The `AgentTool` class provides the following attributes for customizing its behavior:

* **skip\_summarization** (Python/TypeScript) / **skipSummarization** (Kotlin/Java): (boolean) If set to True, the framework will **bypass the LLM-based summarization** of the tool agent's response. This can be useful when the tool's response is already well-formatted and requires no further processing.
* **skip\_summarization: bool:** If set to True, the framework will **bypass the LLM-based summarization** of the tool agent\'s response. This can be useful when the tool's response is already well-formatted and requires no further processing.
* **propagate_grounding_metadata: bool:** (default: `False`) When set to `True`, the tool will automatically forward any grounding metadata (such as Google Search or Vertex AI Search citations) generated by the sub-agent up to the parent agent's session state. This ensures that citations are preserved when using specialized search agents as tools.
