Route Readiness Call

Use this skill when a delivery rider is already on the route and an upcoming customer's readiness would change the order of the remaining stops. It is the reusable core of the RouteReady app in this repository (apps/typescript/routeready): which stop to call, the call task, the result schema, the evidence gate, and the rules that turn an answer into a routing constraint.

When To Use

• A rider is on a multi-stop delivery or service route and the next stops are 6 to 45 minutes away
• The customer gave this phone number for contact about this delivery, and the operator is authorised to call about the order
• The output should be a verified readiness answer that a route optimiser or a dispatcher can act on

When Not To Use

• Marketing, collections, surveys, or anything other than the delivery the customer is expecting
• Stops the rider will reach in under 6 minutes: a call takes about two minutes and the route cannot adapt in time
• A second call to the same customer on the same day, or a retry after an unclear or ambiguous call
• Emergency, medical, legal or financial conversations
• Destinations CALL-E does not currently accept (see references/safety.md)

Required Inputs

• run_id, stop_id: stable identities; the idempotency key is routeready:{run_id}:{stop_id}
• merchant, order_ref
• phone_e164, region (ISO country code), language
• eta_minutes: minutes until the rider arrives, exactly as the customer will be told
• cod_amount: amount due at the door with its currency, or null when prepaid
• authorization_confirmed: the operator confirms the number was given for delivery contact

Picking The Call

There is one line, so only one call may be in flight. Among stops not called today whose projected arrival is 6 to 45 minutes away, call the soonest. Skip the stop the rider is already driving to.

"Called today" is decided by destination number, not by stop: skip a number already called today, even from another stop, route or restarted day, unless a person explicitly approved a repeat call for a different reason. Record the number when the call is attempted, before the create request, so an ambiguous creation counts as today's call.

Preflight

1. Validate the phone against ^\+[1-9]\d{6,14}$ and reject emergency numbers. Reject a plan in which two stops share a number.
2. Before the first live call of a day, show the operator the masked number, the exact task text and the idempotency key.
3. Persist the idempotency key before calling CALL-E, and the returned call id immediately after.

CALL-E Task Template

You are an AI assistant calling on behalf of {merchant} about a parcel delivery. Say in your first sentence that you are an AI assistant calling about their delivery.
Speak {language}, slowly and clearly.
The rider expects to arrive with order {order_ref} in about {eta_minutes} minutes.
Ask: 1) whether they can receive the parcel when the rider arrives, and if not, how many extra minutes they need or whether later today works;
2) if they will not be there, whether a guard, neighbour or family member can receive it;
3) whether the cash payment of {cod_amount} will be ready;
4) a landmark near their door that helps the rider find it.
Do not ask for card, bank, password or identity details. Do not promise an exact delivery time. If it is a wrong number or voicemail, apologise and end the call.
Keep the call under 90 seconds, thank them, and end the call.

For prepaid orders, replace question 3 with 3) do not discuss payment, this order is prepaid;.

Send references/result-schema.json as recipient_result_schema (recipientResultSchema in the TypeScript SDK).

Evidence Gate

Accept an answer only when every condition holds; otherwise record it as unverified and change nothing:

1. The call status is completed and the recipient's number is the planned number.
2. The recipient result parses against the schema: every enum value allowed, every text field a string.
3. reached_recipient is yes.
4. customer_quote is not empty.
5. readiness is not unknown.
6. completion_confidence.label is medium or high.

Do not treat task_completed as evidence that the customer was reached. In testing, a call answered by an automated receptionist came back with task_completed: true and high confidence, and reached_recipient: "no".

Answer To Route Rules

readiness	Routing constraint
ready_now	earliest delivery is now
within_15_min	earliest delivery is the told arrival plus 15 minutes, or ready_clock_time when given
15_to_45_min	earliest delivery is the told arrival plus 45 minutes, or ready_clock_time when given
later_today	take the stop off this loop; revisit after ready_clock_time when given
not_today	take the stop off today's route; rescheduling needs dispatcher approval
unknown	no change

Then re-plan the remaining stops with these earliest times. The reference app tries every order of up to nine stops and minimises finish time plus twice any lateness against promised windows, with a small penalty per moved stop so the route never flips for a trivial gain.

Cancellation And Idempotency

The CALL-E Calls API has no cancel endpoint: once created, a call rings and finishes. Keep one idempotency key per run and stop and reuse it on any retry of the same request, so a lost response never dials twice. Stopping a day stops new calls only. Nothing recurs; every day is started by an operator.

Stop the queue whenever it is unknown whether a call exists:

• A create request that fails with anything other than a CALL-E 4xx refusal (a network error, a timeout, a 5xx, 408 or 409) may have placed the call. Do not move on to the next stop. Stop starting calls for the rest of the day and ask the operator to check the call in the CALL-E dashboard.
• A call that has not reached completed, failed or canceled after 15 minutes is not over. Keep the line busy, keep reconciling that call id, and start no other call.

Only a definite 4xx refusal, such as 422 call_not_ready, means no call exists and the next stop may be called.

Safety Notes

Read references/safety.md before placing a live call. Worked examples, including how the gate treats no answer and automated receptionists, are in references/examples.md.
