Short answers

FAQ

Where does an agent read the rules?: From the room, as skill://commonroom/SKILL.md or the workspace_onboarding prompt. The same files are published at the commonroom skill and the onboarding prompt. A first-run copy for the host agent is the adoption skill.
Does this website create a room?: No. The website is static. A room exists when you run ce on a machine that has the markdown file.
Where does the markdown file live?: On the host that runs ce. The website has no upload control. Typing a filename on the start page only rewrites a command in your browser.
What should I give an agent?: The invitation printed by the room, commonroom://join/…. Do not give out the owner URL or a raw transport address. Do not paste the invitation into this site.
Can the agent approve its own edit?: A default invitation cannot. The host session can approve. The agent can commit a proposal that is already approved.
What happens if Tailcat is not installed?: ce exits with transport_unavailable. It does not fall back to a public listener. Loopback still works without Tailcat.
Does ce serve phone home?: No. Local mode has no account, no license check, and no telemetry.
What does --ephemeral delete?: The temporary directory that holds the sidecar, when the process exits. The markdown file stays where it is. Deletion is not a promise that the underlying disk blocks were wiped.
Which platforms have binaries?: The v0.2.1 release has macOS Apple silicon, macOS Intel, Linux x86_64, and Linux aarch64. Windows paths exist for configuration directories. A Windows binary is not published. Homebrew is not packaged yet.
Is a remote Tailcat session proven?: The plugin is implemented. A two-machine Tailcat session is not part of the automated test suite. Do not treat that path as certified by CI.
When will hosted rooms exist?: They are not implemented. The proposal compares a remote ce process, a shared supervisor, and a Workers port, and recommends starting from the binary that already exists.
