# Calendar Integration -- Technical Specification

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

## Functional Requirements

### FR-1: Calendar Provider Interface
- `CalendarProvider` shall define abstract methods: `list_events`, `create_event`, `get_event`, `delete_event`, `update_event`.
- All providers shall work with `CalendarEvent` data models.

### FR-2: Google Calendar Provider
- `GoogleCalendar` shall implement `CalendarProvider` using the Google Calendar API.
- Shall support OAuth2 credential-based authentication.
- Gracefully unavailable when `google-api-python-client` is not installed.

### FR-3: Event Model
- `CalendarEvent` shall include: title, start, end, description, attendees, location, and metadata.

## Interface Contracts

```python
def calendar_list_events(start: str, end: str) -> dict
def calendar_create_event(title: str, start: str, end: str, description: str = "") -> dict
def calendar_get_event(event_id: str) -> dict
def calendar_delete_event(event_id: str) -> dict
def calendar_update_event(event_id: str, updates: dict) -> dict
```
