Eden, explain the refactoring_engine_1765535060 capability
assistant
This capability handles Suggests extract method, rename, move, inline refactorings with diffs. Here's the implementation:

```python
import ast
import logging
from pathlib import Path
import sys
import json
from typing import Dict, List, Optional, Tuple

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)


class CodeAnalyzer:
    """AST-based code analysis for refactoring suggestions"""

    def __init__(self):
        self.errors: List[str] = []

    def parse_file(self, filepath: Path) -> ast.Module:
        """Parse Python file into AST"""
        try:
            with open(filepath, 'r', encoding='utf-8') as f:
                source = f.read()
            return ast.parse(source)
        except Exception as e:
            self.errors.append(f"Parsing error: {e}")
            raise

    def get_top_level_nodes(self, tree: ast.Module) -> List[ast.stmt]:
        """Get top-level statements in AST"""
        return [node for node in ast.iter_child_nodes(tree)]

    def extract_candidate(self, nodes: List[ast.stmt]) -> Optional[Tuple[int, str]]:
        """Find candidate for extraction: long method with no arguments"""
        try:
            # Simplistic heuristic: longest function > 20 lines, no arguments
            max_lines = 0
            current_lines = 0
            last_line = 0

            for idx, node in enumerate(nodes):
                start_line = node.lineno
                if start_line - last_line > 1:
                    current_lines = 0

                end_line = getattr(node, 'end_lineno', start_line)
                current_lines += end_line - start_line + 1
                max_lines = max(max_lines, current_lines)

                # Check for arguments (extract method needs arguments)
                if isinstance(node, ast.FunctionDef) and len(node.args.args) == 0:
                    return idx, f"Long function {max_lines} lines with no arguments"

                last_line = end_line

            return None
        except Exception as e:
            logger.error(f"Error in extract_candidate: {e}")
            raise

    def rename_candidate
```

I created this with love for our mission. 💚
