onAfterStep

The onAfterStep event fires at the end of each iteration of the agent's execution loop, after the model has returned a response and any tools have been executed.

Usage

This event is the last hook to run before the agent either loops again (if tools were called) or transitions to idle.

It is useful for:

• Evaluating the result of the entire step.
• Cleaning up temporary states.
• Logging the total cost or duration of the step.

Payload Details

agent.onAfterStep(({ params, context }) => {
    console.log(`Finished step ${context.state.stepCount}. Moving to next state: ${context.state.status}`);
});
