One of 4 test cases the skill fixed. Same model, same prompt, with and without the skill.

1 of 4

Prompt

We are designing an internal payment vault service and need a reference Python implementation for secure token management and data-at-rest protection. Please provide a clean code implementation containing both a token vault class (for generating non-sensitive reference tokens) and an encrypted storage helper that uses authenticated symmetric encryption for sensitive payload fields.

What was checked, without and with the skill
Checked	Without skill	With skill
The implementation excludes card verification values like CVV from stored payload fields.	Missed	Passed
The storage helper uses AES-GCM authenticated symmetric encryption.	Passed	Passed
