Public demo: the standing room¶

A public demo host keeps one room open for anyone who arrives. The host forms the room itself from a fixed sentence, binds it to a pack, and owns it with its own seat. Visitors join it by its code. Nobody else starts rooms on that host. When the room's time is up it ends, and a new one forms.

This page shows how to run it with the World Tour pack, what visitors can do, and the guards that keep the owner's model bill bounded.

Run it¶

Put the model keys in the environment, then start the host with the pack and the standing room settings:

export COALITIONKIT_META_API_KEY=...
export COALITIONKIT_STANDING_ROOM_GOAL="We need a must-see place in each of our cities, the hour that fits everyone, who shows what in order, and a tour poster for our one-hour virtual world tour"
export COALITIONKIT_STANDING_ROOM_PACK=world-tour
export COALITIONKIT_STANDING_ROOM_MINUTES=15
export COALITIONKIT_ROOM_BUDGET_USD=0.50
export COALITIONKIT_SEARCH_PROVIDER=meta
coalitionkit up --port 8000 --data-dir ./public-host --pack packs/world-tour \
  --public-url https://rooms.example

--public-url is the address people reach, for example a cloudflared tunnel --url http://127.0.0.1:8000 address (see Phone inputs for the tunnel). Within a few seconds the host prints Standing room formed: ABC-DEFG, and the landing page shows the room with its code and seats.

The settings¶

Setting	Default	Meaning
`COALITIONKIT_STANDING_ROOM_GOAL`	unset	The sentence the room forms from. Setting it turns the standing room on
`COALITIONKIT_STANDING_ROOM_PACK`	unset	The installed pack the room is bound to, by name. The host refuses to form a room when it is not installed
`COALITIONKIT_STANDING_ROOM_MINUTES`	`15`	How long a room lives, from forming to its end
`COALITIONKIT_STANDING_ROOM_GATHER_MINUTES`	`5`	How long the room waits for people before it begins. It begins only when at least one visitor sits beside the host's seat
`COALITIONKIT_STANDING_ROOM_SEATS`	`12`	The seats in each room. The host's seat takes the pack's chartering role, every other seat its first role that may offer
`COALITIONKIT_ROOM_BUDGET_USD`	unset	The most the models may cost one room, in US dollars. Applies to every room on the host

All of them are in the settings reference.

What visitors can do¶

See the room. The landing page reads GET /v1/standing and shows the goal, the seats taken, the minutes left and the code. It never shows a token.
Take a seat. Take a seat joins by the code, the same way as any room's code. A visitor gets a hosted agent, or brings their own over MCP or A2A with the code.
Answer, talk, hold. Inside, the room runs as any other: the brief, the offers, the talk, the plans, each person's press-and-hold, the results.

Visitors cannot start a room. While the standing room is on, POST /v1/genesis/start needs a start code and POST /v1/genesis/draft needs the admin token, so the landing page hides the sentence box.

The clock¶

Forms. When no standing room is open, the host creates one from the sentence. Its owner is the host's own hosted seat. The owner's token is written to standing-room.json in the data folder, beside admin.token; treat it as a password.
Begins. After the gather minutes, with at least one visitor seated, the host begins the room: the door closes and the people seated decide. The host's own seat has no person to answer its brief, so its brief is closed.
Ends. At its time the host dissolves the room with the reason completed. Vaults are erased and lessons written, as for any room.
Forms again. The next step forms a new room with a new code.

The guards¶

Budget per room. Before each model call of a room (a hosted agent's question or offer, a made result, a picture, a web search), the host checks the room's metered spend against COALITIONKIT_ROOM_BUDGET_USD. Past it, nothing is sent, the rules answer instead, and the Table shows one line: Model budget reached. The Steward's reviews are not capped, because they guard what the room shows.
Time. No room outlives its minutes, so an abandoned room costs nothing after its end.
No new rooms. Only the host forms rooms. A visitor's sentence never reaches a model.
Search stays public. Agents search the web only with public words: the goal, the need and, for a pack's public question, the answer the seat published. A street address or anything a person said privately stops the query before it leaves the host. See Web search.

Cost¶

Each room is paid by the host's owner. Read the room's spend on the Table's cost line, or from spent_usd in GET /v1/standing, and set the budget from what one room should cost. A whole scripted room with three hosted seats costs about $0.17.
