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 | $0.00068 | $0.00951 |
| Opus 5 | $0.00034 | $0.00476 |
| Sonnet 5 | $0.00014 | $0.00190 |
| Haiku 4.5 | $0.00007 | $0.00095 |
Grade A, and why
review-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 12d 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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Review TanStack Query
Review the TanStack Query setup in front-app (and its consumption of worker-api over HTTP) for alignment with current official best practices - query organization, cache correctness, and developer experience on a React 19 SPA. Your reply must be a plan of suggested changes: concise, actionable, structured - not only prose.
Invocation
Text after the slash command is additional scope/focus (e.g. "mutations", "cache invalidation") - narrow the review accordingly.
Ground truth (mandatory)
Your pre-trained knowledge of TanStack Query may be outdated. Do not draft suggestions from memory alone.
- Resolve "TanStack Query" via the Context7 MCP (
resolve-library-id→query-docs) at v5:queryOptionspattern,useSuspenseQuery/useInfiniteQueryguidance,placeholderData/initialDatasemantics, invalidation strategies,QueryClientdefaults. - Cross-check with local skill
.agents/skills/tanstack-query/SKILL.md. - For anything Context7 lacks, use Firecrawl search/scrape restricted to the official domain (
tanstack.com/query) - guides, reference, changelog for the installed minor. - Version currency: catalog entries (
@tanstack/react-query,-devtools) in pnpm-workspace.yaml vs latest stable; flag deprecated v4-era APIs still present (isFetchingmisuse aside - look for removed options). - Cite the retrieved source next to every finding; label anything unverifiable as Unverified.
Scope artifacts
- apps/front-app/src/services/ (fetchers +
queryOptionsdefinitions), apps/front-app/src/hooks/ QueryClientinstantiation/defaults and provider placement; router integration (loader ↔ queryClient)- Devtools wiring (
@tanstack/react-query-devtools, production gating) - Correlation-id header propagation from SPA to gateway (packages/correlation-id)
Analysis axes
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.

review-tanstack-query is a skill published in the GitHub repository louisbrulenaudet/monorepo-template (19 stars, last pushed 11d ago), licensed Apache-2.0. It adds 68 tokens to every session and 951 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings.
