What they did
The poster, u/jvon5808, wanted a language for writing AI agents in which every keyword is an internet meme: pepe declares an agent, npc a function, thonk calls a model, apu asks a human, yolo marks an irreversible action and sus marks untrusted data. They came up with the concept and the keyword list, then handed the build to Claude Code. It wrote the lexer, parser, interpreter and a CLI with a check command for static analysis and an explain command that turns meme code into plain English. The poster described how untrusted data should be handled and Claude Code built the tracking and static checks for it. It also wrote the test suite and used Playwright to record the animated examples in the README.
How it went
The result is an open-source, MIT-licensed language on GitHub that runs locally, supports several agents and parallel tasks, and can call Claude or local models through Ollama. It ships with 34 tests. The poster calls the sus and yolo safety system the hardest part and says the project is still experimental. No time or cost is given. Commenters mostly found it funny.
Worth knowing
The joke has a real idea inside it: anything fetched from the web is tainted, and the runtime refuses to let it reach an irreversible action until code explicitly marks it as reviewed. One commenter pointed out that meme keywords make grepping and error messages harder to read, for people and models alike.
