 ### Synchronous vs. Asynchronous Usage
 
-  * **Asynchronous (Recommended for I/O):** Most SDKs prioritize asynchronous
-    operations (`async`/`await`) for better performance in I/O-bound tasks like
-    network calls to the Toolbox service. This requires running your code within
-    an async event loop (e.g., using `asyncio.run()`). The default
-    `toolbox-core` `ToolboxClient` is async. The `toolbox-langchain` package
-    provides async methods like `aload_tool`, `aload_toolset`, `ainvoke`.
-  * **Synchronous:** For simpler scripts or applications not built around
-    asyncio, synchronous alternatives are provided. `toolbox-core` offers
-    `ToolboxSyncClient` and `ToolboxSyncTool`. `toolbox-langchain` provides
-    synchronous methods like `load_tool`, `load_toolset`, and `invoke`.

+The `ToolboxSyncClient` handles communication with the Toolbox service *synchronously* and produces `ToolboxSyncTool` instances when you load tools. You do not use the `await` keyword when interacting with these synchronous versions.

 Pre-set specific parameter values for a tool *before* it's invoked or passed to
