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 | $0.00970 |
| Opus 5 | $0.00000 | $0.00485 |
| Sonnet 5 | $0.00000 | $0.00194 |
| Haiku 4.5 | $0.00000 | $0.00097 |
Grade A, and why
Belgium — KBO/BCE 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.
Belgium — KBO/BCE Lookup
Live, direct-to-government access to Crossroads Bank for Enterprises (CBE / KBO / BCE) — FOD Economie.
Single-country variant of the cross-border Cross-Border UBO Chain Walker. Use this skill when the user is explicitly focused on Belgium.
What you get
- Direct query to KBO/BCE. Every tool call hits Crossroads Bank for Enterprises (CBE / KBO / BCE) — FOD Economie 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. 10-digit Belgian enterprise number (e.g.
0403.201.185formatted,0403201185raw — Anheuser-Busch InBev SA/NV). - Sample entity: Anheuser-Busch InBev SA/NV.
Available tools (jurisdiction = BE)
search_companies, get_company_profile, get_officers, list_establishments
For every tool, pass jurisdiction: "BE" (case-insensitive).
Example prompts
Find Anheuser-Busch InBev's current bestuurders + all establishments
Confirm KBC Bank NV's enterprise number and registered office
List Solvay SA's establishment branches across Belgium
Workflow
Step 1 — Resolve the entity
search_companies({ jurisdiction: "BE", query: "<name or ID>" })
get_company_profile({ jurisdiction: "BE", 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 Belgium
- Belgium is bilingual — KBO (Dutch) and BCE (French) are the same register. Company names appear in both languages where applicable.
- Post CJEU C-37/20 — Belgium's UBO register is access-restricted.
get_persons_with_significant_controlreturns 501. list_establishmentsreturns the company's vestigingseenheden / unités d'établissement (branches) — useful for disentangling holding-vs-operating entities.- Officers data covers bestuurders / administrateurs (directors).
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.
