refund-request

refund-request is a skill for Claude Code from theYahia/WWmcp. It costs 21 tokens per session (414 once invoked), scanned A, original, MIT.

A procedure for issuing full or partial refunds for MercadoPago payments. MercadoPago is a payment service, and the procedure checks the payment before making and confirming the refund.

In plain words
What is it for?
Use it to find a payment by ID or order reference, check its status and previous refunds, confirm the amount, submit the refund, and read back the result.
Why use it?
It helps prevent refunds for payments that are not approved and avoids refunding too much when part of a payment was already returned. It also requires confirmation because refunds cannot be undone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

refund-request scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/refund-request — Refund

Algorithm

  1. Locate the payment. If the user gave a payment_id, call get_payment with it. If they gave an order reference, call search_payments with external_reference set to it.
  2. Check the status. Only approved payments can be refunded. If it is pending, rejected or already refunded, stop and report that — do not attempt the refund.
  3. Check what is already refunded on the payment record. A second full refund on a partially refunded payment will fail or over-refund.
  4. Confirm the amount with the user. Omit amount for a full refund; pass a number for a partial one.
  5. Call refund_payment with payment_id and, for a partial, amount.
  6. Call get_payment again to read back the resulting status and refunds list.

Response format

## MercadoPago refund

**Payment**: 1315432109 (ORDER-2026-0142)
**Original**: 17,000 ARS — approved
**Previously refunded**: 0
**This refund**: 8,500 ARS (partial)
**New status**: partially_refunded

Notes

  • Refunds are irreversible. Always confirm the amount with the user before calling.
  • MercadoPago's own fee is generally not returned on a refund — do not tell the user they get the full gross back unless the response says so.
  • A charged_back payment is a dispute, not a refund. Refunding it on top of the chargeback double-pays; check status first.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
