This is a good discussion of these principles. Largely inspired by Emacs, I built an interpreted lisp which runs in a web server and stores the AST Postgres. It gives me this kind of malleable computing and a Lispy feel with very little overhead. Instead of calling an API, agents can just use functions in a REPL. They can also write new views and improve the program if they run into an issue. Honestly, pretty amazing stuff. Being able to design a program specifically for the workflow I want is pretty neat. There's some vibeslop jank, but Emacs is a little bit jank too.

There’s an interesting middle ground: not fully malleable software, where the end user has full customisation ability but requires full programming skill, but eg the Unix tool model where prebuilt utilities can be composed with a simple syntax. Pre-existing (or importable) ELisp functions are kinda similar, just a slightly higher level of user skill.

JavaScript did this for the Web back in the day. I work on a malleable git-compatible SCM right now. First I put all the performance-critical parts into a native lib, then happily built my own git(hub) in JavaScript. Tastes differ, someone else may build it completely differently. I believe this is the right architecture for the LLM age. https://github.com/gritzko/beagle

AutoHotkey adds a malleable computing layer to Windows.

OP here. Happy to answer any questions about my post in this thread.

I love emacs

Yet another one rediscovers the way Lisp machines, Smalltalk, Cedar and Oberon were envisioned, and we never really got it in mainstream computing. Nice article.

This is nice but not even a mention of the rather robust existing solution here with Magit Forge? https://github.com/magit/forge

Useless without local/remote sync. Also kind of obvious is the preferability of composeable UNIX programs over heavily locked down monoliths, hardly calling for a Fred Brooks style exegesis.
