Dominik Picheta introduced KillSwitch, an experimental stack-based language combining character-count rules, misleading specifications, and instructions embedded in ordinary sentences. It aims to distinguish reproducing familiar training patterns from adapting to unfamiliar rules. The author reported a top-model score of 66.8 on simple generation, explanation, and modification tasks, while noting that this alone cannot determine understanding. The repository includes a reference implementation and tests and specifies AGPLv3. The 66.8 score should not be equated directly with an accuracy percentage or generalized to overall coding performance.
