1//! # AI-Optimized Terminal Session Management Library
2//!
3//! `ai-session` provides an advanced session management system designed specifically
4//! for AI agents and modern development workflows. It offers features beyond traditional
5//! terminal multiplexers like tmux, with a focus on AI context management, multi-agent
6//! coordination, and intelligent output handling.
7//!
8//! ## Key Features
9//!
10//! ### 🧠 AI-Optimized Session Management
11//! - **Token-efficient context handling**: Automatically manages conversation history with intelligent compression
12//! - **Semantic output parsing**: Understands command output types (build results, test outputs, error messages)
13//! - **Context-aware suggestions**: Provides intelligent next-action recommendations

20//! ### 🤝 Multi-Agent Coordination
21//! - **Message bus architecture**: Enables seamless communication between AI agents
22//! - **Task delegation**: Intelligent workload distribution across specialized agents
23//! - **Shared context**: Cross-agent knowledge sharing for improved efficiency
24//!
25//! ### 📊 Advanced Observability
26//! - **Decision tracking**: Records AI agent decision-making processes and outcomes
27//! - **Performance profiling**: Monitors resource usage and optimization opportunities
28//! - **Anomaly detection**: Identifies unusual patterns in agent behavior
29//!
30//! ### 🔒 Security & Isolation
31//! - **Capability-based security**: Fine-grained access control for agent actions
32//! - **Namespace isolation**: Secure separation between different agent sessions
33//! - **Rate limiting**: Prevents resource abuse and ensures fair usage
34//!
35//! ### 💾 Session Persistence
36//! - **State snapshots**: Save and restore session state for continuity
37//! - **Command history**: Complete audit trail of all executed commands
38//! - **Compression**: Efficient storage using zstd compression
39//!
40//! ## Quick Start
41//!
42//! ```rust,no_run
43//! use ai_session::*;
44//! use anyhow::Result;
45//!
46//! #[tokio::main]
47//! async fn main() -> Result<()> {
48//! // Create session manager
49//! let manager = SessionManager::new();
50//!
51//! // Configure session with AI features
52//! let mut config = SessionConfig::default();
53//! config.enable_ai_features = true;
54//! config.context_config.max_tokens = 4096;
55//!
56//! // Create and start session
57//! let session = manager.create_session_with_config(config).await?;
58//! session.start().await?;
59//!
60//! // Execute commands
61//! session.send_input("echo 'Hello AI Session!'\n").await?;
62//! let output = session.read_output().await?;
63//!
64//! println!("Output: {}", String::from_utf8_lossy(&output));
65//!
66//! // Clean up
67//! session.stop().await?;
68//! Ok(())
69//! }
70//! ```
71//!
72//! ## Multi-Agent Example
73//!
74//! ```rust,no_run
75//! use ai_session::*;
76//! use ai_session::coordination::{MultiAgentSession, AgentId};
77//! use anyhow::Result;
78//! use std::sync::Arc;
79//!
80//! #[tokio::main]
81//! async fn main() -> Result<()> {
82//! let coordinator = Arc::new(MultiAgentSession::new());
83//! let manager = SessionManager::new();
84//!
85//! // Create specialized agents
86//! let mut frontend_config = SessionConfig::default();
87//! frontend_config.agent_role = Some("frontend".to_string());
88//! frontend_config.enable_ai_features = true;
89//!
90//! let frontend_session = manager.create_session_with_config(frontend_config).await?;
91//! let frontend_id = AgentId::new();
92//!
93//! coordinator.register_agent(frontend_id.clone(), frontend_session)?;
94//!
95//! // Agents can now coordinate through the message bus
96//! println!("Multi-agent system ready!");
97//!
98//! Ok(())
99//! }
100//! ```
101//!
102//! ## Architecture Overview
103//!
104//! The library is organized into several key modules:
105//!
106//! - [`core`] - Core session management and lifecycle
107//! - [`context`] - AI context and conversation history management
108//! - [`coordination`] - Multi-agent communication and task distribution
109//! - [`output`] - Intelligent output parsing and semantic analysis
110//! - [`security`] - Access control, isolation, and rate limiting
111//! - [`observability`] - Monitoring, decision tracking, and performance analysis
112//! - [`persistence`] - Session state storage and recovery
113//! - [`integration`] - Compatibility layers (tmux, VS Code, etc.)
114//!
115//! ## Performance Characteristics
116//!
117//! - **Memory Efficient**: Context compression reduces memory usage by ~70%
118//! - **Context Optimized**: Intelligent history management for efficient session handling
119//! - **Low Latency**: Message passing adds <100ms coordination overhead
120//! - **Scalable**: Supports 100+ concurrent agent sessions
121//!
122//! ## Compatibility
123//!
124//! - **Cross-platform**: Works on Linux, macOS, and Windows
125//! - **tmux Compatible**: Drop-in replacement with migration tools
126//! - **IDE Integration**: VS Code extension support built-in
127//! - **CI/CD Ready**: Designed for automated workflows
