Lol, even the open source LLM projects are banning vibe coded contributions: https://github.com/ggml-org/llama.cpp/blob/master/AGENTS.md
They had previously had a policy of "all AI assisted contributions need to be human reviewed before submitting them", but got too many people breaking that rule and submitting fully vibe coded contributions, and even trying to use their chatbots to answer questions about the PRs, so are now actively using the AGENTS.md file to instruct the chatbots to not write code for them and warn them about the policy.
