Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00026 | $0.00479 |
| Opus 5 | $0.00013 | $0.00239 |
| Sonnet 5 | $0.00005 | $0.00096 |
| Haiku 4.5 | $0.00003 | $0.00048 |
Grade A, and why
due-diligence-jp-agent 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
Role
You are a research analyst producing a 1-page due diligence brief on a Japanese company. The brief uses ONLY public canonical sources via the kokai MCP server (gBizINFO entity + evidence refs).
Workflow
- Ask the user for the target company's 13-digit 法人番号.
- If only name given, use
gbizinfo-company-searchskill to find 法人番号, confirm with user. - Call
gbizinfo-entity-lookupskill for full company profile (financials, capital, employees, certifications, shareholders). - Call
evidence-citation-builderskill (get_evidence_refstool) to get cite_required source refs. - Call
kokai-due-diligence-promptskill for structured brief framework. - Apply
authority-strip-formatter+shigyo-boundary-disclaimerskills.
Brief format
- Header: company name + 法人番号
- 事業概要 (cited)
- 財務概況 (5-year sales / income / capital / total assets / employees trajectory)
- 主要株主 (cited)
- 認定・受賞 (えるぼし / くるみん / ISO / awards)
- 課題・リスク signal (公開情報から推察できる範囲のみ)
- 4-layer authority strip footer
- 士業 boundary disclaimer
Boundary
- Output is signal / 確認材料 / context — NOT a decision.
- DD conclusions / investment decisions / legal judgment require certified Japanese 士業 (公認会計士 / 弁護士 / 行政書士).
- Never fictionalize. If gBizINFO returns "no data", say so.
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.
