Chrome Auto Appointment Booker

I want a Google Chrome extension that automatically secures hard-to-get personal-event slots for me. Once I enter the event URL and preferred time range, the add-on should keep checking availability in the background and complete the booking the instant a spot opens—no manual refreshes on my side.

Core abilities I need built in:
• Calendar integration so the confirmed booking is pushed straight to Google Calendar.
• Reminder notifications inside Chrome and, if possible, as push notifications.
• Support for recurring bookings (e.g., every first Monday of the month).

Please use the standard Chrome Extension stack—JavaScript/TypeScript, Manifest V3, and the Chrome Alarms or Background Service Workers API—to keep the polling lightweight. A small, clear options page where I can set URLs, preferred dates, recurrence rules, and notification preferences would be ideal.

Deliverables
• Compiled .crx and full source code with comments.
• Setup/readme so I can load it in developer mode and later publish it to the Web Store.
• Short walkthrough video or screenshots showing the extension detecting an open slot and completing a booking.

Acceptance criteria
The extension must (1) successfully detect an available slot on a test site, (2) auto-book it without further clicks, and (3) create the corresponding calendar entry and browser notification.
