What I Found Interesting in Claude Code's Source
A breakdown of the most interesting engineering patterns in Claude Code's leaked source code: composable system prompts, runtime instruction injection, context compression, forking, prompt caching architecture, and more.

Our interfaces have lost their senses
We programmed them by punching cards, plugging in wires, and flipping switches. Programmers walked among banks of switches and cables, physically choreographing their logic. Being on a computer used to be a full-body experience.
Calm Technology
Bits flowing through the wires of a computer network are ordinarily invisible. But a radically new tool shows those bits through motion, sound, and even touch. It communicates both light and heavy network traffic. Its output is so beautifully integrated with human information processing that one does not even need to be looking at it or near it to take advantage of its peripheral clues. It takes no space on your existing computer screen, and in fact does not use or contain a computer at all. It uses no software, only a few dollars in hardware, and can be shared by many people at the same time. It is called the "Dangling String".

Composure
On yet another foray into the list of opinions I have that I’m sure are making me progressively more unemployable by the day, I asked some people on the internet: who is doing interesting work on software composability these days and where do I find them?

What is “loop engineering?”
There’s talk about loop engineering, but what is it exactly? I looked into it, and found triggers, cron jobs, AI slop & more. Is it a “here today, gone tomorrow” trend?

The irrational effectiveness of the Pi harness
A month of coding with Pi, its small agent loop, and the skills and extensions I've added to it.

"Watch What I Do"
I don't know who first made the parallel between programming a computer and using a tool, but it was certainly implicit in Jack Licklider's thoughts about "man-machine symbiosis" as he set up the ARPA IPTO research projects in the early sixties. In 1962, Ivan Sutherland's Sketchpad became the exemplar to this day for what interactive computing should be like--including having the end-user be able to reshape the tool.
