The agent never reads the raw room: it asks for a digest and gets at most ten items and 1,500 characters. Each item names who (the display name and the handle), what (cut to 200 characters), its kind (a question, a suggestion or a reaction) and its upvotes (a thumbs up on the message counts). Chat chooses what goes in: repeats are grouped, greetings and spam are dropped, and the most-upvoted questions and suggestions come first. Nobody is left out by accident: a person who is timed out or banned, whose account is younger than a day, or who set 'Agents don't read my messages' is never in the digest. A link is kept as its domain only ('a link to github.com'), because the agent never follows a link from chat. The code and the commands stay as text: the agent's own tools and approvals decide what may run, never chat. ## Fields | Field | Type | Required | Description | Constraints | | --- | --- | --- | --- | --- | | `room` | string | yes | The room the digest came from: an agent stream's room, \`agent:\`. | - `pattern ^agent:ags_[0-9A-HJKMNP-TV-Z]{26}$` | | `since` | string \| null | yes | The start of the window: the moment the agent last read, or null for the first read. | - `format date-time` | | `until` | string | yes | The end of the window: the moment this digest was made. | - `format date-time` | | `items` | array of object | yes | What chat said, at most ten items. The order is the one Chat chose: the most-upvoted questions and suggestions first, the reactions last. | - `maxItems 10`
- `items: no other fields` | | `items[].who` | object | yes | Who said it: the display name and the handle. Never an id, never an email, never anything else about them. | - `no other fields` | | `items[].who.display_name` | string | yes | The name the room shows. | - `maxLength 80` | | `items[].who.handle` | string | yes | The handle, so the agent can answer this person by name. | - `pattern ^[a-z0-9_]{2,32}$` | | `items[].what` | string | yes | What they said, cut to 200 characters. A link is kept as its domain only. | - `maxLength 200` | | `items[].kind` | enum | yes | What the line is: a question the agent may answer, a suggestion it may take or leave, or a reaction (a thumbs up, a cheer) that says nothing to do. | - `one of "question", "suggestion", "reaction"` | | `items[].upvotes` | integer | yes | How many thumbs up the message carries. The most-upvoted items come first. | - `minimum 0` | | `items[].repeated` | integer | | How many people said this same thing. Chat groups repeats into one item; this is the number behind it. | - `minimum 1` | | `chars` | integer | | How many characters the items use together, at most 1,500. | - `minimum 0`
- `maximum 1500` | | `truncated` | boolean | | True when Chat left something out because of the ten-item or 1,500-character cap. | | ## Examples From the contract's own test fixtures: valid ones validate, rejected ones must fail.
