## AI overview

Rapid AI-assisted changes can leave duplicated logic, scattered business rules, inconsistent patterns, growing dependencies, and code that is harder to maintain--even when it runs and tests pass. The article lists seven warning signs, including repeatedly changed files, expanding conditionals, tests altered just to pass, and unexplained code. It recommends auditing one feature by tracing its Git history, mapping responsibilities, checking for duplicated behavior, reviewing tests and dependencies, and recording evidence before changing code. For fixes, it favors the smallest safe response, often incremental refactoring that separates responsibilities and preserves behavior. It also stresses verifying test expectations, documenting decisions, and giving AI assistants project architecture and conventions as context; generated code and review suggestions still need developer judgment. Its Express-style JWT example illustrates separate authentication, rate-limiting, and endpoint responsibilities, and warns that jwt.decode() does not verify a token signature.
