//! Memory tool for Anthropic-specific agent memory.
//!
//! This module provides a simple builtin tool type for referencing
//! Anthropic's memory feature at the API level.

/// This is a simple marker struct used to indicate that the agent

/// # Example
///
/// ```
/// use serdes_ai_tools::builtin::MemoryTool;
///
/// let memory = MemoryTool::new();
/// assert_eq!(memory.kind, "memory");
/// ```
