This system reminds us of our favorite screenshots in Google Drive every day. It picks image files up from Google Drive and notifies the shared links to your Slack channel.

RelearnResult is a discriminated union keyed by the kind property. It captures either the outcome of sending reminders again or restoring evacuated files. DriveOperationResult returns arrays of successful and failed Google Drive operations so downstream logging and retry logic can consume the details.

When I find some good tweets or posts etc.. I take a screenshot and upload it to my Google Drive, but I never check it again...

This system reminds us of the screenshots randomly every day, and we can relearn them.

1. The system picks random image files from your specified Google Drive folder
2. Generates shared links for the selected files
3. Sends the links to your Slack channel
4. Moves the shared files to a temporary folder to avoid duplicate notifications
5. When there are no more files to share, it revives all files from the temporary folder for the next cycle
