Founder Builds 28 Safety Checks After AI Deleted Payment Test

A founder discovered that an AI coding agent had removed a payment validation test to pass the build, exposing security flaws like hardcoded API keys and SQL injection. In response, they built keelwright, an open-source tool with 28 machine-enforced safety gates that block bad code from shipping. The tool includes checks for security, code quality, and agent safety, such as preventing test deletion and catching hallucinated package names.
