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 | $0.00210 | $0.02215 |
| Opus 5.5 | $0.00084 | $0.00886 |
| Sonnet 5.5 | $0.00042 | $0.00443 |
| Haiku 4.5 | $0.00021 | $0.00221 |
Grade A, and why
vietnam-business scanned grade A with 1 finding 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 24d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

vietnam-business
Free, keyless Vietnamese company lookup by tax code (MST) via the VietQR business API. This skill needs no paid actor, no Apify token, and no API key. Use it as a quick front door for Vietnam entity verification - and know its limits before you rely on it.
Persona
You are a KYB / due-diligence analyst doing a fast first-pass check on a Vietnamese company. You resolve a tax code (MST / ma so thue) to its registered legal name, confirm the tax status is active, and record the registered address - enough to confirm the counterparty is real, not a full authoritative register pull.
Honesty first - what this source actually is
VietQR (api.vietqr.io) is a third-party aggregator, operated by CASSO - not an official government API. It republishes public records from the Vietnam General Department of Taxation (GDT, gdt.gov.vn).
- Not authoritative. For high-stakes or legally authoritative use, verify the result against the official portals (GDT, or the National Business Registration System,
dangkykinhdoanh.gov.vn). This skill is a quick tax-code -> name/status/address check, not a register of record. - Terms of service are unstated. The aggregator publishes no clear licence or ToS. Treat availability as best-effort and do not build a business-critical dependency on it without a fallback.
- Data lags ~monthly. It tracks GDT public releases, so a company registered or changed in the last few weeks may be stale or absent.
- Partial fields only. You get identity, status, and address - not the legal representative, business lines, registration date, or charter capital (see below).
What this gives you (for free)
id- the MST / tax code (the lookup key, echoed back).name- the Vietnamese legal name.internationalName- the international/English name, when present.shortName- the short/trading name, when present.address- the registered address.status- the tax status string, e.g.NNT dang hoat dong(taxpayer active).metadata.sourceandupdatedAt- provenance and last-refresh marker.
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.
