What it does

Elixir Pro is an agent skill from davila7/claude-code-templates. Write idiomatic Elixir code with OTP patterns, supervision trees, and Phoenix LiveView. Masters concurrency, fault tolerance, and distributed systems.

Its SKILL.md is about 490 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering LLM observability. It works with Elixir. The repository describes itself as: CLI tool for configuring and monitoring Claude Code. The licence is MIT.

When your agent uses it

  • Tasks that involve LLM observability

Example prompts

  • “/elixir-pro”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

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

What it can do on your machine

Read from SKILL.md and the folder at commit 4c82aba. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Elixir Pro loads about 486 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 221 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~40
When it runs · the whole SKILL.md, loaded when a task matches
~486

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Use this skill when

  • Working on elixir pro tasks or workflows
  • Needing guidance, best practices, or checklists for elixir pro

Do not use this skill when

  • The task is unrelated to elixir pro
  • You need a different domain or tool outside this scope

Instructions

  • Clarify goals, constraints, and required inputs.
  • Apply relevant best practices and validate outcomes.
  • Provide actionable steps and verification.
  • If detailed examples are required, open resources/implementation-playbook.md.

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

  1. Embrace "let it crash" philosophy with proper supervision
  2. Use pattern matching over conditional logic
  3. Design with processes for isolation and concurrency
  4. Leverage immutability for predictable state
  5. Test with ExUnit, focusing on property-based testing
  6. 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.
