ref / source — always use {{ ref('model') }} and {{ source() }}; never hard-code raw table names in marts.
Tests on every model — at minimum unique + not_null on primary keys in marts.
Staging → intermediate → mart — match existing layer naming in the project.
Materialization — follow project defaults; do not switch to table/incremental without cost note.
Cross-ref official skills — dbt Labs publishes marketplace skills; this harness skill adds guardrails + routing, not a duplicate corpus.
