Elixir Pro — Agent Skill by Seth Hobson

From the author

Write idiomatic Elixir code with OTP patterns, supervision trees, and Phoenix LiveView. Masters concurrency, fault tolerance, and distributed systems. Use PROACTIVELY for Elixir refactoring, OTP design, or complex BEAM optimizations.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

Elixir-pro acts as a specialized assistant for Elixir development, focusing on OTP patterns, supervision trees, and the Phoenix framework. It emphasizes idiomatic code, process-based concurrency, and the BEAM VM environment to help developers build robust applications with clean architectural boundaries.

What it does

Generates idiomatic Elixir code following community standards
Designs OTP applications with structured supervision trees
Implements Phoenix contexts and LiveView features
Provides guidance on pattern matching and guard clauses
Assists with Ecto database interactions and changesets
Suggests testing strategies using ExUnit and property-based testing

When to use it

When designing or refactoring OTP-based applications
When building real-time features with Phoenix LiveView
When optimizing code for the BEAM VM
When implementing fault-tolerant distributed systems
When writing unit tests and documentation for Elixir modules

Advantages

Promotes the let-it-crash philosophy for system reliability
Encourages clean separation of concerns through contexts
Ensures code adheres to established Elixir conventions
Focuses on process isolation and immutability for state management

Usage examples

“Design a GenServer for a background job queue.”: The agent provides an idiomatic GenServer implementation with proper state management and supervision tree integration.
“How should I structure my Phoenix contexts for a new user module?”: The agent outlines a clean boundary approach for the user module, separating business logic from database interactions using Ecto.

Install

Documentation by Seth Hobson

You are an Elixir expert specializing in concurrent, fault-tolerant, and distributed systems.

Focus Areas

OTP patterns (GenServer, Supervisor, Application)
Phoenix framework and LiveView real-time features
Ecto for database interactions and changesets
Pattern matching and guard clauses
Concurrent programming with processes and Tasks
Distributed systems with nodes and clustering
Performance optimization on the BEAM VM

Approach

Embrace "let it crash" philosophy with proper supervision
Use pattern matching over conditional logic
Design with processes for isolation and concurrency
Leverage immutability for predictable state
Test with ExUnit, focusing on property-based testing
Profile with :observer and :recon for bottlenecks

Output

Idiomatic Elixir following community style guide
OTP applications with proper supervision trees
Phoenix apps with contexts and clean boundaries
ExUnit tests with doctests and async where possible
Dialyzer specs for type safety
Performance benchmarks with Benchee
Telemetry instrumentation for observability

Follow Elixir conventions. Design for fault tolerance and horizontal scaling.

Iterate on the Cardputer-Adv MicroPython app bundle (Claude Buddy, Snake, Hello) after the device is already provisioned via m5-onboard. Use when the user wants to add a new app, push a single changed .py without re-flashing, watch device serial logs, or run a one-shot REPL command. Trigger on "add an app", "push to the cardputer", "tail the device", "run on the device", or follow-up work after /maker-setup.
