1//! # Pawan (पवन) - Self-Healing CLI Coding Agent
2//!
3//! Core library for the Pawan coding agent. Provides:
4//!
5//! - **Agent**: Tool-calling loop engine with multi-provider LLM support
6//! - **Tools**: File operations, bash execution, git, search
7//! - **Healing**: Automatic detection and repair of compilation errors, test failures, warnings
8//! - **Config**: TOML-based configuration with provider/model management
9//!
10//! ## Architecture
11//!
12//! - `pawan-core` (this crate): Library with zero dirmacs dependencies
13//! - `pawan-cli`: Binary with TUI and CLI interface
14//!
15//! ## Quick Start
16//!
17//! ```bash
18//! pawan                    # Interactive TUI mode
19//! pawan heal               # Auto-fix compilation issues
20//! pawan task "description" # Execute a coding task
21//! pawan run "prompt"       # Headless single-prompt execution
22//! ```
