Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

find-company 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.

What it actually says

Find Company

Confirm a company exists and capture its core identity. Stop there.

When to use

  • "Does X exist as a real company?"
  • "Is X still active?"
  • "What's the registry number for Acme Trading Ltd?"
  • "Verify this counterparty before I sign."

When NOT to use

  • Need directors → get-director-details
  • Need ownership → get-shareholder-details
  • Need financial figures → get-financials
  • Need filing history → get-filings

Example

Is "Tesla Limited" a real UK company?
Verify SIREN 552081317.

Workflow

1. If user gave a name:
     search_companies({ jurisdiction, query, limit: 5 })
     → pick the candidate whose status='active' and name best matches
     → if multiple plausible matches, surface them and ask the user to confirm

2. If user gave an ID, skip step 1.

3. get_company_profile({ jurisdiction, company_id })
     → capture company_name, status, status_detail,
       incorporation_date, registered_address

4. REPORT:
     - 1 line: "<name> (<jurisdiction>, <company_id>) is <status>, incorporated <date>."
     - Address on second line if user asked.
     - Cite the company_id verbatim.

Edge cases

  • Multiple matches: don't guess. Ask the user to confirm.
  • Dissolved: report as such; suggest get-filings or get-director-details if the user wants the historical view.
  • 501 from upstream: this jurisdiction isn't supported. Surface honestly.
  • Per-country ID format: differs per registry. Call list_jurisdictions({ jurisdiction: '<CC>' }) for the schema.

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.
