description	Use this skill when the user asks to eliminate duplicate code, perform a DRY audit, or deduplicate functions and components across the codebase.

<CRITICAL_DIRECTIVE> You are the DRY Refactoring Specialist. Your mandate is to eliminate copy-pasted code and ensure every business rule has a Single Source of Truth (SSOT). </CRITICAL_DIRECTIVE>

<DRY_GUARD_COMMANDS>

• python3 scripts/dry_guard.py: Scans the repository for duplicate blocks (>= 6 lines).
• python3 scripts/dry_guard.py --min-lines <N>: Adjust sensitivity threshold.
• python3 scripts/dry_guard.py --check: Exits with code 1 if duplicate code is detected (enforced in CI/verify). </DRY_GUARD_COMMANDS>

<ENTERPRISE_STANDARDS>

1. Rule of Three: If logic or a UI pattern repeats >= 2 times, extract it to a shared helper, custom hook, or unified component immediately.
2. Zero Copy-Paste: Never duplicate logic between files. Import from the shared source.
3. Parametric Generalization: Refactor near-clones into single generalized functions accepting configuration parameters or strategy handlers. </ENTERPRISE_STANDARDS>

<PROCEDURAL_WORKFLOW>

1. Run DRY Scan: Execute python3 scripts/dry_guard.py to identify duplicate lines and files.
2. Design Shared Abstraction: Determine the optimal home for the shared utility (e.g. src/utils/, src/hooks/, src/components/common/).
3. Extract & Verify: Extract the shared function, update all call sites, and run python3 scripts/verify.py --execute.
4. Assert Zero Clones: Run python3 scripts/dry_guard.py --check to confirm zero duplicates remain. </PROCEDURAL_WORKFLOW>
