# Configuration Migrator Skill

Migrates configuration files between different formats and versions, handles environment variable extraction, and manages secret detection.

## Purpose

Enable configuration migration for:
- Config format conversion
- Environment variable extraction
- Secret detection and handling
- Schema validation
- Template generation

## Capabilities

### 1. Config Format Conversion
- XML to YAML/JSON
- Properties to YAML
- INI to JSON
- TOML conversion
- ENV file handling

### 2. Environment Variable Extraction
- Identify environment-specific values
- Extract to env files
- Create variable references
- Document variables

### 3. Secret Detection
- Find hardcoded secrets
- Identify credentials
- Detect API keys
- Flag sensitive data

### 4. Schema Validation
- Validate against schemas
- Check required fields
- Verify data types
- Ensure compatibility

### 5. Default Value Handling
- Preserve defaults
- Document required overrides
- Create sensible defaults
- Handle missing values

### 6. Template Generation
- Create config templates
- Generate example files
- Document all options
- Support multiple environments

| Tool | Purpose | Integration Method |
|------|---------|-------------------|
| yq | YAML processing | CLI |
| jq | JSON processing | CLI |
| dotenv | ENV file handling | Library |
