## Quick Start
### Using Prompts
1. **Browse** the [prompts directory](prompts/) or [web interface](https://aj-geddes.github.io/useful-ai-prompts/)
2. **Copy** the prompt content
3. **Paste** into ChatGPT, Claude, or your preferred AI assistant
4. **Customize** the `{{variables}}` with your specific context
### Using Claude Code Skills
```bash
# 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
```
### Using Automation Hooks
```bash
# 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
```
