//! # GroqCloud Tool Use Types
//!
//! Types for GroqCloud's three-tier tool ecosystem:
//! - **Built-in tools**: `web_search`, `visit_website` (server-side execution on compound models)
//! - **Remote MCP**: Third-party MCP server integration via server-side orchestration
//! - **Local tool calling**: Standard function calling (uses the existing `ToolDefinition`)
//!
//! # Example
//! ```rust,ignore
//! use qai_sdk::groqcloud::tools::*;
//!
//! // Built-in web search tool
//! let tools = vec![
//!     GroqTool::builtin_web_search(None),
//!     GroqTool::builtin_visit_website(),
//! ];
//! ```
