vinext is a Vite plugin that provides the Next.js API surface so Next.js applications can run on Vite, with Cloudflare Workers as its primary deployment target. Developers use it to develop, build, and deploy applications using features such as routing, React Server Components, Server Actions, middleware, and static generation. The catalogue entries support migration and use of vinext.

SkillSpector: 9 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00072 | $0.02553 |
| Opus 5.5 | $0.00029 | $0.01021 |
| Sonnet 5.5 | $0.00014 | $0.00511 |
| Haiku 4.5 | $0.00007 | $0.00255 |
Grade A, and why
migrate-to-vinext scanned grade A with 1 finding 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
**IMPORTANT:** Do not use `getPlatformProxy()`, `getRequestContext()`, or custom worker entries with `fetch(request, env)` to access bindings. These are older patterns. `cloudflare:workers` is the recommended approach an How it starts
The opening of the file, as written. The whole thing — 217 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Migrate Next.js to vinext
vinext reimplements the Next.js API surface on Vite. Existing app/, pages/, and next.config.js work as-is — migration is a package swap, config generation, and ESM conversion. No changes to application code required.
FIRST: Verify Next.js Project
Confirm next is in dependencies or devDependencies in package.json. If not found, STOP — this skill does not apply.
Detect the package manager from the lockfile:
| Lockfile | Manager | Install | Uninstall |
|---|---|---|---|
pnpm-lock.yaml |
pnpm | pnpm add |
pnpm remove |
yarn.lock |
yarn | yarn add |
yarn remove |
bun.lockb / bun.lock |
bun | bun add |
bun remove |
package-lock.json or none |
npm | npm install |
npm uninstall |
Detect the router: if an app/ directory exists at root or under src/, it's App Router. If only pages/ exists, it's Pages Router. Both can coexist.

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.

migrate-to-vinext is a skill published in the GitHub repository cloudflare/vinext (9,263 stars, last pushed yesterday), licensed MIT. It adds 72 tokens to every session and 2,553 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
