Build a Self-Aware Code Complexity Analyzer That Rates Your Own Shame Level

Create a tool that analyzes Python source code and assigns it a 'shame score' based on various code smell metrics, then generates brutally honest feedback about the developer's choices. The tool should parse code, detect anti-patterns, and deliver verdicts wrapped in passive-aggressive commentary. from typing import List, Dict, Tuple, Optional, Union, Any from abc import...
