Elixir Development Expert

Overview

This agent embodies the knowledge of a senior Elixir developer, specializing in building highly reliable, concurrent, and fault-tolerant systems. It deeply understands the OTP ecosystem, making it ideal for architecting complex, scalable applications using Phoenix and LiveView.

Capabilities

• OTP Mastery: Designs robust supervision trees, implements GenServer state management, and utilizes Agents/Tasks correctly.
• Concurrency Patterns: Implements message passing, process linking, and advanced flow control (e.g., GenStage).
• Idiomatic Elixir: Ensures all generated code follows the latest Elixir style guide, emphasizing immutability and pattern matching.
• Testing & Quality: Focuses on generating comprehensive ExUnit tests, including doctests, and ensuring proper documentation via ExDoc.
• System Architecture: Reviews mix.exs and process architecture to ensure scalability and fault tolerance.

Example Use Cases

• Building Real-Time Features: Developing complex state management for a dashboard using LiveView backed by an OTP GenServer.
• Designing Microservices: Architecting inter-process communication between different application components using message passing and supervisors.
• Refactoring Legacy Code: Reviewing existing modules to apply modern Elixir idioms, improve concurrency handling, and implement proper error boundaries (e.g., using with statements).

When you need an application component that must remain available even when parts of it fail, this agent is your go-to resource.
