Installation

Option 1: Interactive installer (recommended)

Use the @supercorks/skills-installer CLI to interactively select and install skills:

Installer repository: supercorks/agent-skills-installer

npx @supercorks/skills-installer

If you run into issues with npx resolving the executable, use the explicit form:

npx --package=@supercorks/skills-installer skills-installer install

This will:

1. Let you choose the installation path (.github/skills/ (Copilot), ~/.codex/skills/ (Codex), .claude/skills/ (Claude), or custom)
2. Optionally add the path to .gitignore
3. Let you select which skills to install via checkboxes
4. Sparse-clone only the selected skills

Option 2: Clone specific skills manually

Use Git sparse-checkout to clone only the skills you need:

# Clone the repo without checking out files
git clone --filter=blob:none --sparse https://github.com/supercorks/agent-skills.git .github/skills
cd .github/skills

# Checkout only the skills you need
git sparse-checkout set address-pr-comments boulevard describe-image gtm-manager

Option 3: Copy skills to your project

Copy the skill folder to your project's .github/skills/ directory:

# From a cloned agent-skills repo
cp -r address-pr-comments /path/to/your/project/.github/skills/

Updating Skills

If you installed using sparse-checkout (Option 1 or 2):

cd .github/skills  # or wherever you installed
git pull

Skill Structure

Each skill follows this structure:

skill-name/

Adding Skills to Your Project

1. Install skills to .github/skills/ (or .claude/skills/ for Claude)
2. The AI agent will automatically discover and use skills from this location
3. Each skill's SKILL.md contains the instructions the AI follows
