Use when loading data in Start routes — isomorphic loaders, TanStack Query in a loader, mutations, or per-route SSR. Do NOT use for generic Router/Query API.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<objective> Covers what is specific to TanStack Start about data loading, on top of generic TanStack Router/Query (route trees, file-based routing, search-param validation, useQuery/useMutation mechanics, cache config — all covered instead by react-expert's react-tanstack-router): isomorphic loaders (server on first request, client on navigation), context.queryClient.ensureQueryData() inside a loader for SSR prefetch + hydration, the per-route ssr flag (true | false | 'data-only'), and mutations through server functions followed by router.invalidate(). Critical rules: never touch window/localStorage at loader top level (loaders run on the server too) — gate with ssr: false/'data-only' or useEffect instead; share one queryOptions factory between ensureQueryData (loader) and useQuery (component) so cache keys match; prefetch through the router-context queryClient, never a new one; invalidate loaders/Query cache after every server-function write; and remember ssr only tightens down the route tree, a child can never loosen a parent's ssr: false back to true. Includes templates for a Query-prefetching route and a selective-SSR route. …

How to install
mdr add fusengine/agents/start-routing-data@sha256:857b4e55f2819386The line at the top of this page pins the label git:20260729.3b91eed, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
