# vs-code - Functional Specification

**Version**: v1.1.9 | **Status**: Active | **Last Updated**: March 2026

## Purpose

Integration with Visual Studio Code, providing programmatic access to the Extension API, workspace management, task automation, and debugging capabilities.

## Design Principles

### Modularity

- Extension management separated from workspace operations
- Debug control as independent component
- Task automation modular

### Functionality

- Real working integration with VS Code
- Full coverage of available APIs
- Production-ready implementation

## Functional Requirements

### Command Execution

1. List available commands
2. Execute commands with arguments
3. Handle command responses
4. Track command history

### Workspace Management

1. Open/close workspaces
2. Manage workspace settings
3. Handle multi-root workspaces
4. Query workspace state

### Extension Control

1. List installed extensions
2. Enable/disable extensions
3. Query extension state
4. Extension recommendations

### Debug Integration

1. Start/stop debug sessions
2. Manage breakpoints
3. Inspect variables
4. Step through code

## Interface Contracts

### VSCodeClient

```python
class VSCodeClient(IDEClient):
    def connect(self) -> bool: ...
    def disconnect(self) -> None: ...
    def get_capabilities(self) -> dict: ...
    def list_extensions(self) -> List[dict]: ...
    def list_commands(self) -> List[str]: ...
    def start_debug(self, config: dict) -> bool: ...
    def stop_debug(self) -> bool: ...
```

## Detailed Architecture and Implementation

### Design Principles

1. **Strict Modularity**: Each component is isolated and communicates via well-defined APIs.
2. **Performance Optimization**: Implementation leverages lazy loading and intelligent caching to minimize resource overhead.
3. **Error Resilience**: Robust exception handling ensures system stability even under unexpected conditions.
4. **Extensibility**: The architecture is designed to accommodate future enhancements without breaking existing contracts.

### Technical Implementation

The codebase utilizes modern Python features (version 3.10+) to provide a clean, type-safe API. Interaction patterns are documented in the corresponding `AGENTS.md` and `SPEC.md` files, ensuring that both human developers and automated agents can effectively utilize these capabilities.
