What is content-sdk-loader-authoring?

A guide to writing content loaders in an Angular application. It explains where loaders live, how they access configuration and request details, how they return data, and how they are registered for use by routes.

It is for adding or debugging loaders that fetch Sitecore data, handle language and site variants, support editing previews, and report missing pages.

It prevents loaders from depending on Angular services in server code that may run without Angular's dependency-injection system. It also reduces errors caused by putting loaders in the wrong directory or forgetting their registry entry.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00028	$0.00406
Opus 5.5	$0.00011	$0.00162
Sonnet 5.5	$0.00006	$0.00081
Haiku 4.5	$0.00003	$0.00041

Security

Grade A, and why

content-sdk-loader-authoring 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 authoring (Angular)

Detail: AGENTS-loaders-and-di.md Read first: src/content-sdk/loaders/page.loader.ts, src/content-sdk/loaders/index.ts

When

Adding, changing, or debugging a loader
Any edit under src/content-sdk/
A component needs Sitecore data it does not currently receive

Rules

Loaders live in src/content-sdk/loaders/, never in src/app/
No inject(), no constructor DI, no Angular services in a loader body — loaders also run from plain Express middleware at POST /_data, where there is no injector
Get config and client by static import: scConfig from sitecore.config.ts, getClient() from ../client/sitecore-client
Get request state from the LoaderContext argument: getLanguage, getSiteName, getVariantId, getComponentVariantIds, getEditingPreviewData, splitLocaleFromPath
Register in the one LOADERS object; the key must match the loaderResolver('<key>') argument in app.routes.ts
Return JSON-serializable data — results cross TransferState
Signal not-found with throw new NotFoundNavigationError()

Stop

Stop if the task requires per-request Angular state that only DI can provide — surface the conflict instead of injecting into a loader
Stop if asked to move loaders under src/app/ or to maintain a second server-side loader set

Changes

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.
