Overview

Advanced Erlang programming skills for concurrent and distributed systems

Skills

This plugin provides the following skills:

  • Erlang Concurrency
  • Erlang Distribution
  • Erlang Otp Behaviors

Usage

Once enabled, Claude will automatically apply these skills when working with relevant code. The plugin provides context and expertise that Claude uses to:

  • Write idiomatic code following best practices
  • Suggest appropriate patterns and architectures
  • Catch common mistakes and anti-patterns
  • Provide framework-specific guidance

Installation

Install with npx (no installation required):

han plugin install jutsu-erlang

Skills

📖

Erlang Concurrency

Use when erlang's concurrency model including lightweight processes, message passing, process links and monitors, error handling patterns, selective receive, and building massively concurrent systems on the BEAM VM.

📖

Erlang Distribution

Use when erlang distributed systems including node connectivity, distributed processes, global name registration, distributed supervision, network partitions, and building fault-tolerant multi-node applications on the BEAM VM.

📖

Erlang OTP Behaviors

Use when oTP behaviors including gen_server for stateful processes, gen_statem for state machines, supervisors for fault tolerance, gen_event for event handling, and building robust, production-ready Erlang applications with proven patterns.

Hooks

⚠

Token Usage Notice

Hooks run automatically during Claude Code sessions and their output is sent to the model for processing. This may increase token usage and associated costs. Consider disabling hooks you don't need via han-config.yml.

🛑

Stop

Runs when the main Claude Code agent has finished responding. Can verify task completion, check quality gates, or ensure documentation requirements are met before the session ends.

🛑

SubagentStop

Runs when a Claude Code subagent (Task tool call) has finished responding. Can validate subagent outputs, enforce quality standards, or trigger additional workflows after delegated tasks complete.
