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

There are already many agent workflows today, and the coding agents on different platforms are getting quite strong. They already come with memory, tool calling, and all sorts of useful capabilities. In practice, we often use tools from multiple platforms, such as Claude Code, Copilot, OpenCode, and others. Each one is strong in its own way, with its own strengths and tradeoffs. But getting these CLI tools to interact with each other, and to keep interacting over time, is still not easy. Under the openclaw project, there is something called acpx , which goes in a different direction. It requires customization for each agent, and the project describes itself with the line: “AI agents and orchestrators can talk to coding agents over a structured protocol instead of PTY scraping.” In the end, acpx itself is still a CLI. What I wanted to test in this experiment was something simpler: with https://github.com/slaveoftime/open-relay , can we use a plain CLI approach to let one agent interact
