lspf gives Rust language servers a second life in agent tools

Field notes

The site models a hover request as a seven-step sequence: admission, panic isolation, tracing, concurrency control, route selection, handler execution, and response encoding. Its framework supplies synchronized documents, notebooks, workspace roots, configuration, and client connection state through handler context, while transports include stdio, TCP, WebSocket, browser, and Node workers. Agent hosts are described as reusing the same LSP features through a typed client, with tool choice and model decisions left to the host.
