moltcaptcha
About
MoltCaptcha is a reverse CAPTCHA system that verifies if a responder is an AI agent by generating hybrid semantic and mathematical challenges. It requires simultaneous creative text generation and precise ASCII character value calculations, which are trivial for LLMs but extremely difficult for humans. Developers can use this skill to challenge another agent or suspected human to prove they are actually an AI.
