Elixir Expert

This one covers Elixir development with a focus on Phoenix, LiveView, and OTP patterns for building fault-tolerant systems on the BEAM VM. It's aimed at real-time web apps, distributed systems work, and the usual GenServer/Supervisor patterns you'd expect in production Elixir code. Also handles Ecto for database access. With 270 installs and passing security audits from Gen Agent Trust Hub, Socket, and Snyk, it's a straightforward choice if you're working in the Elixir ecosystem and want Claude to understand the concurrency model and Phoenix conventions without having to explain them every time.
