anti-duplication

To prevent code duplication, proactively search the repository for existing implementations before writing new code. This skill analyzes exact, close, and pattern matches to offer reuse options that maximize consistency and maintainability.

Finding existing patterns for reuse involves applying semantic, literal, and pattern analyses across the codebase. This process identifies matching endpoints or components and presents options to extend established patterns instead of duplicating logic.

Documenting code reuse decisions involves recording the justification for extending an existing pattern or creating a new implementation. This practice aligns new work with established anti-pattern guidelines and ensures long-term maintainability.

Yes, anti-duplication checks apply to general software engineering tasks across any codebase. The skill requires no external dependencies and proactively searches for existing services, components, and endpoints before coding begins.

Searching for existing implementations before writing new code prevents redundant logic and ensures consistent solutions. It guides decision-making by evaluating semantic and literal matches to maximize code reuse and structural consistency.
