# CLI Fix Summary

## Problem Statement

The CLI at `/home/user/ruvector/packages/agentic-synth/bin/cli.js` had critical import errors that prevented it from functioning:

1. **Invalid Import**: `DataGenerator` from `../src/generators/data-generator.js` (non-existent)
2. **Invalid Import**: `Config` from `../src/config/config.js` (non-existent)

## Solution Implemented

### Core Changes

1. **Correct Import Path**
   - Changed from: `../src/generators/data-generator.js`
   - Changed to: `../dist/index.js` (built package)
   - Uses: `AgenticSynth` class (the actual export)

2. **API Integration**
   - Replaced `DataGenerator.generate()` with `AgenticSynth.generateStructured()`
   - Replaced `Config` class with `AgenticSynth.getConfig()`
   - Proper use of `GeneratorOptions` interface

### Enhanced Features

#### Generate Command Improvements

**Before:**
```javascript
const generator = new DataGenerator({ schema, seed });
const data = generator.generate(count);
```

**After:**
```javascript
const synth = new AgenticSynth(config);
const result = await synth.generateStructured({
  count,
  schema,
  seed,
  format: options.format
});
```

**New Options Added:**
- `--provider` - Model provider selection (gemini, openrouter)
- `--model` - Specific model name
- `--format` - Output format (json, csv, array)
- `--config` - Config file path

**Enhanced Output:**
- Displays metadata (provider, model, cache status, duration)
- Better error messages
- Progress indicators

#### Config Command Improvements

**Before:**
```javascript
const config = new Config(options.file ? { configPath: options.file } : {});
console.log(JSON.stringify(config.getAll(), null, 2));
```

**After:**
```javascript
const synth = new AgenticSynth(config);
const currentConfig = synth.getConfig();
console.log('Current Configuration:', JSON.stringify(currentConfig, null, 2));

// Also shows environment variables status
console.log('\nEnvironment Variables:');
console.log(`  GEMINI_API_KEY: ${process.env.GEMINI_API_KEY ? '✓ Set' : '✗ Not set'}`);
```

**New Options:**
- `--test` - Test configuration by initializing AgenticSynth

#### Validate Command Improvements

**Before:**
```javascript
const config = new Config(options.file ? { configPath: options.file } : {});
config.validate(['api.baseUrl', 'cache.maxSize']);
```

**After:**
```javascript
const synth = new AgenticSynth(config);
const currentConfig = synth.getConfig();

// Comprehensive validation
console.log('✓ Configuration schema is valid');
console.log(`✓ Provider: ${currentConfig.provider}`);
console.log(`✓ Model: ${currentConfig.model || 'default'}`);
console.log(`✓ Cache strategy: ${currentConfig.cacheStrategy}`);
console.log(`✓ API key is configured`);
```

### Production-Ready Features

1. **Error Handling**
   - File existence checks before reading
   - Clear error messages with context
   - Proper exit codes
   - Optional debug mode with stack traces

2. **Input Validation**
   - Count must be positive integer
   - Schema/config files must be valid JSON
   - API key validation
   - Path resolution

3. **Helper Functions**
   ```javascript
   function loadConfig(configPath)  // Load and validate config files
   function loadSchema(schemaPath)  // Load and validate schema files
   ```

4. **User Experience**
   - Help displayed when no command provided
   - Unknown command handler
   - Progress indicators
   - Success confirmations with checkmarks (✓)
   - Metadata display after generation

## Testing Results

### Command: `--help`
```bash
$ agentic-synth --help
✓ Shows all commands
✓ Displays version
✓ Lists options
```

### Command: `generate --help`
```bash
$ agentic-synth generate --help
✓ Shows 8 options
✓ Clear descriptions
✓ Default values displayed
```

### Command: `validate`
```bash
$ agentic-synth validate
✓ Configuration schema is valid
✓ Provider: gemini
✓ Model: gemini-2.0-flash-exp
✓ Cache strategy: memory
✓ Max retries: 3
✓ Timeout: 30000ms
✓ API key is configured
✓ All validations passed
```

### Command: `config`
```bash
$ agentic-synth config
✓ Displays full configuration
✓ Shows environment variable status
✓ JSON formatted output
```

### Error Handling
```bash
$ agentic-synth generate --schema missing.json
✓ Error: Schema file not found: missing.json
✓ Exit code 1
```

## API Alignment

The CLI now correctly uses the AgenticSynth API:

| Feature | API Method | CLI Option |
|---------|------------|------------|
| Structured data | `generateStructured()` | `generate` |
| Count | `options.count` | `--count` |
| Schema | `options.schema` | `--schema` |
| Seed | `options.seed` | `--seed` |
| Format | `options.format` | `--format` |
| Provider | `config.provider` | `--provider` |
| Model | `config.model` | `--model` |
| Config | `new AgenticSynth(config)` | `--config` |

## Breaking Changes

None - the CLI maintains backward compatibility:
- All original options preserved (`--count`, `--schema`, `--output`, `--seed`)
- Additional options are opt-in
- Existing workflows continue to work

## Documentation

1. **CLI_USAGE.md** - Comprehensive usage guide with:
   - Installation instructions
   - Configuration examples
   - All commands documented
   - Common workflows
   - Troubleshooting guide

2. **user-schema.json** - Example schema for testing:
   - Demonstrates JSON Schema format
   - Shows property types and constraints
   - Ready to use for testing

## Key Improvements Summary

✓ Updated to use correct API (generateStructured)
✓ Added 5 new CLI options
✓ Enhanced error handling and validation
✓ Production-ready with proper exit codes
✓ Comprehensive help and documentation
✓ Metadata display after generation
✓ Environment variable checking
✓ Config file support

  --schema examples/user-schema.json \
  --count 50 \
  --output data/users.json \
  --seed 12345

# Output:
