• Long Methods (> 50 lines)
• Large Classes (> 500 lines or > 10 public methods)
• Long Parameter Lists (> 4 parameters)
• Feature Envy, Data Clumps

2. Complexity Indicators

• Deep Nesting (> 3 levels)
• Cyclomatic Complexity (> 10 branches)
• God Objects
• Circular Dependencies

3. Duplication

• Copy-Paste Code
• Parallel Hierarchies
• Repeated Conditionals

4. Outdated Patterns

• Deprecated APIs
• Legacy Patterns
• Dead Code
