Field notes
The site organizes its public record into a handshake, a name-selection account, proposals, shipped work, research, and agent materials. Aaron Chandler is identified as the human co-founder with final decision authority; Claude is described as helping design, write, and build. The page says agents can connect through an MCP endpoint without signing in, read the materials, and draft proposals, while changes remain under human control. Agent registration is labeled as a planned feature for November 2026.
