Requirements Document

Introduction

This feature adds optional scheduling capabilities to the Shopify Price Updater, allowing users to schedule price updates or rollbacks to execute at specific future times. This enables store owners to set up promotional campaigns in advance without needing to manually execute the script at the exact moment the sale should begin or end.

Requirements

Requirement 1

User Story: As a store owner, I want to schedule a price update to run at a specific date and time, so that I can set up promotional campaigns in advance without staying up late or being available at the exact moment.

Acceptance Criteria

1. WHEN a user sets a SCHEDULED_EXECUTION_TIME environment variable THEN the system SHALL validate the datetime format and schedule the operation accordingly
2. WHEN the scheduled time is reached THEN the system SHALL execute the configured price update or rollback operation automatically
3. WHEN no SCHEDULED_EXECUTION_TIME is provided THEN the system SHALL execute immediately as it currently does
4. WHEN an invalid datetime format is provided THEN the system SHALL display a clear error message and exit without scheduling

Requirement 2

User Story: As a store owner, I want to see confirmation that my price update has been scheduled, so that I can be confident the operation will run at the correct time.

Acceptance Criteria

1. WHEN a scheduled operation is configured THEN the system SHALL display the scheduled execution time in a human-readable format
2. WHEN a scheduled operation is waiting THEN the system SHALL show a countdown or status message indicating when it will execute
3. WHEN the scheduled time arrives THEN the system SHALL log the start of the scheduled operation with a timestamp

Requirement 3

User Story: As a store owner, I want to be able to cancel a scheduled operation before it executes, so that I can change my mind or correct mistakes.

Acceptance Criteria

1. WHEN a scheduled operation is waiting THEN the system SHALL respond to standard interrupt signals (Ctrl+C) to cancel the operation
2. WHEN a scheduled operation is cancelled THEN the system SHALL display a confirmation message and exit cleanly
3. WHEN a scheduled operation is cancelled THEN the system SHALL NOT execute any price updates

Requirement 4

User Story: As a store owner, I want flexible datetime input options, so that I can easily specify when my sale should start or end.

Acceptance Criteria

1. WHEN specifying a scheduled time THEN the system SHALL accept ISO 8601 datetime format (YYYY-MM-DDTHH:MM:SS)
2. WHEN specifying a scheduled time THEN the system SHALL accept timezone information or default to the system timezone
3. WHEN the scheduled time is in the past THEN the system SHALL display an error and not schedule the operation
4. WHEN the scheduled time is more than 7 days in the future THEN the system SHALL display a warning but still schedule the operation

Requirement 5

User Story: As a store owner, I want the scheduled operation to handle errors gracefully, so that temporary issues don't prevent my promotional campaign from running.

Acceptance Criteria

1. WHEN the scheduled time arrives AND there are network connectivity issues THEN the system SHALL retry the operation with exponential backoff
2. WHEN the scheduled operation encounters API rate limits THEN the system SHALL handle them using the existing retry logic
3. WHEN the scheduled operation fails after all retries THEN the system SHALL log detailed error information for troubleshooting
4. WHEN the scheduled operation completes successfully THEN the system SHALL log the completion status and summary
