-## Features -- **Multi-Provider Support**: Compatible with both OpenAI GPT-4 and Anthropic Claude APIs -- **Natural Language Processing**: Converts user intent into executable system commands -- **Command Validation**: Built-in safety mechanisms to prevent destructive operations -- **Flexible API**: Simple interface with context-aware parsing capabilities -- **Comprehensive Testing**: Unit test suite with 80%+ coverage - -## Architecture - -### Core Components -1. **CommandInterpreter**: Main class handling LLM interactions and command generation -2. **APIProvider**: Enum for supported LLM providers (OpenAI, Claude) -3. **Validation Layer**: Safety checks for dangerous command patterns - -### Key Methods -- `parse(user_input, validate)`: Convert natural language to bash commands -- `parse_with_context(user_input, system_info, validate)`: Context-aware command generation -- `_validate_commands(commands)`: Filter dangerous command patterns -- `_call_openai(user_input)`: OpenAI API integration -- `_call_claude(user_input)`: Claude API integration - -## Usage Examples - -### Basic Usage -```python -from LLM import CommandInterpreter - -interpreter = CommandInterpreter(api_key="your-api-key", provider="openai") -commands = interpreter.parse("install docker with nvidia support") -# Returns: ["sudo apt update", "sudo apt install -y docker.io", "sudo apt install -y nvidia-docker2", "sudo systemctl restart docker"] -``` - -### Claude Provider -```python -interpreter = CommandInterpreter(api_key="your-api-key", provider="claude") -commands = interpreter.parse("update system packages") -``` - -### Context-Aware Parsing -```python -system_info = {"os": "ubuntu", "version": "22.04"} -commands = interpreter.parse_with_context("install nginx", system_info=system_info) -``` - -### Custom Model -```python -interpreter = CommandInterpreter( - api_key="your-api-key", - provider="openai", - model="gpt-4-turbo" -) -``` - -## Installation - -```bash -pip install -r requirements.txt -``` - -## Testing - -```bash -python -m unittest test_interpreter.py -``` - -## Safety Features - -The module includes validation to prevent execution of dangerous commands: -- `rm -rf /` patterns -- Disk formatting operations (`mkfs.`, `dd if=`) -- Direct disk writes (`> /dev/sda`) -- Fork bombs - -## API Response Format - -LLMs are prompted to return responses in structured JSON format: -```json -{ - "commands": ["command1", "command2", "command3"] -} -``` - -## Error Handling - -- **APIError**: Raised when LLM API calls fail -- **ValueError**: Raised for invalid input or unparseable responses -- **ImportError**: Raised when required packages are not installed - -## Supported Scenarios - -The system handles 20+ common installation and configuration scenarios including: -- Package installation (Docker, Nginx, PostgreSQL, etc.) -- System updates and upgrades -- Service management -- User and permission management -- Network configuration -- File system operations - -## Technical Specifications - -- **Language**: Python 3.8+ -- **Dependencies**: openai>=1.0.0, anthropic>=0.18.0 -- **Test Coverage**: 80%+ -- **Default Models**: GPT-4 (OpenAI), Claude-3.5-Sonnet (Anthropic) -- **Temperature**: 0.3 (for consistent command generation) -- **Max Tokens**: 1000 - -## Future Enhancements - -- Support for additional LLM providers -- Enhanced command validation with sandboxing -- Command execution monitoring -- Multi-language support for non-bash shells -- Caching layer for common requests diff --git a/LLM/__init__.py b/LLM/__init__.py deleted file mode 100644 index 7b3bbb2..0000000 --- a/LLM/__init__.py +++ /dev/null @@ -1,3 +0,0 @@ -from .interpreter import CommandInterpreter -
