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 | $0.00059 | $0.00439 |
| Opus 5 | $0.00030 | $0.00219 |
| Sonnet 5 | $0.00012 | $0.00088 |
| Haiku 4.5 | $0.00006 | $0.00044 |
Grade A, and why
xlsx-author 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 11d 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.
What it actually says
无头Excel工作簿生成
使用场景
当CI、Codex、Claude Code或其他命令行环境没有实时Office工具,而下游Skill明确需要.xlsx文件时使用。默认通过Python openpyxl写入./out/<name>.xlsx;先创建./out/,最终返回相对路径供调用方收集。
工作簿约定
- 输入、公式与跨表链接分别使用蓝、黑、绿字体;所有硬编码输入必须集中在Inputs或Sources并带来源/
[ASSUMPTION]。 - 计算单元格使用公式,不直接粘贴最终结果;需被报告引用的关键值建立命名范围。
- Checks页至少覆盖模型特有的勾稽、错误值、终值/价值桥或敏感性中心格。
- 默认每次创建新文件;除非用户明确要求,不覆盖现有工作簿。
openpyxl写入公式不等于公式已由Excel/LibreOffice重算。未调用真实重算引擎时必须写formula_recalculation_unverified。
最小实现
用短Python脚本创建工作簿、样式、公式、命名范围和Checks页,保存到./out/。随后调用audit-xls检查结构、公式和错误值;只有实际执行过重算引擎,才可把公式状态从implemented提升为formula_recalculated。
不使用场景
若宿主提供并已连接实时Excel控制工具,使用实时工具并保留用户审阅检查点。本Skill只负责文件型回退,不驱动交易或账户系统。
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.

xlsx-author is a skill published in the GitHub repository cyijun/china-financial-services (19 stars, last pushed 17d ago), licensed Apache-2.0. It adds 59 tokens to every session and 439 once invoked, about $0.0003 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 2026-08-30.
