systematic-bug-diagnosis

Guides a repeatable five-pass loop for fixing broken code: make the failure reproduce reliably, shrink the search space using the stack trace and data flow, name the underlying cause instead of the symptom, apply a minimal targeted repair, and prove it with type checks, tests, and the original reproduction. Includes playbooks for TypeScript compiler errors, runtime crashes, HTTP and API failures, React state bugs, performance bottlenecks, and module resolution problems, plus a hygiene checklist covering logging and regression tests. Use when the user reports an error, crash, failing build, failing test, or unexpected behavior, or asks why something stopped working. Not for writing new features, stylistic refactoring, or dedicated security audits.
