WechatSync

Multi-platform article publisher and content distribution tool. Sync and cross-post Markdown/HTML articles to 27+ platforms including Zhihu (知乎), Juejin (掘金)...

Publish and sync Markdown/HTML articles to 27+ content platforms via CLI.

Prerequisites

This skill requires external tools that the user must install themselves:

1. CLI tool (@wechatsync/cli): Open-source npm package (source code). Install with npm install -g @wechatsync/cli
2. Chrome extension: Open-source browser extension (source code). Install from Chrome Web Store or download ZIP
3. Token: User-generated token set in extension settings. The token is created locally by the user and used only for localhost communication between CLI and extension. Set via export WECHATSYNC_TOKEN="your-token"
4. Platform logins: Log in to target platforms in browser (extension uses existing browser cookies, no credentials are stored or transmitted)

Security model: All data stays local. The CLI communicates with the Chrome extension over localhost. The extension calls platform APIs directly from the browser using existing login sessions. No third-party server involved. Full source code is open and auditable.

Before running any command, confirm the user has completed the prerequisites. Do not install packages on the user's behalf without explicit consent.
