The full story

Geoffrey Huntley ran Claude in a loop for three months, and it created "cursed", a complete programming language whose keywords are Gen Z slang, with an interpreter and compiler. Simon Willison wrote about it as a striking example of what long-running autonomous agents can produce.

Steal the prompt

Hey, can you make me a programming language like Golang but all the lexical keywords are swapped so they're Gen Z slang?
The opening prompt, as Geoffrey Huntley shared it; Claude then ran in a loop for months.

Prompt & Solder

An independent community project. Not affiliated with Anthropic.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count).
