GitHub Cloner - Repository Skill Generator

A Claude Code skill that analyzes any GitHub repository and generates a custom development skill tailored to that project's patterns, conventions, and documentation.

What It Does

GitHub Cloner examines a repository and extracts:

• Contributor patterns - Who are the key developers? What areas do they focus on?
• Commit conventions - Do they use conventional commits? What prefixes are common?
• PR patterns - How are PRs titled and described? What's typical scope?
• Issue organization - What labels are used? Are there templates?
• Documentation - README, CONTRIBUTING, CLAUDE.md, wiki content

It then generates a skill file that helps any AI assistant work "in tune" with that repository's actual development patterns.

Installation

Copy the skill to your Claude Code skills directory:

# Clone this repo
git clone https://github.com/esaruoho/github-cloner.git

# Copy to Claude Code skills directory
cp -r github-cloner ~/.claude/skills/

Or manually copy the files to ~/.claude/skills/github-cloner/.

Usage

/github-cloner <repository>

Examples:

/github-cloner https://github.com/anthropics/claude-code
/github-cloner facebook/react
/github-cloner owner/repo

Requirements

• Claude Code CLI
• GitHub CLI (gh) installed and authenticated

# Install GitHub CLI
brew install gh

# Authenticate
gh auth login

Output

After running, a new skill is created at ~/.claude/skills/<repo-name>/ containing:

File	Purpose
SKILL.md	Human-readable skill with conventions, patterns, instructions
analysis.json	Machine-readable structured data (for other LLMs)

Features

• Interactive options - Choose full clone vs API-only, commit history timeframe
• Machine-readable output - analysis.json follows a JSON schema for LLM interoperability
• Cross-LLM compatible - Other AI assistants can consume the structured data
• Incremental updates - Re-run to refresh with latest commits/PRs

Documentation

File	Description
SKILL.md	The skill instructions (what Claude follows)
AGENT-PROTOCOL.md	How other LLMs can consume the output
INTEGRATION-GUIDE.md	Building repository-specific skills
WORKFLOW-GUIDE.md	Step-by-step usage workflow
schemas/repo-analysis-schema.json	JSON schema for analysis.json

Example Workflow

1. Generate a skill from any repo:

   cd ~/repos/my-project
   claude
   # In Claude: /github-cloner owner/my-project

2. Use the skill from anywhere:

   cd ~/dev/my-project-work
   claude
   # The skill is automatically available!

3. Update when needed:

   /github-cloner owner/my-project

Use Cases

• Onboard to a new codebase - Quickly understand conventions and key contributors
• Cross-LLM workflows - Generate data for Claude, use it with GPT/Gemini
• Build custom skills - Use as a foundation for repository-specific skills
• Team documentation - Auto-generate development guides from actual patterns
