To find maintainability issues in legacy code without altering behavior, analyze the codebase against a structured checklist covering dead code, duplicate logic, magic strings, and complex structures. This identifies readability and structural flaws while documenting actionable refactoring steps to ensure long-term quality.

The best way to detect dead code and obsolete feature flags during a refactor is to audit the codebase for stale branches, compatibility-only shim layers, and flags that are always on or off. This enables safe removal of redundant logic and reduces drift across modules.

Yes, you can audit naming quality and single responsibility in modules with patchy documentation by applying a maintainability review checklist. This enforces naming accuracy and verifies that functions and classes have a single, clear responsibility, detailing actionable improvement steps for better long-term quality.

To check dependency direction and visibility for coding standards compliance, review module dependencies to identify inappropriate coupling and unnecessary exposure. This enforces uniform error handling consistency and ensures structural quality without introducing functional bugs.

The limitations of static analysis for maintaining functionally correct code involve focusing primarily on readability, structure, and long-term quality rather than runtime execution. It identifies hard-coded values and duplicate logic but requires manual execution of suggested refactoring steps to achieve actual improvements.
