Migrate Skill

Run database/schema migrations in non-interactive mode.

Usage

/migrate up             # Run pending migrations
/migrate down           # Roll back last migration
/migrate rollback       # Same as down
/migrate status         # Show migration status
/migrate create name    # Create a new migration file

Instructions

Read claude/build.md for the actual migration commands configured for this project.

Determine action from $ARGUMENTS:

Argument	Action
up or migrate	{{MIGRATE_UP_CMD}}
down or rollback	{{MIGRATE_DOWN_CMD}}
status	{{MIGRATE_STATUS_CMD}}
create <name>	{{MIGRATE_CREATE_CMD}} <name>

⚠️ Migration Safety Rules:

• NEVER mix DDL and DML in the same migration
• Test rollback after every new migration: run up → verify → run down → run up again
• Column names: snake_case, scoped by table, no redundant prefixes
• For irreversible migrations (column drop, type change): require explicit user confirmation
• NEVER run migrations directly on production without a backup confirmation
