+# Code Analysis Module with Error Context
+
+This module provides robust and dynamic code analysis capabilities with a focus on error detection and contextual error information.
+
+## Overview
+
+The code analysis module consists of several components:
+
+1. **CodeAnalyzer**: The main class that integrates all analysis components and provides a unified interface.
+2. **ErrorContextAnalyzer**: A specialized class for detecting and analyzing errors in code.
+3. **CodeError**: A class representing an error in code with detailed context information.
+4. **API Endpoints**: FastAPI endpoints for accessing the analysis functionality.
+
+## Features
+
+### Code Structure Analysis
+
+- Analyze codebase structure and dependencies
+- Generate dependency graphs for files and symbols
+- Analyze import relationships and detect circular imports
+- Get detailed information about files, functions, classes, and symbols
+
+### Error Detection and Analysis
+
+- Detect syntax errors, type errors, parameter errors, and more
+- Analyze function parameters and return statements for errors
+- Detect undefined variables and unused imports
+- Find circular dependencies between symbols
+- Provide detailed context information for errors
+
+### API Endpoints
+
+- `/analyze_repo`: Analyze a repository and return various metrics
+- `/analyze_symbol`: Analyze a symbol and return detailed information
+- `/analyze_file`: Analyze a file and return detailed information
+- `/analyze_function`: Analyze a function and return detailed information
+- `/analyze_errors`: Analyze errors in a repository, file, or function
+
+## Error Types
+
+The module can detect the following types of errors:
+
+- **Syntax Errors**: Invalid syntax in code
+- **Type Errors**: Type mismatches in expressions
+- **Parameter Errors**: Incorrect function parameters
+- **Call Errors**: Incorrect function calls
+- **Undefined Variables**: Variables used without being defined
+- **Unused Imports**: Imports that are not used in the code
+- **Circular Imports**: Circular dependencies between files
+- **Circular Dependencies**: Circular dependencies between symbols
+- **Name Errors**: References to undefined names
+- **Import Errors**: Problems with import statements
+- **Attribute Errors**: References to undefined attributes
+
+## Error Severity Levels
+
+The module assigns severity levels to each error:
+
+- **Critical**: Errors that will definitely cause the code to crash or fail
+- **High**: Errors that are likely to cause problems in most execution paths
+- **Medium**: Errors that may cause problems in some execution paths
+- **Low**: Minor issues that are unlikely to cause problems but should be fixed
+- **Info**: Informational messages about potential improvements
+
+## 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)
+
+# Analyze errors in the codebase
+errors = analyzer.analyze_errors()
+
+# Get detailed error context for a function
+function_errors = analyzer.get_function_error_context("function_name")
+
+# Get detailed error context for a file
+file_errors = analyzer.get_file_error_context("path/to/file.py")
+```
+
+### Using the API
+
+```bash
+# Analyze a repository
+curl -X POST "http://localhost:8000/analyze_repo" \
+     -H "Content-Type: application/json" \
+     -d '{"repo_url": "owner/repo"}'
+
+# Analyze errors in a function
+curl -X POST "http://localhost:8000/analyze_function" \
+     -H "Content-Type: application/json" \
+     -d '{"repo_url": "owner/repo", "function_name": "function_name"}'
+
+# Analyze errors in a file
+curl -X POST "http://localhost:8000/analyze_file" \
+     -H "Content-Type: application/json" \
+     -d '{"repo_url": "owner/repo", "file_path": "path/to/file.py"}'
+```
+
+## Error Context Example
+
+Here's an example of the error context information provided for a function:
+
+```json
+{
+  "function_name": "calculate_total",
+  "file_path": "app/utils.py",
+  "errors": [
+    {
+      "error_type": "parameter_error",
+      "message": "Function 'calculate_discount' called with 1 arguments but expects 2",
+      "line_number": 15,
+      "severity": "high",
+      "context_lines": {
+        "13": "def calculate_total(items):",
+        "14": "    total = sum(item.price for item in items)",
+        "15": "    discount = calculate_discount(total)",
+        "16": "    return total - discount",
+        "17": ""
+      },
+      "suggested_fix": "Update call to provide 2 arguments: calculate_discount(total, discount_percent)"
+    }
+  ],
+  "callers": [
+    {"name": "process_order"}
+  ],
+  "callees": [
+    {"name": "calculate_discount"}
+  ],
+  "parameters": [
+    {
+      "name": "items",
+      "type": "List[Item]",
+      "default": null
+    }
+  ],
+  "return_info": {
+    "type": "float",
+    "statements": ["total - discount"]
+  }
+}
+```
+
+## Implementation Details
+
+### ErrorContextAnalyzer
+
+The `ErrorContextAnalyzer` class is responsible for detecting and analyzing errors in code. It uses various techniques to detect errors, including:
+
+- **AST Analysis**: Parsing the code into an abstract syntax tree to detect syntax errors and undefined variables
+- **Graph Analysis**: Building dependency graphs to detect circular imports and dependencies
+- **Pattern Matching**: Using regular expressions to detect potential type errors and other issues
+- **Static Analysis**: Analyzing function parameters, return statements, and variable usage
+
+### CodeError
+
+The `CodeError` class represents an error in code with detailed context information. It includes:
+
+- **Error Type**: The type of error (syntax, type, parameter, etc.)
+- **Message**: A descriptive message explaining the error
+- **Location**: The file path and line number where the error occurs
+- **Severity**: The severity of the error (critical, high, medium, low, info)
+- **Context Lines**: The lines of code surrounding the error
+- **Suggested Fix**: A suggested fix for the error
+
+## Running the API Server
+
+To run the API server locally:
+
+```bash
+cd codegen-on-oss
+python -m codegen_on_oss.analysis.analysis
+```
+
+The server will be available at `http://localhost:8000`.
