An Excel comparison tool that finds changed cells, added rows, removed rows, and header changes between two versions of a worksheet. It can match rows by position or by a unique key such as an order number.

Use it to compare weekly reports, audit edits, or export a separate spreadsheet containing the differences.

It removes the need to inspect two spreadsheets manually and makes changes traceable when row order has changed.

Token cost

What it costs to keep this loaded

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	$0.00062	$0.00583
Opus 5.5	$0.00025	$0.00233
Sonnet 5.5	$0.00012	$0.00117
Haiku 4.5	$0.00006	$0.00058

Security

Grade A, and why

excel_diff 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 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (__init__.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

What it actually says

excel_diff Skill

比对两份 Excel，输出单元格级差异，可导出差异表

功能描述

把两份 Excel 的同一张工作表做对比，返回每个变化的单元格、新增行、删除行和表头变化。支持两种模式：按行号逐格比对（适合行顺序固定的表），或按主键配对后再比对（适合行顺序会变、但每行有唯一编号的表）。

所属分类

skills/excel/excel_diff/

调用方式

from skills.excel import excel_diff

excel_diff(
    before_path='上周报表.xlsx',
    after_path='本周报表.xlsx',
    key_column='订单号',
)

参数说明

参数	类型	必填	默认值	说明
`before_path`	str	是	-	变更前的 Excel 路径
`after_path`	str	是	-	变更后的 Excel 路径
`sheet_name`	str	否	`None`	工作表名，默认取第一个
`key_column`	str	否	`None`	主键列名；指定后按主键配对行
`ignore_case`	bool	否	`False`	文本比较是否忽略大小写
`output_path`	str	否	`None`	差异表输出路径，指定后写出 .xlsx

返回值

dict，包含 mode、sheet、header、summary、changes、added_rows、 removed_rows、output_path 八个键。summary 中的 identical 表示两份表是否完全一致。

使用示例

from skills.excel import excel_diff

result = excel_diff('v1.xlsx', 'v2.xlsx', key_column='编号', output_path='差异.xlsx')
print(result['summary'])
for item in result['changes']:
    print(item['key'], item['column'], item['before'], '->', item['after'])

What ships with it

Changes

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.
