NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 1 finding, up to medium

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

medium Excessive Agency · line 59
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00151	$0.02059
Opus 5	$0.00076	$0.01030
Sonnet 5	$0.00030	$0.00412
Haiku 4.5	$0.00015	$0.00206

Security

Grade A, and why

vietnamese-business-comms 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.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/check_font_coverage.py, scripts/rules_business.py, scripts/validate_copy.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Vietnamese marketing and sales copy (vi-VN)

Campaign and outbound copy fails in two directions at once. It fails commercially by reading as a mass mailing — wrong pronoun, translated CTA, formal vocabulary where the market uses loanwords. And it fails legally, because Vietnamese advertising law regulates ordinary marketing enthusiasm: unproven superlatives, discounts over 50%, messages sent outside the legal window, and, from 01/01/2026, undisclosed influencer content.

Both failures are invisible to a fluency check. Every rule below exists to stop a specific one.

Step 1 — The channel picks the register, not the brand

Vietnamese has no neutral "you", and in this skill the choice is made by where the message lands rather than by the brand's usual voice.

Channel or genre	Register	Address
Zalo ZNS/ZBS template	`zns`	`Quý khách` — even for a brand that says `bạn` everywhere else
B2B cold email, quote, proposal, dunning	`b2b`	`anh/chị`, self as `em` or `tôi`
E-commerce, social, ads, push	`saas`	`bạn`
Mid-market services, consulting	`consult`	`anh/chị`
Press release	`press`	Institutional third person, `Quý vị` if anyone
Livestream script	`livestream`	`cả nhà`, `mọi người` — spoken register

bạn in B2B outreach is the single clearest tell of an automated send. No Vietnamese salesperson opens a cold email with Chào bạn.

Who you are in the sentence — em versus tôi, and why age outranks job title — references/b2b-xung-ho.md. The shared pronoun matrix: references/register-matrix.md.

Step 2 — Core rules (non-negotiable, no file hop needed)

Never bạn or mình in B2B outreach, a quote, or a dunning notice. anh/chị for them; em if you are plausibly junior, tôi otherwise.
Open with courtesy, not with the pitch. Vietnamese cold outreach puts a line of context before the ask. An English-style first-line value proposition reads rude.
Never write nhất, số 1, duy nhất, hàng đầu, bán chạy nhất as an unproven claim. Illegal under Điều 8 khoản 11 Luật Quảng cáo 16/2012/QH13, with current fines. bán chạy nhất is a ranking claim like any other.
A discount over 50% needs a registered chương trình khuyến mại tập trung. NĐ 81/2018 as amended by NĐ 128/2024. A headline number over 50 is a compliance question.
No marketing content in a transactional Zalo template. It gets the template rejected. ZNS/ZBS bodies cap at 400 characters có dấu.
Advertising messages need prior opt-in, a working opt-out, and the legal window — SMS 07:00–22:00, calls 08:00–17:00, ≤3 SMS and ≤1 call per number per 24h.
Use market vocabulary, not formal translations. Freeship, Deal, Voucher, Mua ngay. Học thêm means take extra classes and is never a CTA.
Never name a competitor in a comparison, and never use a person's image, name, or words without consent.
