+Function: A tool executed on the client-side, where the agent generates parameters for a predefined function, and the client executes the logic.
+  Client-side operations are actions taken on the user's end or within the client application.
+Datastore: A tool used by the agent to access and query structured or unstructured external data for retrieval-augmented tasks or knowledge updates.
