agnix-lsp 0.10.2

#![allow(clippy::collapsible_if, dead_code)]

//! # agnix-lsp
//!
//! Language Server Protocol implementation for agnix.
//!
//! Provides real-time validation of agent configuration files in editors
//! that support LSP (VS Code, Neovim, Helix, etc.).
//!
//! ## Features
//!
//! - Real-time diagnostics on file open, change, and save
//! - Quick-fix code actions for automatic repairs
//! - Hover documentation for configuration fields
//! - Supports all agnix validation rules
//! - Maps agnix diagnostics to LSP diagnostics
//!
//! ## Usage
//!
//! Run the LSP server:
//!
//! ```bash
//! agnix-lsp
//! ```
//!
//! The server communicates over stdin/stdout using the LSP protocol.
