I watched AI destroy 3 weeks of work in 4 minutes. So I built something 😭

In a personal account on DEV Community, a developer describes an AI agent that, in four minutes, deployed code for a payment system that was missing input validation on the payment amount field, had the API key hardcoded directly in the source file, contained zero tests, had no rollback procedure, and logged user card numbers to the console. The code appeared clean with well-structured functions, but lacked all production safeguards. The author notes that AI agents commonly skip writing specifications, tests, security checks, rollback plans, safety evaluations for ML models, and quality gates for data pipelines, while sounding confident throughout. This incident motivated the author to build a tool to prevent such issues.
