Projects often accumulate duplicated code blocks, creating maintenance headaches and drift. This Skill scans code across files to surface DRY violations and proposes targeted extractions to improve long-term readability and reuse.
Run /trw-dry-check [file-patterns...] to scan the repository for duplicated code patterns and generate a refactoring plan.

To detect duplicate code blocks across files, you can scan the repository to surface DRY violations and receive targeted extraction proposals. This process requires block-level comparison of 5+ consecutive lines with whitespace normalization to identify exact and near-duplicates.
The minimum requirement for duplicate code detection is 5+ consecutive lines. The analysis applies block-level comparison with whitespace normalization to accurately identify duplicated code blocks and suggest clean extractions.
Yes, you can use static analysis to find refactoring candidates during code reviews or CI checks. It summarizes total duplicated blocks found, affected files, and recommended extractions to guide code reviews and improve maintainability.
To generate a refactoring plan for consolidating common utilities, scan the codebase to surface candidates for extraction. The analysis provides a concise owner-and-signature suggestion for the extracted helper to guide implementation.
Yes, duplicate code detection works for projects of varying sizes and languages. It applies cross-file duplicate detection to identify exact and near-duplicate code blocks across the codebase regardless of the project scale.
