I built a programming language that LLMs can't use

A developer created KillSwitch, an esoteric programming language deliberately designed to be difficult for LLMs and coding agents to use, while remaining accessible to humans. The language incorporates features that exploit LLM weaknesses, such as requiring precise character counting in identifiers, embedding misleading information in its specification, and using largely irrelevant text as "noise" to obscure actual code. KillSwitch is a stack-based language with fundamental constructs like functions and variables, but its adversarial design aims to test whether LLMs can truly understand code or merely reproduce patterns from their training data.
