autonomous, or a human does the work. In practice, most production workflows need something in between — and the Human Gate pattern is how we implement it.
What a Human Gate is
A Human Gate is a defined point in an agent workflow where the agent pauses, presents what it has determined to a human reviewer, and waits for approval before proceeding. The agent does the work of analysis and preparation; the human makes the consequential decision; the agent then executes.
When to insert a gate
Gates belong at decisions that are:
- Irreversible — sending a payment, deleting a record, making a commitment on behalf of the business
- High-value — actions affecting large amounts of money, sensitive data, or key relationships
- Novel — cases that do not fit a pattern the agent has handled reliably before
- Externally visible — communications to customers, partners, or regulators
Implementation pattern
The agent workflow pauses and creates a review task: a structured summary of what it observed, what it is proposing to do, and why. The reviewer sees the agent's reasoning, approves or modifies the proposed action, and the agent executes. The full decision trail — what the agent proposed, what the human changed, what was ultimately done — is logged.
The practical outcome
In our experience, agents with well-designed Human Gates have significantly lower error rates than fully autonomous agents and require dramatically less human time than fully manual processes. The gate adds friction at exactly the right points — where friction is appropriate — while allowing the agent to handle the volume that makes automation worthwhile.
The goal is not to limit the agent. It is to concentrate human attention where it matters most. Human Gates are the mechanism that makes that concentration possible.
