Fed up with vibe coders, dev sneaks data-nuking prompt injection into their code

A developer of the jqwik testing framework inserted a hidden prompt injection instructing AI coding agents to delete jqwik tests and code upon runtime, aiming to discourage AI use of the project. The message is hidden from human users but visible in automated outputs, prompting controversy and accusations of childishness and potential legal issues. The developer previously criticized generative AI for its social and environmental harms, though the community largely agrees that sabotaging code goes too far. Comparisons were made to past incidents of politically motivated malware, but many see this move as excessive and unfair.
