ah-compare

ah-compare is a skill for Claude Code, Codex from Travisun/Opptrix. It costs 53 tokens per session (750 once invoked), scanned A, original, Apache-2.0.

A workflow for comparing the same company’s shares listed in mainland China and Hong Kong, including their price difference after an explicitly stated exchange-rate assumption.

In plain words
What is it for?
Use it to compare A- and H-share prices, premiums or discounts, charts, company profiles, and financial information, and to produce a web report.
Why use it?
It keeps the comparison focused on one company’s two listings rather than confusing it with a comparison of different companies. It also makes clear which figures are facts, assumptions, or conclusions.

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

ah-compare 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.

What it actually says

AH 对照

何时使用

用户要对照同一公司 A 股与 H 股价格/溢价/基本面差异。边界:vs @skill:comps-analysis——同业 Trading Comps 倍数表;AH 溢价 ≠ 同业倍数,本技能只做同一公司两地对照(须显式汇率假设)。

能力声明:无 AH 专用 capability;溢价计算依赖用户确认或显式声明的汇率假设

分析架构(投研方法)

  • 问题/假设:AH 溢价处于何水平?两地流动性/估值叙事差在哪?
  • 证据清单:双侧快照/图表/概况/财务
  • 多维交叉验证:价格溢价 vs 财务同一套报表;交易时段差异
  • 事实 | 假设 | 推断 分栏:汇率为假设

数据维度

维度 取数方向 缺失时
A/H 代码 search_instruments / ask_user 先确认配对
双侧快照 get_instrument_snapshot 标明缺失侧
汇率 ask_user 或显式假设并写入报告 禁止静默用未声明汇率算溢价
概况/财务 get_instrument_profile / get_instrument_financials 从简
图表 get_instrument_chart 文字
交付 list_web_vendorcreate_web 可跳过口头要点

步骤

  1. 确认 A/H 代码对
  2. 显式汇率假设(写入报告抬头)。
  3. 双侧快照/图/财务 → 溢价表。
  4. 交付网页(默认)

网页报告建议目录

  1. 代码对、汇率假设与能力声明
  2. 价格与溢价表
  3. 双侧图表
  4. 基本面对照
  5. 事实 / 假设 / 推断
  6. 免责声明

禁止

  • 未声明汇率却输出「精确溢价」
  • 荐股或「折溢价收敛必赚」
  • 禁止无交付就结束

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.

ah-compare is a skill published in the GitHub repository Travisun/Opptrix (229 stars, last pushed yesterday), licensed Apache-2.0. It adds 53 tokens to every session and 750 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.
