| Metric | Description |
|---|---|
| Cyclomatic Complexity | McCabe's complexity — number of independent paths through code |
| Lines of Code | Non-blank, non-comment lines |
| Max Nesting Depth | Deepest level of nested control structures |
| Function Count | Number of functions/methods |
| Score | Rating | Meaning |
|---|---|---|
| 1-5 | Low | Simple, easy to maintain |
| 6-10 | Moderate | Manageable complexity |
| 11-20 | High | Consider refactoring |
| 21+ | Very High | Refactoring strongly recommended |
