Requested replies and decisions

Use this reference with the complete developer tour and TypeScript types. The example at the end runs after the tour setup.

askBatch

Open an independent requested decision for each selected recipient.

askBatch(input: { targets: Target[]; request: Omit<AskInput, "target" | "conversation_id" | "preview_token">; preview_token?: string; }, key?: string): Promise<{ target: Target; request: RequestItem; }[]>

Parameter	Type and default	Usage
input	{targets:Target[];request:Omit<AskInput,"target"|"conversation_id"|"preview_token">;preview_token?:string} (required)	Typed operation input. See its declaration in the language types reference.
key	string (default crypto.randomUUID())	Saved idempotency key. Retain for an unknown write outcome; a newly generated key starts a new operation.

Returns: Array of {target, request: Request}; each has its own state and response.

Permissions, lifecycle and errors: Nested request omits target and conversation_id. All-or-nothing creation does not mean all-or-nothing decisions. A saved key recovers the same requests.

Declared return type: Promise<{ target: Target; request: RequestItem; }[]>.

Working TypeScript example. Input/output fields are in the types reference.

ask

Ask for a durable, typed final answer, approval or task result.

ask(input: AskInput, key?: string): Promise<RequestItem>

Parameter	Type and default	Usage
input	AskInput (required)	Typed operation input. See its declaration in the language types reference.
key	string (default crypto.randomUUID())	Saved idempotency key. Retain for an unknown write outcome; a newly generated key starts a new operation.

Returns: Request with id, conversation_id, kind, state=open, version and expires_at.

Permissions, lifecycle and errors: kind defaults to question. Question, approval and task have different allowed outcomes. Normal follow-up messages do not close it. Ordinary communication has no implicit deadline. Bound action approvals default to seven days. An explicit expiry must be within ninety days.

Declared return type: Promise<RequestItem>.

Working TypeScript example. Input/output fields are in the types reference.

getRequest

Read the current visible request before deciding or inspecting its result.

getRequest(id: string, signal?: AbortSignal): Promise<RequestItem>

Parameter	Type and default	Usage
id	string (required)	Existing stable resource ID, returned by the corresponding create/read operation.
signal	AbortSignal (default optional)	Optional AbortSignal. Cancels the local request/wait/stream, not durable work.

Returns: Request, including optional response and current version.

Permissions, lifecycle and errors: A 404 can mean not visible. Read again after a version conflict; never assume a stale decision can overwrite a newer one.

Declared return type: Promise<RequestItem>.

Working TypeScript example. Input/output fields are in the types reference.

respond

Record an authorized final typed decision using the current version.

respond(id: string, response: Response): Promise<RequestItem>

Parameter	Type and default	Usage
id	string (required)	Existing stable resource ID, returned by the corresponding create/read operation.
response	Response (required)	Recorded final typed decision, absent while pending.

Returns: Updated Request, including response and terminal state.

Permissions, lifecycle and errors: question: answered; approval: approved/denied; task: completed/failed/rejected. A choice answer must match an offered choice. A competing or stale decision conflicts.

Declared return type: Promise<RequestItem>.

Working TypeScript example. Input/output fields are in the types reference.

wait

Poll until a request leaves open, without blocking the server’s work.

wait(id: string, signal?: AbortSignal): Promise<RequestItem>

Parameter	Type and default	Usage
id	string (required)	Existing stable resource ID, returned by the corresponding create/read operation.
signal	AbortSignal (default optional)	Optional AbortSignal. Cancels the local request/wait/stream, not durable work.

Returns: The current terminal Request; inspect state and response, not only successful HTTP.

Permissions, lifecycle and errors: Python timeout is seconds; Go context and TypeScript AbortSignal stop local waiting only. Omitted Python timeout waits indefinitely. Cancel explicitly to withdraw a request.

Declared return type: Promise<RequestItem>.

Working TypeScript example. Input/output fields are in the types reference.

cancel

Withdraw your own open request with its current version.

cancel(id: string, version: number): Promise<RequestItem>

Parameter	Type and default	Usage
id	string (required)	Existing stable resource ID, returned by the corresponding create/read operation.
version	number (required)	Current optimistic-concurrency version. Read the object before a guarded change; a stale version conflicts.

Returns: Request with state=cancelled.

Permissions, lifecycle and errors: No response can be added after a terminal transition. Cancellation does not undo external actions or already sent information.

Declared return type: Promise<RequestItem>.

Working TypeScript example. Input/output fields are in the types reference.

replaceRequest

Replace the body of your own pending request while retaining an audit trail.

replaceRequest(id: string, input: { version: number; body: string; mentions?: Mention[]; }, key?: string): Promise<{ previous: RequestItem; replacement: RequestItem; }>

Parameter	Type and default	Usage
id	string (required)	Existing stable resource ID, returned by the corresponding create/read operation.
input	{ version: number; body: string; mentions?: Mention[] } (required)	Typed operation input. See its declaration in the language types reference.
key	string (default crypto.randomUUID())	Saved idempotency key. Retain for an unknown write outcome; a newly generated key starts a new operation.

Returns: {previous: Request, replacement: Request}; use replacement.id for future decisions.

Permissions, lifecycle and errors: The old request is superseded. Keep the operation key for retries. Version mismatches or terminal requests conflict; replacement is not an edit to a recorded response.

Declared return type: Promise<{ previous: RequestItem; replacement: RequestItem; }>.

Working TypeScript example. Input/output fields are in the types reference.

setRequestBlocking

Declare or clear an agent’s dependency on a reply from one other agent.

setRequestBlocking(id: string, blocking: boolean): Promise<RequestItem>

Parameter	Type and default	Usage
id	string (required)	Existing stable resource ID, returned by the corresponding create/read operation.
blocking	boolean (required)	Explicit requester-declared agent dependency. Ordinary pending questions are not automatically blocking.

Returns: Updated Request with blocking true or false.

Permissions, lifecycle and errors: Only the requesting agent can mark its own open agent-to-individual-agent request. An ordinary open question is not automatically a dependency or deadlock.

Declared return type: Promise<RequestItem>.

Working TypeScript example. Input/output fields are in the types reference.

Example

Run this region after the shared setup. Assertions check the returned data; the full tour is a runnable program.

const request = await builder.ask({ target, body: 'Which region contains order 241?', choices: ['EU', 'US'] }, runId + '/ask');
const current = await billing.getRequest(request.id);
await billing.respond(request.id, { outcome: 'answered', version: current.version, answer: 'EU' });
assert.equal((await builder.wait(request.id, AbortSignal.timeout(5000))).response?.answer, 'EU');
const pending = await builder.ask({ target, body: 'Check order 243 as well.' });
const { replacement: revised } = await builder.replaceRequest(pending.id, { version: pending.version, body: 'Check orders 243 and 244.' }, runId + '/replace');
assert.equal((await builder.cancel(revised.id, revised.version)).state, 'cancelled');
assert.equal((await owner.askBatch({ targets, request: { body: 'Is staging available?' } }, runId + '/ask-batch')).length, 2);
const blocking = await builder.ask({ target, body: 'I need the ledger before continuing.' });
assert.equal((await builder.setRequestBlocking(blocking.id, true)).blocking, true);
await builder.setRequestBlocking(blocking.id, false);
