//! ThinkTool MCP Handlers
//!
//! MCP tool implementations for ReasonKit ThinkTools, exposing
//! structured reasoning capabilities to AI agents via MCP.
//!
//! ## Available Tools
//!
//! | Tool | Description | Profile |
//! |------|-------------|---------|
//! | `gigathink` | Expansive creative thinking (10+ perspectives) | `--creative` |
//! | `laserlogic` | Precision deductive reasoning with fallacy detection | `--balanced` |
//! | `bedrock` | First principles decomposition | `--deep` |
//! | `proofguard` | Multi-source verification (3+ sources) | `--paranoid` |
//! | `brutalhonesty` | Adversarial self-critique | `--paranoid` |
//!
//! ## Usage
//!
//! ### Quick Registration (Recommended)
//!
//! Use `register_thinktools()` to register all 5 tools at once:
//!
//! ```rust,ignore
//! use reasonkit::mcp::{McpServer, register_thinktools};
//!
//! let server = McpServer::new(...);
//! register_thinktools(&server).await;  // Registers all 5 ThinkTools
//! ```
//!
//! ### Individual Handler Registration
//!
//! Register specific tools using individual handlers:
//!
//! ```rust,ignore
//! use reasonkit::mcp::{ThinkToolHandler, GigaThinkHandler, McpServer};
//! use std::sync::Arc;
//!
//! let server = McpServer::new(...);
//!
//! // Register only GigaThink
//! server.register_tool(
//!     ThinkToolHandler::gigathink_tool(),
//!     Arc::new(GigaThinkHandler::new())
//! ).await;
//! ```
//!
//! ### Combined Handler (Legacy)
//!
//! For backward compatibility, use `ThinkToolHandler` with `_tool` routing:
//!
//! ```rust,ignore
//! use reasonkit::mcp::{ThinkToolHandler, ToolHandler};
//!
//! let handler = ThinkToolHandler::new();
//! let tools = handler.tool_definitions();
//!
//! // Register with MCP server
//! for tool in tools {
//!     server.register_tool(tool, Arc::new(handler.clone()));
//! }
//! ```
