How to Add PM Skills to the Claude Cowork Marketplace: A Complete Guide

You can add PM Skills to the Claude Cowork Marketplace by installing the phuryn/pm-skills repository through the Customize panel or by running claude plugin marketplace add phuryn/pm-skills in Claude Code, which automatically registers nine product-management plug-ins with reusable skills and slash-command workflows.

The PM Skills repository is an open-source Claude Cowork Marketplace maintained under phuryn/pm-skills. It bundles nine plug-in packages that expose product-management frameworks directly to Claude Cowork. When you add PM Skills to the Claude Cowork Marketplace, Claude instantly gains commands for product discovery, strategy, execution, and more.

What Is the PM Skills Marketplace?

The PM Skills repository is distributed as a Claude Marketplace that aggregates nine plug-in packages: product-discovery, product-strategy, execution, market-research, data-analytics, go-to-market, marketing-growth, toolkit, and AI-shipping. According to the phuryn/pm-skills source code, each plug-in contains its own metadata, skills, and commands that Claude registers under the product-management category. The root file .claude-plugin/marketplace.json declares the marketplace name, version, and the full list of plug-ins that are installed automatically.

How to Add PM Skills to Claude Cowork

Install via the Claude Cowork UI

The simplest way to add PM Skills is through the built-in marketplace browser.

1. Open Customize in the bottom-left of Claude Cowork.
2. Choose Browse plugins → Personal → +.
3. Select Add marketplace from GitHub.
4. Enter the repository identifier phuryn/pm-skills.

After confirmation, Claude Cowork installs all nine plug-ins automatically.

Install via Claude Code CLI

If you use Claude Code, you can install the marketplace and each plug-in from the terminal. The .claude-plugin/marketplace.json file is used by the CLI to resolve versions and plug-in paths.

# Add the marketplace definition

claude plugin marketplace add phuryn/pm-skills

# Install each plug-in (versions are resolved from the marketplace file)

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

How PM Skills Work After Installation

Once added, Claude reads the marketplace definition and loads every skill and command into your workspace. You can invoke workflows with slash commands or let Claude auto-load individual skills on demand.

Running Slash Commands

Slash commands chain one or more skills into end-to-end workflows. For example, typing the following triggers the product-discovery plug-in:

/discover AI-powered meeting summarizer for remote teams

This command runs a predefined skill chain defined in the repository:

1. brainstorm-ideas-new
2. identify-assumptions-new
3. prioritize-assumptions
4. brainstorm-experiments-new

These steps are cataloged in the pm-product-discovery plug-in documentation (see pm-product-discovery/README.md).

Invoking a Skill Directly

You can also call a skill without running a full command chain. For example, the toolkit plug-in exposes a resume-review skill:

/review-resume [attach your PM resume PDF]

When invoked, Claude loads pm-toolkit/skills/review-resume/SKILL.md and returns a structured review based on the ten best-practice checklist defined in that file. The wrapper command is declared in pm-toolkit/commands/review-resume.md.

Key Files in the Repository

Understanding the source layout helps you debug or extend the marketplace. The following files define how PM Skills are registered and executed:

• .claude-plugin/marketplace.json — Central marketplace definition that lists every plug-in name, version, and source path.
• pm-toolkit/.claude-plugin/plugin.json — Plug-in metadata for the toolkit package, including author and keyword tags.
• pm-toolkit/skills/review-resume/SKILL.md — On-demand knowledge unit for the resume-review framework.
• pm-toolkit/commands/review-resume.md — Slash-command definition that surfaces the resume-review skill to users.
• pm-product-discovery/README.md — Catalog of discovery-specific skills and commands referenced by the /discover workflow.

Summary

• The PM Skills marketplace lives in the phuryn/pm-skills repository and ships as a single Claude Cowork Marketplace bundle.
• Adding it via the UI requires only the GitHub identifier phuryn/pm-skills under Customize → Browse plugins.
• Adding it via CLI uses claude plugin marketplace add phuryn/pm-skills followed by individual claude plugin install commands for each plug-in.
• Claude loads the central .claude-plugin/marketplace.json file to resolve plug-ins, then registers every skill markdown and command under the product-management category.
• Users interact with installed frameworks through slash commands like /discover and /review-resume.

Frequently Asked Questions

What plug-ins are included in the PM Skills marketplace?

The marketplace bundles nine plug-ins: product-discovery, product-strategy, execution, market-research, data-analytics, go-to-market, marketing-growth, toolkit, and AI-shipping. Each plug-in is declared in .claude-plugin/marketplace.json and installed automatically when you add the marketplace to Claude Cowork.

Can I install individual PM Skills plug-ins without the full marketplace?

Yes. The installation instructions in the repository README show that you can install individual packages by running claude plugin install <package-name>@pm-skills in Claude Code. This gives you granular control if you only need a specific workflow like pm-toolkit or pm-product-discovery.

How do slash commands differ from skills in Claude Cowork?

Skills are reusable knowledge units defined in SKILL.md files (for example, pm-toolkit/skills/review-resume/SKILL.md) that Claude loads on demand. Slash commands are user-facing triggers stored in commands/*.md files that chain one or more skills into an end-to-end workflow, such as /discover or /review-resume.

Is PM Skills compatible with Claude Code as well as Claude Cowork?

Yes. The repository README includes installation steps for both interfaces. Claude Cowork users add the marketplace through the Customize panel, while Claude Code users run the claude plugin marketplace add and claude plugin install commands to register the same set of plug-ins.
