# Human Gate
A point in an agent loop where the model pauses and waits for human input before continuing.

## Definition
A human gate is a point in an agent loop where the model presents a result or proposal and waits for human input before continuing. Human gates are specified in skills — a skill defines where in the workflow the agent should stop and ask. The model produces a response with no tool calls, which ends the current loop and returns control to the user. Human gates are where the user exercises judgment while the agent handles the mechanical work.
