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 | $0.00000 | $0.00400 |
| Opus 5.5 | $0.00000 | $0.00160 |
| Sonnet 5.5 | $0.00000 | $0.00080 |
| Haiku 4.5 | $0.00000 | $0.00040 |
Grade A, and why
tanstack-query 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
TanStack Query (v5)
TanStack Query owns all server state (react.mdc). Depth: skill tanstack-query. Client SPA: ignore SSR, dehydrate, HydrationBoundary.
- Define queries with
queryOptions()insrc/services/worker-api/<feature>-query-options.tsnext to<feature>.ts, and reuse that object foruseQuery/useSuspenseQuery/queryClient.query/setQueryData; never inline{ queryKey, queryFn }at a call site. - Keys sit under the backend namespace, hierarchical (
['worker-api', …]) and JSON-serializable; promote to a key factory once a feature has several related queries. queryFndelegates tofetchJsonWithSchema, which forwardssignal, throws on non-OK, and validates with the shared Zod schema - neveras T.createQueryClientsetsretry: falseon purpose: a failure surfaces at once with its request id, and a query that should retry setsretryin its ownqueryOptions.- Mutations invalidate with
invalidateQueriesby default; the full optimistic ritual (cancelQueries→ snapshot →setQueryData→ rollback →invalidateQueries) only when needed. - Warm route loaders with
queryClient.query({ ...opts, staleTime: "static" });ensureQueryData/fetchQuery/prefetchQueryare deprecated since 5.102 (tanstack-router.mdc).
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.

tanstack-query is a cursor rule published in the GitHub repository louisbrulenaudet/monorepo-template (19 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 400 tokens. 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.
