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 | $0.00028 | $0.02798 |
| Opus 5 | $0.00014 | $0.01399 |
| Sonnet 5 | $0.00006 | $0.00560 |
| Haiku 4.5 | $0.00003 | $0.00280 |
Grade A, and why
shopify-hydrogen 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 8d 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.

Shopify Hydrogen
Overview
Hydrogen is Shopify's official React-based framework for building headless storefronts, built on top of Remix and deployed to Oxygen (Shopify's edge hosting). It provides first-class primitives for the Storefront API — product queries, cart management, customer accounts — alongside Shopify-specific components and hooks that handle caching, streaming, and SEO automatically. This skill covers scaffolding a Hydrogen project, querying the Storefront API, implementing cart functionality, and deploying to Oxygen.
When to Use This Skill
- When building a custom Shopify storefront with full design and UX control
- When the default Shopify Online Store theme is too limiting for your design requirements
- When you need server-side rendering, streaming, and edge-deployed performance
- When integrating third-party services (loyalty, CMS, personalization) directly into the storefront
- When you want a Shopify-managed backend with a completely custom frontend stack
Prerequisites & Platform Notes
This skill is written for custom/headless storefronts (Node.js, Python, or similar backend). The code examples use TypeScript/Node.js and can be adapted to any stack.
Shopify: Shopify Hydrogen is Shopify's headless framework. MACH/composable patterns apply when using Shopify as the commerce backend with a custom frontend, or when mixing Shopify with other best-of-breed services. WooCommerce: WooCommerce can serve as a headless backend via its REST API and WPGraphQL. These patterns apply when decoupling the frontend from WordPress. Magento: Magento's GraphQL API and PWA Studio support headless architectures. These composable patterns apply to Magento as a backend service in a MACH stack.
You'll need:
- Node.js 18+ (or adapt to your backend language)
- Redis for caching/queues
- An email sending service (SendGrid, AWS SES, or Postmark)
- CDN (Cloudflare, CloudFront, or Fastly)
Core Instructions
- Scaffold a Hydrogen project

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.
