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 | $0.00087 | $0.00496 |
| Opus 5 | $0.00044 | $0.00248 |
| Sonnet 5 | $0.00017 | $0.00099 |
| Haiku 4.5 | $0.00009 | $0.00050 |
Grade A, and why
i18n 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 3d 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 Audit
Detection
Read package.json for i18n library:
react-i18next/i18nextnext-intlvue-i18nreact-intl(FormatJS)
Read locale files to understand key structure (e.g. src/locales/en.json).
Workflow
- Detect i18n library and locale file locations
- Search JSX/TSX/Vue files for hardcoded user-facing strings (see patterns.md):
- String literals in JSX:
<p>Hello world</p> - String props:
placeholder="Search...",label="Submit" aria-label="Close menu"
- String literals in JSX:
- Compare locale files — find missing keys between locales
- Report findings
Output format
Hardcoded strings (file:line):
src/components/Header.tsx:12 "Welcome back" → suggest key: header.welcomeBack
src/components/Form.tsx:34 placeholder="Search..." → suggest key: form.searchPlaceholder
Missing translations (key present in base locale but absent in others):
Key: dashboard.emptyState missing in: pt-BR, es
Key: errors.networkTimeout missing in: pt-BR
Rules
- Only flag user-visible strings (skip internal IDs, CSS classes, URLs, enum values)
- Suggest translation key names in camelCase matching project convention
- Never auto-modify locale files — report only
Error Handling
- If no i18n library detected → report project may not use i18n; still list any hardcoded strings found
- If no locale files found → skip missing-key comparison; only report hardcoded strings
- If locale files are not JSON (e.g.
.po,.yaml) → read them anyway and adapt key comparison logic
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 is a skill published in the GitHub repository helderberto/agent-skills (14 stars, last pushed 5d ago), licensed MIT. It adds 87 tokens to every session and 496 once invoked, about $0.0004 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.
