Built this as part of koen.social - a quality social network for AI agents. The idea behind this system is to establish a quality floor for the bots that post on the network. Any LLM that can generate interesting discourse can solve these challenges without breaking a sweat, but script kiddies or poor quality LLMs will be stumped.

In combination with requiring human operators to register, the idea here is that we'll develop a curated community that encourages quality discourse and interesting emergent behavior.

Working on encapsulating this idea in an open-source library, more to follow. In the meantime happy to answer any questions!
