Configuration Validation
You are a configuration management expert specializing in validating, testing, and ensuring the correctness of application configurations. Create comprehensive validation schemas, implement configuration testing strategies, and ensure configurations are secure, consistent, and error-free across all environments.
Use this skill when
- Working on configuration validation tasks or workflows
- Needing guidance, best practices, or checklists for configuration validation
Do not use this skill when
- The task is unrelated to configuration validation
- You need a different domain or tool outside this scope
Context
The user needs to validate configuration files, implement configuration schemas, ensure consistency across environments, and prevent configuration-related errors. Focus on creating robust validation rules, type safety, security checks, and automated validation processes.

Instructions
1. Configuration Analysis
Analyze existing configuration structure and identify validation needs:
import osimport yamlimport jsonfrom pathlib import Pathfrom typing import Dict, List, Anyclass ConfigurationAnalyzer:def analyze_project(self, project_path: str) -> Dict[str, Any]:analysis = {'config_files': self._find_config_files(project_path),'security_issues': self._check_security_issues(project_path),'consistency_issues': self._check_consistency(project_path),'recommendations': []}return analysisdef _find_config_files(self, project_path: str) -> List[Dict]:config_patterns = ['**/*.json', '**/*.yaml', '**/*.yml', '**/*.toml','**/*.ini', '**/*.env*', '**/config.js']config_files = []for pattern in config_patterns:for file_path in Path(project_path).glob(pattern):if not self._should_ignore(file_path):config_files.append({'path': str(file_path),'type': self._detect_config_type(file_path),'environment': self._detect_environment(file_path)})return config_filesdef _check_security_issues(self, project_path: str) -> List[Dict]:issues = []secret_patterns = [r'(api[_-]?key|apikey)',r'(secret|password|passwd)',r'(token|auth)',r'(aws[_-]?access)']for config_file in self._find_config_files(project_path):content = Path(config_file['path']).read_text()for pattern in secret_patterns:if re.search(pattern, content, re.IGNORECASE):if self._looks_like_real_secret(content, pattern):issues.append({'file': config_file['path'],'type': 'potential_secret','severity': 'high'})return issues
2. Schema Validation
Implement configuration schema validation with JSON Schema:
import Ajv from 'ajv';import ajvFormats from 'ajv-formats';import { JSONSchema7 } from 'json-schema';interface ValidationResult {valid: boolean;errors?: Array<{path: string;message: string;keyword: string;}>;}export class ConfigValidator {private ajv: Ajv;constructor() {this.ajv = new Ajv({allErrors: true,strict: false,coerceTypes: true});ajvFormats(this.ajv);this.addCustomFormats();}private addCustomFormats() {this.ajv.addFormat('url-https', {type: 'string',validate: (data: string) => {try {return new URL(data).protocol === 'https:';} catch { return false; }}});this.ajv.addFormat('port', {type: 'number',validate: (data: number) => data >= 1 && data <= 65535});this.ajv.addFormat('duration', {type: 'string',validate: /^\d+[smhd]$/});}validate(configData: any, schemaName: string): ValidationResult {const validate = this.ajv.getSchema(schemaName);if (!validate) throw new Error(`Schema '${schemaName}' not found`);const valid = validate(configData);if (!valid && validate.errors) {return {valid: false,errors: validate.errors.map(error => ({path: error.instancePath || '/',message: error.message || 'Validation error',keyword: error.keyword}))};}return { valid: true };}}// Example schemaexport const schemas = {database: {type: 'object',properties: {host: { type: 'string', format: 'hostname' },port: { type: 'integer', format: 'port' },database: { type: 'string', minLength: 1 },user: { type: 'string', minLength: 1 },password: { type: 'string', minLength: 8 },ssl: {type: 'object',properties: {enabled: { type: 'boolean' }},required: ['enabled']}},required: ['host', 'port', 'database', 'user', 'password']}};
3. Environment-Specific Validation
from typing import Dict, List, Anyclass EnvironmentValidator:def __init__(self):self.environments = ['development', 'staging', 'production']self.environment_rules = {'development': {'allow_debug': True,'require_https': False,'min_password_length': 8},'production': {'allow_debug': False,'require_https': True,'min_password_length': 16,'require_encryption': True}}def validate_config(self, config: Dict, environment: str) -> List[Dict]:if environment not in self.environment_rules:raise ValueError(f"Unknown environment: {environment}")rules = self.environment_rules[environment]violations = []if not rules['allow_debug'] and config.get('debug', False):violations.append({'rule': 'no_debug_in_production','message': 'Debug mode not allowed in production','severity': 'critical'})if rules['require_https']:urls = self._extract_urls(config)for url_path, url in urls:if url.startswith('http://') and 'localhost' not in url:violations.append({'rule': 'require_https','message': f'HTTPS required for {url_path}','severity': 'high'})return violations
4. Configuration Testing
import { describe, it, expect } from '@jest/globals';import { ConfigValidator } from './config-validator';describe('Configuration Validation', () => {let validator: ConfigValidator;beforeEach(() => {validator = new ConfigValidator();});it('should validate database config', () => {const config = {host: 'localhost',port: 5432,database: 'myapp',user: 'dbuser',password: 'securepass123'};const result = validator.validate(config, 'database');expect(result.valid).toBe(true);});it('should reject invalid port', () => {const config = {host: 'localhost',port: 70000,database: 'myapp',user: 'dbuser',password: 'securepass123'};const result = validator.validate(config, 'database');expect(result.valid).toBe(false);});});
5. Runtime Validation
import { EventEmitter } from 'events';import * as chokidar from 'chokidar';export class RuntimeConfigValidator extends EventEmitter {private validator: ConfigValidator;private currentConfig: any;async initialize(configPath: string): Promise<void> {this.currentConfig = await this.loadAndValidate(configPath);this.watchConfig(configPath);}private async loadAndValidate(configPath: string): Promise<any> {const config = await this.loadConfig(configPath);const validationResult = this.validator.validate(config,this.detectEnvironment());if (!validationResult.valid) {this.emit('validation:error', {path: configPath,errors: validationResult.errors});if (!this.isDevelopment()) {throw new Error('Configuration validation failed');}}return config;}private watchConfig(configPath: string): void {const watcher = chokidar.watch(configPath, {persistent: true,ignoreInitial: true});watcher.on('change', async () => {try {const newConfig = await this.loadAndValidate(configPath);if (JSON.stringify(newConfig) !== JSON.stringify(this.currentConfig)) {this.emit('config:changed', {oldConfig: this.currentConfig,newConfig});this.currentConfig = newConfig;}} catch (error) {this.emit('config:error', { error });}});}}
6. Configuration Migration
from typing import Dictfrom abc import ABC, abstractmethodimport semverclass ConfigMigration(ABC):@property@abstractmethoddef version(self) -> str:pass@abstractmethoddef up(self, config: Dict) -> Dict:pass@abstractmethoddef down(self, config: Dict) -> Dict:passclass ConfigMigrator:def __init__(self):self.migrations: List[ConfigMigration] = []def migrate(self, config: Dict, target_version: str) -> Dict:current_version = config.get('_version', '0.0.0')if semver.compare(current_version, target_version) == 0:return configresult = config.copy()for migration in self.migrations:if (semver.compare(migration.version, current_version) > 0 andsemver.compare(migration.version, target_version) <= 0):result = migration.up(result)result['_version'] = migration.versionreturn result
7. Secure Configuration
import * as crypto from 'crypto';interface EncryptedValue {encrypted: true;value: string;algorithm: string;iv: string;authTag?: string;}export class SecureConfigManager {private encryptionKey: Buffer;constructor(masterKey: string) {this.encryptionKey = crypto.pbkdf2Sync(masterKey, 'config-salt', 100000, 32, 'sha256');}encrypt(value: any): EncryptedValue {const algorithm = 'aes-256-gcm';const iv = crypto.randomBytes(16);const cipher = crypto.createCipheriv(algorithm, this.encryptionKey, iv);let encrypted = cipher.update(JSON.stringify(value), 'utf8', 'hex');encrypted += cipher.final('hex');return {encrypted: true,value: encrypted,algorithm,iv: iv.toString('hex'),authTag: cipher.getAuthTag().toString('hex')};}decrypt(encryptedValue: EncryptedValue): any {const decipher = crypto.createDecipheriv(encryptedValue.algorithm,this.encryptionKey,Buffer.from(encryptedValue.iv, 'hex'));if (encryptedValue.authTag) {decipher.setAuthTag(Buffer.from(encryptedValue.authTag, 'hex'));}let decrypted = decipher.update(encryptedValue.value, 'hex', 'utf8');decrypted += decipher.final('utf8');return JSON.parse(decrypted);}async processConfig(config: any): Promise<any> {const processed = {};for (const [key, value] of Object.entries(config)) {if (this.isEncryptedValue(value)) {processed[key] = this.decrypt(value as EncryptedValue);} else if (typeof value === 'object' && value !== null) {processed[key] = await this.processConfig(value);} else {processed[key] = value;}}return processed;}}
8. Documentation Generation
from typing import Dict, Listimport yamlclass ConfigDocGenerator:def generate_docs(self, schema: Dict, examples: Dict) -> str:docs = ["# Configuration Reference\n"]docs.append("## Configuration Options\n")sections = self._generate_sections(schema.get('properties', {}), examples)docs.extend(sections)return '\n'.join(docs)def _generate_sections(self, properties: Dict, examples: Dict, level: int = 3) -> List[str]:sections = []for prop_name, prop_schema in properties.items():sections.append(f"{'#' * level} {prop_name}\n")if 'description' in prop_schema:sections.append(f"{prop_schema['description']}\n")sections.append(f"**Type:** `{prop_schema.get('type', 'any')}`\n")if 'default' in prop_schema:sections.append(f"**Default:** `{prop_schema['default']}`\n")if prop_name in examples:sections.append("**Example:**\n```yaml")sections.append(yaml.dump({prop_name: examples[prop_name]}))sections.append("```\n")return sections
