hi, one of the folks behind this. Back in May, @sqs acquired the domain and launched the website above, committing to relocate if the agents.md domain could be acquired. In July, I put out [1] RFC 9999 as a call to the industry that we need to fix this mess. Shortly afterwards OpenAI was able to obtain the domain and thus we (Amp) followed through on the commitment and worked with other vendors to move from AGENT.md to AGENTS.md.

This seems much more insightful than the website in the OP. Thanks!
