Can You Use phuryn/pm-skills as a Library? A Complete Integration Guide

Yes, you can use phuryn/pm-skills as a reusable library by installing it via Claude Code, Claude Cowork, or Codex, or by copying the markdown skill files into any AI assistant that supports the SKILL.md format.

The phuryn/pm-skills repository functions as a modular library of product management frameworks, distributing reusable knowledge blocks through a plugin-based architecture. Unlike traditional compiled libraries, it delivers skills (markdown-driven prompt templates) and commands (CLI-style workflows) that integrate directly into AI-assisted development environments. This guide explains how to consume phuryn/pm-skills as a library across Claude, OpenCode, Gemini, and other compatible platforms.

Understanding the Library Architecture

Skills, Commands, and Plugins

The repository organizes content into three distinct layers that function as a modular library:

• Skills are self-contained markdown files (conventionally named SKILL.md) that contain complete prompt templates. Each skill file in paths like pm-product-discovery/skills/brainstorm-ideas-existing/SKILL.md defines a specific product management capability that models can load on demand.

• Commands are thin wrappers that chain multiple skills together into CLI-style workflows. Files like pm-execution/commands/write-prd.md orchestrate several execution-related skills to create comprehensive workflows.

• Plugins group related skills and commands into domain-specific packages (e.g., pm-product-discovery, pm-go-to-market). The pm-go-to-market/.claude-plugin/plugin.json file serves as the plugin manifest that tells Claude which assets belong together, functioning similarly to a package manifest in traditional package managers.

Installing phuryn/pm-skills as a Library

Claude Code CLI Integration

To use phuryn/pm-skills as a library in Claude Code, first add the marketplace to your environment, then install specific plugins:

# Add the marketplace (one-time setup)

claude plugin marketplace add phuryn/pm-skills

# Install only the product-discovery plugin

claude plugin install pm-product-discovery@pm-skills

After installation, invoke skills using slash commands:

/discover AI-powered meeting summarizer for remote teams

Claude Cowork GUI Setup

For Claude Cowork users, install the entire library through the graphical interface:

1. Open Customize → Browse plugins → Personal → +
2. Select Add marketplace from GitHub
3. Enter phuryn/pm-skills

This automatically installs all 9 plugins, making the same slash commands available through the UI.

OpenCode, Cursor, and Gemini Integration

Because the underlying assets are plain Markdown files, you can treat phuryn/pm-skills as a generic skill library in other AI assistants. Copy the skill folders into the appropriate directory for your tool:

# Copy skills for OpenCode (project-level)

for plugin in pm-*/; do
  mkdir -p .opencode/skills/
  cp -r "$plugin/skills/"* .opencode/skills/ 2>/dev/null
done

For Gemini, copy to ~/.gemini/skills/:

for plugin in pm-*/; do
  cp -r "$plugin/skills/"* ~/.gemini/skills/ 2>/dev/null
done

These skills work as pure markdown knowledge blocks; however, note that commands are Claude-specific and will not run in other assistants, while the skills themselves can be called by name from any compatible model.

Codex (OpenAI) Integration

Codex can consume the same marketplace definition used by Claude Code. The .claude-plugin/marketplace.json file at the repository root describes the available plugins:

codex plugin marketplace add phuryn/pm-skills
codex plugin add pm-go-to-market@pm-skills

Then invoke from your code:

response = codex.run("/plan-launch AI-code-review tool targeting mid-size engineering teams")
print(response)

Practical Usage Examples

Running a Complete Discovery Flow

Once installed via Claude Code, you can trigger complex product management workflows:

/discover AI-powered meeting summarizer for remote teams

This command leverages the pm-product-discovery plugin to execute a full discovery flow.

Copying Skills for Non-Claude Models

To use specific skills in OpenCode without installing the full plugin system:

# Copy specific skill folders

cp -r pm-product-discovery/skills/brainstorm-ideas-existing .opencode/skills/

Then invoke directly:

product-vision: Craft an inspiring vision for a new AI writing assistant.

Querying Risk Assumptions

After copying skills to a Gemini-compatible directory:

What are the riskiest assumptions for our AI-code-review tool?

The model references the copied SKILL.md files to provide structured analysis.

Repository Structure and Key Files

Understanding the file structure helps when using phuryn/pm-skills as a library:

• .claude-plugin/marketplace.json – The marketplace definition used by Claude Code and Codex to discover available plugins.

• pm-go-to-market/.claude-plugin/plugin.json – Plugin manifest that defines the skills and commands included in the go-to-market package.

• pm-product-discovery/skills/brainstorm-ideas-existing/SKILL.md – Representative skill file showing the markdown format used across the repository.

• pm-execution/commands/write-prd.md – Example command file that chains several execution-related skills into a single workflow.

• README.md – Contains the installation instructions for various platforms (lines 50-78).

• pm-toolkit/README.md – Documentation for a minimal plugin containing utilities like resume review and NDA drafting.

Summary

• phuryn/pm-skills is not a compiled library but a catalog of markdown-based skills and commands that function as reusable modules.

• Install via Claude Code using claude plugin marketplace add phuryn/pm-skills followed by specific plugin installation commands.

• Cross-platform compatibility allows you to copy SKILL.md files into OpenCode, Gemini, Cursor, or Kiro directories for use with any model supporting the format.

• Plain-text architecture enables version control, forking, and vending without binary dependencies.

• Plugin manifests in .claude-plugin/plugin.json files define modular groupings, allowing you to import only the domains you need.

Frequently Asked Questions

Is phuryn/pm-skills a traditional Python or npm library?

No, phuryn/pm-skills is not a compiled library distributed via PyPI or npm. It is a collection of Claude plugins containing markdown-based skills and commands. You consume it through AI assistant marketplaces or by copying the plain-text skill files into your project's skill directories.

Can I use these skills without Claude?

Yes, but with limitations. The skills (markdown files) are portable and work with any AI assistant that reads the SKILL.md format, including OpenCode, Gemini, Cursor, and Kiro. However, the commands (CLI-style workflows) are Claude-specific and will not execute in other environments.

How do I install only specific domains from the library?

Use the plugin-based installation to import only the modules you need. For example, in Claude Code run claude plugin install pm-toolkit@pm-skills to get only the toolkit utilities, or claude plugin install pm-execution@pm-skills for execution-related skills. This modular approach keeps your environment lightweight.

Where does the marketplace configuration reside?

The marketplace definition is stored in the root-level .claude-plugin/marketplace.json file, which Claude Code and Codex read to discover available plugins. Individual plugin configurations reside in their respective directories (e.g., pm-go-to-market/.claude-plugin/plugin.json), defining which skills and commands each package exports.
