Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00000 | $0.00898 |
| Opus 5 | $0.00000 | $0.00449 |
| Sonnet 5 | $0.00000 | $0.00180 |
| Haiku 4.5 | $0.00000 | $0.00090 |
Grade A, and why
Hong Kong SAR — HK CR Lookup 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 12d 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 — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hong Kong SAR — HK CR Lookup
Live, direct-to-government access to 公司註冊處 / Companies Registry of the Hong Kong Special Administrative Region.
Single-country variant of the cross-border Cross-Border UBO Chain Walker. Use this skill when the user is explicitly focused on Hong Kong SAR.
What you get
- Direct query to HK CR. Every tool call hits 公司註冊處 / Companies Registry of the Hong Kong Special Administrative Region at the moment you ask. No nightly scrape, no aggregator middle layer.
- Unmodified responses. Field names, status codes, and (where available) raw filing bytes are returned exactly as the registry's own system emits them.
- Native ID format support. Hong Kong CR number — 7 digits, sometimes prefixed (e.g.
0066011HSBC Holdings plc HK branch). - Sample entity: HSBC Holdings plc (HK branch).
Available tools (jurisdiction = HK)
search_companies, get_company_profile
For every tool, pass jurisdiction: "HK" (case-insensitive).
Example prompts
Look up HSBC Holdings plc's HK branch
Confirm the legal status of Tencent (HK) Holdings Limited
Find Alibaba Group's Hong Kong incorporated entity
Workflow
Step 1 — Resolve the entity
search_companies({ jurisdiction: "HK", query: "<name or ID>" })
get_company_profile({ jurisdiction: "HK", company_id: "<id>" })
Step 2 — Pull the relevant register slice
Pick from the available tools list above. For UBO walks across borders, return to the Cross-Border UBO Chain Walker.
Quirks specific to Hong Kong SAR
- Hong Kong's open data covers basic company status only; full filings (Annual Return NAR1, officer changes) are paid via CR Cyber Search Centre.
- Hong Kong's Significant Controllers Register (SCR) is not publicly accessible — only viewable on-site by AML-obliged entities.
- Hong Kong is a major holding-company jurisdiction in Asia — note
Hong Kong Ltdvs.Foreign Company(registered under Part 16 of CO). - Two language registries — Chinese (Traditional) and English; both names appear.
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.
