Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00079 | $0.01038 |
| Opus 5.5 | $0.00032 | $0.00415 |
| Sonnet 5.5 | $0.00016 | $0.00208 |
| Haiku 4.5 | $0.00008 | $0.00104 |
Grade A, and why
excel-workbook scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 23d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Excel 工作簿基础操作
当用户要求创建、检查、编辑或验证 .xlsx 文件时使用本 Skill。
支持范围
支持以下基础操作:
- 检查工作簿、工作表、行列范围、公式、日期和合并单元格;
- 创建包含表头、数据和简单公式的新工作簿;
- 编辑单元格、追加行和基础数字格式;
- 保留已有工作表、公式、日期、数据类型和未修改区域的基础样式;
- 重新打开输出文件,验证关键内容;
- 设置 Excel/WPS 打开文件时自动重算的标记。
当前版本只支持 .xlsx。不处理 .xlsm 宏、VBA、图表、数据透视表、
Power Query、外部工作簿引用或复杂财务模型。
工作原则
- 先检查,再修改。
- 默认不覆盖原文件;编辑时输入文件和输出文件必须是不同路径。
- 修改现有模板时,只改用户指定的单元格或区域,不重建整个工作簿。
- 日期、数字和公式要保持正确的数据类型。公式字符串被写入不等于公式已经计算。
- 修改后必须重新打开输出文件并验证。
- 没有 Excel、WPS 或 LibreOffice 重算结果时,不要声称公式结果已经验证。
工具脚本
脚本位于当前 Skill 的 scripts/workbook_tool.py:
python scripts/workbook_tool.py inspect input.xlsx
python scripts/workbook_tool.py create output.xlsx --spec spec.json
python scripts/workbook_tool.py edit input.xlsx output.xlsx --operations operations.json
python scripts/workbook_tool.py validate output.xlsx --expect expectations.json
python scripts/workbook_tool.py recalc output.xlsx
所有命令默认输出 JSON,便于继续检查和记录。
创建数据格式
create 的 spec 使用以下结构:
{
"sheet": "销售数据",
"headers": ["日期", "商品", "金额", "含税金额"],
"rows": [
[
{"date": "2026-09-16"},
"A",
100,
{"formula": "=C2*1.1"}
]
],
"column_widths": {"A": 14, "C": 12, "D": 14}
}
日期使用 {"date": "YYYY-MM-DD"},公式使用 {"formula": "=..."}。
编辑数据格式
edit 的 operations 使用以下结构:
{
"set_cells": [
{"sheet": "销售数据", "cell": "C2", "value": 120},
{"sheet": "销售数据", "cell": "D2", "formula": "=C2*1.1"},
{"sheet": "销售数据", "cell": "A2", "date": "2026-09-17"}
],
"append_rows": [
{
"sheet": "销售数据",
"values": [{"date": "2026-09-18"}, "B", 80, {"formula": "=C3*1.1"}]
}
],
"number_formats": [
{"sheet": "销售数据", "cell": "C2", "format": "#,##0.00"}
]
}
验证数据格式
validate 的 expectations 使用以下结构:
{
"sheets": ["销售数据"],
"cells": {
"销售数据!C2": 120,
"销售数据!D2": "=C2*1.1",
"销售数据!A2": {"date": "2026-09-17"}
},
"required_formulas": ["销售数据!D2"]
}
重算边界
recalc 会先设置:
calcMode=auto
fullCalcOnLoad=true
forceFullCalc=true
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

excel-workbook is a skill published in the GitHub repository adongwanai/learn-workbuddy (437 stars, last pushed today), licensed MIT. It adds 79 tokens to every session and 1,038 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-24.
