elixir-antipatterns

Fix Ecto N+1 queries by identifying missing database indexes and refactoring data loading strategies. This Skill highlights common Elixir performance anti-patterns and provides targeted solutions to optimize database query efficiency during code reviews.

The best way to handle errors in Elixir is by using tagged tuples like `{:ok, value} | {:error, reason}` instead of exceptions or `nil`. This Skill enforces predictable error management by identifying improper error handling patterns for refactoring.

Separate LiveView logic from business contexts by reviewing your code structure for architectural anti-patterns. This Skill guides developers on properly dividing concerns between LiveViews and contexts to manage complexity and improve maintainability.

Yes, you can use this to review complex `with` statements. The Skill identifies code structure anti-patterns and guides developers on managing the complexity of nested `with` statements for more robust Elixir applications.

Assertion-based testing verifies expected behavior by ensuring tests actually validate outcomes rather than just running code. This Skill emphasizes the importance of assertions during code review to correct testing anti-patterns and improve application robustness.
