## Installation

### For Users

Make sure you have Node.js 18 or later installed:
```bash
node --version  # Should be >= 18.0.0
```

Then install the CLI globally:
```bash
# Install globally from npm
npm install -g @sagaegmi/prompthub-cli

# Or install from source
git clone https://github.com/sagarregmi2056/prompthub-cli.git
cd prompthub-cli
npm install
npm link
```

### Troubleshooting Installation

If you encounter any issues during installation:

1. Ensure you're using Node.js 18 or later:
   ```bash
   node --version
   ```

2. If using an older version, update Node.js:
   - Windows: Download from [nodejs.org](https://nodejs.org/)
   - Mac: `brew upgrade node`
   - Linux: Use [Node Version Manager](https://github.com/nvm-sh/nvm)

3. Clear npm cache if needed:
   ```bash
   npm cache clean --force
   ```

### For Developers

```bash
# Clone the repository
git clone https://github.com/sagarregmi2056/prompthub-cli.git

# Navigate to the project directory
cd prompthub-cli

# Install dependencies
npm install

# Link the CLI globally for testing
npm link

# Run tests
npm test

# Run linter
npm run lint

# Format code
npm run format
```

## Configuration

### Required Environment Variables

The CLI requires configuration for basic operation and remote storage. When you first run any command, if no `.env` file is found, a template will be created automatically:

```env
# Required for prompt execution
OPENAI_API_KEY=your_api_key_here

# Optional: Remote storage configuration
# S3 Storage
S3_BUCKET=your-bucket-name
S3_REGION=your-region
AWS_ACCESS_KEY_ID=your-access-key
AWS_SECRET_ACCESS_KEY=your-secret-key

# GitHub Storage
GITHUB_TOKEN=your-github-token
GITHUB_REPO=owner/repo

# REST API Storage
REST_API_URL=https://your-api.com
REST_API_KEY=your-api-key

# Model Configuration
MODEL=gpt-4  # Default model to use
MAX_TOKENS=2000  # Maximum tokens for responses
```

### Remote Storage Setup

PromptHub supports three types of remote storage:

1. **S3 Storage**
```bash
# Configure S3
prompthub remote s3 --bucket my-prompts --region us-east-1

# Required environment variables:
# - S3_BUCKET
# - S3_REGION
# - AWS_ACCESS_KEY_ID
# - AWS_SECRET_ACCESS_KEY
```

2. **GitHub Storage**
```bash
# Configure GitHub
prompthub remote github --repo owner/repo

# Required environment variables:
# - GITHUB_TOKEN
# - GITHUB_REPO
```

3. **REST API Storage**
```bash
# Configure REST API
prompthub remote rest --url https://api.example.com

# Required environment variables:
# - REST_API_URL
# - REST_API_KEY
```

## Usage

### Initialize in a Project

```bash
prompthub init
```

### Branch Management

```bash
# Create a new branch
prompthub branch feature/tone --create

# Switch to a branch
prompthub branch feature/tone

# List prompts in a branch
prompthub list -b feature/tone
```

### Save a Prompt

```bash
# Save a prompt directly
prompthub save -p "Explain quantum computing" -t quantum physics

# Save to a specific branch
prompthub save -p "Your prompt" -b feature/tone

# Save a prompt from a file
prompthub save -f ./prompt.txt --tags ai research

# Save without executing
prompthub save -p "Your prompt" --no-execute

# Save without checking for outdated prompts
prompthub save -p "Your prompt" --skip-outdated-check
```

### Create Prompt Variants

```bash
# Fork a prompt with new text
prompthub fork abc123 -p "Explain quantum computing with more examples"

# Fork using parent's prompt text
prompthub fork abc123

# Fork with additional tags
prompthub fork abc123 -t advanced examples

# Fork from file
prompthub fork abc123 -f ./variant.txt
```

### A/B Testing

```bash
# Simple A/B test
prompthub test abc123 def456

# Run multiple samples
prompthub test abc123 def456 -n 10

# Test with specific model
prompthub test abc123 def456 --model gpt-4

# Export results to CSV
prompthub test abc123 def456 -n 5 -o results.csv
```

The CSV output includes:
- Prompt IDs and text
- Average token usage
- Average latency
- Sample responses

### Track Prompt Lineage

```bash
# Show full ancestry tree of a prompt
prompthub lineage abc123

# Check for outdated prompts
prompthub check-outdated
```

### List and Search

```bash
# List prompts in current branch
prompthub list

# List with limit
prompthub list -n 20

# List prompts with specific tag
prompthub list -t research

# List prompts in specific branch
prompthub list -b feature/tone

# Search in specific branch
prompthub search "quantum" -b feature/tone

# Output in JSON format
prompthub list --format json
```

### Compare and Restore

```bash
# Show diff between two versions
prompthub diff abc123 def456

# Restore to specific branch
prompthub restore abc123 -b feature/tone
```

## Team Collaboration Workflow

1. **Set Up Remote Storage**
```bash
# Team lead configures remote storage
prompthub remote s3 --bucket team-prompts --region us-east-1
```

2. **Create Feature Branch**
```bash
# Create branch for new feature
prompthub branch feature/tone-improvement --create
```

3. **Work on Prompts**
```bash
# Save prompts to branch
prompthub save -p "New tone prompt" -b feature/tone-improvement

# Test variations
prompthub fork abc123 -p "Alternative tone" -b feature/tone-improvement
prompthub test def456 ghi789 -n 5 -o tone-test.csv
```

4. **Review Changes**
```bash
# Check for outdated prompts
prompthub check-outdated

# Review lineage
prompthub lineage abc123
```

## CI/CD Integration

PromptHub CLI can be integrated into your CI/CD pipeline:

```yaml
# Example GitHub Actions workflow
name: Prompt Validation
on: [push]

jobs:
  validate-prompts:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Install PromptHub CLI
        run: npm install -g @sagarregmi2056/prompthub-cli
      
      - name: Run A/B Tests
        run: |
          prompthub test ${{ github.event.inputs.prompt1 }} ${{ github.event.inputs.prompt2 }} -n 5 -o test-results.csv
      
      - name: Check Outdated Prompts
        run: prompthub check-outdated
```

## Best Practices

1. **Branch Management**
   - Use branches for experimental prompt variations
   - Keep main branch for production-ready prompts
   - Test variations before merging

2. **A/B Testing**
   - Run multiple samples for statistical significance
   - Export results to CSV for analysis
   - Test with the same model you'll use in production

3. **Remote Storage**
   - Use S3 for large teams and high availability
   - Use GitHub for version control integration
   - Use REST API for custom backend integration

4. **Prompt Lineage**
   - Fork prompts for significant variations
   - Keep track of parent-child relationships
   - Regularly check for outdated variants

5. **CI/CD Integration**
   - Automate prompt testing
   - Validate prompts before deployment
   - Track metrics over time

```

### Adding New Commands

1. Create a new command file in `lib/commands/`
2. Export the command function
3. Add the command to `lib/commands/index.js`
4. Register the command in `bin/cli.js`

Example:
```javascript
// lib/commands/yourcommand.js
export async function yourCommand(options) {
  // Implementation
}

// lib/commands/index.js
export { yourCommand } from './yourcommand.js';

// bin/cli.js
program
  .command('yourcommand')
  .description('Your command description')
  .option('-o, --option', 'Option description')
  .action(yourCommand);
```

### Storage System

The file-based storage system is implemented in `lib/db/store.js`. Key features:

- Each prompt is stored as a separate JSON file
- Files are named using the prompt ID (e.g., `abc123.json`)
- Tags are stored in a central `tags.json` file
- All storage is human-readable and easily inspectable
- No database dependencies required

### Contributing

1. Fork the repository
2. Create your feature branch (`git checkout -b feature/amazing-feature`)
3. Commit your changes (`git commit -m 'Add some amazing feature'`)
4. Push to the branch (`git push origin feature/amazing-feature`)
5. Open a Pull Request

### Testing

```bash
# Run all tests
npm test

# Run tests in watch mode
npm test -- --watch

# Run tests with coverage
npm test -- --coverage
