Score: 5.8/10 (Innovation: 5, Technical: 7, Documentation: 6, Utility: 5)

A reverse-engineered Python client that mimics Cursor editor's tab completion (Copilot++) by directly calling its internal Connect RPC API. It's interesting because it bypasses the official editor, enabling programmatic access to the completion service for automation or integration into other tools.

Target audience: backend devs
