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 | $0.00160 | $0.03684 |
| Opus 5 | $0.00080 | $0.01842 |
| Sonnet 5 | $0.00032 | $0.00737 |
| Haiku 4.5 | $0.00016 | $0.00368 |
Grade A, and why
excel-replace 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 5d 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 — 337 lines — stays where its author put it; the contents beside it link to each section on GitHub.
This skill follows [[excel-safe-workflow]] four-step method. Must complete Requirement Parsing→Scout→Plan before execution, and Verify after. Must confirm before overwriting. 本技能遵循 [[excel-safe-workflow]] 四步法。执行前必须完成 需求解析→勘察→规划,执行后必须验证。替换覆盖前必须确认。
Excel Safe Replace (Column/Row/Cell) / Excel 安全替换(列/行/单元格)
第零步:需求解析
自动识别替换范围 / Auto-detect Replace Scope
| 用户说 | 判定 |
|---|---|
| "这列全改成""E列替换为""整列" | → 整列模式 |
| "这行全改成""第5行替换为""整行" | → 整行模式 |
| "把所有空值改成""xxxx的替换为""条件替换" | → 条件单元格模式 |
| "B5改成""这个单元格" | → 单单元格模式 |
解析要素
| 要素 | 说明 | 默认值 |
|---|---|---|
| 范围 | 整列/整行/条件/单格 | 从用户话中判定 |
| 目标 | 列号/列名/行号/单元格坐标 | 必须明确 |
| 新内容 | 固定值 / =开头的公式 / 自定义转换 |
必须明确 |
| 条件 | (仅条件模式)"等于xx的""包含xx的""为空的" | 必须明确 |
解析示例
| 用户说 | 提取 |
|---|---|
| "把E列全部替换成'已确认'" | 整列, E, 值='已确认' |
| "第3行整行清空" | 整行, 3, 值=None |
| "状态列里所有'待审'改成'已审'" | 条件, 状态列, 匹配='待审'→'已审' |
| "把空单元格全填上0" | 条件(全局), 匹配=None→0 |
| "B5改成'总计'" | 单格, B5, 值='总计' |
| "金额列换成公式 =C2*D2" | 整列, 金额列, 公式='=C2*D2' |
第一步:勘察
import os, sys
sys.stdout.reconfigure(encoding='utf-8')
from openpyxl import load_workbook
from datetime import datetime
FILE = '目标文件.xlsx'
size_mb = os.path.getsize(FILE) / 1024 / 1024
print(f'文件大小: {size_mb:.1f} MB')
wb = load_workbook(FILE)
ws = wb.active
print(f'工作表: {ws.title}, 行: {ws.max_row}, 列: {ws.max_column}')
# 定位目标
target_col = None # 整列模式
target_row = None # 整行模式
target_cell = None # 单格模式
# 整列模式:定位列号
if SCOPE == 'column':
if isinstance(target_spec, str):
for col_idx in range(1, ws.max_column + 1):
if ws.cell(row=1, column=col_idx).value == target_spec:
target_col = col_idx
break
else:
target_col = int(target_spec)
print(f'\n目标列: 列{target_col} "{ws.cell(row=1, column=target_col).value}"')
# 抽样展示
for row in range(2, min(10, ws.max_row + 1)):
v = ws.cell(row=row, column=target_col).value
print(f' 行{row}: {repr(v)[:50]}')
# 条件模式:统计匹配数
if SCOPE == 'condition':
match_count = 0
for row in range(2, ws.max_row + 1):
for col in range(1, ws.max_column + 1):
v = ws.cell(row=row, column=col).value
if CONDITION(v): # 用户定义的条件
match_count += 1
print(f'\n条件匹配: {match_count} 个单元格(共 {ws.max_row * ws.max_column} 个)')
# 双重扫描
print('\n=== 双重扫描 ===')
wb2 = load_workbook(FILE, data_only=True)
ws2 = wb2.active
# ... 对比 target 区域
wb2.close()
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.
- 5d ago First seen · 337 lines · 160 tokens per session scan A b814f3c20929
excel-replace is a skill published in the GitHub repository YuYY2004/excel-skills (2 stars, last pushed 1mo ago), licensed MIT. It adds 160 tokens to every session and 3,684 once invoked, about $0.0008 per session on Opus 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 2026-08-31.
