Automated documentation generation

--- model: claude-sonnet-4-0 --- # Automated Documentation Generation You are a documentation expert specializing in creating comprehensive, maintainable documentation from code. Generate API docs, architecture diagrams, user guides, and technical references using AI-powered analysis and industry best practices. ## Context The user needs automated documentation generation that extracts information from code, creates clear explanations, and maintains consistency across documentation types. Focus on creating living documentation that stays synchronized with code. ## Requirements $ARGUMENTS ## Instructions ### 1. Code Analysis for Documentation Extract documentation elements from source code: API Documentation Extraction ``python import ast import inspect from typing import Dict, List, Any class APIDocExtractor: def extract_endpoints(self, code_path): """ Extract API endpoints and their documentation """ endpoints = [] # FastAPI example fastapi_decorators = ['@app.get', '@app.post', '@app.put', '@app.delete'] with open(code_path, 'r') as f: tree = ast.parse(f.read()) for node in ast.walk(tree): if isinstance(node, ast.FunctionDef): # Check for route decorators for decorator in node.decorator_list: if self._is_route_decorator(decorator): endpoint = { 'method': self._extract_method(decorator), 'path': self._extract_path(decorator), 'function': node.name, 'docstring': ast.get_docstring(node), 'parameters': self._extract_parameters(node), 'returns': self._extract_returns(node), 'examples': self._extract_examples(node) } endpoints.append(endpoint) return endpoints def _extract_parameters(self, func_node): """ Extract function parameters with types """ params = [] for arg in func_node.args.args: param = { 'name': arg.arg, 'type': None, 'required': True, 'description': '' } # Extract type annotation if arg.annotation: param['type'] = ast.unparse(arg.annotation) params.append(param) return params ` **Type and Schema Documentation** `python # Extract Pydantic models def extract_pydantic_schemas(file_path): """ Extract Pydantic model definitions for API documentation """ schemas = [] with open(file_path, 'r') as f: tree = ast.parse(f.read()) for node in ast.walk(tree): if isinstance(node, ast.ClassDef): # Check if inherits from BaseModel if any(base.id == 'BaseModel' for base in node.bases if hasattr(base, 'id')): schema = { 'name': node.name, 'description': ast.get_docstring(node), 'fields': [] } # Extract fields for item in node.body: if isinstance(item, ast.AnnAssign): field = { 'name': item.target.id, 'type': ast.unparse(item.annotation), 'required': item.value is None, 'default': ast.unparse(item.value) if item.value else None } schema['fields'].append(field) schemas.append(schema) return schemas # TypeScript interface extraction function extractTypeScriptInterfaces(code) { const interfaces = []; const interfaceRegex = /interface\s+(\w+)\s*{([^}]+)}/g; let match; while ((match = interfaceRegex.exec(code)) !== null) { const name = match[1]; const body = match[2]; const fields = []; const fieldRegex = /(\w+)(\?)?\s*:\s*([^;]+);/g; let fieldMatch; while ((fieldMatch = fieldRegex.exec(body)) !== null) { fields.push({ name: fieldMatch[1], required: !fieldMatch[2], type: fieldMatch[3].trim() }); } interfaces.push({ name, fields }); } return interfaces; } ` ### 2. API Documentation Generation Create comprehensive API documentation: **OpenAPI/Swagger Generation** ``yaml openapi: 3.0.0 info: title: ${APITITLE} version: ${VERSION} description: | ${DESCRIPTION} ## Authentication ${AUTHDESCRIPTION}
