About this skill

The elixir-expert skill provides specialized assistance for the Elixir programming language, helping agents generate code, debug issues, and explain complex functional programming concepts within the Phoenix framework ecosystem. It acts as a dedicated domain expert to streamline development workflows for backend systems built with Erlang VM.

When to use it

  • Generating server-side logic or API endpoints using Phoenix LiveView and Ecto ORM.
  • Debugging runtime errors specific to the BEAM virtual machine or concurrency patterns in Elixir.
  • Explaining functional programming paradigms such as immutability, pattern matching, and recursion.
  • Refactoring legacy Erlang codebases into modern Elixir syntax.

Key capabilities

  • Deep knowledge of the Phoenix web framework architecture.
  • Proficiency with Ecto for database schema design and queries.
  • Expertise in OTP (Open Telecom Platform) principles for distributed systems.
  • Ability to write idiomatic, functional code adhering to Elixir best practices.

Example prompts

  • "Create a Phoenix LiveView component that fetches user data from the database using Ecto and handles real-time updates."
  • "Explain how OTP supervisors manage process hierarchies in an Elixir application and provide a concrete example."
  • "Debug this error: 'FunctionClauseError' when attempting to match on a nil value in my Elixir script."

Tips & gotchas

Ensure you provide context about your specific version of Elixir and Phoenix, as API behaviors can change between major releases. For complex concurrency issues, explicitly mention the OTP behavior or supervisor type involved to get more targeted advice.
