Vercel Shop is a monorepo, meaning one code repository that contains multiple related applications and tools, for a Next.js Shopify storefront template, its documentation site, and a scaffolding CLI. It helps developers create and work with Shopify storefronts built on Next.js. The catalogue entries are skills, commands, a plugin, and an instruction for working with this project.

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 | $0.00069 | $0.02962 |
| Opus 5.5 | $0.00028 | $0.01185 |
| Sonnet 5.5 | $0.00014 | $0.00592 |
| Haiku 4.5 | $0.00007 | $0.00296 |
Grade A, and why
build-shop 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 11d 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 — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build with Vercel Shop
Build the shop around commerce truth first: what product or collection is being shown, what the customer has selected, what can be bought now, what price is authoritative, and what state belongs in the URL, Shopify, the server cache, or the browser. Use Vercel Shop's template as the reference implementation, but adapt the behavior to the current storefront instead of copying files blindly.
Ground the work in source
- Read the project's
AGENTS.md, the target route, its view contract, and every operation it calls. - If the Vercel Shop template source is available, inspect it before relying on this prose:
- Template rules:
AGENTS.md - Route/layout shell:
app/layout.tsx,app/page.tsx - Shopify boundary:
lib/shopify/storefront/server.ts,lib/shopify/operations/,lib/shopify/transforms/,lib/product/types.ts,lib/customer/types.ts - Next.js cache boundary:
lib/<domain>/server.tscachedget*wrappers around the uncachedfetch*operations - Shared UI layout primitives:
components/ui/container.tsx,components/ui/page.tsx,components/ui/sections.tsx - Public source fallback: template source
- Template rules:
- Use the docs to orient before editing unfamiliar areas:
- Read the local Next.js documentation under
node_modules/next/dist/docs/for any API being changed. This template may use newer Cache Components and prefetch behavior than model knowledge. - Preserve existing cache directives, promises, invalidation tags, auth gates, redirects, metadata, and
notFound()behavior unless the task explicitly changes the domain behavior.
Hydrogen ownership
The template uses the framework-agnostic Hydrogen preview SDK, not Hydrogen's React Router application framework. Next.js owns routing, rendering, public-data caching, and invalidation. Hydrogen owns commerce state and protocols; the template supplies presentation and framework adapters. Use Hydrogen's cart provider/forms/handlers rather than rebuilding cart state or hydration. Cart types are handler-derived; catalog/account presentation uses domain transforms. Read the installed SDK guidance and verify adapter behavior before changing these boundaries.
What ships with it
9 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.

build-shop is a skill published in the GitHub repository vercel/shop (126 stars, last pushed 5d ago), licensed MIT. It adds 69 tokens to every session and 2,962 once invoked, about $0.0003 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 2026-09-26.
