How to Get Started with PM Skills Marketplace on Claude Cowork: A Complete Setup Guide

Install the PM Skills Marketplace on Claude Cowork by adding the GitHub repository phuryn/pm-skills through the Customize → Browse plugins → Personal menu, then invoke slash commands like /discover to run AI-driven product management workflows.

The PM Skills Marketplace on Claude Cowork transforms the phuryn/pm-skills repository into a plug-and-play AI operating system for product managers. This marketplace bundles nine specialized plugins—each containing domain-specific skills and slash-triggered commands—that automate workflows from initial discovery to launch planning. By installing the marketplace once, Claude Cowork automatically loads all frameworks encoded in markdown files, making advanced product management methodologies instantly accessible without writing any code.

Installation Steps: Adding the Marketplace to Claude Cowork

Getting started requires only a one-time installation through the Claude Cowork UI. The platform automatically fetches the marketplace file and registers all nine plugins.

1. Open Claude Cowork and click the Customize button in the bottom-left corner.

2. Select Browse plugins → Personal → +.

3. Choose Add marketplace from GitHub and paste the repository identifier:

   phuryn/pm-skills

4. Confirm the installation. Claude Cowork will fetch the marketplace configuration and load all nine plugin folders (including pm-toolkit, pm-product-strategy, pm-product-discovery, and pm-ai-shipping).

Once installed, the marketplace requires no additional configuration. The skills are available implicitly when Claude detects relevant queries, while commands are ready to invoke via slash syntax.

Understanding the Architecture: Skills vs. Commands

The repository organizes functionality into two distinct layers that work together to deliver end-to-end workflows.

Skills: Implicit Domain Knowledge

Skills are individual markdown files located at */skills/*/SKILL.md that encode frameworks, questionnaires, or reference materials. For example, pm-product-discovery/skills/brainstorm-ideas-new/SKILL.md contains a structured ideation framework. These files auto-load when Claude detects a relevant user query—you do not invoke them directly. The repository also includes standalone utility skills like pm-toolkit/skills/review-resume/SKILL.md for specific tasks.

Commands: Slash-Triggered Workflows

Commands are markdown files located at */commands/*.md that chain multiple skills into complete workflows. They are explicitly invoked using /command-name syntax. Each command orchestrates the underlying skills to produce step-by-step outputs. For instance, invoking /discover executes a sequential workflow defined in pm-product-discovery/commands/discover.md that runs through ideation, assumption mapping, prioritization, and experiment design.

Running Your First Command

After installation, test the marketplace by running a full product discovery cycle. Enter the following into Claude Cowork:

/discover AI-powered meeting summarizer for remote teams

Claude will automatically execute the four underlying skills defined in pm-product-discovery/commands/discover.md: brainstorming ideas, identifying assumptions, prioritizing assumptions, and designing experiments. The output appears as a structured, step-by-step conversation requiring no manual prompting.

Essential Commands for Product Management

The marketplace provides specialized commands across the product lifecycle. These workflows are defined in specific command files within the repository structure.

Command	Source File	Purpose
/discover	pm-product-discovery/commands/discover.md	Runs a complete discovery cycle including ideation and assumption testing.
/write-prd	pm-execution/commands/write-prd.md	Generates an 8-section Product Requirements Document (problem, solution, metrics, etc.).
/plan-launch	pm-go-to-market/commands/plan-launch.md	Creates a GTM strategy with beachhead segmentation, ICP definition, and launch timeline.

You can also query the raw skill definitions directly. Asking "What does the 'brainstorm-ideas-new' skill do?" prompts Claude to reference pm-product-discovery/skills/brainstorm-ideas-new/SKILL.md and explain the framework.

Key Source Files to Explore

Understanding the repository structure helps you customize or extend the marketplace functionality. These files represent the canonical source of truth:

• README.md – High-level overview and installation instructions for the marketplace.
• CLAUDE.md – Canonical instructions for Claude-based agents consuming this repository.
• pm-product-discovery/commands/discover.md – Concrete definition of the most common entry-point command.
• pm-execution/commands/write-prd.md – The PRD generation workflow definition.
• pm-go-to-market/commands/plan-launch.md – The launch planning workflow definition.

Summary

• Install the marketplace by adding phuryn/pm-skills via Claude Cowork's Customize → Browse plugins → Personal menu.
• The marketplace automatically loads 9 plugins containing skills and commands.
• Skills reside in */skills/*/SKILL.md files and load implicitly; commands reside in */commands/*.md files and trigger via /command-name.
• Use /discover, /write-prd, and /plan-launch to execute complete product management workflows immediately after installation.

Frequently Asked Questions

What is the PM Skills Marketplace on Claude Cowork?

The PM Skills Marketplace on Claude Cowork is an AI operating system that bundles nine plugins from the phuryn/pm-skills repository. It provides pre-built product management frameworks as markdown-based skills and slash-triggered commands that automate workflows like discovery, PRD writing, and launch planning.

What is the difference between skills and commands in the marketplace?

Skills are individual knowledge files (e.g., pm-toolkit/skills/review-resume/SKILL.md) that Claude loads automatically when relevant to your query. Commands are workflow files (e.g., pm-product-discovery/commands/discover.md) that you invoke manually with /command-name to execute multi-step processes chaining multiple skills together.

Where are the skill definitions stored in the repository?

Skill definitions are stored as markdown files following the path pattern */skills/*/SKILL.md within each plugin directory. For example, the brainstorming skill is located at pm-product-discovery/skills/brainstorm-ideas-new/SKILL.md, while the resume review skill is at pm-toolkit/skills/review-resume/SKILL.md.
