Analytics Documentation Generator
Auto-generate data dictionaries, lineage maps, and transformation docs from your analytics stack
What You Can Do
This skill automatically documents your entire analytics infrastructure by analyzing data sources, transformations, and outputs. You'll generate production-ready data dictionaries with field definitions, lineage maps showing data flow across systems, and transformation documentation that explains logic and dependencies. Save weeks of manual documentation work while keeping your analytics stack discoverable as it evolves.
Features
automatically catalog all tables, fields, data types, and business definitions from your warehouse
trace data flow from source systems through transformations to final analytics outputs
auto-generate docs explaining ETL logic, filters, aggregations, and dependencies
capture field descriptions, constraints, quality rules, and ownership
identify downstream dependencies when source schemas or transformations change
generate version-control-friendly documentation that lives alongside your code
pre-built connectors for Snowflake, BigQuery, Redshift, dbt, and Fivetran
automatically organize and cross-reference business term definitions across your stack
Example Output
Example Data Dictionary Entry
Table: customers_fact
Owner: Analytics Team
