Safe changes are auto-applied, while risky changes require confirmation. Based on twelve classic engineering books, it triggers when users want to fix everything or clean up the whole project in a single command.

Reviews existing test suites for structural problems like brittleness, mock abuse, coverage illusions, slow runs, and poor readability, drawing on twelve classic engineering books such as xUnit Test Patterns and Working Effectively with Legacy Code.
