What problem does it solve?

Prevents AI-assisted refactors from being applied to code that lacks sufficient tests, reducing regressions, debugging time, and accidental behavior changes.

Core Features & Use Cases

  • Pre-refactor safety check: Identifies scope, public API surface, and dependencies before any refactor is performed.
  • Coverage and quality assessment: Scans test targets for XCTest patterns, estimates coverage levels, and evaluates test quality (behavior vs. implementation).
  • Characterization test generation: When coverage is partial or missing, instructs or triggers generation of characterization tests to capture current behavior before refactoring.
  • Use case: Before migrating a repository module from CoreData to SwiftData or renaming public APIs, run this guard to ensure failing regressions will be caught by tests.

Quick Start

Run the testing-tdd-refactor-guard before asking the AI to refactor files like ItemManager.swift and ItemRepository.swift.
