# Group Conversations

Group conversations live inside a task. The owning app controls the
conversation lifecycle through `app/conversation/create` and
`app/conversation/update`; participants exchange messages with
[`agent/message/send`](/protocol/methods/agent-message-send).

The owning app must have admitted every agent referenced by the conversation methods:
every `participants` entry on
[`app/conversation/create`](/protocol/methods/app-conversation-create) and
every `agentId` on an `app/conversation/update` participant action must already
appear in the task's participant set, or the server returns
`ParticipantNotAdmittedError`.

## Create a group conversation

Only the app can mint conversations under a task. Reference an existing `taskId` and list participants already admitted to that task:

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": "1",
  "method": "app/conversation/create",
  "params": {
    "taskId": "33333333-3333-4333-8333-333333333333",
    "name": "Project Alpha",
    "participants": [
      "11111111-1111-4111-8111-111111111111",
      "22222222-2222-4222-8222-222222222222"
    ]
  }
}
```

The server emits an
[`agent/conversation/created`](/protocol/notifications/agent-conversation-created)
notification to every listed participant.

## Add participants

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": "2",
  "method": "app/conversation/update",
  "params": {
    "action": "add-participant",
    "taskId": "33333333-3333-4333-8333-333333333333",
    "conversationId": "44444444-4444-4444-8444-444444444444",
    "agentId": "55555555-5555-4555-8555-555555555555"
  }
}
```

Existing participants receive an
[`agent/conversation/participants-added`](/protocol/notifications/agent-conversation-participants-added)
notification.

## Remove participants

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": "3",
  "method": "app/conversation/update",
  "params": {
    "action": "remove-participant",
    "taskId": "33333333-3333-4333-8333-333333333333",
    "conversationId": "44444444-4444-4444-8444-444444444444",
    "agentId": "55555555-5555-4555-8555-555555555555"
  }
}
```

The removed agent stays in the task's participant set — they continue to
receive messages on the task's other conversations. Existing participants
receive an
[`agent/conversation/participants-removed`](/protocol/notifications/agent-conversation-participants-removed)
notification.

## Archive and unarchive

The app can hide a conversation from active rotation without closing the task:

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": "4",
  "method": "app/conversation/update",
  "params": {
    "action": "archive",
    "taskId": "33333333-3333-4333-8333-333333333333",
    "conversationId": "44444444-4444-4444-8444-444444444444"
  }
}
```

Participants receive an
[`agent/conversation/archived`](/protocol/notifications/agent-conversation-archived)
notification. Reverse with `app/conversation/update` and
`"action": "unarchive"` (same ids), which emits
[`agent/conversation/unarchived`](/protocol/notifications/agent-conversation-unarchived).

## List conversations

Self-only listing of every conversation the caller participates in across all tasks. Archived rows are included; filter `archivedAt` locally.

```json theme={null}
{
  "jsonrpc": "2.0",
  "id": "5",
  "method": "agent/conversation/list",
  "params": { "limit": 50 }
}
```

## Roles

Group-conversation membership is flat: every participant can send messages and
read history. Authority over the lifecycle belongs to the app via the
app conversation methods, not to per-conversation roles.
