a3s-code-core 1.8.3

//! A3S Code Core Library
//!
//! Embeddable AI agent library with tool execution capabilities.
//! This crate contains all business logic extracted from the A3S Code agent,
//! enabling direct Rust API usage as an embedded library.
//!
//! ## Quick Start
//!
//! ```rust,no_run
//! use a3s_code_core::{Agent, AgentEvent};
//!
//! # async fn run() -> anyhow::Result<()> {
//! // From a config file path (.hcl or .json)
//! let agent = Agent::new("agent.hcl").await?;
//!
//! // Create a workspace-bound session
//! let session = agent.session("/my-project", None)?;
//!
//! // Non-streaming
//! let result = session.send("What files handle auth?", None).await?;
//! println!("{}", result.text);
//!
//! // Streaming (AgentEvent is #[non_exhaustive])
//! let (mut rx, _handle) = session.stream("Refactor auth", None).await?;
//! while let Some(event) = rx.recv().await {
//!     match event {
//!         AgentEvent::TextDelta { text } => print!("{text}"),
//!         AgentEvent::End { .. } => break,
//!         _ => {} // required: #[non_exhaustive]
//!     }
//! }
//! # Ok(())
//! # }
//! ```
//!
//! ## Architecture
//!
//! ```text
//! Agent (facade — config-driven, workspace-independent)
//!   +-- LlmClient (Anthropic / OpenAI)
//!   +-- CodeConfig (HCL / JSON)
//!   +-- SessionManager (multi-session support)
//!         |
//!         +-- AgentSession (workspace-bound)
//!               +-- AgentLoop (core execution engine)
//!               |     +-- ToolExecutor (14 tools: 11 builtin + 3 skill discovery)
//!               |     +-- LlmPlanner (JSON-structured planning)
//!               |     +-- HITL Confirmation
//!               +-- HookEngine (8 lifecycle events)
//!               +-- Security (sanitizer, taint, injection detection, audit)
//!               +-- Memory (episodic, semantic, procedural, working)
//!               +-- MCP (JSON-RPC 2.0, stdio + HTTP+SSE)
//!               +-- Cost Tracking / Telemetry
//! ```
