WeChat 文档去重 Skill

What problem does it solve?

WeChat often creates multiple copies of the same document when files are forwarded, saved from different chats, or synced across devices, which wastes storage and makes document management tedious.

Core Features & Use Cases

• Content-based detection: Groups files by size and verifies identical content with MD5 hashing so duplicates are found regardless of filename.
• Safe quarantine workflow: Keeps the earliest-created file and moves duplicates to a quarantine folder instead of deleting them, allowing recovery.
• Preview and reporting: Presents a preview for confirmation and generates a detailed markdown report of all actions and space saved.
• Use Case: Recover gigabytes of storage by scanning WeChat PDF and Word documents, quarantining forwarded or re-saved duplicates while preserving originals.

Quick Start

Say 微信去重 or wechat dedup to scan your WeChat folders, preview detected duplicates, and move confirmed duplicates to the quarantine folder.
