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 | $0.00065 | $0.01003 |
| Opus 5 | $0.00032 | $0.00502 |
| Sonnet 5 | $0.00013 | $0.00201 |
| Haiku 4.5 | $0.00006 | $0.00100 |
Grade A, and why
next-intl-routing-and-navigation 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.

Next Intl Routing and Navigation
Use this skill when the task is primarily about URL structure, locale negotiation, or locale-aware navigation.
Scope
- App Router locale routing setup
defineRouting,createMiddleware,createNavigationlocalePrefix,localeDetection,localeCookie,alternateLinks- localized pathnames, domains,
getPathname, and base-path-aware URL generation - locale switchers and CMS-driven localized URLs
Routing cues
defineRouting,createNavigation,Link,useRouter,usePathname,getPathname, locale switcher, domain routing, pathnames,proxy.ts,middleware.ts,NEXT_LOCALE,hreflang-> use this skill- ICU messages,
useTranslations,useFormatter, rich text, message validation -> usenext-intl-messages-and-formatting getRequestConfig,setRequestLocale,getTranslations, metadata, Server Actions, testing -> usenext-intl-server-runtime- plugin setup, TypeScript augmentation, Crowdin,
useExtracted, message loading strategy -> usenext-intl-workflows-and-tooling
Default path
- Read references/routing-architecture.md first.
- If the task touches locale switchers, cookies, alternate links, or
getPathname, read references/locale-switchers-and-alternate-links.md. - If the task touches localized slugs, domains, or SEO-facing URLs, read references/pathnames-domains-and-cms.md.
- Keep
routing.ts,proxy.tsormiddleware.ts, navigation helpers, and locale-switcher behavior derived from one shared routing object. - Validate any incoming locale with
hasLocale(...)before treating it as trusted.
When to deviate
- Disable or customize automatic alternate links when URLs vary outside the routing config or locale coverage differs.
- Use domain routing or CMS-driven slugs only when the app actually needs them.
- Move to server-runtime when the issue is request config or metadata rather than URL structure.
What ships with it
3 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.

next-intl-routing-and-navigation is a skill published in the GitHub repository andrewsrigom/agent-skills (2 stars, last pushed 5mo ago), licensed MIT. It adds 65 tokens to every session and 1,003 once invoked, about $0.0003 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 2026-08-31.
