review-testability

What problem does it solve?

This Skill helps teams identify testability bottlenecks in code by surfacing patterns that tie business logic to IO, hide dependencies, or rely on hard-coded instantiation, enabling safer, more maintainable designs.

Core Features & Use Cases

• Read-only analysis: reviews code and provides findings without modifying source.
• Anti-pattern detection: spots common testability issues such as implicit dependencies, global state, and constructor work.
• Refactoring guidance: recommends patterns like functional core / imperative shell, explicit dependencies, and dependency injection to improve testability.
• Scoped reviews: supports file-path or diff-based scope to target relevant changes and contexts.

Quick Start

Specify the files or directories to review, or provide a diff against origin/main to scope the analysis.
