Does it include testing best practices?

Absolutely. It provides guidance on keeping tests asynchronous, using Mox for allowances, and managing file system operations with ExUnit's tmp_dir.

How does this skill help with GenServers?

It enforces 'The Iron Law,' ensuring you only create processes for mutable state, concurrency, or fault isolation, preventing common over-engineering bottlenecks.

When should I trigger this skill?

Use it whenever you are implementing new features, refactoring modules, deciding on concurrency models, or structuring complex data types in Elixir.

Can this help me move from Java or Ruby to Elixir?

Yes, it specifically addresses common OOP misconceptions and provides paradigm-shifting insights to help you transition from class hierarchies to data-driven functional design.

API Development

Master the Elixir paradigm by applying idiomatic patterns, functional data modeling, and process-aware architecture.

About

This skill equips Claude with deep insights into the Elixir ecosystem, moving beyond syntax to enforce idiomatic functional programming patterns. It helps developers navigate the transition from Object-Oriented Programming (OOP) to Elixir's actor model by emphasizing pure functions, pattern matching, and the strategic use of processes. Whether you are refactoring legacy modules, designing concurrent systems with GenServers, or setting up async-safe test suites, this skill ensures your code is performant, maintainable, and aligned with the core philosophy of the Erlang runtime.

Key Features

Optimizes control flow using pattern matching, guards, and the 'with' statement
Implements async-safe testing strategies and automated temp directory management
Enforces 'The Iron Law' to prevent unnecessary and costly process creation
76 GitHub stars
Provides specific patterns for polymorphism using Behaviors and Protocols over classes
Guides the decoupling of behavior, state, and mutability for cleaner architecture

Use Cases

Optimizing data modeling through structs, recursion, and pattern matching
Architecting fault-tolerant systems using 'Let It Heal' supervision principles
Refactoring OOP-heavy codebases into idiomatic functional Elixir modules
