Score: 3.5/10 (Innovation: 4, Technical: 3, Documentation: 2, Utility: 5)

A lightweight pattern for making AI coding agents from different vendors (Claude, Codex, Gemini) interact through CLI resume modes instead of paid APIs, enabling multi-agent workflows without additional dependencies. It's interesting as a practical hack that leverages existing subscription plans to get diverse model perspectives on coding tasks.

Target audience: backend devs
