6# Configuration Validation
7 
8You 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.
9 
10## Use this skill when
11 
12- Working on configuration validation tasks or workflows
13- Needing guidance, best practices, or checklists for configuration validation
14 
15## Do not use this skill when
16 
17- The task is unrelated to configuration validation
18- You need a different domain or tool outside this scope
19 
20## Context
21The 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.

26## Instructions
27 
28### 1. Configuration Analysis
29 
30Analyze existing configuration structure and identify validation needs:
31 
32```python
33import os
34import yaml
35import json
36from pathlib import Path
37from typing import Dict, List, Any
38 
39class ConfigurationAnalyzer:
40    def analyze_project(self, project_path: str) -> Dict[str, Any]:
41        analysis = {
42            'config_files': self._find_config_files(project_path),
43            'security_issues': self._check_security_issues(project_path),
44            'consistency_issues': self._check_consistency(project_path),
45            'recommendations': []
46        }
47        return analysis
48 
49    def _find_config_files(self, project_path: str) -> List[Dict]:
50        config_patterns = [
51            '**/*.json', '**/*.yaml', '**/*.yml', '**/*.toml',
52            '**/*.ini', '**/*.env*', '**/config.js'
53        ]
54 
55        config_files = []
56        for pattern in config_patterns:
57            for file_path in Path(project_path).glob(pattern):
58                if not self._should_ignore(file_path):
59                    config_files.append({
60                        'path': str(file_path),
61                        'type': self._detect_config_type(file_path),
62                        'environment': self._detect_environment(file_path)
63                    })
64        return config_files
65 
66    def _check_security_issues(self, project_path: str) -> List[Dict]:
67        issues = []
68        secret_patterns = [
69            r'(api[_-]?key|apikey)',
70            r'(secret|password|passwd)',
71            r'(token|auth)',
72            r'(aws[_-]?access)'
73        ]
74 
75        for config_file in self._find_config_files(project_path):
76            content = Path(config_file['path']).read_text()
77            for pattern in secret_patterns:
78                if re.search(pattern, content, re.IGNORECASE):
79                    if self._looks_like_real_secret(content, pattern):
80                        issues.append({
81                            'file': config_file['path'],
82                            'type': 'potential_secret',
83                            'severity': 'high'
84                        })
85        return issues
86```
87 
88### 2. Schema Validation
89 
90Implement configuration schema validation with JSON Schema:
91 
92```typescript
93import Ajv from 'ajv';
94import ajvFormats from 'ajv-formats';
95import { JSONSchema7 } from 'json-schema';
96 
97interface ValidationResult {
98  valid: boolean;
99  errors?: Array<{
100    path: string;
101    message: string;
102    keyword: string;
103  }>;
104}
105 
106export class ConfigValidator {
107  private ajv: Ajv;
108 
109  constructor() {
110    this.ajv = new Ajv({
111      allErrors: true,
112      strict: false,
113      coerceTypes: true
114    });
115    ajvFormats(this.ajv);
116    this.addCustomFormats();
117  }
118 
119  private addCustomFormats() {
120    this.ajv.addFormat('url-https', {
121      type: 'string',
122      validate: (data: string) => {
123        try {
124          return new URL(data).protocol === 'https:';
125        } catch { return false; }
126      }
127    });
128 
129    this.ajv.addFormat('port', {
130      type: 'number',
131      validate: (data: number) => data >= 1 && data <= 65535
132    });
133 
134    this.ajv.addFormat('duration', {
135      type: 'string',
136      validate: /^\d+[smhd]$/
137    });
138  }
139 
140  validate(configData: any, schemaName: string): ValidationResult {
141    const validate = this.ajv.getSchema(schemaName);
142    if (!validate) throw new Error(`Schema '${schemaName}' not found`);
143 
144    const valid = validate(configData);
145 
146    if (!valid && validate.errors) {
147      return {
148        valid: false,
149        errors: validate.errors.map(error => ({
150          path: error.instancePath || '/',
151          message: error.message || 'Validation error',
152          keyword: error.keyword
153        }))
154      };
155    }
156    return { valid: true };
157  }
158}
159 
160// Example schema
161export const schemas = {
162  database: {
163    type: 'object',
164    properties: {
165      host: { type: 'string', format: 'hostname' },
166      port: { type: 'integer', format: 'port' },
167      database: { type: 'string', minLength: 1 },
168      user: { type: 'string', minLength: 1 },
169      password: { type: 'string', minLength: 8 },
170      ssl: {
171        type: 'object',
172        properties: {
173          enabled: { type: 'boolean' }
174        },
175        required: ['enabled']
176      }
177    },
178    required: ['host', 'port', 'database', 'user', 'password']
179  }
180};
181```
182 
183### 3. Environment-Specific Validation
184 
185```python
186from typing import Dict, List, Any
187 
188class EnvironmentValidator:
189    def __init__(self):
190        self.environments = ['development', 'staging', 'production']
191        self.environment_rules = {

201                'require_encryption': True
202            }
203        }
204 
205    def validate_config(self, config: Dict, environment: str) -> List[Dict]:
206        if environment not in self.environment_rules:
207            raise ValueError(f"Unknown environment: {environment}")
208 
209        rules = self.environment_rules[environment]
210        violations = []
211 
212        if not rules['allow_debug'] and config.get('debug', False):
213            violations.append({
214                'rule': 'no_debug_in_production',
215                'message': 'Debug mode not allowed in production',
216                'severity': 'critical'
217            })
218 
219        if rules['require_https']:
220            urls = self._extract_urls(config)
221            for url_path, url in urls:
222                if url.startswith('http://') and 'localhost' not in url:
223                    violations.append({
224                        'rule': 'require_https',

227                    })
228 
229        return violations
230```
231 
232### 4. Configuration Testing
233 
234```typescript
235import { describe, it, expect } from '@jest/globals';
236import { ConfigValidator } from './config-validator';
237 
238describe('Configuration Validation', () => {
239  let validator: ConfigValidator;
240 
241  beforeEach(() => {
242    validator = new ConfigValidator();
243  });
244 
245  it('should validate database config', () => {
246    const config = {
247      host: 'localhost',
248      port: 5432,

252    };
253 
254    const result = validator.validate(config, 'database');

267    const result = validator.validate(config, 'database');
268    expect(result.valid).toBe(false);
269  });
270});
271```
272 
273### 5. Runtime Validation
274 
275```typescript
276import { EventEmitter } from 'events';
277import * as chokidar from 'chokidar';
278 
279export class RuntimeConfigValidator extends EventEmitter {

329      }
330    });
331  }
332}
333```
334 
335### 6. Configuration Migration
336 
337```python
