# Data Lineage Mapper Extracts and maps data lineage from various sources to provide comprehensive data flow visibility. ## Overview This skill parses and extracts data lineage information from SQL queries, dbt projects, Airflow DAGs, and Spark jobs. It generates comprehensive lineage graphs showing data flow from source to destination, enabling impact analysis and data governance. ## Capabilities - **SQL parsing for lineage extraction** - Parse SELECT, INSERT, MERGE statements - **dbt lineage integration** - Extract lineage from manifest.json - **Airflow task lineage mapping** - Map data flows across DAG tasks - **Spark job lineage extraction** - Parse Spark SQL and DataFrame operations - **Cross-system lineage connection** - Connect lineage across different tools - **Column-level lineage tracing** - Track individual column transformations - **Impact analysis** - Downstream/upstream impact assessment - **Lineage graph generation** - Visual and machine-readable lineage - **Integration with data catalogs** - Export to DataHub, Amundsen, Alation ## Input Schema ```json { "sources": { "type": "array", "required": true, "items": { "type": { "type": "string", "enum": ["sql", "dbt", "air

What does the data-lineage-mapper skill do?
Extracts and maps data lineage from various sources including SQL, dbt, Airflow, and Spark, generating comprehensive lineage graphs for impact analysis.
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill data-lineage-mapper --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
