🔍 Finding the Right Pattern

Quick Decision Tree

1. What are you building?

   • Web app → Start with Architecture
   • CLI tool → Start with CLAUDE.md
   • Service → Start with Deployment

2. What’s your main concern?

   • Quality → Testing Patterns
   • Speed → Performance Patterns
   • Security → Security Patterns
   • Process → Workflow Patterns

3. What’s your scale?

   • Small project → Basic patterns in each category
   • Team project → Add Collaboration Patterns
   • Enterprise → Add Project Management

💡 Pattern Principles

Core Principles

1. Simplicity First - Start simple, evolve as needed
2. Testability - All patterns should enhance testability
3. Maintainability - Patterns should reduce maintenance burden
4. Performance - Consider performance implications
5. Security - Security should be built-in, not bolted-on

Anti-Patterns to Avoid

• Over-engineering simple solutions
• Copying patterns without understanding
• Ignoring team conventions
• Premature optimization
• Security as an afterthought
