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

gbizinfo-company-search 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.

What it actually says

When to use

Use this skill when:

  • The user provides a company name in any of these forms: Japanese kanji, katakana, hiragana, or Latin romanization (2+ characters).
  • You need to identify the 13-digit 法人番号 before pulling detailed data.

How to invoke

Call the kokai MCP server's search_company tool:

{
  "name": "search_company",
  "arguments": {
    "name": "<company name, 2+ chars>",
    "limit": 5
  }
}

The classifier accepts:

  • Japanese kanji (株式会社…)
  • Katakana (メルカリ など)
  • Hiragana (かわぐち など)
  • Latin (KAWAGUCHI / Mercari など)

Output format

For each candidate, present:

  • Company name
  • 13-digit 法人番号
  • Location (本社所在地)
  • Source URL (cite_required)

Confirm the candidate with the user before drilling deeper.

Boundary

  • Output is signal / 確認材料 / context — NOT a decision.
  • If multiple matches exist, present all and let the user disambiguate. Do not pick on their behalf.
Changes

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.
