dsh-plugin-wechat-bridge: Put DeepSeek Harness Agent into WeChat Private Chats

What Does It Do?

It is a WeChat bridge plugin for DeepSeek Harness (DSH) that connects WeChat private messages to DSH agent sessions, letting you chat with the agent directly from WeChat. It solves the problem of using DSH on mobile, streaming replies as plain text, and supports media sending/receiving, whitelist control, and session notifications.

Core Features

• WeChat private messages drive agent sessions: polls the WeChat ilink bot API per configured account, triggers agent responses, and sends replies in chunks (4096 chars × up to 5 segments).
• Runtime hot-swap: enable/disable in real time via Settings UI tab, /wechat slash command, or settings.yaml, without restarting the process.
• One session per peer per day: rotates daily based on local timezone, lazily creates a session on the first inbound message, and no file is created if no conversation occurs.
• Crash-safe design: cross-process polling lock, per-chat serialization, inbound deduplication, and corrupted log isolation with self-healing.
• One-way session notifications: sends a fixed-template brief to whitelisted WeChat contacts when any top-level session turn ends, with per-workspace mute support.
• Inbound whitelist (fail-closed): empty allowedPeers rejects everyone; matches robot internal contact IDs.
• Outbound media: agent calls the wechat_send_file tool to upload images/videos/files to the current peer.
• Inbound media: automatically downloads and decrypts images/files/videos/voice from WeChat, storing them in a designated directory.

How to Use This Plugin?

After enabling it in DSH, first scan a QR code to bind a WeChat account with ilink bot permission (bot_type=3), then send a private message to the bot. Replies will be streamed back as plain text, just like in the GUI. You can manage accounts, whitelist, notifications, and other settings via the Settings tab or /wechat command.
