Then you are probably not interested in this work at all. It is meant to develop Lisp­—a language whose primary advantage in 2026 is ergonomics to humans, particularly a certain kind of human. If you're doing 100% agentic development, that advantage disappears and you might as well use something popular and statically typed, like Rust or TypeScript.

I beg to differ. Turns out, Lisp REPL - an actual, "true" REPL, not something like Python's (which is not the same), is an enormous multiplier for agentic workflows.

a) Lisp code can be very terse yet retain its readability - it never becomes cryptic like APL. Therefore, it's more token efficient. It was actually proven that Clojure is one of the most token-efficient "mainstreamish" PLs. https://martinalderson.com/posts/which-programming-languages...

b) When you give an LLM a closed loop system where it can evaluate code in a live REPL and observe the results, it stops guessing and starts reasoning empirically. Instead of predicting what code will do, it can run it, read the output, adjust, and iterate - the same way a skilled human developer works. Incremental evaluation of forms maps naturally to how an LLM generates tokens.

This isn't some theoretical hand-waving - I experience it every day - my WM on Mac is yabai that gets controlled via Hammerspoon, which uses Lua, which means I can use Fennel, which means I can use Lisp REPL. I would give the LLM a task, something to do with my app windows - it connects to the live REPL and starts analyzing, prototyping and poking into things interactively.

All my custom MCPs are written in babashka (Clojure) https://github.com/agzam/death-contraptions - whenever there's a problem or I need to improve my AI harness, LLM just does it from "inside out" and it takes less time and fewer tokens.

My main editor is Emacs - LLM can fully control it. I can make it change virtually any aspect of it. To load-test the MCP that does that, I made it play Tetris in Emacs. And not just to run it, but to play it for real - without losing. It was insane.

And of course, day-to-day I have to deal with non-Lispy, non-homoiconic languages more. And to be honest (even though of course I'm biased in this) static type systems is the exact thing in practice where their advantages feel like stop making any big difference. While Lisp REPL feels far more useful.

Technically, I think this is meant to develop Coalton, which is also statically typed and incredibly effective as a language for agents. All those ergonomic benefits that humans enjoy also allow AIs to develop lisp systems quite rapidly and robustly.

Not true. Are people not interested in archeology or history or museums? Denying such things as invalid is offensive. There are projects to reproduce things from ancient history like the Lycurgus cup.
