How to Install AI Skills on Claude Code: Step-by-Step Tutorial

Before you start, make sure you have:

• Claude Code installed on your computer (the terminal-based version from Anthropic)
• Node.js version 18 or newer (Claude Code requires this anyway)
• A terminal or command prompt

That's it. No other tools, accounts, or configuration needed for free skills.

Open your terminal and run this single command:

claude mcp add agentpowers -- npx -y @agentpowers/mcp-server

This tells Claude Code to connect to the AgentPowers marketplace. It only takes a few seconds, and you only need to do it once.

To verify it worked, run:

claude mcp list

You should see agentpowers in the list.

Now start Claude Code normally and ask it to search for skills:

"Search AgentPowers for code review skills"

Claude will query the marketplace and show you matching results with names, descriptions, prices, and security ratings.

You can also browse the marketplace directly at agentpowers.ai/skills.

Once you've found a skill you want, simply tell Claude:

"Install the code-review-pro skill from AgentPowers"

For free skills, installation happens immediately. For paid skills, Claude will open a checkout page in your browser. After payment, the skill installs automatically.

The skill is available in your very next message. No restart needed.

After installation, just ask Claude to use the skill naturally:

"Review the authentication module for security issues"

Claude now has the specialized knowledge from the skill. It will follow the skill's methodology, check for the right things, and produce structured output.

The skill stays installed permanently. You can use it in any future Claude Code session.

Ask Claude to check what you have installed:

"What AgentPowers skills do I have installed?"

To check for updates:

"Check if any of my AgentPowers skills have updates"

To uninstall a skill:

"Uninstall the code-review-pro skill"
