Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Executes one delegated call: budget check, sub-agent generation, result validation, accounting.

The runner is what makes a sub-agent a tool rather than a method call. It answers to the calling model in the model's own terms — a refused call comes back as a structured result the model can reason about, not as an exception that ends the conversation.
