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 os
import yaml
import json
from pathlib import Path
from typing import Dict , List , Any
class 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 analysis
def

'**/*.yaml'
'**/*.yml'
'**/*.toml'
'**/*.ini'
'**/*.env*'

if
self
'file'

return
2. Schema Validation Implement configuration schema validation with JSON Schema:
import Ajv from 'ajv' ;
import ajvFormats from 'ajv-formats' ;
import { JSON Schema7 } 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 };
}
}
export 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 , Any
class EnvironmentValidator :
def __init__ (self ):
self .environments = ['development' , 'staging' , 'production' ]

'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
