//! Descry Tool Core - Modern async-first tool framework
//!
//! Provides zero-cost, compile-time tool registration with modern Rust best practices.
//!
//! # Features
//!
//! - **Single async Tool trait** - No SyncTool/AsyncTool separation
//! - **Arc<ToolContext>** - No borrow checker hell, works across await points
//! - **Compile-time registration** - Using `inventory` for zero startup cost
//! - **Thread-local schema cache** - Generated once per type
//! - **Thread-safe** - `DashMap` for concurrent extensions
//! - **Error chaining** - `thiserror` with `#[source]` support
//! - **Multi-protocol adapters** - MCP, OpenAI, Anthropic built-in
//! - **Tower Service integration** - Middleware ecosystem support (optional)
//!
//! # Quick Start
//!
//! ```ignore
//! use descry_tool_core::{Tool, ToolContext, ToolError};
//! use serde::{Deserialize, Serialize};
//! use schemars::JsonSchema;
//! use std::sync::Arc;
//!
//! #[derive(Deserialize, JsonSchema)]
//! struct AddParams {
//!     a: i32,
//!     b: i32,
//! }
//!
//! #[derive(Serialize, JsonSchema)]
//! struct AddOutput {
//!     result: i32,
//! }
//!
//! struct AddTool;
//!
//! impl Tool for AddTool {
//!     type Params = AddParams;
//!     type Output = AddOutput;
//!
//!     const NAME: &'static str = "add";
//!     const DESCRIPTION: &'static str = "Add two numbers";
//!
//!     async fn call(
//!         ctx: Arc<ToolContext>,
//!         params: Self::Params,
//!     ) -> Result<Self::Output, ToolError> {
//!         Ok(AddOutput {
//!             result: params.a + params.b,
//!         })
//!     }
//! }
//! ```
