What is Claude Skill Lord?

Claude Skill Lord is a curated plugin for Claude Code that adds 43 specialized agents, 165 production-ready skills, 114 commands, and 11 language rule sets to your development workflow. One install gives Claude deep expertise in planning, coding, testing, reviewing, debugging, and designing — across any language or framework.

Quick Start

Install globally (recommended)

npm i -g claude-skill-lord

Set up in any project

cd your-project
csl init       # copies agents, skills, commands into .claude/
claude         # start coding with Claude Skill Lord

That's it. csl init generates plugin.json and wires everything up automatically.

Alternative installs

# Per-project
npm i claude-skill-lord && npx csl init

# From source
git clone https://github.com/donganhvuphp/Claude-Skills-Lord.git
cd Claude-Skills-Lord && node scripts/sl.js init --target /path/to/your/project
