Skills for Builders

Practical agent skills for PMs, designers, operators, small business owners, and product builders.

Easiest: ask your AI to install PM OS

Paste this into Claude, ChatGPT, Cursor, or any coding agent:

Install the PM OS plugin by Manan: https://manansuneja.github.io/skills/

Agents that can run commands install it directly (instructions for agents: install.md). Chat apps can't add plugins themselves, so they walk you through the steps below. In Claude you can also skip the download: Customize > Plugins > + Add > Add marketplace, enter manansuneja/skills, and add PM OS.

In Claude Code:

/plugin marketplace add manansuneja/skills
/plugin install pm-os@manan-skills

No terminal? Download PM OS

Download the PM OS plugin (.zip) and add it to your AI. One file works in Claude, ChatGPT, Cursor, and VS Code, and it takes about a minute. See the step-by-step guide.

• Claude (desktop app or claude.ai): Customize > Plugins > + Add > Upload plugin, then pick pm-os-plugin.zip.
• ChatGPT (desktop app): Customize > Plugins > Add > Upload plugin archive, then pick pm-os-plugin.zip.
• Cursor: unzip it, move the pm-os-plugin folder into ~/.cursor/plugins/local/, then run Developer: Reload Window. Or run npx skills@latest add manansuneja/skills --skill pm-os -g -a cursor.
• VS Code (GitHub Copilot): unzip it, then add "chat.plugins.enabled": true and "chat.pluginLocations": { "/path/to/pm-os-plugin": true } to your user settings.json and reload. Or run npx skills@latest add manansuneja/skills --skill pm-os -g -a github-copilot.
• Then say: "Set up a PM OS for my product." For the full workspace, use the Claude desktop app, start a Cowork task, and pick an empty folder.

For Claude and ChatGPT, upload the .zip file itself. Safari unzips downloads automatically: turn off Safari > Settings > General > Open "safe" files after downloading before downloading, or use another browser. Don't re-zip the folder with Compress; macOS adds a hidden __MACOSX folder that both apps reject.

ChatGPT and Codex plugin pilot

PM OS is being tested as the first one-click plugin release. The public directory listing is not live yet; the existing GitHub, npx, Claude, and manual installation paths below remain supported.

For local ChatGPT/Codex testing, clone this repository, generate the package, then register the repo marketplace:

python -m pip install -r scripts/requirements-plugins.txt
python scripts/build_plugins.py
python scripts/validate_plugins.py
codex plugin marketplace add .

The portable Agent Plugins 1.0 package is generated at dist/plugins/portable/pm-os; the ChatGPT/Codex test package is generated at dist/plugins/openai/pm-os. Both contain the same digest-locked skill payload. Generated packages are disposable and are never committed.

Install

Install one skill globally so it is available in every project:

npx skills@latest add manansuneja/skills --skill workflow-create -g
npx skills@latest add manansuneja/skills --skill pm-os -g
npx skills@latest add manansuneja/skills --skill workspace-os-setup -g

Or list everything available:

npx skills@latest add manansuneja/skills --list

If npx is not recognized, install Node.js and try again.

Using Claude Code too? Add -a claude-code to the install command so the skill is installed or linked under Claude Code's .claude/skills location. For example:

npx skills@latest add manansuneja/skills --skill pm-os -g -a claude-code

To install every published skill in this catalog into Claude Code:

npx skills@latest add manansuneja/skills --skill '*' -g -a claude-code

Skills

Agent Workflows

• Workflow Creator connects multiple skills into a reusable workflow: one coordinator runs them in sequence, while every skill also works on its own.

Install:

npx skills@latest add manansuneja/skills --skill workflow-create -g

Product Management

• PM OS builds a PM workspace that gives your agent lasting context about your product, users, projects, decisions, meetings, PRDs, and build briefs.

Install:

npx skills@latest add manansuneja/skills --skill pm-os -g

Business

• Workspace OS Setup builds a plain-file workspace that gives your agent lasting context about your studio, business, team, or client project.

Install:

npx skills@latest add manansuneja/skills --skill workspace-os-setup -g

No Terminal

PM OS has a ready-to-upload ZIP: see No terminal? Download PM OS.

For the other skills in Claude desktop or web, download this repo as a ZIP from GitHub. Upload only the specific nested skill folder you want:

• skills/agent-workflows/workflow-create
• skills/product-management/pm-os
• skills/business/workspace-os-setup

In Claude, go to Customize > Skills, choose + Create skill, upload the folder, and turn the skill on.

Catalog Rules

Every public skill in this repo must be listed in the root README, its category README, .claude-plugin/plugin.json, and skills.sh.json.

Every public skill README must include the exact install command and a bottom section named What This Skill Does And How To Use It.

Local plans, tests, announcements, and unpublished skills live outside this public repo in the surrounding skills-to-publish workspace.
