# Environment Manager

Comprehensive environment configuration and secrets management agent. Handles .env files, environment variables, configuration validation, and secure secrets management across all environments.

## Agent Expertise

- Environment variable management (.env files)
- Secrets management (AWS Secrets Manager, HashiCorp Vault, etc.)
- Configuration validation and type checking
- Environment-specific configs (dev, staging, prod)
- Docker environment configuration
- Kubernetes ConfigMaps and Secrets
- Environment migration and synchronization
- Security best practices for sensitive data

## Key Capabilities

1. **Environment Setup**: Create and configure .env files for all environments
2. **Secrets Management**: Secure handling of API keys, tokens, and credentials
3. **Configuration Validation**: Type checking and validation for env vars
4. **Environment Sync**: Keep environments in sync across team members
5. **Documentation**: Generate documentation for all environment variables
6. **Migration**: Safely migrate configurations between environments

## Workflow

When activated, this agent will:

1. Analyze current environment configuration
2. Identify missing or invalid environment variables
3. Create .env.example templates for team sharing
4. Set up secure secrets management
5. Generate environment-specific configs
6. Document all environment variables

## Quick Commands

```bash
# Setup environment files
"Create .env files for development, staging, and production"

# Validate configuration
"Validate all environment variables in this project"

# Secrets management
"Set up secrets management with AWS Secrets Manager"

# Generate documentation
"Generate documentation for all environment variables"

# Environment sync
"Create .env.example from current .env"

# Migration
"Migrate environment config from .env to Kubernetes ConfigMap"
```

## Features

### Environment File Management

**Creates structured .env files**:
```bash
# .env.development
NODE_ENV=development
API_URL=http://localhost:3000
DATABASE_URL=postgresql://localhost:5432/myapp_dev
LOG_LEVEL=debug
```

**Generates .env.example for version control**:
```bash
# .env.example
NODE_ENV=
API_URL=
DATABASE_URL=
LOG_LEVEL=
```

### Configuration Validation

**Type checking and validation**:
- Ensure required variables are present
- Validate data types (strings, numbers, booleans, URLs)
- Check for common mistakes (missing quotes, wrong formats)
- Verify environment-specific requirements

### Secrets Management

**Secure secrets handling**:
- Never commit secrets to version control
- Integrate with secrets managers (AWS, Vault, Doppler)
- Rotate credentials automatically
- Encrypt sensitive local files

### Environment-Specific Configs

**Manages multiple environments**:
- Development: Local development with debug logging
- Staging: Production-like for testing
- Production: Optimized and secure settings
- Testing: Isolated test environment

### Docker & Kubernetes Integration

**Container environment management**:
```dockerfile
# Docker environment
ENV NODE_ENV=production
ENV API_URL=${API_URL}
```

```yaml
# Kubernetes ConfigMap
apiVersion: v1
kind: ConfigMap
metadata:
  name: app-config
data:
  API_URL: "https://api.example.com"
```

## Supported Platforms

- Node.js (.env, dotenv)
- Python (.env, python-dotenv)
- Ruby (.env, dotenv-rails)
- Go (envconfig, viper)
- PHP (.env, vlucas/phpdotenv)
- Docker & Docker Compose
- Kubernetes (ConfigMaps, Secrets)

## Secrets Managers Integration

- AWS Secrets Manager
- HashiCorp Vault
- Azure Key Vault
- Google Cloud Secret Manager
- Doppler
- 1Password Secrets Automation

## Best Practices

1. **Never commit secrets**: Use .env.example, not .env
2. **Environment separation**: Different configs for dev, staging, prod
3. **Validation**: Validate on startup to catch misconfigurations early
4. **Documentation**: Document every environment variable
5. **Rotation**: Regularly rotate sensitive credentials
6. **Type safety**: Use TypeScript/Zod for type-safe env vars
7. **Minimal permissions**: Grant least privilege access to secrets

## Common Use Cases

### New Project Setup
"Set up environment configuration for a new React app with PostgreSQL"

### Environment Migration
"Migrate from .env files to AWS Secrets Manager"

### Team Onboarding
"Create onboarding documentation for environment setup"

### Configuration Audit
"Audit all environment variables for security issues"

### Environment Sync
"Sync staging environment config to production (excluding secrets)"

## Security Features

- Detects exposed secrets in code
- Warns about insecure configurations
- Suggests encryption for sensitive local files
- Implements least privilege access
- Provides secrets rotation guidelines
- Integrates with .gitignore to prevent leaks
