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 | $0.00183 | $0.05558 |
| Opus 5 | $0.00092 | $0.02779 |
| Sonnet 5 | $0.00037 | $0.01112 |
| Haiku 4.5 | $0.00018 | $0.00556 |
Grade A, and why
hydrogen-storefront 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 9d 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 — 971 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hydrogen 2026 Storefront Framework
Hydrogen is Shopify's Remix-based framework for building fast, custom storefronts. This skill covers Hydrogen 2026 project setup, the Storefront API client, cart management with hooks, Customer Account API, caching strategies, Oxygen deployment, CLI commands, and real-world PDP and collection page patterns.
When Asked
When asked to scaffold a new Hydrogen storefront: Provide the npm create @shopify/hydrogen command, explain project structure, and show how to configure .env with Storefront API credentials.
When asked to fetch and display products: Use the Storefront API via the storefront client (GraphQL query), show how to load product details, variants, and media; explain caching strategies.
When asked to implement a shopping cart: Use createCartHandler for backend cart mutations, useCart hook for frontend state, and explain line item management, discounts, and checkout flow.
When asked about Customer Account API: Explain how to enable, authenticate with OAuth, and use for customer login, order history, account details, and profile updates.
When asked to optimize performance and caching: Discuss Cache-Control headers, Oxygen runtime caching, request coalescing, and streaming SSR; provide cache strategy examples.
When asked to deploy to Oxygen: Show CLI deployment steps (hydrogen deploy), environment variable setup, monitoring, and rollback procedures.
When asked to implement search or filtering: Use Hydrogen Search API, faceting, filtering by attribute, and show autocomplete and collection filter patterns.

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.
