Calc Spreadsheets

Documents
calc-spreadsheets

Calc Spreadsheets is an Agent Skill for documents published in the agent0ai/agent-zero repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.

Use when creating, opening, or editing LibreOffice Calc ODS spreadsheets, or XLSX workbooks only when Excel compatibility is explicitly required.

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

  1. Open your project in Codex.
  2. Copy and paste the prompt below.
  3. Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/agent0ai/agent-zero/blob/HEAD/plugins/_office/skills/calc-spreadsheets/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/calc-spreadsheets, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

Calc Spreadsheets

Use ODS when the user asks for a spreadsheet, workbook, editable table, budget, formulas, or Calc file. Use XLSX only when the user asks for Excel/XLSX compatibility, provides an existing .xlsx, or needs embedded spreadsheet charts supported by the tool.

The document UI and Desktop are user-owned. Creating or editing an ODS or XLSX must save the workbook, but must not open a document modal or Desktop surface automatically. Use Desktop/Calc only for explicit GUI requests, visual chart/layout polish, or final visual confirmation. Do not write faux UI action labels such as "Open document" or "Download file", and do not add a note saying the canvas was not opened automatically unless the user explicitly asks about UI behavior.

Workflow

Create a workbook:

{
  "tool_name": "office_artifact",
  "tool_args": {
    "action": "create",
    "kind": "spreadsheet",
    "title": "Budget",
    "format": "ods",
    "content": "Item,Amount\nPlatform,1000"
  }
}

For a blank workbook request, create a simple workbook with the requested title and format: "ods"; do not call status first unless the user asked for availability.

Edit cells:

{
  "tool_name": "office_artifact",
  "tool_args": {
    "action": "edit",
    "file_id": "abc123",
    "operation": "set_cells",
    "cells": {
      "Sheet1!A1": "Item",
      "Sheet1!B1": "Amount"
    }
  }
}

Practical rules:

  • content may be CSV, TSV, or a Markdown table; the tool writes real spreadsheet cells.
  • Use rows for whole-table replacement, append_rows for adding records, and set_cells for precise edits.
  • Use create_chart with a chart object for embedded charts when working in XLSX compatibility format; otherwise use Calc/Desktop or code execution for chart workflows that ODS direct editing does not yet cover.
  • Do not open Calc/Desktop automatically. The user can choose Open in Desktop when they want the visible spreadsheet.
