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 | $0.00957 |
| Opus 5 | $0.00000 | $0.00478 |
| Sonnet 5 | $0.00000 | $0.00191 |
| Haiku 4.5 | $0.00000 | $0.00096 |
Grade A, and why
Germany — Handelsregister 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.
Germany — Handelsregister Lookup
Live, direct-to-government access to Gemeinsames Registerportal der Länder — Handelsregister (Amtsgericht Registergerichte der 16 Länder).
Single-country variant of the cross-border Cross-Border UBO Chain Walker. Use this skill when the user is explicitly focused on Germany.
What you get
- Direct query to Handelsregister. Every tool call hits Gemeinsames Registerportal der Länder — Handelsregister (Amtsgericht Registergerichte der 16 Länder) 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. Court-prefixed Handelsregister number (e.g.
HRB 123456 BBerlin,HRB 12345 München). - Sample entity: Deutsche Bank AG.
Available tools (jurisdiction = DE)
search_companies, get_company_profile, list_filings, get_officers, get_shareholders, get_document_metadata, fetch_document
For every tool, pass jurisdiction: "DE" (case-insensitive).
Example prompts
Pull the latest annual report for Deutsche Bank AG and extract the iXBRL financial statements
List the directors of Volkswagen AG from Handelsregister
What's the legal shareholder structure of Allianz SE? (Note: not UBO — see notes)
Workflow
Step 1 — Resolve the entity
search_companies({ jurisdiction: "DE", query: "<name or ID>" })
get_company_profile({ jurisdiction: "DE", 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 Germany
- Post CJEU C-37/20 (Nov 2022) — the Transparenzregister (Germany's UBO register) became access-restricted to AML-obliged entities.
get_persons_with_significant_controlis not available for DE. Useget_shareholdersfor legal-shareholder data, but note shareholders ≠ beneficial owners. - Handelsregister filings are mainly iXBRL annual reports (Bundesanzeiger).
fetch_documentreturns raw bytes. - Court (Amtsgericht) prefixes the HRB number — region matters for disambiguation.
- Liechtenstein and Austria HRs are separate from this — see those skills.
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.
