Missing User Warnings

Medium
Confidence
86% confidence
Finding
The skill recommends uploading screenshots,成果展示,资质证明, and preserving chat records, but it never warns users to redact personal or sensitive information before sharing. In this marketplace context, that omission can lead to accidental exposure of phone numbers, IDs, account details, client data, or private conversations in public listings or dispute evidence.
