How to Install PM Skills Plugins in Claude Cowork: Step-by-Step Guide

To install PM Skills plugins in Claude Cowork, open the Customize menu, navigate to Browse plugins → Personal, click Add, select "Add marketplace from GitHub," and enter the repository identifier phuryn/pm-skills.

The PM Skills Marketplace is a curated collection of nine product management plugins designed for Claude Code and Cowork environments. Hosted in the phuryn/pm-skills repository, this marketplace bundles domain-specific skills and slash commands that streamline product discovery, execution, and strategy workflows. Once added, Claude Cowork automatically registers all nine plugins, giving you immediate access to tools like /discover and /write-prd without individual installations.

Installing PM Skills via the Claude Cowork Interface

The Claude Cowork UI provides the fastest path to installing the entire PM Skills Marketplace. The process fetches the marketplace definition from .claude-plugin/marketplace.json (lines 11-66) and registers all bundled plugins automatically.

Open the Plugin Browser

Launch Claude Cowork and locate the Customize button in the bottom-left corner of the interface. Click it to open the customization panel, then select Browse plugins to view available plugin sources.

Add the Marketplace from GitHub

Navigate to the Personal tab and click the + (Add plugin) button. From the installation options, choose Add marketplace from GitHub. In the repository identifier field, enter:

phuryn/pm-skills

Confirm the entry. Claude Cowork will download the marketplace manifest and install all nine plugins automatically, as documented in the repository's README.md (lines 53-60).

Verify Installation

After the installation spinner completes, the plugins are immediately active. You can verify successful registration by typing / in the chat interface to see the new slash commands appear in the autocomplete menu.

What Gets Installed: The Nine Plugin Structure

The PM Skills Marketplace uses a hierarchical structure defined in .claude-plugin/marketplace.json. When you add phuryn/pm-skills, Claude Cowork resolves and installs the following nine plugin packages:

• pm-toolkit – Core product management utilities
• pm-execution – Delivery and sprint management tools
• pm-product-discovery – Research and validation workflows
• Plus six additional specialized plugins

Each plugin follows a consistent directory structure containing skills/ (reusable knowledge modules) and commands/ (slash-command definitions). For example, the pm-toolkit plugin stores skill definitions in pm-toolkit/skills/ and command triggers in pm-toolkit/commands/.

Using PM Skills Commands After Installation

Once installed, you can invoke any of the bundled commands directly in Claude Cowork. These commands chain multiple skills to execute complex workflows:

/discover AI-powered meeting summarizer for remote teams
/strategy
/write-prd
/plan-launch

The /discover command initiates a full product-discovery workflow, while /write-prd generates a Product Requirements Document from your feature ideas. Claude Cowork automatically loads the required skills from the respective plugin directories (e.g., pm-product-discovery/skills/) when you trigger these commands.

Alternative: CLI Installation Method

While the UI method is recommended, you can also install the marketplace via Claude Code CLI for automation or scripting purposes:

# Add the entire marketplace

claude plugin marketplace add phuryn/pm-skills

# Install specific plugins individually

claude plugin install pm-toolkit@pm-skills

This approach references the same phuryn/pm-skills repository but allows selective plugin installation for advanced users.

• Immediate availability: Commands like /discover and /write-prd are available instantly without additional configuration.
• Dual access: Skills can be invoked indirectly through commands or directly via /plugin-name:skill-name syntax.
• Source structure: Each plugin contains skills/ (markdown knowledge) and commands/ (slash-command triggers) directories.

Frequently Asked Questions

What specific plugins are included in the PM Skills Marketplace?

The marketplace bundles nine plugins: pm-toolkit, pm-execution, pm-product-discovery, and six additional specialized packages. Each plugin targets specific product management domains such as strategy, delivery, or user research. The complete list is defined in .claude-plugin/marketplace.json at the repository root.

Can I install individual PM Skills plugins without the full marketplace?

Yes, though the UI method installs all nine plugins by default. If you need selective installation, use the CLI method with claude plugin install pm-toolkit@pm-skills, replacing pm-toolkit with your desired plugin name. This fetches only that plugin's skills/ and commands/ directories from the phuryn/pm-skills repository.

Where are the skill definitions stored in the repository?

Skill definitions reside in markdown files within each plugin's skills/ directory. For example, the resume review skill is located at pm-toolkit/skills/review-resume/SKILL.md. Commands that reference these skills are stored in the corresponding commands/ directory, such as pm-toolkit/commands/review-resume.md.

Do I need to restart Claude Cowork after installing the PM Skills plugins?

No restart is required. Once the marketplace installation completes and the spinner stops, all nine plugins and their slash commands are immediately registered in the assistant's command registry. You can begin using /discover, /strategy, or any other bundled command right away.
