Connect Slack two-way channel to DeepSeek Harness with dsh-slack
dsh-slack is a DeepSeek Harness community plugin maintained by STARDUSTLC666, enabling two-way communication between agents and Slack. It registers four tools: slack_notify for sending Markdown notifications, slack_channels for listing visible channels, slack_inbox for receiving messages via Socket Mode, and slack_reply for replying to messages by thread. Starting from version v0.2, public network callbacks are no longer required; it supports custom slackApiUrl to connect to proxy gateways, and the repository has a built-in mock Slack server for protocol-level acceptance testing. This article verifies the installation, configuration and restrictions based on the directory page and GitHub source code.
