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 | $0.00868 |
| Opus 5 | $0.00000 | $0.00434 |
| Sonnet 5 | $0.00000 | $0.00174 |
| Haiku 4.5 | $0.00000 | $0.00087 |
Grade A, and why
Ireland — CRO 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 11d 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.
Ireland — CRO Lookup
Live, direct-to-government access to Companies Registration Office (CRO) — An Oifig Chláraithe Cuideachtaí.
Single-country variant of the cross-border Cross-Border UBO Chain Walker. Use this skill when the user is explicitly focused on Ireland.
What you get
- Direct query to CRO. Every tool call hits Companies Registration Office (CRO) — An Oifig Chláraithe Cuideachtaí 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. 6-digit CRO number (e.g.
462571Apple Operations International Limited). - Sample entity: Apple Operations International Limited.
Available tools (jurisdiction = IE)
search_companies, get_company_profile, list_filings, get_document_metadata
For every tool, pass jurisdiction: "IE" (case-insensitive).
Example prompts
Find Apple Operations International Limited's CRO record
List the latest annual return filings for Google Ireland Limited
Confirm the company status of Stripe Payments Europe Limited
Workflow
Step 1 — Resolve the entity
search_companies({ jurisdiction: "IE", query: "<name or ID>" })
get_company_profile({ jurisdiction: "IE", 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 Ireland
- Ireland's RBO (Register of Beneficial Owners) is publicly accessible at https://rbo.gov.ie/ —
get_persons_with_significant_controlis on the roadmap. - Irish entities are often holding vehicles in cross-border tax structures (Double Irish, Irish DAC, etc.) — note the company type in profile.
- Filings are returned as PDF documents;
fetch_documentis on the roadmap for IE. Designated Activity Company (DAC)andPublic Limited Company (PLC)are the most common Irish corporate types.
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.
