-The following example demonstrates how to use the `beforeToolCallback` and `afterToolCallback` hooks in the ADK `LlmAgent` to implement pre and post processing logic. Specifically, it shows how to intercept tool calls to enforce business policies (blocking invalid actions) and enrich tool outputs (adding loyalty points) before they return to the model.

+You can also add model-level (`beforeModelCallback`, `afterModelCallback`) and agent-level (`beforeAgentCallback`, `afterAgentCallback`) hooks to intercept messages at different stages of the execution loop.
