Can it help fix performance issues like N+1 queries?

Yes, it offers specific advice on when to use separate preloads versus join preloads to optimize memory usage and query speed based on association types.

Does it support multi-tenant Elixir applications?

Absolutely, it includes advanced guidance on composite foreign keys, CTE prefixing in multi-tenant apps, and specific pgbouncer configurations.

How does Ecto Thinking help with Domain-Driven Design?

It provides specific patterns for decoupling contexts by using ID references instead of direct associations and mapping business domains to specific schemas rather than just database tables.

Is this skill only for database migrations?

No, it covers the entire Ecto lifecycle, including schema design, changesets, query composition, transactions, and how different contexts should communicate.

Guides Elixir developers through Ecto data layer design, domain-driven architecture, and database performance optimizations.

Ecto Thinking is a specialized skill for Claude Code designed to help Elixir developers architect robust data layers using the Ecto library. It moves beyond simple ORM patterns to implement Domain-Driven Design (DDD) principles, such as bounded contexts, decoupled schema associations via IDs, and operation-specific changesets. By providing expert-level guidance on multi-tenancy, performance trade-offs between preloads and joins, and critical 'gotchas' involving PostgreSQL and Ecto internals, this skill ensures your Elixir backend is scalable, maintainable, and free from common pitfalls.
