Overview

Advanced Nim programming skills for systems programming and metaprogramming

Skills

This plugin provides the following skills:

  • Nim C Interop
  • Nim Memory Management
  • Nim Metaprogramming

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-nim

Skills

📖

Nim C Interop

Use when nim-C interoperability including calling C from Nim, wrapping C libraries, importc/exportc pragmas, header generation, FFI patterns, and building high-performance systems code integrating Nim with existing C codebases.

📖

Nim Memory Management

Use when nim's memory management including garbage collection strategies, manual memory control, destructors, move semantics, ref/ptr types, memory safety, and optimization techniques for performance-critical systems programming.

📖

Nim Metaprogramming

Use when nim's metaprogramming including macros, templates, compile-time evaluation, AST manipulation, code generation, DSL creation, and leveraging compile-time computation for performance and abstraction in systems programming.

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.
