Letting Copilot Manage Qwen: A Simple Experiment in Agent-to-Agent CLI Collaboration

The author experiments with using GitHub Copilot as a manager agent to direct the Qwen CLI agent for coding tasks, leveraging the open-relay (oly) tool to enable plain CLI-based agent-to-agent interaction without custom integrations. The experiment involved having Copilot supervise Qwen to clean up a WeChat hook .NET project, write documentation, and add a browser-opening feature for QR code authentication. The key insight is that large language models can understand TUI output and send appropriate instructions, making multi-agent CLI collaboration feasible without specialized protocols.
