# Prerequisites for Using the PM Skills Marketplace: Complete Setup Guide > Learn the essential prerequisites for the PM Skills Marketplace with this complete setup guide. Discover Claude environment, GitHub access, and CLI tool requirements. - Repository: [Pawel Huryn/pm-skills](https://github.com/phuryn/pm-skills) - Tags: how-to-guide - Published: 2026-06-26 --- **You need a supported Claude environment (Claude Cowork web UI or Claude Code CLI), access to the phuryn/pm-skills GitHub repository, and optionally the CLI tools installed to use the PM Skills Marketplace.** The PM Skills Marketplace is a collection of AI-driven plugins designed for product managers. Hosted in the public GitHub repository `phuryn/pm-skills`, this marketplace provides 68+ skills and 42+ chained workflows that integrate directly with Claude. Before you can access commands like `/discover` or `/write-prd`, you must satisfy several technical prerequisites that enable the plugin system to function. ## Required Prerequisites for the PM Skills Marketplace ### Supported Claude Environment Only two runtimes can load the marketplace plugins and expose the `/command` workflows: **Claude Cowork** (the web UI) and **Claude Code** (the CLI). According to the source code in [`README.md`](https://github.com/phuryn/pm-skills/blob/main/README.md) (lines 52-58), these are the only supported environments for running the AI-driven plugins. ### Access to the Marketplace Repository The marketplace lives in the public GitHub repo `phuryn/pm-skills`. The CLI pulls plugin definitions directly from this repository during installation, as documented in [`README.md`](https://github.com/phuryn/pm-skills/blob/main/README.md) (lines 65-78). You need read access to this public repository to fetch the plugin packages. ### CLI Tools (Optional but Recommended) While you can use the web UI, installing **Claude Code** or **Codex** CLI on your local machine provides the most flexible workflow. Both CLIs can add the marketplace and install individual plugins via `claude plugin` commands, as implemented in [`README.md`](https://github.com/phuryn/pm-skills/blob/main/README.md) (lines 63-78). ### Internet Connectivity and Authentication You need active internet connectivity to fetch plugin packages from GitHub. Additionally, the CLI commands require authentication to the Claude service—you must be logged in before running install steps. ## Installation Methods ### Claude Cowork (No-Code UI) For users preferring a graphical interface, follow these steps in the Claude Cowork web UI: 1. Open **Customize** (bottom-left corner). 2. Navigate to **Browse plugins → Personal → +**. 3. Choose **Add marketplace from GitHub** and enter `phuryn/pm-skills`. This automatically installs all nine plugins, exposing skills and slash-commands such as `/discover`, `/strategy`, and `/write-prd`. ### Claude Code (CLI) For command-line users, execute these commands in your terminal: ```bash # Step 1 – add the marketplace claude plugin marketplace add phuryn/pm-skills # Step 2 – install the individual plugins you need 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 ``` After installing a plugin, you can immediately invoke its commands, such as `/discover AI-powered meeting summarizer`. ## Key Components and File Structure Understanding the repository structure helps navigate the available skills. The [`README.md`](https://github.com/phuryn/pm-skills/blob/main/README.md) file serves as the central documentation containing installation steps and the complete plugin list. The repository organizes skills into nine distinct plugin directories: - **`pm-toolkit/`** – Core utility skills including resume review, NDA drafting, privacy policy generation, and grammar checking. - **`pm-product-strategy/`** – Strategy-focused capabilities such as vision crafting, business model canvas, pricing strategy, and SWOT analysis. - **`pm-product-discovery/`** – Discovery skills including brainstorming, assumption mapping, opportunity solution trees (OST), and interview script generation. - **`pm-go-to-market/`** – Go-to-market skills covering ideal customer profile development, GTM strategy, and competitive battlecards. - **`pm-execution/`** – Execution skills for user stories, PRD creation, test scenarios, and sprint planning. - **`pm-ai-shipping/`** – Shipping-focused skills including artifact shipping, security audits, and performance audits. These directories contain the full skill definitions; once prerequisites are met, the Claude environment loads these plugins to make 68+ skills available. ## Summary - **You must use Claude Cowork or Claude Code** – these are the only supported environments that can load the marketplace plugins and expose `/command` workflows. - **Repository access is required** – the CLI pulls plugin definitions directly from the public `phuryn/pm-skills` GitHub repository. - **CLI installation is optional but recommended** – installing Claude Code or Codex CLI enables the `claude plugin` commands for managing individual plugins. - **Authentication and connectivity are mandatory** – you need internet access to fetch packages from GitHub and must be logged into your Claude account to execute CLI commands. - **Nine plugins available** – the marketplace includes 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. ## Frequently Asked Questions ### Do I need to install all nine plugins to use the PM Skills Marketplace? No. While adding the marketplace via Claude Cowork installs all nine plugins automatically, you can selectively install individual plugins using the CLI. Run `claude plugin install` followed by the specific plugin name (e.g., `pm-product-strategy@pm-skills`) to install only the capabilities you need, as documented in the repository's [`README.md`](https://github.com/phuryn/pm-skills/blob/main/README.md). ### Can I use the PM Skills Marketplace without installing the Claude Code CLI? Yes. The marketplace supports **Claude Cowork**, the web-based UI, which requires no local installation. Navigate to Customize → Browse plugins → Personal → +, then add the marketplace from GitHub using the repository name `phuryn/pm-skills` to access all skills immediately. ### What happens if I lose internet connectivity during plugin installation? The installation will fail. According to the source code in [`README.md`](https://github.com/phuryn/pm-skills/blob/main/README.md), internet connectivity is required to fetch plugin packages from GitHub during installation. The CLI pulls plugin definitions directly from the `phuryn/pm-skills` repository, so a stable connection is mandatory when running `claude plugin marketplace add` or installing individual plugins. ### Do I need a specific type of Claude account to use the marketplace? Yes. You need a valid Claude or Codex account, and you must be logged in before running CLI install steps. The CLI commands require authentication to the Claude service to function properly, as noted in the repository documentation.
