The largest open-source collection of production-ready AI prompts, Claude Code skills, and automation hooks for professionals.

Transform ChatGPT, Claude, and other AI assistants into expert consultants with 820+ curated resources spanning software development, business strategy, creative work, and emerging technologies.

Total: 120,000+ lines of production-ready guidance, code examples, and best practices.

1. Browse the prompts directory or web interface
2. Copy the prompt content
3. Paste into ChatGPT, Claude, or your preferred AI assistant
4. Customize the {{variables}} with your specific context

# Copy skills to your project
cp -r skills/ /path/to/your/project/.claude/skills/

# Skills auto-trigger based on your requests
# Example: "Help me refactor this legacy code"
# Claude Code automatically applies the refactor-legacy-code skill

# Copy hooks to your Claude Code configuration
cp -r hooks/ ~/.claude/hooks/

# Hooks run automatically on events like:
# - Pre-commit: security scanning, linting
# - Session setup: environment configuration
# - Test runner: automated test execution

Skills are specialized capabilities that Claude Code invokes automatically based on your requests.

Unlike prompts, skills:

• Auto-trigger when Claude Code detects relevant keywords
• Provide step-by-step guidance with multi-language code examples
• Include industry best practices and production patterns
• Range from 200-500+ lines of detailed instructions

See SKILLS-MATRIX.md for the complete reference with trigger keywords.

Hooks execute automatically in response to Claude Code events.

See HOOKS-LIBRARY.md for installation and configuration.
