# Check Code Duplication Skill
This skill provides a systematic approach to finding and pruning duplicate code blocks and repeated boilerplate across Python, TypeScript, and JavaScript source files.
## Workflow
1. **Run the Duplication Spotter**:
Execute `python scripts/check_code_duplication.py` to identify duplicate code blocks:
```bash
uv run python scripts/check_code_duplication.py -m 6 -n 20
```
2. **Target High-Score Duplications**:
Focus on blocks with high duplication scores (lines $\times$ occurrences) in source modules.
3. **Prune & Deduplicate**:
- Extract repeated boilerplate or constructor patterns into shared helper functions.
- Collapse repeated dictionary/object constructions into helper functions.
- Maintain 3+ call sites requirement for new abstractions.
4. **Verify Behavior**:
Always run test suites to ensure zero functional regressions:
- Python: `uv run pytest` & `uv run mypy src`
- Node: `npm run build && npm test`
- LangChain: `uv run pytest` in `langchain`
