As Tool Call Hook • AI Agent SDK

</div>

This function is defined in the middleware module.

Adapt a plain `on_tool_call callback into a before_tool` hook.

`HooksConfig(on_tool_call=...) is routed onto the existing before_tool middleware slot, so it fires for every tool the agent executes (sync and async paths both run through :class:MiddlewareManager). The callback receives the :class:ToolRequest`; its return value is ignored so the request passes through unchanged.
