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 | $0.00000 | $0.00190 |
| Opus 5.5 | $0.00000 | $0.00076 |
| Sonnet 5.5 | $0.00000 | $0.00038 |
| Haiku 4.5 | $0.00000 | $0.00019 |
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 12d 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
Règle 09 : Internationalisation (i18n)
This skill provides guidelines and best practices.
See ../../rules/16-i18n.md for detailed documentation.
Message formatting
- ICU MessageFormat 2.0 (MF2) is a stable part of Unicode CLDR since CLDR 47 (March 2025). It replaces the legacy ICU MessageFormat (MF1,
{count, plural, one {…} other {…}}) for plurals, gender and selection. - MF1 is still what most frameworks ship (e.g. Symfony's
+intl-icutranslation domain): check library support before migrating, and do not mix both syntaxes in one catalogue. - Keep plural/gender logic inside the message, never in application code.
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 TheBeardedBearSAS/claude-craft (107 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 190 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 2026-09-03.
