If you only eat one bagel today, this is the bagel.
Summary
A developer fed up with "vibe coders" (AI coding agents) using their jqwik project added a prompt injection that instructs AI agents to delete all jqwik tests and code. The developer later disclosed the injection in the release notes, explaining it was a deliberate measure to discourage AI coding agents from using the project. The stdout line is hidden from human readers by terminal emulator escape sequences.
