Claude Plugin Library

A collection of Claude Code plugins for everyday development workflows. Each plugin is self-contained with commands, skills, and hooks that extend Claude Code for a specific domain.

Plugins

Plugin	Description
general	Research, repo exploration, docs, code review, security review, and git workflow
backend	LSP server configuration and linter templates

Installation

Native install (recommended)

First add this repository as a Claude Code marketplace, then install the plugins you want:

# Add this repo as a marketplace (one-time)
/plugin marketplace add https://github.com/bobmaertz/prompt-library

# Install plugins
claude plugin install general
claude plugin install backend

# Or install to project scope to share with your team
claude plugin install general --scope project

Uninstall with claude plugin uninstall <name>.

Symlink install (for contributors)

If you want edits to sync back to the repository automatically, clone it and use the install script instead. This symlinks each plugin directory into the Claude Code plugin cache rather than copying it.

git clone https://github.com/bobmaertz/prompt-library.git ~/.claude-plugins
cd ~/.claude-plugins
./scripts/install.sh

What	Where
Plugin symlinks	~/.claude/plugins/cache/<plugin-name>
Settings entry	~/.claude/settings.json → enabledPlugins

# Uninstall
./scripts/uninstall.sh

# Override the default ~/.claude path
CLAUDE_DIR=/custom/path ./scripts/install.sh

Testing a single plugin without installing

claude --plugin-dir ./plugins/general

Plugin Structure

Every plugin follows this layout:

<plugin-name>/
├── .claude-plugin/
│   └── plugin.json       # Required: name, version, description, author
├── commands/             # Slash commands (/command-name.md)
├── skills/               # Invokable skills
│   └── <skill-name>/
│       └── SKILL.md
├── hooks/
│   └── hooks.json        # Event hooks (PreToolUse, TaskCompleted, etc.)
└── README.md

Developing a New Plugin

1. Create a directory under plugins/<plugin-name>/
2. Add .claude-plugin/plugin.json:

   {
     "name": "my-plugin",
     "description": "What this plugin does",
     "version": "1.0.0",
     "author": { "name": "your-name" },
     "license": "MIT"
   }
   

3. Add commands/, skills/, and/or hooks/ as needed
4. Write a README.md describing commands and usage
5. Run ./scripts/install.sh to pick up the new plugin

Syncing Across Machines (symlink install)

Because the cache entries are symlinks, edits made through Claude Code write back to this repository. To sync across machines:

# Push from one machine
git add -A && git commit -m "Update plugins" && git push

# Pull on another machine
git pull
./scripts/install.sh   # only needed when adding new plugins
