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 | $0.00050 | $0.02849 |
| Opus 5 | $0.00025 | $0.01425 |
| Sonnet 5 | $0.00010 | $0.00570 |
| Haiku 4.5 | $0.00005 | $0.00285 |
Grade A, and why
adr-hshare 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 10d 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.
This is a copy
100% identical to adr-hshare — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

ADR / H-Share / A-Share Cross-Listing Analysis
Overview
Many Chinese companies are listed on multiple exchanges — A-shares in Shanghai/Shenzhen, H-shares in Hong Kong, and ADRs in the US. Pricing gaps between these listings create arbitrage opportunities and reveal market-specific sentiment differences. This skill provides frameworks for analyzing cross-listing premiums, identifying arbitrage signals, and assessing delisting risk for US-listed Chinese ADRs.
Core Concepts
1. Cross-Listing Structures
| Structure | Description | Examples |
|---|---|---|
| A + H dual-listed | Same company listed on both A-share and HK exchange | PetroChina (601857.SH / 0857.HK), ICBC (601398.SH / 1398.HK) |
| H + ADR dual-listed | HK-listed with US ADR | Alibaba (9988.HK / BABA), JD.com (9618.HK / JD) |
| A + H + ADR triple-listed | All three markets | China Life (601628.SH / 2628.HK / LFC) |
| HK primary + US secondary | Primary listing in HK, secondary ADR | Tencent (0700.HK / TCEHY OTC) |
| US primary → HK secondary | Originally US, added HK listing | Alibaba (BABA → 9988.HK), Baidu (BIDU → 9888.HK) |
2. AH Premium Analysis
AH Premium = (A-share price / H-share price in CNY terms - 1) × 100%
def calculate_ah_premium(a_price_cny, h_price_hkd, usdcny, usdhkd):
"""Calculate AH premium for a dual-listed stock."""
h_price_cny = h_price_hkd * (usdcny / usdhkd) # Convert HKD to CNY
ah_premium = (a_price_cny / h_price_cny - 1) * 100
return ah_premium
# Example: PetroChina
# A-share: 8.50 CNY, H-share: 6.20 HKD
# USDCNY: 7.25, USDHKD: 7.82
# H in CNY: 6.20 * (7.25/7.82) = 5.75 CNY
# AH Premium: (8.50/5.75 - 1) * 100 = 47.8%
AH Premium signal interpretation:
| Premium Level | Interpretation | Action |
|---|---|---|
| >50% | Extreme A-share premium; A-share speculative bubble or H-share extreme undervaluation | Strong: buy H, sell/avoid A |
| 30-50% | Elevated premium; normal for high-retail-participation names | Moderate: favor H if fundamentals same |
| 10-30% | Normal range for most AH pairs | Neutral; no strong arbitrage signal |
| 0-10% | Compressed premium; A-shares relatively cheap | Unusual; investigate catalyst |
| <0% | H-share premium over A-share | Very rare; usually near-term event-driven |
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.

adr-hshare is a skill published in the GitHub repository skloxo/TideTrading (10 stars, last pushed 3d ago), licensed MIT. It adds 50 tokens to every session and 2,849 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to adr-hshare, differing in 0 lines, and is treated as a copy.
