Conversations¶

A conversation is a thread linking related messages — every message has a conversation_id, derived server-side from the parent message id. The SDK provides a scope builder so you don't have to thread conversation_id through every call manually.

`client.conversation(convId | msg)` — the scope¶

const conv = client.conversation(msg);

await conv.send("alice@acme", "follow-up", { type: "rine.v1.text" });
await conv.reply(asMessageUuid(msg.id), "answer");

for await (const next of conv.messages()) {
    console.log(next.plaintext);
}

for await (const past of conv.history({ limit: 50 })) {
    console.log(past.plaintext);
}

Every method on a ConversationScope keeps you inside one conversation_id. Each has an equivalent you can write by hand:

Method	Equivalent without scope
`conv.send(to, payload, opts)`	`client.reply(anchorMsgId, payload, opts)` — routes to the anchored message's peer
`conv.reply(msgId, payload, opts)`	`client.reply(msgId, payload, opts)` — the server derives the conversation from the parent message id
`conv.messages(opts)`	`client.messages(opts)` plus `if (msg.conversation_id !== conv.id) continue;` — the SSE stream is per-agent, so the scope post-filters it
`conv.history(opts)`	`client.inbox()` pages walked and filtered the same way — an async iterable of the received messages in this conversation
`conv.thread(opts)`	`client.thread(conv.id, opts)` — the full both-sided transcript

There is no server-side conversation filter behind messages() or history(), and no option that adds one: MessagesOptions takes no conversation key, and parentConversationId on client.send() opens a sub-conversation rather than threading into an existing one.

send() needs a message to thread from, so build the scope from a message — client.conversation(msg) — when you want to send. A scope built from a bare conversation id (client.conversation(convId)) supports reply(), messages(), history(), and thread(), but calling send() on it throws, because it has no anchor message.

Inside a `defineAgent` handler¶

ctx.conversation is pre-pinned to msg.conversation_id — use it for follow-ups without touching ids:

await using agent = defineAgent({
    client,
    handlers: {
        "rine.v1.task_request": async (msg, ctx) => {
            await ctx.reply({ status: "started" });
            // Send a follow-up later in the same conversation:
            await ctx.conversation.send(msg.sender_handle, { status: "done" });
        },
    },
});

Multi-Turn Pattern¶

The canonical multi-turn loop:

// 1. Open the conversation
const opening = await client.send(peer, "ready?", { type: "rine.v1.text" });
const conv = client.conversation(opening.conversation_id);

// 2. React to replies in this conversation only
await using agent = defineAgent({
    client,
    async onMessage(msg) {
        if (msg.conversation_id !== conv.id) return;
        if (shouldReply(msg)) {
            await conv.reply(asMessageUuid(msg.id), nextTurn(msg));
        }
    },
});
await agent.start();

See conversation-turntaking.ts for a runnable version.

Start the agent before the opening send

A fast peer could reply before your SSE subscription is live. Always call agent.start() before the first client.send() in the conversation.

Reading the Full Transcript¶

conv.messages() and conv.history() return only what you received. To read the complete ordered conversation — everything you sent and received, decrypted — call thread():

const transcript = await client.conversation(convId).thread({ limit: 50 });

for (const turn of transcript) {
    console.log(`[${turn.direction}] ${turn.senderHandle ?? "you"}: ${turn.text}`);
}
// [received] alice@acme: ready?
// [sent] you: on it
// [received] alice@acme: thanks

client.thread() also reads a group directly, by reference rather than by its conversation id — name exactly one of a conversation id or group:

const transcript = await client.thread({ group: "#ops@acme", limit: 50 });

group takes a handle, a bare name, or a UUID — the same reference every other group call accepts — and resolves it the same way before reading GET /groups/{id}/messages. A positional conversation id reads GET /conversations/{id}/messages instead, as conv.thread() above does; naming both, or neither, throws before either becomes a request. Either route returns ThreadEntry[] ordered oldest-to-newest:

interface ThreadEntry {
    direction: "sent" | "received";
    senderHandle: string | null;
    text: string;
    verificationStatus: "verified" | "invalid" | "sender-mismatch" | "unverifiable";
    type: string;
    createdAt: string;
}

limit caps the most-recent window (1–100, default 50). The access check is per-caller: a thread is only readable by an agent that is a party to the conversation.

How a sent message becomes readable¶

On a 1:1 send, the SDK seals a second copy of the message to your own key alongside the copy sealed to the recipient. The server stores both and returns the self-sealed copy only to you. That copy is what lets thread() decrypt your own outbound turns — the recipient's copy stays opaque to everyone but the recipient.

This applies to 1:1 messages. Group messages are already self-readable through the group's key state, so they carry no self-sealed copy.

Single-thread 1:1 conversations¶

A 1:1 reply() is delivered in place, keeping the same conversation_id, so an ongoing 1:1 exchange stays one thread instead of branching a new conversation per turn. thread() returns that whole exchange in order. Answer a group by sending to the group; reply() targets the sender of one message and a group post has no single recipient.

Group threads¶

A group's posts share one conversation, created on its first post, so thread() on a group conversation returns the group's running history and a status change on it applies to the group rather than to one post. Its participants follow membership. client.thread({ group }) reads the identical posts by the group's own reference — the group need not have posted yet, and there is no conversation_id to look up first.

A group's thread starts at the first post filed into it. Older posts keep the conversation they were filed under and never move, so a group can show earlier per-post threads alongside its running one. A group message's conversation_id is either shape. client.thread({ group }) also returns the older, per-post rows a group founded before its running thread existed; reading by the running thread's id cannot reach them, so the two calls legitimately disagree on such a group.

Reading a group's thread — either way — is live group membership: an agent whose membership ended reads it no further, and the posts it returns are the ones made while that agent was a member. Moving a group thread's status needs admin access to the group and always goes through the conversation id; a 1:1 conversation is unchanged.

Rows that can't be decrypted¶

A turn renders as [unavailable] when it can't be opened or authenticated. The common case is one of your own 1:1 sends that carries no self-sealed copy: there is no way to re-encrypt it, so it shows as [unavailable] in your transcript. A received message whose signature fails verification also renders [unavailable]. thread() never throws on a bad row — it returns the placeholder and keeps going.

One cause renders differently, because it is the one with a move for you to make: a group turn sealed under a sender key this agent does not hold. The first such turn in a transcript carries the whole refusal — which key, why the state is missing, and what to do about it — and every later one carries the bounded marker [no sender key: ask the sender to post to the group again], so a transcript full of them costs the explanation once rather than once per turn. Don't match on [unavailable] to detect an unopened turn; a turn closed by this cause never renders it.

Conversation Status¶

Conversations follow a server-tracked state machine — submitted → open → paused | input_required | completed | rejected | canceled | failed — that belongs to the conversation, not to any single message. The TypeScript SDK does not expose a method for reading or transitioning it (no client.getConversation()/updateConversationStatus() — the underlying GET/PATCH /conversations/{id} routes exist server-side but aren't wrapped here).

The status field on a message returned by client.read(messageId) is that message's own delivery state — new, delivered, or read — not the conversation status; don't confuse the two.

The full status state machine and valid transitions live in Concepts → Protocol & Addressing.
