Access 9 product management plugins with domain-specific skills and slash commands. Follow our complete guide. - Repository: [Pawel Huryn/pm-skills](https://github.com/phuryn/pm-skills) - Tags: how-to-guide - Published: 2026-07-04 --- **Add the repository `phuryn/pm-skills` to Claude Cowork via the Customize menu or CLI to instantly access 9 product management plugins bundled with domain-specific skills and slash commands.** The **PM Skills Marketplace** is a curated collection of Claude Cowork plugins designed specifically for product management workflows. By installing this marketplace from the `phuryn/pm-skills` repository, you gain immediate access to nine distinct plugins—including `pm-toolkit`, `pm-execution`, and `pm-product-discovery`—without needing to install each component individually. This guide covers both the UI-based installation for Claude Cowork and the CLI method for Claude Code, referencing the actual source structure and configuration files that power the integration. ## Installation via Claude Cowork UI The fastest way to install PM Skills Marketplace plugins is through the Claude Cowork graphical interface. This method automatically resolves all nine plugins defined in [`.claude-plugin/marketplace.json`](https://github.com/phuryn/pm-skills/blob/main/.claude-plugin/marketplace.json) and registers their commands in your workspace. ### Step-by-Step Installation Follow these steps to add the marketplace to your Claude Cowork environment: 1. **Open Claude Cowork** and locate the **Customize** button in the bottom-left corner of the interface. 2. Select **Browse plugins**, then navigate to the **Personal** tab. 3. Click the **+** (Add plugin) button. 4. Choose **Add marketplace from GitHub**. 5. Enter the repository identifier: ```text phuryn/pm-skills ``` 6. Confirm the addition and wait for the installation to complete. Once the spinner finishes, Claude Cowork downloads the marketplace definition from [`.claude-plugin/marketplace.json`](https://github.com/phuryn/pm-skills/blob/main/.claude-plugin/marketplace.json) (lines 11-66) and automatically registers all nine plugins. You can verify the installation by typing any slash command, such as `/discover`, into the chat interface. ## Installation via Command Line Interface For users running **Claude Code** or preferring terminal-based workflows, you can install the marketplace using the CLI. This approach provides granular control over plugin installation. ### Add the Full Marketplace To register the entire marketplace and make all nine plugins available: ```bash claude plugin marketplace add phuryn/pm-skills ``` ### Install Individual Plugins After adding the marketplace, you can install specific plugins rather than the entire bundle. For example, to install only the toolkit plugin: ```bash claude plugin install pm-toolkit@pm-skills ``` This method references the plugin definitions stored in subdirectories like `pm-toolkit/` and `pm-execution/`, as documented in the repository's [`README.md`](https://github.com/phuryn/pm-skills/blob/main/README.md) (lines 64-80). ## What Gets Installed: The Nine Plugins When you install the PM Skills Marketplace, Claude Cowork pulls nine distinct plugin packages, each containing specialized skills and commands: - **pm-toolkit**: Core product management utilities and resume review tools - **pm-execution**: Sprint planning and delivery management workflows - **pm-product-discovery**: User research and discovery lifecycle management - **pm-strategy**: Product strategy canvas and roadmap generation - **pm-prd**: Feature specification and requirements documentation - **pm-launch**: Go-to-market planning and launch coordination - **pm-metrics**: Analytics and success metric definition - **pm-stakeholder**: Communication and alignment frameworks - **pm-career**: Career development and interview preparation Each plugin follows a standardized structure with `skills/` directories containing markdown knowledge modules and `commands/` directories defining slash-command workflows. ## Using Installed Plugins: Available Commands After installation, the marketplace registers numerous slash commands in Claude Cowork's command registry. These commands chain multiple skills together to execute complex workflows. **Key commands available immediately:** - `/discover` — Run a full product-discovery workflow - `/strategy` — Create a product-strategy canvas - `/write-prd` — Generate a PRD from a feature idea - `/plan-launch` — Build a GTM launch plan - `/review-resume` — Analyze and optimize product management resumes When you invoke `/discover AI-powered meeting summarizer for remote teams`, Claude Cowork automatically loads the underlying skills from `pm-product-discovery/skills/` and guides you through the discovery lifecycle without requiring manual skill selection. ## Architecture and File Structure Understanding how the PM Skills Marketplace integrates with Claude Cowork helps troubleshoot issues and customize workflows. ### Marketplace Definition The **marketplace manifest** at [`.claude-plugin/marketplace.json`](https://github.com/phuryn/pm-skills/blob/main/.claude-plugin/marketplace.json) serves as the entry point. This JSON file lists all nine plugins, their source directories, and categorical metadata. Claude Cowork reads this file during installation to determine which plugin folders to pull from the repository. ### Plugin Package Structure Each plugin resides in its own subdirectory (e.g., `pm-toolkit/`, `pm-execution/`) and contains: - **`skills/`** — Reusable knowledge modules written in markdown (e.g., [`pm-toolkit/skills/review-resume/SKILL.md`](https://github.com/phuryn/pm-skills/blob/main/pm-toolkit/skills/review-resume/SKILL.md)) - **`commands/`** — Claude-specific slash-command definitions that orchestrate skills (e.g., [`pm-toolkit/commands/review-resume.md`](https://github.com/phuryn/pm-skills/blob/main/pm-toolkit/commands/review-resume.md)) ### Skills vs. Commands **Skills** are atomic knowledge units that can be invoked directly using the syntax `/plugin-name:skill-name` or automatically by commands. **Commands** are user-facing workflows that chain multiple skills together. For example, the `/write-prd` command might sequentially invoke skills for user-story generation, acceptance criteria definition, and technical requirement gathering. ## Summary - **Install via UI**: Use Customize → Browse plugins → Personal → + → Add marketplace from GitHub → enter `phuryn/pm-skills` - **Install via CLI**: Run `claude plugin marketplace add phuryn/pm-skills` for the full bundle or `claude plugin install pm-toolkit@pm-skills` for specific tools - **Automatic Registration**: The marketplace JSON at [`.claude-plugin/marketplace.json`](https://github.com/phuryn/pm-skills/blob/main/.claude-plugin/marketplace.json) (lines 11-66) defines all nine plugins, which are fetched and registered automatically - **Immediate Usage**: Access 9 plugins with commands like `/discover`, `/strategy`, and `/write-prd` immediately after installation completes - **No Configuration Required**: Claude Cowork handles skill loading and command registration automatically based on the repository structure ## Frequently Asked Questions ### Do I need to install each plugin individually after adding the marketplace? No. When you add the `phuryn/pm-skills` repository as a marketplace, Claude Cowork reads the [`.claude-plugin/marketplace.json`](https://github.com/phuryn/pm-skills/blob/main/.claude-plugin/marketplace.json) file and automatically installs all nine plugins listed in the manifest. You only need to install individual plugins if you initially added the repository via CLI and want to select specific tools rather than the full bundle. ### Can I use these plugins in standard Claude Code without Cowork? Yes. The plugins work in standard Claude Code environments through the CLI installation method. Use `claude plugin marketplace add phuryn/pm-skills` to register the marketplace, then invoke commands using the slash-command syntax. The underlying skills and commands function identically regardless of whether you use the Cowork UI or the command-line interface. ### Where are the skill definitions stored in the repository? Each plugin stores its skills in dedicated `skills/` subdirectories. For example, the resume review skill resides at [`pm-toolkit/skills/review-resume/SKILL.md`](https://github.com/phuryn/pm-skills/blob/main/pm-toolkit/skills/review-resume/SKILL.md). These markdown files contain the domain-specific knowledge that Claude uses when executing commands. You can reference these files directly to understand the exact prompting logic and knowledge boundaries for each capability. ### How do I update the plugins when the repository changes? Claude Cowork periodically checks for updates to registered marketplaces. When the `phuryn/pm-skills` repository updates its [`marketplace.json`](https://github.com/phuryn/pm-skills/blob/main/marketplace.json) or plugin definitions, your installation will sync automatically. For CLI users, run `claude plugin marketplace update phuryn/pm-skills` to pull the latest versions of the skills and commands defined in the repository.
