The Database Migration Helper is a specialized skill designed to guide developers through the lifecycle of database schema evolution. It provides structured patterns for creating, testing, and deploying migrations while emphasizing safety through mandatory rollback functions and idempotent operations. Supporting a wide array of tools including Knex.js, Prisma, TypeORM, and Sequelize, this skill is indispensable for backend engineers performing complex data transformations, modifying large production tables without downtime, or standardizing migration workflows across a team.
