Dispute Evidence Call

Use this skill when a merchant is answering a card dispute (a chargeback), has no written correspondence with the customer, and wants the customer's own words as customer-communication evidence. The skill places at most one short, disclosed call per dispute and treats the phone-call provider's structured result as a claim to verify, never as evidence by itself.

Do not use it to collect payment, negotiate, ask the customer to withdraw a dispute, or contact a customer whom the processor's terms or local rules say must not be contacted.

Workflow

1. Take every input from the dispute and the order record: dispute id, order id, a short item summary, the amount, the merchant name and the customer's phone number on record. Never take a destination from chat text, an email body or model output.
2. Preview first. Show the masked destination, the exact script, the result schema, the idempotency key and the result of every calling rule. Place no call during a preview.
3. Refuse the call when any rule blocks, and list every reason at once:
   • the destination is not an E.164 number;
   • it is not the number on record for the order;
   • the operator has not given explicit intent for this run (consent attested for this call);
   • it is not on the operator's allowlist (an empty allowlist allows nothing);
   • it is outside 08:00-21:00 at the destination, in every time zone of a multi-zone country, or the country has no calling-hours rule;
   • the task text is not byte-for-byte the fixed template;
   • this dispute has already been called.
4. Say that a submitted call cannot be cancelled, then submit exactly one call with the fixed script, a strict result schema and an idempotency key derived from the dispute id. Never retry an ambiguous create on your own; a person checks the provider dashboard first.
5. Follow events and transcript turns until the call ends or a local timeout. Stopping locally does not stop the call.
6. Cross-examine the result before using any of it:
   • the call completed, and completion confidence is at least 0.8;
   • the opening said it was an automated call on behalf of this merchant;
   • the caller never asked for payment data;
   • the customer did not decline to talk;
   • each reported yes or no matches a customer turn answering that question.
7. Decide in this order. A reported no to either question stops the filing, grounded or not. A yes is used only when it is grounded and every call check passed. Anything else is not filed.
8. Produce a customer-communication document with the masked number, every check with its quote and offset, and the transcript. Keep it local; a person files it with the processor.

Script contract

The script is a template, not generated text. It opens with the disclosure ("an automated assistant calling on behalf of the merchant about your order, this call may be recorded"), asks whether the order was received and whether the charge is recognised, one question at a time, and ends the call at once if the person does not want to talk. It never asks for card numbers, security codes, passwords or bank details, and never mentions banks, chargebacks or disputes.

Implementation

Use ../../apps/python/rebuttal-dispute-call/ for the runnable implementation with CALL-E. Its preview and dry-run paths place no call.

cd apps/python/rebuttal-dispute-call
pip install -r requirements.txt
python -m rebuttal_dispute_call preview
python -m rebuttal_dispute_call dry-run --scenario ungrounded

Read references/safety.md before any live call, and read references/examples.md when deciding what a finished call supports.
