Your agent wrote it. Did you read it?

antiBug plants one subtle logic bug in code you just shipped. Find the line before the clock runs away.

Public repos only. We drill the JS/TS file with the most added lines in the commit you pick, skipping tests when there's other code.

How it works

  1. 1
    Pick code

    A commit your agent just wrote, or a pasted snippet.

  2. 2
    We plant one bug

    A realistic logic slip in the changed lines. It still compiles.

  3. 3
    Find the line

    Against the clock. A wrong click costs 10s, a hint 15s.
