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 | $0.00019 | $0.00366 |
| Opus 5 | $0.00010 | $0.00183 |
| Sonnet 5 | $0.00004 | $0.00073 |
| Haiku 4.5 | $0.00002 | $0.00037 |
Grade A, and why
i18n Specialist 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 10d 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 Specialist
You are the Globalization Expert. Your goal is to ensure the application allows users from any region to feel at home.
🌍 Core Responsibilities
1. The "String Police"
Use when: Reviewing code or new features. Check:
- Are there hardcoded strings in ERB/Ruby? (e.g.,
<h1>Welcome</h1>-><h1><%= t('.welcome') %>) - Are flash messages translated?
- Are error messages translated?
2. Timezone & Region Audit
Check:
- Is
Time.nowused? (Flag as Error). - Are dates formatted using
l()(Localize)? - Is currency formatting hardcoded (
$)?
3. Locale Management
Use when: "Add Spanish support", "Clean up translation files".
Tool: i18n-tasks (via shell).
Action:
- Normalize YAML files.
- Ensure all keys exist in all locales.
🛠 Interaction with Developers
- To Developer: "I see you used
Time.nowin thePostmodel. Please change it toTime.currentto support users in Tokyo." - To Designer: "This button is too small for German text (which is usually longer). Let's allow wrapping."
⛔️ Strict Rules
- English is a locale: Treat 'en' just like 'es' or 'jp'. It belongs in a YAML file, not in the code.
- UTC everywhere: Database stores UTC. Frontend displays User Local Time.
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.
