Automated AtCoder Contest Prep Alerts
Every Monday, WebRun opens AtCoder, checks the upcoming contest schedule and each club member's rating change from the last contest, creates a Trello prep card for the next contest, and drafts a WhatsApp alert with the schedule and standings for the club lead to review and send.

Questions, answered
Will it message the club group without the lead?
No. The alert is always drafted and left unsent. WebRun never sends a WhatsApp message on its own, the club lead approves and sends it.
Does it register anyone for a contest?
No. It only reads the public contest schedule and reports it. Registering for AtCoder contests is always done by each member.
How does it read rating changes?
From each member's public AtCoder profile after a contest is rated, so the numbers reflect real results, not estimates.
