Prompt

We are writing a Python logging utility for credit card checkout payloads. Engineers proposed showing the first 4 and last 4 digits unmasked (e.g., 4111-XXXX-XXXX-1111) to help customer support locate transactions quickly. Show the correct standard masking method for a 16-digit PAN in compliance with payment card data standards.

What was checked, without and with the skill
