# How to Install pm-skills in Claude Code vs Claude Cowork: Complete Setup Guide > Learn to install pm-skills in Claude Code and Claude Cowork with our easy setup guide. Follow UI or CLI steps for a quick installation. - Repository: [Pawel Huryn/pm-skills](https://github.com/phuryn/pm-skills) - Tags: how-to-guide - Published: 2026-06-27 --- **You can install pm-skills in Claude Cowork via the UI's Customize menu by adding the marketplace from GitHub, or in Claude Code using the CLI commands `claude plugin marketplace add` and `claude plugin install` for individual plugins.** The **pm-skills** marketplace from the `phuryn/pm-skills` repository distributes nine specialized product management plugins for Anthropic's Claude environments. Whether you use the graphical Claude Cowork interface or the terminal-based Claude Code CLI, the installation workflows differ significantly. This guide covers the exact steps for each environment based on the repository's official documentation. ## Installing pm-skills in Claude Cowork Claude Cowork provides a graphical interface recommended for non-developers. According to the repository's [`README.md`](https://github.com/phuryn/pm-skills/blob/main/README.md) (lines 52-58), installation requires adding the marketplace through the UI's Customize menu. ### Step-by-Step Installation 1. Open **Customize** in the bottom-left corner of the Claude Cowork interface. 2. Select **Browse plugins**, then navigate to **Personal**, and click **+**. 3. Choose **Add marketplace from GitHub**. 4. Enter the repository identifier **`phuryn/pm-skills`** and confirm. All nine plugins—including **pm-toolkit**, **pm-product-strategy**, **pm-product-discovery**, **pm-market-research**, **pm-data-analytics**, **pm-marketing-growth**, **pm-go-to-market**, **pm-execution**, and **pm-ai-shipping**—install automatically. This gives you immediate access to slash commands like `/discover` and `/strategy` directly in the chat interface. ## Installing pm-skills in Claude Code Claude Code requires CLI commands to manage plugins. The installation process documented in [`README.md`](https://github.com/phuryn/pm-skills/blob/main/README.md) (lines 63-79) involves two phases: adding the marketplace source, then selecting individual plugins. ### Add the Marketplace First, register the pm-skills marketplace with your Claude Code installation: ```bash claude plugin marketplace add phuryn/pm-skills ``` ### Install Individual Plugins Unlike Cowork's automatic batch installation, Claude Code requires you to install each plugin individually. Install all nine plugins or only the ones you need: ```bash 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 ``` ### Key Difference in Usage While both environments use the same underlying skill files found in [`CLAUDE.md`](https://github.com/phuryn/pm-skills/blob/main/CLAUDE.md) and individual plugin directories like [`pm-execution/commands/write-prd.md`](https://github.com/phuryn/pm-skills/blob/main/pm-execution/commands/write-prd.md), Claude Code does **not** expose slash commands. Instead, you invoke workflows by describing steps in plain language. ## Usage Examples After installation, the two environments handle skill invocation differently. ### Claude Cowork Usage Use built-in slash commands directly in the chat interface: ```text /discover AI-powered meeting summarizer for remote teams ``` ### Claude Code Usage Describe the workflow naturally without slash prefixes: ```text Run product discovery on my new AI-assistant idea: brainstorm ideas, map assumptions, prioritize the risky ones, then design experiments. ``` For specific skill tasks documented in files like [`pm-execution/commands/write-prd.md`](https://github.com/phuryn/pm-skills/blob/main/pm-execution/commands/write-prd.md), simply state the objective: ```text Create a PRD for a notification system that reduces alert fatigue. ``` Or for data analytics tasks: ```text Write a BigQuery SQL query that returns monthly active users by country for Q4 2025. ``` ## Key Configuration Files Understanding these repository files helps troubleshoot installation issues: - **[`README.md`](https://github.com/phuryn/pm-skills/blob/main/README.md)**: Contains the complete installation guide referenced in lines 52-58 (Cowork) and lines 63-79 (Claude Code). - **[`CLAUDE.md`](https://github.com/phuryn/pm-skills/blob/main/CLAUDE.md)**: Defines agent behavior and Claude-specific conventions that both environments use. - **[`pm-toolkit/README.md`](https://github.com/phuryn/pm-skills/blob/main/pm-toolkit/README.md)**: Shows how individual plugins group skills and commands. - **[`pm-ai-shipping/README.md`](https://github.com/phuryn/pm-skills/blob/main/pm-ai-shipping/README.md)**: Demonstrates the packaging structure for the AI-shipping plugin. ## Summary - **Claude Cowork** installs all nine pm-skills plugins automatically via the UI's Customize menu using the GitHub identifier `phuryn/pm-skills`. - **Claude Code** requires two CLI steps: `claude plugin marketplace add phuryn/pm-skills` followed by individual `claude plugin install` commands for each plugin. - Cowork exposes **slash commands** (e.g., `/discover`), while Claude Code requires **plain language prompts** to invoke the same underlying skills. - Both environments reference the same source files, including [`CLAUDE.md`](https://github.com/phuryn/pm-skills/blob/main/CLAUDE.md) for behavior definitions and individual plugin directories like `pm-execution/commands/` for specific workflows. ## Frequently Asked Questions ### Can I install only specific pm-skills plugins instead of all nine? In **Claude Cowork**, all nine plugins install automatically when you add the marketplace. In **Claude Code**, you have granular control—simply omit the `claude plugin install` commands for any plugins you don't need. The CLI approach lets you install only pm-toolkit and pm-execution, for example, while skipping pm-ai-shipping if desired. ### Why don't slash commands work in Claude Code? Claude Code does not expose the slash-command interface that Claude Cowork uses. According to the repository documentation, you must invoke skills by describing the workflow in natural language, such as "Create a PRD" or "Run product discovery." The underlying skill files in [`pm-execution/commands/write-prd.md`](https://github.com/phuryn/pm-skills/blob/main/pm-execution/commands/write-prd.md) and similar paths remain accessible, but without the `/` prefix trigger. ### Do I need to reinstall pm-skills after updating Claude Code or Cowork? The pm-skills marketplace persists across Claude environment updates once installed via `claude plugin marketplace add` or the Cowork UI. However, if individual plugins receive updates, you may need to run `claude plugin update` in the CLI or check for marketplace updates in Cowork's Customize section. The repository's [`README.md`](https://github.com/phuryn/pm-skills/blob/main/README.md) (lines 63-79) outlines update procedures for the CLI. ### Where are the pm-skills workflow definitions stored? The skill definitions reside in the `phuryn/pm-skills` repository's plugin directories. For example, [`pm-execution/commands/write-prd.md`](https://github.com/phuryn/pm-skills/blob/main/pm-execution/commands/write-prd.md) contains the PRD writing workflow, while [`CLAUDE.md`](https://github.com/phuryn/pm-skills/blob/main/CLAUDE.md) serves as the single source of truth for agent behavior conventions. Both Claude Code and Cowork reference these files when executing tasks.
