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 | $0.00123 | $0.02672 |
| Opus 5.5 | $0.00049 | $0.01069 |
| Sonnet 5.5 | $0.00025 | $0.00534 |
| Haiku 4.5 | $0.00012 | $0.00267 |
Grade A, and why
internationalization 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 279 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Internationalization
Add languages and regions in a way that works for users, search engines, and the team maintaining the content. Stack-agnostic.
When to use
- Adding the first non-English (or non-default) language
- Adding additional locales to an existing internationalized site
- Choosing URL structure for languages
- Implementing hreflang tags
- Designing translation workflow
- Handling currency, date, time, and number formats
- Designing or fixing layout for RTL languages
- Auditing an internationalization rollout that's underperforming
When NOT to use
- Single-language site (use other skills)
- Domain strategy that's not language-driven (use
domain-strategy) - Content strategy independent of locale (use
content-strategy) - Marketing copy production (use
content-and-copy)
Required inputs
- The locales in scope (language + region, e.g.,
en-US,de-DE,fr-CA) - Business reason per locale (priority, audience size)
- Existing site architecture
- Translation resources (in-house, agency, AI-assisted, community)
- Content volume and update frequency
The framework: 5 layers
Internationalization touches everything. Five layers, each with their own decisions.
Layer 1: URL structure
How locales are reflected in URLs.
| Pattern | Example | When |
|---|---|---|
| ccTLD | example.de, example.fr | Strong country focus, distinct legal entities, willing to maintain separate domains |
| Subdomain | de.example.com, fr.example.com | Logical separation, willing to host separately, common for large sites |
| Subfolder | example.com/de/, example.com/fr/ | SEO equity unified, simplest to manage, default for most |
| URL parameter | example.com?lang=de | Avoid; weak SEO signal |
For most sites: subfolder is the default. Subdomain or ccTLD only when there's a specific reason (legal, infrastructure, or brand).
Within the chosen pattern, decide:
- Language only (
/de/) or language plus region (/de-de/,/de-at/,/de-ch/)? - Default locale: at the apex (
example.com) or in a folder (example.com/en/)?
What ships with it
2 files 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.

internationalization is a skill published in the GitHub repository rampstackco/claude-skills (976 stars, last pushed yesterday), licensed MIT. It adds 123 tokens to every session and 2,672 once invoked, about $0.0005 per session on Opus 5.5. 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.
