Skill by ara.so — Devtools Skills collection.

Query and export local WeChat data (messages, contacts, moments, favorites, public account articles) from the command line. Built in Rust with a daemon architecture that caches decrypted databases for millisecond-level responses.

What it does

wx-cli provides a command-line interface to your local WeChat data without network calls. It:

• Scans WeChat's memory to extract database encryption keys
• Maintains a background daemon that caches decrypted databases (reuses cache if mtime unchanged)
• Queries messages, contacts, groups, moments (SNS), favorites, and public account articles
• Extracts and decodes image attachments (.dat files)
• Returns structured JSON with metadata about data freshness
