Requirements Document

Introduction

This feature enables automatic synchronization of calendar entries between two different calendar accounts using AppleScript. The system will copy events from a source calendar account to a destination calendar account, maintaining event details while avoiding duplicates and providing configurable sync options.

Requirements

Requirement 1

User Story: As a user with multiple calendar accounts, I want to sync events from one account to another, so that I can maintain consistent scheduling across different calendar systems.

Acceptance Criteria

1. WHEN the sync script is executed THEN the system SHALL read all events from the specified source calendar
2. WHEN events are found in the source calendar THEN the system SHALL copy them to the specified destination calendar
3. WHEN copying events THEN the system SHALL preserve event title, date, time, duration, and description
4. IF an event already exists in the destination calendar THEN the system SHALL skip creating a duplicate

Requirement 2

User Story: As a user, I want to configure which calendars to sync between, so that I can control the data flow between my accounts.

Acceptance Criteria

1. WHEN configuring the sync THEN the system SHALL allow selection of source calendar account and specific calendar
2. WHEN configuring the sync THEN the system SHALL allow selection of destination calendar account and specific calendar
3. WHEN invalid calendar names are provided THEN the system SHALL display an error message and exit gracefully
4. WHEN calendar accounts are not accessible THEN the system SHALL provide clear error messaging

Requirement 3

User Story: As a user, I want the sync to focus on today's events only, so that I maintain current day synchronization without overwhelming the destination calendar.

Acceptance Criteria

1. WHEN the sync runs THEN the system SHALL only process events occurring on the current day
2. WHEN determining current day THEN the system SHALL use the local system date
3. WHEN events span multiple days THEN the system SHALL include events that start or occur on the current day
4. WHEN no events exist for the current day THEN the system SHALL complete successfully with appropriate messaging

Requirement 4

User Story: As a user, I want the destination calendar to mirror the source calendar for the current day, so that removed events are also cleaned up automatically.

Acceptance Criteria

1. WHEN checking for duplicates THEN the system SHALL compare event title, start date, and start time
2. WHEN a matching event is found in the destination THEN the system SHALL skip creating the duplicate
3. WHEN an event exists in the destination but not in the source for the current day THEN the system SHALL remove it from the destination
4. WHEN an event has been modified in the source THEN the system SHALL update the corresponding event in the destination

Requirement 5

User Story: As a user, I want to see progress and results of the sync operation, so that I can verify the synchronization was successful.

Acceptance Criteria

1. WHEN the sync starts THEN the system SHALL display the source and destination calendar information
2. WHEN processing events THEN the system SHALL show progress indicators for each event processed
3. WHEN the sync completes THEN the system SHALL display a summary of events copied, skipped, and any errors
4. WHEN errors occur THEN the system SHALL log detailed error information for troubleshooting

Requirement 6

User Story: As a user, I want the sync to handle different event types and properties, so that all my calendar data is accurately transferred.

Acceptance Criteria

1. WHEN syncing events THEN the system SHALL handle all-day events correctly
2. WHEN syncing events THEN the system SHALL preserve recurring event patterns when possible
3. WHEN syncing events THEN the system SHALL handle events with attendees and meeting details
4. WHEN event properties cannot be transferred THEN the system SHALL log which properties were skipped
