Generate and apply database migration scripts. Use when changing a database schema.
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
# Database Migrate Generate and apply database migration scripts from schema changes. ## When to Use This Skill Use when the user modifies database models and needs to create a migration, or when applying pending migrations to an environment. ## Implementation Steps ### Step 1: Detect Migration Tool Check the project for migration tooling: 1. `alembic.ini` → Alembic (Python / SQLAlchemy) 2. `knexfile.js` → Knex (Node.js) 3. `dbconfig.yml` → Goose (Go) ### Step 2: Generate Migration Create a new migration file from the current model diff: - **Alembic**: `alembic revision --autogenerate -m "$DESCRIPTION"` - **Knex**: `npx knex migrate:make $DESCRIPTION` - **Goose**: `goose create $DESCRIPTION sql` ### Step 3: Review the Migration Display the generated SQL and ask the user to confirm: - Check for destructive operations (DROP TABLE, DROP COLUMN) - Verify index additions won't lock large tables - Confirm data backfill steps are idempotent ### Step 4: Apply Run the migration against the target database: - **Alembic**: `alembic upgrade head` - **Knex**: `npx knex migrate:latest` - **Goose**: `goose up` Report the migration version and any errors.

How to install
mdr add stbenjam/skillsaw/database-migrate@sha256:2832f2da6698df9bThe line at the top of this page pins the label v0.8, 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.
