About This Skill
What it does
This skill identifies and removes duplicate documents within your WeChat folder. It operates by comparing the content of files using MD5 hash, ensuring true duplicates are found even if filenames differ. Duplicate files are safely moved to a quarantine folder instead of being deleted, allowing for review and potential restoration.
When to use it
- You have a large WeChat folder with many PDF or Word documents.
- Files have been forwarded multiple times across different chats, creating duplicates.
- You're experiencing storage space issues due to redundant files in your WeChat directory.
- You want to clean up your WeChat file archive and organize the original versions of documents.
Key capabilities
- Content-based detection: Identifies duplicates based on MD5 hash.
- Safe operation: Moves duplicate files to a quarantine folder.
- Smart retention: Keeps the oldest (original) version of each document.
- Detailed report: Generates a markdown report (
去重报告.md) documenting all actions taken.

Tips & gotchas
- The skill currently auto-detects the WeChat folder on macOS. Ensure your WeChat data is stored in a standard location for proper scanning.
- Files are moved to a quarantine folder (
~/微信重复文件_待删除/) with a 30-day holding period, allowing you to recover them if needed.

TrustedSkills Verification
Unlike other registries that point to live repositories, TrustedSkills pins every skill to a verified commit hash. This protects you from malicious updates — what you install today is exactly what was reviewed and verified.
Installing this skill downloads the exact code at commit 71aed8ba, not the current state of the repository. This prevents supply-chain attacks from unauthorized updates.
