maintainability-code-review

What problem does it solve?

Identifies and remedies maintainability issues in code that is functionally correct, enabling teams to improve readability, structure, and long-term quality without introducing bugs.

Core Features & Use Cases

• Dead / Compatibility-Only Code: Detects stale or obsolete branches, feature flags that are always on/off, and shim layers, enabling safe removal.
• Duplicate / Redundant Code: Flags repeated logic and opportunities to extract shared utilities to reduce drift.
• Hard-Coded Values / Magic Strings: Highlights domain-value literals that should be centralized for configurability and consistency.
• Naming Quality & Single Responsibility: Audits naming accuracy and ensures functions/classes have a single, clear responsibility.
• Error Handling Consistency: Promotes uniform and contextual error handling across modules.
• Dependency Direction & Visibility: Checks for inappropriate module dependencies and unnecessary exposure.
