How to Install the Everything Claude Code Plugin: 2 Methods Explained

The Everything Claude Code plugin can be installed via the Claude Code marketplace (recommended) or manually by copying files to your ~/.claude configuration directory.

Everything Claude Code is a Claude Code plugin that bundles agents, skills, hooks, commands, and rules into a battle-tested workflow. This open-source repository from WorldFlowAI provides a complete productivity system for Claude Code users who want structured, opinionated development practices.

Method 1: Marketplace Installation (Recommended)

The fastest way to install the Everything Claude Code plugin uses Claude Code's built-in /plugin commands. This method automatically registers all components through the plugin manifest at .claude-plugin/plugin.json.

Run these commands in your Claude Code session:

# Add the repository as a marketplace source (one-time setup)

/plugin marketplace add affaan-m/everything-claude-code

# Install the plugin and all its components

/plugin install everything-claude-code@everything-claude-code

The marketplace installation handles:

• Agents — Sub-agents like code-reviewer.md and tdd-guide.md
• Commands — Slash commands including /tdd and /plan
• Rules — Always-follow guidelines for security, style, and testing
• Skills — Workflow definitions and domain knowledge
• Hooks — Automation triggers for memory persistence and other features

Method 2: Manual Installation

For offline setups or custom configurations, copy the plugin files directly into your Claude Code configuration. This approach is documented in the README at lines 11-32.

Clone and install manually:

# Clone the repository

git clone https://github.com/affaan-m/everything-claude-code.git
cd everything-claude-code

# Copy core plugin components

cp agents/*.md   ~/.claude/agents/
cp rules/*.md    ~/.claude/rules/
cp commands/*.md ~/.claude/commands/
cp -r skills/*   ~/.claude/skills/

# Merge hooks configuration into your settings

jq '.hooks += (import "hooks/hooks.json")' ~/.claude/settings.json > tmp && mv tmp ~/.claude/settings.json

The manual method requires the jq utility for JSON manipulation. Install it via your system package manager if needed.

Optional: Configure Your Package Manager

The Everything Claude Code plugin includes a cross-platform utility at scripts/setup-package-manager.js that detects and configures your preferred Node.js package manager.

# Detect current package manager setting

node scripts/setup-package-manager.js --detect

# Set a global default (npm, pnpm, yarn, or bun)

node scripts/setup-package-manager.js --global pnpm

This configuration affects how the plugin's commands interact with Node.js projects.

Verify Your Installation

Confirm the Everything Claude Code plugin is active:

# List all installed plugin commands

/plugin list

# Test a core command

/tdd

Successful execution without errors indicates proper installation. The /tdd command triggers the test-driven development workflow defined in commands/tdd.md.

Key Plugin Files

Understanding these files helps with troubleshooting and customization:

• .claude-plugin/plugin.json — Plugin manifest declaring agent, skill, command, and rule locations
• hooks/hooks.json — Central hooks definition enabling automation features
• agents/ — Markdown sub-agent definitions (e.g., code-reviewer.md)
• commands/ — Slash-command implementations (e.g., tdd.md, plan.md)
• rules/ — Persistent guidelines for Claude Code behavior
• skills/ — Reusable workflow and domain knowledge modules

Summary

• Marketplace install — Use /plugin marketplace add and /plugin install for automatic setup
• Manual install — Copy files from agents/, rules/, commands/, and skills/ to ~/.claude/
• Package manager — Run scripts/setup-package-manager.js to configure npm/pnpm/yarn/bun preferences
• Verification — Execute /plugin list and /tdd to confirm successful installation

Frequently Asked Questions

What is the Everything Claude Code plugin?

The Everything Claude Code plugin is a Claude Code extension that bundles pre-configured agents, commands, rules, skills, and hooks into a unified productivity system. It implements battle-tested workflows documented in the WorldFlowAI/everything-claude-code repository, giving users structured approaches to code review, test-driven development, and project planning without manual configuration.

Can I use the plugin offline?

Yes. The manual installation method works entirely offline. Clone the repository once, then copy the required files to your ~/.claude/ directory without needing marketplace access. The plugin manifest at .claude-plugin/plugin.json and all component files are self-contained in the repository.

How do I uninstall or update the plugin?

For marketplace installations, use /plugin uninstall everything-claude-code to remove the plugin, then /plugin install everything-claude-code@everything-claude-code to reinstall the latest version. For manual installations, delete the corresponding files from ~/.claude/agents/, ~/.claude/rules/, ~/.claude/commands/, and ~/.claude/skills/, then re-copy from a fresh clone.

What Claude Code version is required?

The plugin uses standard Claude Code plugin APIs introduced in early 2025. Ensure your Claude Code installation supports the /plugin command family. The repository's README.md at lines 75-88 and plugins/README.md at lines 31-40 document any version-specific requirements.
