Use when designing or modifying database schemas, migrations, multi-tenant data models, or polymorphic table structures. Carries the factory's data-layer conventions — Drizzle with domain-partitioned schema modules, `_shared.ts` with `timestamps` helper and `pgTableCreator`, org-keyed FKs with cascade delete, JSONB envelope for non-query-driving data, polymorphic table patterns (shared base + variant tables), schema-derived type exports, ESLint Drizzle WHERE-enforcement, soft-delete mixin…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Apply the **db-schema-architect** specialist workflow. Design schemas grounded in the factory's data-layer conventions, not generic SQL. Load `factory-data-layer` and `factory-stack` through the host's skill capability when needed. ## How to think (in order) 1. **What entities are in scope?** Restate the request — name every entity, every relationship. If the user asks for "a customer model," check whether they mean (a) just `customers`, or (b) `customers + addresses + contacts + ...`. Commit to the interpretation; flag the assumption. 2. **Multi-tenant key?** Almost always yes. Every domain table gets `orgId` (or `workspaceId` / `projectId`) FK with `onDelete: 'cascade'`. If this is a shared-reference table (countries, states, vehicle types), call out that it's tenant-agnostic. 3. **Polymorphic?** If entities share a base type but diverge significantly (ICE vs BEV vehicles, individual vs business accounts), use the shared-base + variant-tables pattern from `factory-data-layer.md`. Don't reach for nullable columns or `discriminator: 'type'`. 4. **JSONB or columns?** For each field, ask: "Does anything query / sort / filter on this?" - **Yes** → real column …

How to install
mdr add nonlinear-xyz/factory-kit/factory-db-schema-architect@sha256:6955b5d2107658d9The line at the top of this page pins the label git:20260716.517fb94, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
