A consent gate is a deliberate pause point inserted into an agent workflow that halts execution until a human reviewer explicitly approves the proposed next action. Consent gates are used for high-stakes, irreversible, or sensitive operations — such as deploying code to production, sending emails on behalf of a user, or making financial transactions. They represent a structured form of human-in-the-loop control that balances agent autonomy with human oversight, and are typically enforced by the agent harness rather than the model itself.
