How to Install PM Skills for Claude Cowork: Complete Setup Guide

You install PM Skills by adding the phuryn/pm-skills marketplace URL to Claude Cowork, which automatically provisions all nine product-management plugins by reading the central marketplace.yaml manifest.

The PM Skills repository (phuryn/pm-skills) provides a curated marketplace of ready-to-use Claude plugins that add product-management frameworks, commands, and skills to your workspace. To install PM Skills for Claude Cowork, you configure the platform to fetch the plugin marketplace file, which then resolves each plugin's individual configuration and registers them under specific namespaces like pm-toolkit and pm-product-strategy.

Installation Methods for PM Skills

Claude Cowork UI Method (No-Code)

The simplest installation path uses Claude Cowork's visual interface. This approach requires no command-line knowledge and provisions all nine plugins simultaneously.

Follow these steps to add the marketplace:

1️⃣ Open Customize (bottom-left corner)
2️⃣ Navigate to Browse plugins → Personal → +
3️⃣ Select Add marketplace from GitHub
4️⃣ Enter the repository: phuryn/pm-skills

After confirming, Claude Cowork fetches the pm-skills/marketplace.yaml file and automatically downloads the skill and command markdown files for all nine plugin namespaces. The platform then injects these skills into the conversation context immediately, enabling commands like /discover or /strategy without additional configuration.

Claude Code CLI Method

For users preferring command-line control, Claude Code provides equivalent marketplace management with granular plugin installation options.

First, add the marketplace registry:

claude plugin marketplace add phuryn/pm-skills

Then, optionally install individual plugins for specific control:

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

The CLI commands mirror the UI actions internally, resolving each plugin's plugin.yaml configuration and registering them under their respective namespaces.

What Gets Installed: The Nine Plugin Namespaces

When you install PM Skills for Claude Cowork, the platform reads the central marketplace.yaml and provisions the following skill collections:

• pm-toolkit: Core product management utilities and frameworks
• pm-product-strategy: Strategic planning skills including value proposition and SWOT analysis
• pm-product-discovery: Discovery-phase commands like /discover for brainstorming and assumption prioritization
• pm-market-research: Market analysis and competitive intelligence tools
• pm-data-analytics: Data-driven decision making frameworks
• pm-marketing-growth: Growth and marketing strategy skills
• pm-go-to-market: Launch and GTM planning utilities
• pm-execution: Agile execution tools including user stories and retrospectives

Each plugin directory contains a README.md detailing its specific skills—for example, pm-product-strategy/README.md documents strategy-related commands, while pm-execution/README.md covers user stories and retrospectives.

Key Configuration Files in PM Skills

The installation relies on two critical configuration file types within the phuryn/pm-skills repository:

• marketplace.yaml: The root manifest located at pm-skills/marketplace.yaml that lists all nine plugins and their metadata. Claude Cowork reads this file first to determine available plugins.
• plugin.yaml: Individual configuration files within each plugin directory (e.g., pm-toolkit/plugin.yaml) that define specific skills, commands, and file paths for that namespace.

These YAML files work across both Claude Cowork and Claude Code environments, ensuring consistent installation steps regardless of interface.

Summary

• Add the marketplace: Enter phuryn/pm-skills in Claude Cowork's plugin browser or use claude plugin marketplace add phuryn/pm-skills in the CLI.
• Automatic provisioning: The platform reads marketplace.yaml and resolves all nine plugins automatically by downloading their skill and command files.
• Zero code conversion: Skills inject directly into conversation context—no manual configuration required after installation.
• Cross-platform compatibility: The same marketplace configuration works for both Claude Cowork UI and Claude Code CLI.
