How to Install All Plugins for PM Skills Marketplace: Complete Guide

Install all nine PM Skills plugins by adding the marketplace repository phuryn/pm-skills and deploying each plugin with the @pm-skills suffix, using either GUI workflows in Claude Cowork or CLI commands in Claude Code and Codex.

The PM Skills Marketplace is an open-source collection hosted in the phuryn/pm-skills repository that bundles nine specialized plugins for product management workflows. Each plugin covers a distinct domain—discovery, strategy, execution, market research, data analytics, go-to-market, marketing-growth, toolkit, and AI-shipping—defined in the central manifest at .claude-plugin/marketplace.json.

Understanding the Marketplace Structure

The repository uses a machine-readable manifest at .claude-plugin/marketplace.json to enumerate the nine available plugins. This JSON file defines plugin names, source directories, and descriptions, allowing CLI tools to resolve the @pm-skills namespace when installing individual components. The manifest ensures that when you register the marketplace, your interface recognizes all nine plugin packages as valid installation targets.

Installation Methods for All Nine Plugins

Method 1: Claude Cowork (GUI)

For users accessing Claude through the Cowork interface, the installation requires no command-line tools and automatically imports all nine plugins.

1. Open Customize → Browse plugins → Personal → +
2. Select Add marketplace from GitHub
3. Enter the repository identifier phuryn/pm-skills

The system reads the marketplace manifest and makes all nine plugins immediately available.

Method 2: Claude Code (CLI)

For terminal-based Claude Code users, first register the marketplace source, then install each plugin individually using the @pm-skills suffix.

Register the marketplace:

claude plugin marketplace add phuryn/pm-skills

Install the complete set of nine plugins:

claude plugin install pm-toolkit@pm-skills
claude plugin install pm-product-strategy@pm-skills
claude plugin install pm-product-discovery@pm-skills
claude plugin install pm-market-research@pm-skills
claude plugin install pm-data-analytics@pm-skills
claude plugin install pm-marketing-growth@pm-skills
claude plugin install pm-go-to-market@pm-skills
claude plugin install pm-execution@pm-skills
claude plugin install pm-ai-shipping@pm-skills

Method 3: Codex CLI (OpenAI)

Codex CLI uses similar marketplace registration but employs add instead of install when deploying individual plugins.

Register the marketplace:

codex plugin marketplace add phuryn/pm-skills

Install all nine plugins:

codex plugin add pm-toolkit@pm-skills
codex plugin add pm-product-strategy@pm-skills
codex plugin add pm-product-discovery@pm-skills
codex plugin add pm-market-research@pm-skills
codex plugin add pm-data-analytics@pm-skills
codex plugin add pm-marketing-growth@pm-skills
codex plugin add pm-go-to-market@pm-skills
codex plugin add pm-execution@pm-skills
codex plugin add pm-ai-shipping@pm-skills

Automated Installation Script

To streamline the process in Claude Code, use a shell loop to install all plugins after adding the marketplace:

# Add marketplace once

claude plugin marketplace add phuryn/pm-skills

# Install all nine plugins

for plugin in pm-toolkit pm-product-strategy pm-product-discovery pm-market-research pm-data-analytics pm-marketing-growth pm-go-to-market pm-execution pm-ai-shipping; do
  claude plugin install "${plugin}@pm-skills"
done

Installing Selective Plugins

If you only need specific domains, install individual plugins after registering the marketplace. For example, to install only discovery and strategy tools:

claude plugin marketplace add phuryn/pm-skills
claude plugin install pm-product-discovery@pm-skills
claude plugin install pm-product-strategy@pm-skills

Summary

• The PM Skills Marketplace contains nine distinct plugins defined in .claude-plugin/marketplace.json
• Claude Cowork users install via GUI by adding phuryn/pm-skills as a GitHub marketplace, which automatically imports all nine plugins
• Claude Code requires claude plugin marketplace add followed by claude plugin install with the @pm-skills suffix
• Codex CLI uses codex plugin add instead of install for individual plugins
• All methods require the marketplace source to be added once before individual plugin installation

Frequently Asked Questions

What is the difference between Claude Code and Codex CLI installation commands?

Claude Code uses claude plugin install to deploy individual plugins, while Codex CLI uses codex plugin add. Both require the marketplace to be added first with plugin marketplace add phuryn/pm-skills, but the verbs differ when referencing specific plugins from the @pm-skills namespace.

Can I install all nine PM Skills plugins at once without a script?

Currently, no single CLI command installs all plugins simultaneously. You must either use the GUI method in Claude Cowork, which imports all nine automatically, or run individual CLI commands for each plugin. The shell loop provided above automates the CLI approach for batch installation.

Where are the plugin definitions stored in the repository?

The canonical list resides in .claude-plugin/marketplace.json at the repository root. This manifest defines the nine plugin entries, their source directories, and metadata that the CLI tools parse when resolving the @pm-skills namespace according to the phuryn/pm-skills source code.

Do I need to reinstall plugins after updating the repository?

Yes, when the phuryn/pm-skills repository receives updates, you should reinstall the specific plugins to pull the latest skill definitions from the respective SKILL.md files and command workflows stored in each plugin's directory structure.
