# How to Install PM Skills Plugins in Claude Cowork: Step-by-Step Guide > Easily install PM Skills plugins in Claude Cowork using our step-by-step guide. Enhance your workflow by adding the phuryn/pm-skills repository today. - Repository: [Pawel Huryn/pm-skills](https://github.com/phuryn/pm-skills) - Tags: how-to-guide - Published: 2026-07-10 --- **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`](https://github.com/phuryn/pm-skills/blob/main/.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: ```text 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`](https://github.com/phuryn/pm-skills/blob/main/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`](https://github.com/phuryn/pm-skills/blob/main/.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: ```text /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: ```bash # 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. ## Summary - **One-step installation**: Add `phuryn/pm-skills` via Customize → Browse plugins → Personal → Add marketplace from GitHub. - **Nine plugins included**: The marketplace automatically installs all plugins defined in [`.claude-plugin/marketplace.json`](https://github.com/phuryn/pm-skills/blob/main/.claude-plugin/marketplace.json), including `pm-toolkit`, `pm-execution`, and `pm-product-discovery`. - **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`](https://github.com/phuryn/pm-skills/blob/main/.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`](https://github.com/phuryn/pm-skills/blob/main/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`](https://github.com/phuryn/pm-skills/blob/main/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.
