content-sdk-loader-cache-and-revalidation

content-sdk-loader-cache-and-revalidation is a skill for Claude Code, Codex from Sitecore/content-sdk. It costs 29 tokens per session (449 once invoked), scanned A, original, Apache-2.0.

A guide to server-side caching for content-loader results in an Angular application. It explains stale-while-revalidate behavior, cache keys, storage, and a request endpoint used to refresh cached content.

In plain words
What is it for?
It is for configuring loader caching, changing cache refresh timing, choosing storage behavior, and troubleshooting revalidation after content updates.
Why use it?
It helps prevent users from seeing outdated content after publishing and avoids incorrect cache sharing between sites, languages, or personalization variants. It also clarifies which preview and redirect requests should bypass caching.

Token cost

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.

Security

Grade A, and why

content-sdk-loader-cache-and-revalidation 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.

What it actually says

Loader cache and revalidation (Angular)

Detail: AGENTS-loaders-and-di.md#loader-cache Read first: src/server.ts, sitecore.config.ts

When

  • Stale or missing content after a publish
  • Tuning caching, revalidation, or the storage driver

Rules

  • Angular has no framework ISR — this app caches loader results via createLoaderCache on top of unstorage
  • One cache instance shared by createSitecoreRevalidateMiddleware, createLoaderDataServiceMiddleware, and angularApp.handle(req, { cache, req, res })
  • Configure by editing sitecore.config.ts and passing the values in the first argument of defineConfig: defineConfig({ angular: { loadersCache: { enabled: true, revalidate: 300 } } }, environment). scConfig.angular.loadersCache is the resolved read path used by src/server.ts — do not assign to it
  • Both fields default when omitted (enabled: true, revalidate: 300); per-route overrides via loaderResolver('page', { enabled, revalidate, tags })
  • Cache keys include site, locale and personalization variant — do not drop any of them
  • Editing and preview requests bypass the cache; redirects are never cached
  • unstorage and the cache are server-only — never import them from src/app/**
  • In production use a driver backed by shared storage; a per-process memory map is inconsistent across workers
  • Protect POST /api/revalidate with SITECORE_REVALIDATE_SECRET

Stop

  • Stop if a change would make the cache reachable from the browser bundle or cache personalized/editing responses
