--- name: multi-source-data-cleaner description: | EN: Production-grade data cleaning across heterogeneous sources (CSV/Excel/JSON/Parquet/SQL dumps/log files). Profiles schemas, detects encoding/delimiter, normalizes types, handles missing values, deduplicates fuzzy records, reconciles schema across sources, and outputs a clean unified dataset plus a full data-quality report.

cleaning is non-destructive. 5. **Dedup human-in-the-loop** — fuzzy merges above threshold but below 0.95 confidence flagged for review, not auto-committed. 6. **No external network calls** — all processing local; no data leaves the workspace. > 不静默丢数据，所有删除/合并/填充均记录到 audit/；填充值带标志列防止假冒原值；隐私字段默认脱敏；原始文件不修改；模糊去重低置信度合并强制人工复核；不向外部上传任何数据。 --- ## 🚀 Usage Examples · 使用示例 ### Example 1: Clean a single messy CSV ```bash python3 scripts/run_pipeline.py \ --input sales_q1.csv \ --output-dir ./cleaned_q1/ \ --pii-policy mask ``` ### Example 2: Merge 3 source CSVs into unified customer table ```bash python3 scripts/run_pipeline.py \ --input ./customer_sources/ \ --output-dir ./unified_customers/ \ --dedup-keys name,phone \ --priority-source crm_export.csv ``` ### Example 3: Schema reconcile with manual mapping override ```bash python3 scripts/run_pipeline.py \ --input ./multi_team_data/ \ --mapping mapping.yaml \ --output-dir ./unified/ ``` `mapping.yaml`: ```yaml target_schema: customer_id: { aliases: [客户ID, cust_id, ClientID, 编号] } phone: { aliases: [手机, 联系电话, Mobile, tel] } signup_date: { aliases: [注册日期, 开户日期, CreatedAt], type: date } ``` ### Example 4: Quality scan only (read-only audit) ```bash python3 scripts/profile.py --input ./suspicious_dataset/ --out dq_audit.md --read-only ``` --- ## 🧪 Testing · 测试 ```bash cd tests && python3 -m pytest -v ``` Fixtures include: - Encoding test set (UTF-8 BOM, GBK, BIG5, Latin1) - 12 date format variants - Schema-drift simulation across 5 source files - Synthetic dedup dataset (10k records with controlled duplication) - PII regression suite --- ## 📚 References · 参考资料 - DAMA-DMBOK Data Quality dimensions - Fellegi-Sunter probabilistic record linkage - Jaro-Winkler distance for fuzzy match - `pandas`, `pyarrow`, `recordlinkage` library docs ## 🏷️ Tags · 标签 `data` `ETL` `data-cleaning` `dedup` `schema-reconcile` `data-quality` `数据清洗` `多源整合` `去重` `数据质量`

For the initial public release we keep only the schema / placeholder files
here so the bundle stays small and reviewable. Full reference tables (ICD-10
master, drug aliases, LOINC mapping, industry medians, curriculum codes,
symbol libraries, etc.) can be added incrementally via subsequent releases
without breaking the published API.

Add your own data by dropping CSV/JSON files into this directory and
pointing the relevant environment variable in `SKILL.md` to override the
bundled defaults.
