How to Fork the coreyhaines31/marketingskills Repository: A Complete Guide

Fork the repository via GitHub's interface, clone your copy locally, optionally add the upstream remote for synchronization, then customize markdown skills in skills/ and validate changes with validate-skills.sh before committing.

The coreyhaines31/marketingskills repository hosts a curated collection of AI Agent Skills designed for marketing-focused automation tasks. Because the architecture relies on plain markdown files and zero-dependency CLI tools rather than compiled binaries, forking the repository creates a lightweight sandbox where you can tailor skill definitions to your brand without managing complex build steps or hidden runtime configurations.

Repository Architecture Overview

The repository follows a content-driven architecture that makes forking safe and straightforward. All skill definitions live as markdown files with standardized front-matter, while helper tools are written as zero-dependency Node.js scripts that execute without additional packages.

Key structural components include:

• skills/ – Contains subdirectories for each skill (e.g., skills/copywriting/), each holding a SKILL.md file that follows the Agent Skills specification with metadata, trigger phrases, and instructions.
• tools/clis/ – Houses zero-dependency Node.js CLIs (such as tools/clis/*.js) that agents invoke to interact with third-party marketing platforms like Stripe or Zapier.
• .github/workflows/validate-skill.yml – GitHub Actions workflow that validates skill front-matter and enforces naming conventions on every push.
• validate-skills.sh – Local shell script that runs the same linting checks as the CI pipeline.
• AGENTS.md – Governance document defining naming rules, linting standards, and publishing conventions for agent consumers.
• VERSIONS.md – Central registry tracking published skill versions, enabling agents to warn users about outdated implementations.
• tools/REGISTRY.md – Index of available CLI tools and their corresponding marketing service integrations.

Step-by-Step Forking Instructions

Create Your Fork on GitHub

Navigate to https://github.com/coreyhaines31/marketingskills and click the Fork button in the upper-right corner. This creates a complete copy of the repository under your GitHub username while preserving the full commit history and branch structure.

Clone and Configure Remotes

After forking, clone your copy to your local machine and configure the original repository as an upstream remote to facilitate future synchronization:

# Clone your fork

git clone https://github.com/<YOUR_USERNAME>/marketingskills.git
cd marketingskills

# Add the original repository as upstream

git remote add upstream https://github.com/coreyhaines31/marketingskills.git
git fetch upstream

Customize Skills and Validate

Because skills are pure markdown, you can immediately edit any file without recompilation. For example, to customize the copywriting skill:

# Edit the skill definition

code skills/copywriting/SKILL.md

# Validate your changes locally

bash validate-skills.sh

The validate-skills.sh script (and validate-skills-official.sh for stricter checks) parses the YAML front-matter in each SKILL.md file to ensure metadata compliance before you push.

Push Changes and Sync with Upstream

Commit your customizations and push them to your fork:

git add skills/copywriting/SKILL.md
git commit -m "feat: customize copywriting skill for brand voice"
git push origin main

To incorporate updates from the original repository, periodically run:

git fetch upstream
git checkout main
git merge upstream/main

Working with Forked Skills

Editing Skill Definitions

Each skill resides in skills/<skill-name>/SKILL.md and follows a standardized format with front-matter metadata (title, description, version) followed by markdown content. Because these are text files, you can version-control your branding changes, prompt adjustments, and trigger phrase modifications using standard Git workflows.

Running Local Validation

Before pushing changes, execute the repository's validation tooling to catch front-matter violations or naming convention errors:

# Run the standard validation script

bash validate-skills.sh

# Or run the official strict validation

bash validate-skills-official.sh

These scripts mirror the checks performed by the .github/workflows/validate-skill.yml GitHub Actions workflow, ensuring your fork remains compatible with agent consumption standards.

Installing Skills from Your Fork

Once you have customized skills in your fork, you can install them using the skills CLI by referencing your namespace:

npx skills add <YOUR_USERNAME>/marketingskills --skill copywriting

If you create new integrations in tools/clis/custom-api.js, invoke them from within skill definitions using standard Node.js execution:

node tools/clis/custom-api.js --dry-run

The zero-dependency design means these scripts require only Node.js 18+ without additional package installations.

Summary

• Fork via GitHub's interface to create your own copy of the coreyhaines31/marketingskills repository under your username.
• Clone locally and add an upstream remote to synchronize with the original repository and receive updates.
• Customize markdown skills in skills/<skill-name>/SKILL.md files without build steps or compilation.
• Validate changes using validate-skills.sh to ensure front-matter compliance before committing.
• Leverage zero-dependency tools in tools/clis/ for marketing API integrations that run with system Node.js.

Frequently Asked Questions

Do I need Node.js or build tools to fork and customize this repository?

No. You can fork, clone, and edit the markdown-based skill definitions using only a text editor and Git. Node.js is only required if you intend to run the optional CLI tools in tools/clis/ or execute the validation scripts, which function with Node.js 18+ and carry no external dependencies.

How do I keep my fork synchronized with the original coreyhaines31/marketingskills repository?

Add the original repository as an upstream remote using git remote add upstream https://github.com/coreyhaines31/marketingskills.git, then periodically fetch and merge changes with git fetch upstream && git merge upstream/main. This workflow pulls in new skills, bug fixes, and version updates while preserving your local customizations.

What validation runs automatically when I push changes to my fork?

The GitHub Actions workflow defined in .github/workflows/validate-skill.yml automatically executes on every push and pull request, linting all SKILL.md files for correct front-matter syntax and enforcing naming conventions. This ensures your fork remains compatible with agent consumption standards even after customization.

Can I add new marketing API integrations to my fork?

Yes. Create new zero-dependency Node.js scripts in the tools/clis/ directory following the patterns established for existing integrations, then document them in tools/REGISTRY.md. Because the architecture requires no compiled binaries, you can extend the toolkit with additional marketing platform support while maintaining the repository's lightweight, fork-friendly structure.
