Installation

GTM Skills can be installed using two methods: the skills.sh CLI or the Claude Code plugin manager. Both methods install the skills to ~/.claude/skills/, making them globally available across all your projects.

​
Prerequisites

Before installing GTM Skills, ensure you have:
  • Claude Code: Installed and running on your system
  • Node.js: Required for the skills.sh CLI method (if using that approach)
  • Extruct API Token: Sign up at extruct.ai to get a free trial token

​
Method 1: skills.sh CLI

The skills.sh CLI is a command-line tool for managing Claude Code skills. This is the recommended method if you’re comfortable with terminal commands.

​
Installation Steps

1

Run the installation command

Open your terminal and run:
npx skills add extruct-ai/gtm-skills
This command uses npx to run the skills CLI without requiring a global installation.
2

Verify installation

The skills will be installed to ~/.claude/skills/gtm-skills/. You can verify by checking:
ls ~/.claude/skills/
You should see gtm-skills in the output.
3

Configure environment

Set your Extruct API token as an environment variable:
export EXTRUCT_API_TOKEN="your_token_here"
Add this to your shell configuration file (~/.bashrc, ~/.zshrc, etc.) to persist across sessions.
The skills.sh CLI is maintained by Vercel Labs. You can find the source code at github.com/vercel-labs/skills.

​
Method 2: Claude Code Plugin Manager

The Claude Code plugin manager provides an in-chat interface for installing skills. This method is ideal if you prefer working directly within Claude Code.

​
Installation Steps

1

Add the marketplace

In Claude Code, run:
/plugin marketplace add extruct-ai/gtm-skills
This adds the GTM Skills marketplace to your available plugins.
2

Install the plugin

Next, install the skills:
/plugin install gtm-skills
Claude will download and install all skill templates to ~/.claude/skills/.
3

Configure your API token

Set your Extruct API token:
export EXTRUCT_API_TOKEN="your_token_here"
You can do this in your terminal or add it to your shell configuration file.
Plugin manager commands work directly in Claude Code chat. No need to switch to a terminal.

​
Where Skills Are Stored

Once installed, skills are stored in: 
~/.claude/skills/gtm-skills/
This location makes them globally available across all your projects. You install once and can use the skills in any project directory.

​
Skill Structure

The installed skills directory contains: 
gtm-skills/
├── .claude-plugin/
│   ├── plugin.json
│   └── marketplace.json
└── skills/
    ├── context-building/
    ├── hypothesis-building/
    ├── list-building/
    ├── market-research/
    ├── enrichment-design/
    ├── list-enrichment/
    ├── table-creation/
    ├── list-segmentation/
    ├── people-search/
    ├── email-search/
    ├── email-prompt-building/
    ├── email-generation/
    ├── email-response-simulation/
    └── campaign-sending/
Each skill directory contains:
  • SKILL.md - The skill template with instructions for Claude
  • references/ - Supporting documentation and API references (where applicable)

​
Environment Variables

GTM Skills uses environment variables to authenticate with various services. Only the Extruct API token needs to be set upfront. Other credentials are requested in-chat when the corresponding skill runs.

​
Required: Extruct API Token

Set your Extruct API token before using GTM Skills: 
export EXTRUCT_API_TOKEN="your_token_here"
Get a free trial token with 100 credits at extruct.ai. No credit card required.

​
Optional: Additional Integrations

Depending on which skills you use, you may need additional API credentials:
VariableServiceUsed by
EXTRUCT_API_TOKENExtruct APIlist-building, list-enrichment, table-creation, people-search, list-segmentation, email-search
Other credentialsEmail enrichment, Campaign sendingRequested in-chat when needed
You don’t need to set all credentials upfront. Claude will ask for them when you use skills that require additional integrations.

​
Verifying Installation

To verify that GTM Skills is installed correctly:
1

Check the skills directory

ls ~/.claude/skills/gtm-skills/skills/
You should see 14 skill directories.
2

Verify environment variable

echo $EXTRUCT_API_TOKEN
This should output your API token.
3

Test with a prompt

In Claude Code, try a simple prompt:
I'm building www.example.com.
Read my website, figure out my ICP,
and draft a plan for an outbound campaign.
If installation was successful, Claude will begin researching and planning your campaign.

​
Troubleshooting

​
Skills Not Found

If Claude doesn’t recognize GTM Skills:
  1. Verify the installation directory exists: ls ~/.claude/skills/gtm-skills/
  2. Restart Claude Code to reload the skills registry
  3. Try reinstalling using one of the methods above

​
API Token Issues

If you see authentication errors:
  1. Verify your token is set: echo $EXTRUCT_API_TOKEN
  2. Check that the token is valid at extruct.ai
  3. Make sure the environment variable is available in your Claude Code session
  4. Restart your terminal/Claude Code after setting the variable

​
Permission Errors

If you encounter permission issues during installation:
  1. Ensure you have write permissions to ~/.claude/
  2. Try running without sudo - skills should install to your user directory
  3. Check that Node.js/npx is properly installed (for skills.sh method)
