Introduction to the DeepSeek Harness Plugin: dsh-message-push

The DeepSeek Harness (DSH) plugin `dsh-message-push` is designed to address monitoring challenges when multi-turn agent sessions are stopped in the background. As a pure push layer, it supports pushing messages via API to QQ, Telegram, Feishu, or WeChat when a task is completed, fails, is blocked, or requires approval. It includes a built-in deduplication mechanism and is responsible only for sending notifications; it does not participate in approval decisions or inject messages. Installation requires a pnpm environment, and configuration requires binding a target account. Other plugins can reuse its API to send notifications.
