DeepSeek Harness QQBot Plugin: Integrating QQ Bot into Persistent Harness Sessions

This article introduces the open-source plugin `sliverp/DeepSeek-harness-qqbot`, designed to address the lack of a ready-to-run QQ plugin for the DeepSeek Harness (DSH) channel. Based on the official QQ Bot Gateway client, this plugin integrates QQ C2C and group chat into a persistent Harness agent. Core features include: support for bidirectional transmission of text, images, and files, with file sending restricted to within the workspace and a maximum size of 100 MiB; session management capabilities, allowing users to switch or reset sessions via commands; a strict approval mechanism that enables the initiating user to approve or reject requests with a single button click, supporting automatic rejection on timeout and fallback channels; and integration with the DSH credential service for secure credential parsing and access policy configuration.
