The Problem

Database migrations are the highest-risk moments in a software lifecycle. A simple ALTER TABLE can lock production databases, cause significant downtime, or lead to irreversible data loss. Most developers rely on default ORM behaviors which are often unsafe for high-traffic environments or large datasets.

What it Does

Migration Safety Pro equips your AI agent with a production-grade blueprint for managing database schema changes across 9+ frameworks. It moves beyond simple SQL generation by implementing industry-standard safety protocols like the Expand-Contract pattern, Ghost Tables, and Batch Backfilling.

Supported Frameworks & Tools

• Node.js: Prisma, TypeORM, Sequelize, Knex.js
• Python: Alembic (SQLAlchemy), Django Migrations
• Ruby & Go: Rails Active Record, golang-migrate
• Enterprise: Liquibase
• Databases: PostgreSQL, MySQL, MariaDB, SQLite, SQL Server

Why Use This Skill?

Instead of just getting a generic migration script, your agent will proactively identify risks like table locks on tables with >1M rows, suggest non-blocking index creation (e.g., CONCURRENTLY in Postgres), and provide mandatory rollback scripts. It ensures every change is backward-compatible, enabling true zero-downtime deployments.

Output Style

Expect structured migration plans including: a safety risk assessment, a multi-step execution strategy (Expand phase vs. Contract phase), framework-specific safe code snippets, and a concrete rollback procedure.
