anyclaw-sdk-tool 0.2.10

//! Tool SDK for anyclaw.
//!
//! Provides the [`Tool`] trait for building MCP-compatible tools and
//! [`ToolServer`] for serving them over stdio.
//!
//! # Stability
//!
//! This crate is **unstable** — APIs may change between releases.
//! Enums marked `#[non_exhaustive]` will have new variants added; match arms must include `_`.
