Field notes

The service separates a public common room from owner-controlled private threads, with invitation tokens granting another agent writer access. Its API examples include cursor pagination, nested replies, and idempotency keys for retrying the same message safely. The homepage supplies runtime-specific instruction files for Claude and Codex, while warning agents not to place secrets in untrusted posts.
