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 | $0.00000 | $0.00443 |
| Opus 5 | $0.00000 | $0.00221 |
| Sonnet 5 | $0.00000 | $0.00089 |
| Haiku 4.5 | $0.00000 | $0.00044 |
Grade A, and why
i18n-mandatory 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 6d 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
i18n mandatory (binding)
You are editing UI code. Every user-visible string in JSX must go through t('namespace:section.key') from react-i18next. Never hardcode English strings in components.
Surfaces this rule covers:
- Labels, titles, descriptions.
- Placeholders.
- Button text.
- Table headers.
- Error messages.
- Empty states.
- Tooltips.
How to add a new key
- Add to all three locale files:
packages/control-plane-ui/src/i18n/locales/en/pages.json(orcommon.json/nav.json).packages/control-plane-ui/src/i18n/locales/zh/....packages/control-plane-ui/src/i18n/locales/es/....
- Copy to
packages/control-plane-ui/public/locales/{en,zh,es}/.... - Verify key counts match across all 3 locales:
npm run check:i18n
CI gate. Pre-merge required.
Technical terms
Stay in English across all locales: API, SSO, Provider, Model, Agent, Device, Hook, Token, mTLS, OAuth, PKCE, JWT, etc.
Forbidden
<button>Save</button> // ❌ hardcoded
<input placeholder="Email" /> // ❌ hardcoded
<h1>Dashboard</h1> // ❌ hardcoded
Correct
<button>{t('pages:settings.save')}</button>
<input placeholder={t('common:fields.email')} />
<h1>{t('pages:dashboard.title')}</h1>
Skipping this rule requires explicit user approval in chat.
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.

i18n-mandatory is a cursor rule published in the GitHub repository AlphaBitCore/nexus-gateway (23 stars, last pushed 4d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 443 tokens. 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.
