This generates a markdown file that maps out your entire data warehouse structure so you don't have to keep querying it to remember what tables exist. It crawls databases, schemas, tables, and columns, then enriches everything with context from dbt models and other code in your repo. The output lives in .astro/warehouse.md, which you can version control and share with your team. It's part of Astronomer's analyzing-data workflow, so you'll need to cd into that directory to actually run it. Honestly most useful if you're working with a sprawling warehouse and tired of asking "wait, which table has the user events again?"
