DeepSeek Harness can keep the Office file beside the conversation

For anyone extending DeepSeek Harness beyond coding, dsh-univer-office adds a fairly concrete workflow: open an Office file, let the agent edit it, and inspect the actual result inside the same conversation. The plugin's documented inputs include XLSX, CSV, TSV, DOCX and PPTX. While it works, a floating viewer shows the file. A review card stays in the conversation for that file, with options to continue editing, merge the draft, or discard it. The spreadsheet example makes the point better than a feature list: a sales report with revenue, growth and margin figures appears inside the conversation, with the file marked "Merged" and the sheet still marked "Editable". You can inspect the cells and keep editing the report instead of working only from the agent's description of it. The presentation examples also retain editable slide objects. This is an Office plugin for DSH with its own viewer and tools. Installing the separate Univer CLI isn't a prerequisite. The documented web-profile installation is: dsh plugin --profile web add dsh-univer-office Then restart dsh web and refresh the browser page. The current compatibility notes list DSH 0.1.1-rc.2 / 0.1.2-rc.1 and Node 22.19 or newer. A useful first task would be an existing workbook with one chart to change. That gives you something specific to inspect and revise before expanding to a whole report.
