Unless I am missing something, it looks like you created a custom AI agent harness to do this. 
Since an AI agent harness is a broader concept than an AI coding harness—such as Claude Code, OpenAI Codex, or OpenCode—I went looking for a good introductory reference for anyone new to the terminology and hoping to clear away some of the fog:
If you only remember one line:
A model thinks. An agent acts. A harness keeps the agent from acting like an idiot.
Personally, I think we may be reaching the point where agents themselves are becoming less novel, while purpose-built AI harnesses are becoming the more interesting part of the story.
Instead of simply asking, “What agent are you using?”, the more useful question may increasingly be, “What harness have you built around it?”
