Why does it flag map[:key] usage?

The skill encourages 'assertive map access' (map.key) for required keys to ensure the application fails fast with clear errors instead of propagating nil values silently.

How does this skill help with Elixir security?

It detects dangerous patterns like uncontrolled dynamic atom creation which can lead to memory exhaustion and Denial of Service (DoS) attacks on the Erlang VM.

Can it refactor complex error handling?

Yes, it specifically identifies bloated 'else' blocks in 'with' statements and suggests normalizing return types in private functions for better clarity.

What is Namespace Trespassing in Elixir?

Namespace Trespassing occurs when a library defines modules outside its own namespace, risking conflicts. This skill identifies these cases and suggests proper prefixing.

보안 및 테스팅

Identifies and refactors common Elixir code smells and design anti-patterns into idiomatic, performant code.

소개

This skill empowers Claude to act as an expert Elixir mentor by detecting non-idiomatic patterns and providing production-grade refactoring suggestions. It targets specific issues common in Elixir development, such as complex error handling in 'with' blocks, dangerous dynamic atom creation, and 'Namespace Trespassing'. By applying these best practices, developers can improve the maintainability, security, and performance of their Elixir applications while ensuring they leverage the full power of the Erlang VM.
