database-migration

Quick Review

Strong database migration skill with comprehensive ORM coverage (Sequelize, TypeORM, Prisma) and practical zero-downtime strategies. The description clearly indicates when to use this skill, and the content provides detailed, production-ready code examples covering schema transformations, rollbacks, and cross-database migrations. Structure is good with logical sections and clear examples. Novelty is moderate—while migrations are complex and error-prone, many modern ORMs provide CLI tools for basic migrations. The skill's main value is in complex scenarios (zero-downtime, data transformations, rollback strategies) where it reduces significant risk and tokens. Minor weaknesses: some referenced files in Resources section would benefit the skill if present, and the skill could be slightly more concise in places.
