+# Enhanced Code Analysis Module
+
+This module provides comprehensive code analysis capabilities for Python codebases, focusing on detailed error detection, function call analysis, and type validation.
+
+## Features
+
+### Error Detection
+
+The error detection system identifies various issues in your code:
+
+- **Parameter Validation**: Detects unused parameters, parameter count mismatches, and missing required parameters
+- **Call Validation**: Validates function call-in and call-out points, detects circular dependencies
+- **Return Validation**: Checks for inconsistent return types and values
+- **Code Quality**: Identifies unreachable code, overly complex functions, and potential exceptions
+
+### Function Call Analysis
+
+The function call analysis provides insights into how functions interact:
+
+- **Call Graph**: Builds a graph of function calls to visualize dependencies
+- **Parameter Usage**: Analyzes how parameters are used within functions
+- **Call Statistics**: Identifies most called functions, entry points, and leaf functions
+- **Call Chains**: Finds paths between functions and calculates call depths
+
+### Type Validation
+
+The type validation system checks for type-related issues:
+
+- **Type Annotations**: Validates type annotations and identifies missing annotations
+- **Type Compatibility**: Checks for type mismatches and inconsistencies
+- **Type Inference**: Infers types for variables and expressions where possible
+
+## Usage
+
+### Using the CodeAnalyzer
+
+```python
+from codegen import Codebase
+from codegen_on_oss.analysis.analysis import CodeAnalyzer
+
+# Create a codebase from a repository
+codebase = Codebase.from_repo("owner/repo")
+
+# Create an analyzer
+analyzer = CodeAnalyzer(codebase)
+
+# Get comprehensive analysis
+results = analyzer.analyze_all()
+
+# Access specific analysis components
+error_analysis = analyzer.analyze_errors()
+function_call_analysis = analyzer.analyze_function_calls()
+type_analysis = analyzer.analyze_types()
+complexity_analysis = analyzer.analyze_complexity()
+import_analysis = analyzer.analyze_imports()
+
+# Get detailed information about specific elements
+function = analyzer.find_function_by_name("my_function")
+call_graph = analyzer.get_function_call_graph()
+callers = call_graph.get_callers("my_function")
+callees = call_graph.get_callees("my_function")
+```
+
+### Using the API
+
+The module provides a FastAPI-based API for analyzing codebases:
+
+- `POST /analyze_repo`: Analyze an entire repository
+- `POST /analyze_file`: Analyze a specific file
+- `POST /analyze_function`: Analyze a specific function
+- `POST /analyze_errors`: Get detailed error analysis with optional filtering
+
+Example request to analyze a repository:
+
+```json
+{
+ "repo_url": "owner/repo"
+}
+```
+
+Example request to analyze a specific function:
+
+```json
+{
+ "repo_url": "owner/repo",
+ "function_name": "my_function"
+}
+```
+
+## Error Categories
+
+The error detection system identifies the following categories of errors:
+
+- `PARAMETER_TYPE_MISMATCH`: Parameter type doesn't match expected type
+- `PARAMETER_COUNT_MISMATCH`: Wrong number of parameters in function call
+- `UNUSED_PARAMETER`: Parameter is declared but never used
+- `UNDEFINED_PARAMETER`: Parameter is used but not declared
+- `MISSING_REQUIRED_PARAMETER`: Required parameter is missing in function call
+- `RETURN_TYPE_MISMATCH`: Return value type doesn't match declared return type
+- `UNDEFINED_VARIABLE`: Variable is used but not defined
+- `UNUSED_IMPORT`: Import is never used
+- `UNUSED_VARIABLE`: Variable is defined but never used
+- `POTENTIAL_EXCEPTION`: Function might throw an exception without proper handling
+- `CALL_POINT_ERROR`: Error in function call-in or call-out point
+- `CIRCULAR_DEPENDENCY`: Circular dependency between functions
+- `INCONSISTENT_RETURN`: Inconsistent return statements in function
+- `UNREACHABLE_CODE`: Code that will never be executed
+- `COMPLEX_FUNCTION`: Function with high cyclomatic complexity
+
+## Extending the Analysis
+
+You can extend the analysis capabilities by:
+
+1. Creating new detector classes that inherit from `ErrorDetector`
+2. Implementing custom analysis logic in the `detect_errors` method
+3. Adding the new detector to the `CodeAnalysisError` class
+
+Example:
+
+```python
+from codegen_on_oss.analysis.error_detection import ErrorDetector, ErrorCategory, ErrorSeverity, CodeError
+
+class MyCustomDetector(ErrorDetector):
+ def detect_errors(self) -> List[CodeError]:
+ self.clear_errors()
+
+ # Implement custom detection logic
+ for function in self.codebase.functions:
+ # Check for issues
+ if some_condition:
+ self.errors.append(CodeError(
+ category=ErrorCategory.COMPLEX_FUNCTION,
+ severity=ErrorSeverity.WARNING,
+ message="Custom error message",
+ file_path=function.filepath,
+ function_name=function.name
+ ))
+
+ return self.errors
+```
+
+## Future Enhancements
+
+Planned enhancements for the analysis module:
+
+- Integration with external linters and type checkers
+- Machine learning-based error detection
+- Interactive visualization of analysis results
+- Performance optimization for large codebases
+- Support for more programming languages
