Then install this plugin:

han plugin install jutsu-gleam

Overview

Advanced Gleam programming skills for functional BEAM development

Skills

This plugin provides the following skills:

  • Gleam Actor Model
  • Gleam Interop
  • Gleam Type System

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-gleam

Skills

📖

Gleam Actor Model

Use when oTP actor patterns in Gleam including processes, message passing, GenServer implementations, supervisors, fault tolerance, state management, and building concurrent, fault-tolerant applications on the Erlang VM.

📖

Gleam Erlang Interop

Use when gleam-Erlang interoperability including calling Erlang code from Gleam, using Erlang libraries, external functions, working with Erlang types, NIFs, and leveraging the BEAM ecosystem from Gleam applications.

📖

Gleam Type System

Use when gleam's type system including algebraic data types, custom types, pattern matching, generic types, type inference, opaque types, exhaustive checking, and functional error handling for building type-safe Erlang VM applications.

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.
