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 | $0.00085 | $0.01785 |
| Opus 5 | $0.00043 | $0.00892 |
| Sonnet 5 | $0.00017 | $0.00357 |
| Haiku 4.5 | $0.00009 | $0.00178 |
Grade A, and why
invoice-verification 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.
How it starts
The opening of the file, as written. The whole thing — 194 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/invoice-verification — 发票验真
Examples
→ 示例：用户说"收到供应商发票，帮我核对一下和合同条款是否一致"，系统应调用本技能，执行发票条款核对。
→ 示例：用户说"发票上的银行账号和合同里不一样，能不能付"，系统应调用本技能，核查发票付款信息变更。
→ 示例：用户说"帮我们审一下这张大额发票，确保没问题再走付款流程"，系统应调用本技能，执行大额发票专项审核。
支持的发票类型
| 发票类型 | 查验平台 | 注意事项 |
|---|---|---|
| 增值税专用发票 | 必查验，全国互通 | 最核心，涉税最大 |
| 增值税普通发票（卷式/电子） | 查验 | 部分平台支持 |
| 机动车销售统一发票 | 查验 | 与车辆购置税联动 |
| 通行费发票（收费公路） | 有限查验 | 仅部分省市支持 |
| 定额发票（餐饮/停车） | 抽查 | 无法在线查验，须人工核对 |
查验步骤
第一步：获取查验参数
必须参数（4项）：
发票代码：发票左上角 10 位或 12 位代码
发票号码：发票右上角 8 位号码
开票日期：YYYY-MM-DD 格式
校验码：增值税专用发票的 20 位校验码（普票的 6 位）
（备注：如校验码不完整，用前 6 位 + 后 4 位替代）
金额参数（二选一）：
不含税金额（开具金额）
价税合计金额（含税金额）
平台会取其中一种进行核对
第二步：执行查验
查验入口：
官网：https://inv-veri.chinatax.gov.cn
API（已配置 MCP）：
→ 自动传入参数，返回结构化结果
手动（无 MCP 时）：
→ 打开查验平台网页
→ 依次输入上述 4 项参数
→ 获取查验结果
第三步：解析查验结果
| 查验结果 | 含义 | 操作 |
|---|---|---|
| 一致 | 票面所有信息与系统记录完全匹配 | ✅ 查验通过 |
| 不一致 | 金额/税号/品名与系统记录不符 | ❌ 疑似问题发票，驳回 |
| 查无此票 | 发票代码+号码在系统中不存在 | ❌ 假票，直接驳回 |
| 作废 | 发票已被开票方作废 | ❌ 不可使用，驳回 |
| 红冲 | 发票已被开票方冲销 | ❌ 不可使用，驳回 |
| 失控 | 专票已被异地认证，税局标记失控 | ❌ 不可使用，驳回 + 升级 |
| 平台不可用 | 查验网站无法访问 | ⚠️ 引导用户截图备用，要求人工查验 |
特殊场景处理
场景一：发票延迟同步
问题： 发票刚开具，税局系统约需 1 天同步，暂时"查无此票"
处理：
判断：开票日期距今 ≤ 5 个工作日
→ "一致"的概率高，标注"暂无法验真（发票数据同步延迟），建议 XX 日后再验"
→ 如员工急用，要求提供开票方的作废盘证明（证明未作废）
判断：开票日期距今 > 5 个工作日
→ 仍查不到 → 视为可疑，按"查无此票"处理
场景二：金额轻微差异
问题： 验真平台返回"不一致"，但差异金额 ≤ 1 元
处理：
差异 ≤ 1 元 → 视为平台数据同步误差
→ ⚠️ 标注"金额轻微差异（±1 元内），建议核对后通过"
→ 要求员工提供开票方盖章的"价税合计说明"
差异 > 1 元
→ 按不一致处理，要求核实后重新提供发票
场景三：失控发票
问题： 专票状态显示"已认证（失控）"
处理：
失控发票不得作为进项抵扣凭证
→ ❌ 驳回报销申请
→ 🔴 升级至财务经理 + 税务专员
→ 记录供应商异常台账
→ 触发供应商重新资质审查

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.

invoice-verification is a skill published in the GitHub repository vivy-yi/finance-skills (28 stars, last pushed 2mo ago), licensed MIT. It adds 85 tokens to every session and 1,785 once invoked, about $0.0004 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.
