Tool Search Tool
A mechanism in agent systems that retrieves tool definitions on demand, using semantic search to recall matching tools from a hidden tool library. It avoids injecting the full set of tool schemas into the context, which would otherwise waste tokens.

The OpenAI Agents SDK provides two mechanisms, Tool Search Tool and Tool Namespace, to reduce the Token consumption caused by tool definitions.
When the defer_loading parameter is set to True, the tool is completely invisible to the model, and it only enters the model context when the Tool Search Tool finds it.
