devil's advocate is a cli tool that vibe checks your code. everyone uses ai to generate scripts now, but they usually break on edge cases. this tool uses gemini to write hostile tests that purposefully crash your app, then uses the error logs to auto-fix the source code. basically, it breaks your code so you don't have to, then patches it instantly. it turns "vibe coding" into actual working software.
