claude-plugin-hello

A minimal Claude Code plugin example, distributed directly from GitHub — no npm publish, no registry auth.

Structure

├── .claude-plugin/
│   └── plugin.json          # Plugin manifest (name, version, description)
├── skills/
│   └── hello-world/
│       └── SKILL.md         # Skill definition (frontmatter + instructions)
├── marketplace.json          # Marketplace registry — points to this GitHub repo
└── package.json              # npm package metadata (no publishConfig needed)

How it works

1. Plugin manifest — .claude-plugin/plugin.json identifies the plugin to Claude Code.
2. Skill discovery — Claude Code auto-discovers any skills/*/SKILL.md in the installed package.
3. Distribution — marketplace.json uses "package": "github:moshfeu/claude-plugin-hello", which tells npm to install directly from this repo. No registry, no publish step needed.

Install via marketplace

# Add this marketplace (raw GitHub URL of marketplace.json)
claude marketplace add https://raw.githubusercontent.com/moshfeu/claude-plugin-hello/main/marketplace.json

# Install the plugin
claude marketplace install claude-plugin-hello

No tokens or authentication required — public GitHub repo = anyone can install.

Publish a new version

Just push to GitHub. To pin to a specific commit or tag:

"package": "github:moshfeu/claude-plugin-hello#v1.1.0"

Use the skill

After installing, type /hello <your name> in Claude Code.
