ol-data-platform

Drive the ol-dbt CLI (validate, impact, diff) to QA dbt-warehouse changes fast and credential-free before opening or reviewing a PR. Use this skill whenever you edit models under src/ol_dbt/ (especially dimensional, mart, or reporting models) and need to check SQL/YAML consistency, column-level downstream blast radius, or whether a migrated model still matches its predecessor — all on the local DuckDB target, no Trino/warehouse credentials required.

Stand up and drive the local DuckDB + Iceberg dbt development environment via `ol-dbt local` and `ol-dbt run`. Use this skill when you need to build or iterate on src/ol_dbt models locally against real production data (zero-copy, no warehouse writes) — e.g. to materialize an old and a new model side-by-side for `ol-dbt diff`, to iterate fast on a single changed model, or to bootstrap a fresh local warehouse. Covers setup, Glue→DuckDB view registration, incremental runs, and safe teardown.
