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.

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 | $0.00156 | $0.02031 |
| Opus 5 | $0.00078 | $0.01015 |
| Sonnet 5 | $0.00031 | $0.00406 |
| Haiku 4.5 | $0.00016 | $0.00203 |
Grade A, and why
vietnamese-tech-writing 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.

Vietnamese engineering and product writing (vi-VN)
Vietnamese technical writing fails differently from Vietnamese marketing writing. Marketing copy goes wrong by being too literal. Technical copy goes wrong by being too Vietnamese — translating the English terms that Vietnamese engineers keep in English, and addressing a reader in documents that describe a system.
Both defects are invisible to a non-engineer proofreader and instantly obvious to the team that has to use the document.
Step 1 — Decide what the document is before writing a word
Two decisions follow from the document type, and both are inverted from the landing-page defaults.
| If you are writing | Register | Terms |
|---|---|---|
| RFC, design doc, postmortem, runbook, spec | impersonal — no bạn at all |
Vietnamese leans formal (bộ nhớ đệm, cơ sở dữ liệu) |
| README, tutorial, API docs, UI copy, release notes | bạn |
Vietnamese for user-facing nouns |
| PR description, code review, standup, chat | mình / no address |
English terms throughout |
| Status page (customer-facing) | quý khách |
plain, non-technical |
bạn in an RFC is a defect. Vietnamese has natural impersonal constructions —
Hệ thống sẽ tự động retry, Cần cấu hình biến môi trường — and English does not, which is
exactly why translated text is full of bạn.
Which document takes which register, and the impersonal constructions that replace bạn:
references/doc-registers.md. The full pronoun matrix shared
with the other Vietnamese skills: references/register-matrix.md.
Step 2 — Core rules (non-negotiable, no file hop needed)
- Keep the English terms English.
deploy,commit,merge,bug,server,cache,deadline,sprint,backlog,pull request. Translating them is the single loudest machine-translation tell.cam kếtforcommitis the worst offender — it is a real word meaning to pledge. - Never translate environment names.
production,staging,dev.triển khai đến sản xuấtis not a sentence any Vietnamese engineer has written. - Identifiers, branch names, and commit subjects are ASCII. No diacritics, ever. The commit body may be Vietnamese; the subject line may not.
- Emit NFC Unicode. Precomposed
ế(U+1EBF). NFD breaks font rendering, inflates character counts past platform limits, and defeats search. - Vietnamese has no grammatical plural. ICU messages take
otheronly. Aone,few,manyorzerobranch in avifile is always a bug.=0selectors are fine. - Pick one tone-mark style per document — kiểu mới (

- Errors say what happened and what to do. Never

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.

vietnamese-tech-writing is a skill published in the GitHub repository trussary/vietnamese-language-skill (77 stars, last pushed 8d ago), licensed MIT. It adds 156 tokens to every session and 2,031 once invoked, about $0.0008 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 2026-08-30.
