Could you build this?

Partial A lightweight local-first desktop editor can be created easily, but achieving sub-second cold starts and seamless bidirectional IPC with external CLI agents/MCP servers requires non-trivial desktop systems integration.

What it would actually take: The app uses a native Rust/Tauri framework with low-memory text data structures (e.g., piece tables or ropes) and local file watchers. The tricky component is designing clean Unix socket / Model Context Protocol (MCP) handlers and file-locking mechanics so external agents and human typists do not overwrite each other during concurrent edits.
