This crate enables extending the agent's behavior through a flexible hook system. It allows various parts of the application to emit events that plugins can intercept and respond to.

Features

Lifecycle Hooks: Register callbacks for key agent events (session start, tool execution, response generated).
Synchronous & Asynchronous: Supports both immediate and future-based hook handlers.
Priority-Based Execution: Fine-grained control over the order in which hooks are processed.

Common Hooks

on_session_start: Setup tasks when a new conversation begins.
before_tool_execution: Validate or modify tool arguments before they run.
after_tool_execution: Process or log tool results.
on_message_received: Intercept incoming user messages.
