# SKIP_OLLAMA Feature Documentation

## Overview
The SKIP_OLLAMA feature allows users to run the shell setup script without installing Ollama Docker containers and related AI infrastructure. This is useful for environments where:

- Docker is not available or desired
- Local AI models are not needed
- Users prefer external AI providers (OpenAI, Anthropic, Google, etc.)
- Resource constraints make running local AI models impractical

## Usage

### Method 1: Environment Variable
```bash
export SKIP_OLLAMA=true
./setup/setup.sh
```

### Method 2: Inline Variable
```bash
SKIP_OLLAMA=true ./setup/setup.sh
```

### Method 3: Convenience Script
```bash
./setup-no-ollama.sh
```

## What Gets Skipped

When SKIP_OLLAMA=true, the following components are NOT installed:

1. **Ollama Docker Container**: No Docker container setup for local AI models
2. **Ollama Docker Aliases**: No shell aliases for Ollama container management
3. **Local AI Models**: No phi3:mini or other local models downloaded
4. **Ollama-specific Fabric Configuration**: Fabric is configured for external providers

## What Still Gets Installed

The following components are still installed normally:

1. **Fabric CLI Tool**: AI pattern processing tool for text manipulation
2. **All Other Packages**: Everything from setup/packages.list except Ollama
3. **Shell Configuration**: Zsh, Oh My Zsh, plugins, and dotfiles
4. **Development Tools**: Node.js, VS Code, Git, and other development utilities

## Fabric Configuration

When SKIP_OLLAMA=true, Fabric is installed but configured differently:

### Standard Configuration (with Ollama):
```env
# Fabric Configuration for Ollama
DEFAULT_MODEL=phi3:mini
OLLAMA_API_BASE=http://localhost:11434
```

### Skip Ollama Configuration:
```env
# Fabric Configuration - Ollama installation skipped
# Configure your preferred AI provider (OpenAI, Anthropic, Google, etc.)
# DEFAULT_MODEL=your_model_here
# OPENAI_API_KEY=your_key_here
# For more configuration options, see: fabric --help
```

## Post-Installation Configuration

After running setup with SKIP_OLLAMA=true, configure your preferred AI provider:

1. **Edit the Fabric configuration**:
   ```bash
   nano ~/.config/fabric/.env
   ```

2. **Add your preferred provider**:
   ```env
   # Example for OpenAI
   OPENAI_API_KEY=your_api_key_here
   DEFAULT_MODEL=gpt-4

   # Example for Anthropic
   ANTHROPIC_API_KEY=your_api_key_here
   DEFAULT_MODEL=claude-3-sonnet-20240229

   # Example for Google
   GOOGLE_API_KEY=your_api_key_here
   DEFAULT_MODEL=gemini-pro
   ```

3. **Test the configuration**:
   ```bash
   fabric --list-patterns
   echo "Test text" | fabric -p summarize
   ```

## Implementation Details

The SKIP_OLLAMA feature is implemented through conditional blocks in setup.sh:

- Lines 369-510: Main Ollama Docker setup wrapped in conditional
- Lines 276-340: Fabric configuration adapts based on SKIP_OLLAMA
- Lines 740+: Testing and summary sections adjust output accordingly

## Benefits

- **Faster Installation**: Skips Docker image downloads and container setup
- **Lower Resource Usage**: No background AI containers consuming memory/CPU
- **Flexibility**: Users can choose their preferred AI providers
- **Compatibility**: Works in environments without Docker access

## Migration

Users can always add Ollama later by:

1. Running the full setup script without SKIP_OLLAMA
2. Manually setting up Ollama Docker containers
3. Updating Fabric configuration to use local models

Date: May 30, 2025
Version: Compatible with shell repository setup.sh v2.x

## Implementation Status

✅ **COMPLETED** - The SKIP_OLLAMA feature is fully implemented and functional.

### What's Implemented:

1. **Core Logic**: Conditional wrapper around Ollama Docker installation (lines 373-523)
2. **Fabric Configuration**: Conditional setup for external AI providers vs. Ollama  
3. **Testing Section**: Conditional testing based on SKIP_OLLAMA setting (lines 752-796)
4. **Post-Installation Instructions**: Different guidance for external AI provider mode
5. **Convenience Script**: `setup-no-ollama.sh` for easy access
6. **Documentation**: This comprehensive guide

### Files Modified:

- `setup/setup.sh`: Main implementation with conditional logic
- `setup-no-ollama.sh`: Convenience script (NEW)
- `skip_ollama.patch`: Documentation (NEW)

### Testing Status:

- ✅ Syntax validation passed
- ✅ Conditional logic implemented
- ⏳ End-to-end testing recommended

The implementation is complete and ready for use.
