dsh-officeDeepSeek Harness plugin

@huiliyi37/dsh-office

English | 中文

Office document tools for DeepSeek Harness (dsh): generate, read, and edit spreadsheets (.xlsx), PDFs, presentations (.pptx), and Word documents (.docx).

Ported from the office plugins of the Tianshu terminal coding agent (Apache-2.0 licensed upstream), adapted to the dsh cordis tool model.

Tools

Tool	What it does
xlsx_read	List sheets of a .xlsx, or read one sheet as a markdown table (range-limited for large files; formula text preserved)
xlsx_write	Write a 2D array to a new .xlsx (formula cells, header bold, column widths, number formats)
xlsx_edit	Edit an existing .xlsx: add sheets, update cells (value or formula), append rows
xlsx_recalc	Recalculate every formula with a lightweight pure-TS engine and report error values (#REF!, #DIV/0!, #VALUE!, #N/A, #NAME?, #NUM!) with locations
xlsx_audit	Statically audit formula structure: array-formula traps, aggregation ranges missing rows, formulas overwritten by hardcoded values, inconsistent formulas in a column, self-references, division by zero
pdf_create	Generate a real PDF with headings, paragraphs, tables, lists, code blocks and footer page numbers; CJK text renders via an auto-detected system font
pdf_read	Extract text from a PDF for reading into context
pdf_merge	Merge multiple PDFs into one, in order
pdf_split	Split a PDF into single-page files, or extract pages by spec ("1,3,5-7")
pptx_create	Generate a .pptx deck from slide definitions (title / section / content / two-column / image / table / chart), with optional theme and speaker notes
pptx_read	Extract slide text as markdown, optionally including speaker notes; include adds structure (summary/layouts/images/tables: shape names & cm positions, image targets, table dims)
pptx_edit	Find/replace text inside an existing .pptx (<a:t> surgery), preserving all layout and styling
docx_create	Generate a real .docx Word document from content blocks (heading / paragraph / table / code / list), with optional striped tables, page background color, and diagonal text watermark
docx_read	Extract text from a .docx for reading into context

Install & load

Compatibility: requires dsh ≥ 0.1.0-rc.5 (bundles @deepseek-ai/dsh-tools ≥ 0.1.0-rc.5). Installing on an older core whose dsh-tools is a 0.0.1 release installs a second dsh-tools copy and crashes every tool call with Cannot read properties of undefined (reading 'prepare').

Full load (all 14 tools)

sh
dsh plugin --profile <name> add @huiliyi37/dsh-office
dsh --profile <name>

The first dsh plugin call initializes the profile (@deepseek-ai/dsh-base is its first bundle) and appends this package to the profile's bundles list. Launching the profile then registers all tools automatically.

Load only the families you need

Pass a config row in your profile's cordis.patch.yml to enable/disable per family. Omitted families stay enabled; set a family to false to exclude it (useful to keep the tool surface small):

yaml
# cordis.patch.yml
- insert:
    - id: dsh-office
      name: '@huiliyi37/dsh-office'
      config:
        enable:
          xlsx: false      # skip spreadsheet tools
          pdf: true        # keep PDF tools
          ppt: false       # skip presentations
          docx: true       # keep Word tools

Families: xlsx (read/write/edit/recalc/audit), pdf (create/read/merge/split), ppt (create/read/edit), docx (create/read).

Uninstall

sh
dsh plugin --profile <name> remove @huiliyi37/dsh-office

Manual alternative

Install the package anywhere Node resolution can find it and reference it from your own cordis.patch.yml (same config.enable switches apply):

sh
npm install @huiliyi37/dsh-office

yaml
# cordis.patch.yml
- insert:
    - id: dsh-office
      name: '@huiliyi37/dsh-office'

Skill

The package ships a usage skill (skills/SKILL.md, anthropics-compatible format) that teaches the model large-file pagination and generation discipline. Install it into a skill discovery root:

sh
mkdir -p ~/.dsh/skills && cp -r node_modules/@huiliyi37/dsh-office/skills/dsh-office ~/.dsh/skills/
