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.

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 | $0.00190 | $0.01722 |
| Opus 5.5 | $0.00076 | $0.00689 |
| Sonnet 5.5 | $0.00038 | $0.00344 |
| Haiku 4.5 | $0.00019 | $0.00172 |
Grade A, and why
sfnext-state-management 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 15d 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Storefront Next State Management
Server state lives in loaders and actions. Client state is small and local. There is no global client store library in the template (Zustand was removed): use the tools below in this order. docs/README-STATE.md and docs/README-DATA.md in your project cover each in depth.
Decision table
| State | Use |
|---|---|
| Data from SCAPI | loader + loaderData; action for writes |
| Another route's loader data | useRouteLoaderData('routes/_app') (route id = file path without extension) |
| Filters, sort, pagination, tab | URL: useSearchParams / useParams (shareable, SSR-friendly) |
| Must survive requests, read by server | cookies (createCookie from @/lib/cookie-utils.server) or session helpers |
| Pending or optimistic result | fetcher.formData, useNavigation, useOptimistic |
| Form fields, toggles, open/close in one component | useState / useReducer |
| Shared by a subtree | React context with a provider at the owning layout |
| Shared app-wide and read outside React, or high-frequency | module-level useSyncExternalStore store |
| Request-scoped server values (site, auth, basket) | router context (middleware), read with context.get(...) |
Prefer the earliest row that works. Never copy loader data into useState to "cache" it.
Existing providers and stores
| Need | API |
|---|---|
| Basket | BasketProvider in src/providers/basket.tsx: useBasket({ autoLoad }), useBasketSnapshot, useBasketHydrated, useBasketError, useBasketUpdater, useBasketReset, useBasketLoader, useBasketReconcile; BasketCookieReconciler syncs the cookie |
| Session info | useAuth() from @/providers/auth |
| Product / variant selection | @/providers/product-context, @/providers/product-view |
| Image widths | DynamicImageProvider (@/providers/dynamic-image) |
| Wishlist | src/providers/wishlist.ts (module-level store) |
| Mini-cart open state | useMiniCartStore, setMiniCartOpen in src/hooks/mini-cart-store.ts |
| Cart toast | src/hooks/cart-mutation-toast-store.ts |
| Shopper context | useShopperContext (@/hooks/use-shopper-context) |
What ships with it
2 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.

sfnext-state-management is a skill published in the GitHub repository SalesforceCommerceCloud/b2c-developer-tooling (56 stars, last pushed today), licensed Apache-2.0. It adds 190 tokens to every session and 1,722 once invoked, about $0.0008 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 2026-09-03.
