What Codeforces does
Competitive programming runs on a schedule, and missing the start of a round is the most common way to lose a rating point you did not have to lose. The bot's job is that schedule: it tells you when the next Codeforces contest begins and brings platform updates into the chat you already read.
It is a fan project — the author leaves a contact in the bot's own description rather than claiming to speak for the site — so treat it as a convenience layer over a public schedule. For the contest itself, the site remains the only source of truth.
How to start
- Open @codeforces_bot and press Start
- Ask about the upcoming round
- Check the site before the contest itself

FAQ
Is it the official Codeforces bot?
No. The bot's own description gives an author's contact, so it is a fan project over public data.
Can it show my rating?
Treat the schedule as what it reliably does; anything account-specific should be checked on the site.
