Review Duplication

Overview

This skill provides a structured workflow for investigating a codebase during a code review to identify duplicated logic, reinvented utilities, and missed opportunities to reuse established patterns. By executing this workflow, you ensure that new code integrates seamlessly with the existing project architecture.

Workflow: Investigating for Duplication

When reviewing code, perform the following steps before finalizing your review:

1. Extract Core Logic

Analyze the new code to identify the core algorithms, utility functions, generic data structures, or UI components being introduced. Look beyond the specific business logic to see the underlying mechanics.

2. Hypothesize Existing Locations & Trace Dependencies

Think about where this type of code would live if it already existed in the project. Provide absolute paths from the repo root to disambiguate.

• Utilities: packages/core/src/utils/, packages/cli/src/utils/
• UI Components: packages/cli/src/ui/components/, packages/cli/src/ui/
• Services: packages/core/src/services/, packages/cli/src/services/
• Configuration: packages/core/src/config/, packages/cli/src/config/
