Enforces best practices for Elixir Ecto database schemas, changesets, queries, and migrations.
Ecto Essentials is a comprehensive guidance system for Elixir and Phoenix developers working with the Ecto database library. It streamlines the creation of robust data layers by enforcing mandatory patterns like changeset-driven updates, association preloading to prevent N+1 queries, and the use of the Context pattern for clean architecture. Whether you are defining complex schemas, writing multi-step transactions, or building dynamic query compositions, this skill ensures your database logic is performant, maintainable, and follows industry-standard security practices like database-level constraints.
