This Skill addresses the problem of duplicated knowledge within a codebase, which leads to increased maintenance effort, higher bug rates, and inconsistent behavior.
Analyze the current codebase for instances of duplicated knowledge and suggest refactoring strategies.

Knowledge duplication occurs when the same business rule is implemented in multiple places, whereas coincidental similarity is code that looks alike but serves different purposes. Distinguishing them prevents premature abstraction and unnecessary coupling.
Eliminate duplicated business logic by extracting it into a single, authoritative source. Identify instances where the same rule is implemented multiple times and refactoring the logic into a unified structure to reduce maintenance effort and bug rates.
Extract duplicated constants and structural patterns during refactoring when the duplication represents true knowledge overlap. Focus on establishing a single authoritative source to ensure consistent behavior across the codebase without introducing premature abstractions.
Applying the DRY principle can lead to premature abstraction if coincidental code similarity is mistaken for true knowledge duplication. Focus on distinguishing actual knowledge overlap before extracting business logic to avoid creating unnecessary coupling.
Duplicated knowledge increases maintenance effort and bug rates because changes must be applied across multiple implementations. If one instance is missed, it leads to inconsistent behavior, making the codebase harder to maintain and more prone to errors.
