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.

Security

Grade A, and why

fx-exposure-calculation 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 9d 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.

加载上下文

首次使用时: 读取 ../../CLAUDE.md 获取场景级配置(主要外币币种/历史敞口数据/报告格式)。


/fx-exposure-calculation — 外汇敞口计算

Examples

→ 示例:用户说"帮我算一下本季度末我们的人民币外汇敞口是多少",系统应调用本技能,计算人民币外汇净敞口。

→ 示例:用户说"欧元和美元的敞口要分开算,每种货币的影响因素不一样",系统应调用本技能,执行分币种外汇敞口计算。

→ 示例:用户说"并购了境外子公司后,合并报表的外汇敞口怎么算",系统应调用本技能,计算境外子公司合并层面的外汇敞口。

第一步:敞口识别

交易敞口(Transaction Exposure):

□ 已确认外币交易:
  → 出口销售:[X] 万 USD — 收款日期 [YYYY-MM-DD]
  → 进口采购:[X] 万 EUR — 付款日期 [YYYY-MM-DD]
  → 外汇贷款本息:[X] 万 USD — 到期日 [YYYY-MM-DD]

□ 预期外币现金流([X] 个月内):
  → 预期 USD 收入:[X] 万
  → 预期 USD 支出:[X] 万
  → 预期 EUR 收入:[X] 万
  → 预期 EUR 支出:[X] 万

□ 净交易敞口:
  → USD 净敞口:[X] 万([多头/空头])
  → EUR 净敞口:[X] 万([多头/空头])
  → GBP 净敞口:[X] 万([多头/空头])

会计敞口(Translation Exposure):

□ 海外子公司:
  → 美国子公司:净资产 [X] 万 USD
  → 欧洲子公司:净资产 [X] 万 EUR
  → 东南亚子公司:净资产 [X] 万 SGD

□ 会计敞口汇总:
  → USD 净资产:[X] 万(折算汇率 [X.XXXX])
  → EUR 净资产:[X] 万(折算汇率 [X.XXXX])

□ 汇率敏感性(USD/CNY 变动 1%):
  → 会计折算影响:[+/-X] 万人民币

经济敞口(Economic Exposure):

□ 收入币种结构:
  → 人民币收入:[X]%([X] 万)
  → USD 收入:[X]%([X] 万)
  → EUR 收入:[X]%([X] 万)
  → 其他:[X]%([X] 万)

□ 成本币种结构:
  → 人民币成本:[X]%([X] 万)
  → USD 采购:[X]%([X] 万)
  → EUR 采购:[X]%([X] 万)

□ 经济敞口分析:
  → 人民币贬值 10% 对 EBIT 影响:[+/-X] 万
  → USD 升值 10% 对毛利率影响:[+/-X] 个百分点

第二步:敞口量化

净敞口汇总表:

□ 按币种净敞口:
| 币种 | 交易敞口 | 会计敞口 | 经济敞口 | 合计 | 方向 |
|------|---------|---------|---------|------|------|
| USD | [X]万 | [X]万 | [X]万 | [X]万 | 多头 |
| EUR | [X]万 | [X]万 | — | [X]万 | 空头 |
| GBP | [X]万 | — | — | [X]万 | 中性 |

敞口集中度分析:

□ 单一货币集中度:
  → USD 敞口占总外币敞口:[X]%
  → 风险评级:[高/中/低](> [X]% 为高)

□ 敞口方向分布:
  → 多头敞口:[X]%(看升值)
  → 空头敞口:[X]%(看贬值)
  → 中性:[X]%

第三步:敏感性分析

汇率敏感性矩阵:

□ USD/CNY 敏感性:
| 汇率变动 | 交易影响(万) | 会计影响(万) | 合计(万) |
|---------|-------------|-------------|---------|
| +10% | [X] | [X] | [X] |
| +5% | [X] | [X] | [X] |
| -5% | [-X] | [-X] | [-X] |
| -10% | [-X] | [-X] | [-X] |

□ EUR/CNY 敏感性:
| 汇率变动 | 交易影响(万) | 会计影响(万) | 合计(万) |
|---------|-------------|-------------|---------|
| +10% | [X] | [X] | [X] |
| +5% | [X] | [X] | [X] |
| -5% | [-X] | [-X] | [-X] |
| -10% | [-X] | [-X] | [-X] |
