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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00115 | $0.01365 |
| Opus 5 | $0.00057 | $0.00682 |
| Sonnet 5 | $0.00023 | $0.00273 |
| Haiku 4.5 | $0.00012 | $0.00136 |
Grade A, and why
edinet-company-ir-tracker 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 — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to use
Use this skill when:
- The user provides a 法人番号 (13-digit) and you want to see if the company is listed + all their recent IR activity in one call.
- You're prepping for an M&A target call and need a fast cluster view of annual / quarterly / TOB / large-shareholding / governance disclosures.
- Investor / analyst use case: monitor a portfolio company's filings clustered by signal type.
- You want Kokai signal overlay (not raw EDINET timeline) — clustered into actionable groups instead of a flat list.
How to invoke
Call the kokai MCP server's get_edinet_company_disclosures tool:
{
"name": "get_edinet_company_disclosures",
"arguments": {
"corporateNumber": "<13-digit 法人番号>",
"edinetCode": "<E12345 form, alternative to corporateNumber>",
"lookbackDays": 30,
"limit": 50
}
}
corporateNumberORedinetCode(one required). If both,edinetCodewins (skips resolver).lookbackDays: default30, max90(auto-clamped). Phase 2 will extend to 365 once EDINET code master is imported.limit: default 50, max 100.

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.

edinet-company-ir-tracker is a skill published in the GitHub repository Kokai-Data/japan-business-data (2 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 115 tokens to every session and 1,365 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
