Prerequisites for Using the PM Skills Marketplace: Complete Setup Guide

You need a supported Claude environment (Claude Cowork web UI or Claude Code CLI), access to the phuryn/pm-skills GitHub repository, and optionally the CLI tools installed to use the PM Skills Marketplace.

The PM Skills Marketplace is a collection of AI-driven plugins designed for product managers. Hosted in the public GitHub repository phuryn/pm-skills, this marketplace provides 68+ skills and 42+ chained workflows that integrate directly with Claude. Before you can access commands like /discover or /write-prd, you must satisfy several technical prerequisites that enable the plugin system to function.

Required Prerequisites for the PM Skills Marketplace

Supported Claude Environment

Only two runtimes can load the marketplace plugins and expose the /command workflows: Claude Cowork (the web UI) and Claude Code (the CLI). According to the source code in README.md (lines 52-58), these are the only supported environments for running the AI-driven plugins.

Access to the Marketplace Repository

The marketplace lives in the public GitHub repo phuryn/pm-skills. The CLI pulls plugin definitions directly from this repository during installation, as documented in README.md (lines 65-78). You need read access to this public repository to fetch the plugin packages.

CLI Tools (Optional but Recommended)

While you can use the web UI, installing Claude Code or Codex CLI on your local machine provides the most flexible workflow. Both CLIs can add the marketplace and install individual plugins via claude plugin commands, as implemented in README.md (lines 63-78).

Internet Connectivity and Authentication

You need active internet connectivity to fetch plugin packages from GitHub. Additionally, the CLI commands require authentication to the Claude service—you must be logged in before running install steps.

Installation Methods

Claude Cowork (No-Code UI)

For users preferring a graphical interface, follow these steps in the Claude Cowork web UI:

1. Open Customize (bottom-left corner).
2. Navigate to Browse plugins → Personal → +.
3. Choose Add marketplace from GitHub and enter phuryn/pm-skills.

This automatically installs all nine plugins, exposing skills and slash-commands such as /discover, /strategy, and /write-prd.

Claude Code (CLI)

For command-line users, execute these commands in your terminal:

# Step 1 – add the marketplace

claude plugin marketplace add phuryn/pm-skills

# Step 2 – install the individual plugins you need

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

After installing a plugin, you can immediately invoke its commands, such as /discover AI-powered meeting summarizer.

Key Components and File Structure

Understanding the repository structure helps navigate the available skills. The README.md file serves as the central documentation containing installation steps and the complete plugin list. The repository organizes skills into nine distinct plugin directories:

• pm-toolkit/ – Core utility skills including resume review, NDA drafting, privacy policy generation, and grammar checking.
• pm-product-strategy/ – Strategy-focused capabilities such as vision crafting, business model canvas, pricing strategy, and SWOT analysis.
• pm-product-discovery/ – Discovery skills including brainstorming, assumption mapping, opportunity solution trees (OST), and interview script generation.
• pm-go-to-market/ – Go-to-market skills covering ideal customer profile development, GTM strategy, and competitive battlecards.
• pm-execution/ – Execution skills for user stories, PRD creation, test scenarios, and sprint planning.
• pm-ai-shipping/ – Shipping-focused skills including artifact shipping, security audits, and performance audits.

These directories contain the full skill definitions; once prerequisites are met, the Claude environment loads these plugins to make 68+ skills available.

Summary

• You must use Claude Cowork or Claude Code – these are the only supported environments that can load the marketplace plugins and expose /command workflows.
• Repository access is required – the CLI pulls plugin definitions directly from the public phuryn/pm-skills GitHub repository.
• CLI installation is optional but recommended – installing Claude Code or Codex CLI enables the claude plugin commands for managing individual plugins.
• Authentication and connectivity are mandatory – you need internet access to fetch packages from GitHub and must be logged into your Claude account to execute CLI commands.
• Nine plugins available – the marketplace includes pm-toolkit, pm-product-strategy, pm-product-discovery, pm-market-research, pm-data-analytics, pm-marketing-growth, pm-go-to-market, pm-execution, and pm-ai-shipping.

Frequently Asked Questions

Do I need to install all nine plugins to use the PM Skills Marketplace?

No. While adding the marketplace via Claude Cowork installs all nine plugins automatically, you can selectively install individual plugins using the CLI. Run claude plugin install followed by the specific plugin name (e.g., pm-product-strategy@pm-skills) to install only the capabilities you need, as documented in the repository's README.md.

Can I use the PM Skills Marketplace without installing the Claude Code CLI?

Yes. The marketplace supports Claude Cowork, the web-based UI, which requires no local installation. Navigate to Customize → Browse plugins → Personal → +, then add the marketplace from GitHub using the repository name phuryn/pm-skills to access all skills immediately.

What happens if I lose internet connectivity during plugin installation?

The installation will fail. According to the source code in README.md, internet connectivity is required to fetch plugin packages from GitHub during installation. The CLI pulls plugin definitions directly from the phuryn/pm-skills repository, so a stable connection is mandatory when running claude plugin marketplace add or installing individual plugins.

Do I need a specific type of Claude account to use the marketplace?

Yes. You need a valid Claude or Codex account, and you must be logged in before running CLI install steps. The CLI commands require authentication to the Claude service to function properly, as noted in the repository documentation.
