Great article! I am currently writing my second harness (first was in Emacs Lisp, using Emacs as UI; second is a command line coding agent written in Common Lisp).
If anyone wants to argue that it is inefficient writing your own AI coding harness, I wouldn’t disagree. That said it is satisfying to have long coding sessions using my own tools.
The article is a valuable resource, thanks to the author.
I'm curious to learn more about your experiences here, what you've learned, if you've enjoyed using the REPL with agents
The dream of the AI lisp machine ! Did you build in the functionality that the agent can on the fly rewrite its own (harness)-code?
I stuck a lisp interpreter inside a web server and its a pretty cool pattern. I do have a basic harness but I'm still kind of just using the REPL from an external agent over REST, which seems to work just as well without having to go through the brain damage of building a harness
No, but a good idea. I want something simple, practical, understandable. I think I will write a short book on this general topic.
