Validate Vellum Assistant database and workspace migrations. Use when adding, editing, reviewing, or testing migrations, release-note migrations, persisted schemas, workspace file formats, or data backfills.
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
# Vellum Migration Checklist ## When A Migration Is Required Use a migration for shipped interfaces and persisted data: - DB schema changes, indexes, backfills, or persisted row shape changes. - Workspace file renames, moves, format changes, or namespace changes. - Stored config or data that existing installs must keep reading. Do not delete migration files. Migrations are append-only, even when their logic becomes obsolete. ## DB Migrations For DB migrations: 1. Add a new file under `assistant/src/persistence/migrations/`. 2. Make it idempotent and safe to retry after interruption. 3. Register it in the `migrationSteps` array in `assistant/src/persistence/steps.ts`. 4. Update schema modules if the runtime schema changed. 5. Add or update a focused `db-*migration*.test.ts` test. Check for ordering drift and never reorder existing migrations. ## Workspace Migrations For workspace migrations: 1. Add a new numbered file under `assistant/src/workspace/migrations/`. 2. Append it to `WORKSPACE_MIGRATIONS` in `assistant/src/workspace/migrations/registry.ts`. 3. Make the migration idempotent. 4. Add or update a focused `workspace-migration-*.test.ts` test. …

How to install
mdr add vellum-ai/vellum-assistant/vellum-migration-checklist@sha256:7c94fc727857ab98The line at the top of this page pins the label git:20260702.d65ff55, 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.
