## Environment Variable Configuration

### Setting API Keys via Environment Variables

Instead of storing API keys directly in configuration files, you can reference environment variables:

1. **During configuration**, enter `env:VARIABLE_NAME` when prompted for API key
2. **Set the environment variable** in your shell or `.env` file:
   ```bash
   export OPENAI_API_KEY="your-actual-api-key"
   export ANTHROPIC_API_KEY="your-anthropic-key"
   export GOOGLE_API_KEY="your-google-key"
   ```

### Supported Environment Variable Patterns

- `env:OPENAI_API_KEY` → resolves to `process.env.OPENAI_API_KEY`
- `env:ANTHROPIC_API_KEY` → resolves to `process.env.ANTHROPIC_API_KEY`
- `env:CUSTOM_KEY_NAME` → resolves to `process.env.CUSTOM_KEY_NAME`

### Benefits

- **Security**: API keys are not stored in configuration files
- **Flexibility**: Different environments can use different keys
- **Portability**: Configuration works across different machines
- **CI/CD Friendly**: Easy to use in automated environments

## Configuration Files

### Provider Configurations
Individual provider configurations are stored in:
```
.config/llm_config/
├── openai.json
├── anthropic.json
├── google.json
└── ...
```

### Global Configuration
Default provider and global settings are stored in:
```
.config/global_config.json
```

Example global config:
```json
{
  "defaultProvider": "OpenAI"
}
```

## Integration with Other Commands

Once configured, providers can be used with:

- **Chat Command**: `contaigents chat` (uses default provider)
- **Chat with Specific Provider**: `contaigents chat --provider anthropic`
- **Audio Generation**: `contaigents audio --provider google`

## Troubleshooting

### Environment Variable Not Found
If you see warnings like:
```
⚠️ Environment variable OPENAI_API_KEY not found for OpenAI.apiKey
```

Make sure to:
1. Set the environment variable: `export OPENAI_API_KEY="your-key"`
2. Restart your terminal or reload your shell configuration
3. Verify the variable is set: `echo $OPENAI_API_KEY`

### Provider Not Configured
If you get errors about unconfigured providers:
1. Run `contaigents configure` to set up the provider
2. Make sure all required fields are filled
3. Verify environment variables are properly set

### Reconfiguring a Provider
To reconfigure an existing provider:
1. Run `contaigents configure` again
2. Select the same provider
3. Enter new configuration values
4. The old configuration will be overwritten
