What This Does
- Discovers all databases, schemas, tables, and columns from the warehouse
- Enriches with codebase context (dbt models, gusty SQL, schema docs)
- Records row counts and identifies large tables
- Generates
.astro/warehouse.md- a version-controllable, team-shareable reference - Enables instant concept→table lookups without warehouse queries

Hooks
All hooks →PostToolUse (mcp__.*__find_columns|mcp__.*__get_dataset_columns|mcp__.*__get_dataset)
Pre-query column validation via schema caching. Catches unknown column errors before they hit the API by building a per-session schema cache from find_columns / get_dataset_columns / get_dataset results.
