//! Agent module for interactive AI-powered CLI assistance
//!
//! This module provides an agent layer using the Rig library that allows users
//! to interact with the CLI through natural language conversations.
//!
//! # Features
//!
//! - **Conversation History**: Maintains context across multiple turns
//! - **Automatic Compaction**: Compresses old history when token count exceeds threshold
//! - **Tool Tracking**: Records tool calls for better context preservation
//!
//! # Usage
//!
//! ```bash
//! # Interactive mode
//! sync-ctl chat
//!
//! # With specific provider
//! sync-ctl chat --provider openai --model gpt-5.2
//!
//! # Single query
//! sync-ctl chat --query "What security issues does this project have?"
//! ```
//!
//! # Interactive Commands
//!
//! - `/model` - Switch to a different AI model
//! - `/provider` - Switch provider (prompts for API key if needed)
//! - `/help` - Show available commands
//! - `/clear` - Clear conversation history
//! - `/exit` - Exit the chat
