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 | $0.00037 | $0.01076 |
| Opus 5.5 | $0.00015 | $0.00430 |
| Sonnet 5.5 | $0.00007 | $0.00215 |
| Haiku 4.5 | $0.00004 | $0.00108 |
Grade A, and why
nuxt4-patterns 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.
This is a copy
91% identical to nuxt4-patterns — 11 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Nuxt 4 Patterns
Use when building or debugging Nuxt 4 apps with SSR, hybrid rendering, route rules, or page-level data fetching.
When to Use
- Hydration mismatches between server HTML and client state
- Route-level rendering decisions such as prerender, SWR, ISR, or client-only sections
- Performance work around lazy loading, lazy hydration, or payload size
- Page or component data fetching with
useFetch,useAsyncData, or$fetch - Nuxt routing issues tied to route params, middleware, or SSR/client differences
Hydration Safety
- Keep the first render deterministic. Do not put
Date.now(),Math.random(), browser-only APIs, or storage reads directly into SSR-rendered template state. - Move browser-only logic behind
onMounted(),import.meta.client,ClientOnly, or a.client.vuecomponent when the server cannot produce the same markup. - Use Nuxt's
useRoute()composable, not the one fromvue-router. - Do not use
route.fullPathto drive SSR-rendered markup. URL fragments are client-only, which can create hydration mismatches. - Treat
ssr: falseas an escape hatch for truly browser-only areas, not a default fix for mismatches.
Data Fetching
- Prefer
await useFetch()for SSR-safe API reads in pages and components. It forwards server-fetched data into the Nuxt payload and avoids a second fetch on hydration. - Use
useAsyncData()when the fetcher is not a simple$fetch()call, when you need a custom key, or when you are composing multiple async sources. - Give
useAsyncData()a stable key for cache reuse and predictable refresh behavior. - Keep
useAsyncData()handlers side-effect free. They can run during SSR and hydration. - Use
$fetch()for user-triggered writes or client-only actions, not top-level page data that should be hydrated from SSR. - Use
lazy: true,useLazyFetch(), oruseLazyAsyncData()for non-critical data that should not block navigation. Handlestatus === 'pending'in the UI. - Use
server: falseonly for data that is not needed for SEO or the first paint. - Trim payload size with
pickand prefer shallower payloads when deep reactivity is unnecessary.
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.

nuxt4-patterns is a skill published in the GitHub repository Jamkris/everything-gemini-code (91 stars, last pushed 5mo ago), licensed MIT. It adds 37 tokens to every session and 1,076 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 91% identical to nuxt4-patterns, differing in 11 lines, and is treated as a copy.
