- Implement #[prompt], #[prompt_router], and #[prompt_handler] macros - Add automatic JSON schema generation from Rust types for arguments - Support flexible async handler signatures with automatic adaptation - Create PromptRouter for efficient prompt dispatch - Include comprehensive tests and example implementation This enables MCP servers to provide reusable prompt templates that LLMs can discover and invoke with strongly-typed parameters, similar to the existing tool system but optimized for prompt use cases. 🤖 Generated with Claude Code Co-Authored-By: Claude <[email protected]>

It looks It seems that rmcp-marcos lacks detailed documentation here, could you add that? |

This PR introduces a comprehensive prompt system for the Rust SDK, adding
#[prompt],#[prompt_router], and#[prompt_handler]macros that enable MCP servers to provide reusable prompt templates.Motivation and Context
This change enables MCP servers to define discoverable prompt templates that LLMs can invoke with type-safe parameters. It provides a standardized way to define, route, and handle prompts, improving the interaction between LLMs and server-side prompt templates.
