OpenPackage

OpenPackage turns your AI coding setups into reusable modules that anyone can instantly install to any platform, any codebase, ensuring consistent workflows across projects and teams.

Why OpenPackage?

Modern AI coding tools are powerful, but lack organization, reusability, and efficiency.

• Rules, commands, subagents, and skills scattered across multiple projects.
• Familiar workflows rebuilt for each project, incompatible between AI coding platforms.
• Specs across individuals and codebases, diverging, unversioned, and incohesive.

OpenPackage takes care of cross-platform conversions, config composition, and portability, freeing you to build more, faster.

• Install & sync pre-built workflows to speed up coding. No more reinventing the wheel.
• Reuse rules, slash commands, and skills across multiple codebases and platforms.
• Share and compose packages together to create powerful workflows that continuously evolve.

Use cases

• Install Claude Code Plugins to any coding platform
• Sync specs, rules, commands, agents, skills, and MCPs across platforms
• Reuse files and configs across multiple codebases
• Modular management of configs and specs

How it works

At its core, OpenPackage is a lightweight CLI tool for creating versioned, AI coding platform agnostic packages, each contaning sets of coding config files and specs for simplified installs, uninstalls, and distribution.

It's basically Claude Code Plugins, but universal, more powerful, and open source.

1. Declare a package
2. Add rules, commands, subagents, skills, mcp configs, specs, docs etc.
3. Install and sync to multiple codebases

Quick start

Install

npm

npm install -g opkg 

Install packages

opkg install <package>

Installs all files from a package into the codebase at cwd, formatted and converted to per platform conventions and into their respective dirs.

The install command supports various package sources:

opkg install essentials               # Local/remote registry
opkg install ../packages/essentials/  # Local path

# GitHub package repo
opkg install git:https://github.com/enulus/awesome-openpackage.git    

# GitHub Claude Code Plugins marketplace          
opkg install github:anthropics/claude-code

Use the --global (or -g) option to install files to user scope:

# Installs to home dir, ex: ~/.cursor/, ~/.opencode/
opkg install github:anthropics/claude-code -g

Show installed packages and files

opkg status             # Lists packages installed to workspace at cwd
opkg status <package>   # Lists installed files for specified package

Use the status command to show an overview of packages and files installed.

Uninstall packages

opkg uninstall <package>

Removes all files for a package from the codebase at cwd.

Compose a package

opkg new <package>

Then manually add/update/remove files to and from the package following this structure:

<package>
│   
│   # Package files
├── openpackage.yml       # The OpenPackage manifest, required
├── README.md             # LICENSE.md, CONTRIBUTING.md, etc.
│   
│   # Content files
├── rules/                # Rule files
├── commands/             # Command files (slash commands)
├── agents/               # Agent files (subagents)
├── skills/               # Skill files (skills)
├── root/                 # Any other root dirs or files (Ex: specs/, docs/, tests/, etc.)
├── AGENTS.md             # Platform root file
├── mcp.jsonc             # MCP config file
│   
│   # Custom files
└── <other>               # Customizable via `platforms.jsonc` overrides/extensions

You can also use the add and remove commands to add/remove files to/from a package.

opkg add <package> .cursor/commands/clean.md    # Adds workspace file or dir to package
opkg remove <package> commands/clean.md         # Removes file or dir from package

Supported Platforms

OpenPackage performs installation and platform sync of files for supported AI coding platforms outlined by the table below.

Platform	Directory	Root file	Rules	Commands	Agents	Skills	MCP
Antigravity	.agent/		rules/	workflows/		skills/
Augment Code	.augment/		rules/	commands/
Claude Code	.claude/	CLAUDE.md	rules/	commands/	agents/	skills/	.mcp.json (root)
Codex	.codex/	AGENTS.md		prompts/		skills/	config.toml
Cursor	.cursor/	AGENTS.md	rules/	commands/	agents/	skills/	mcp.json
Factory	.factory/	AGENTS.md		commands/	droids/	skills/	mcp.json
Kilo Code	.kilocode/	AGENTS.md	rules/	workflows/		skills/	mcp.json
Kiro	.kiro/		steering/				settings/mcp.json
OpenCode	.opencode/	AGENTS.md		command/	agent/	skills/	opencode.json
Qwen Code	.qwen/	QWEN.md			agents/	skills/	settings.json
Roo	.roo/	AGENTS.md		commands/		skills/	mcp.json
Warp	.warp/	WARP.md
Windsurf	.windsurf/		rules/			skills/

The built-in platforms.jsonc defines supported platforms, but can be overridden by user configs:

• Global: ~/.openpackage/platforms.jsonc (.json)
• Workspace: <cwd>/.openpackage/platforms.jsonc (.json)

Deep-merged (local > global > built-in) for per-project customization.
