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 | $0.00061 | $0.00904 |
| Opus 5 | $0.00030 | $0.00452 |
| Sonnet 5 | $0.00012 | $0.00181 |
| Haiku 4.5 | $0.00006 | $0.00090 |
Grade A, and why
review-react 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 10d 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 — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Review React
Review the React 19 usage in front-app for alignment with current official React best practices - rendering patterns, data-fetching composition, and developer experience on a TanStack Router/Query SPA deployed via Cloudflare. 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. "hooks", "Suspense") - narrow the review accordingly.
Ground truth (mandatory)
Your pre-trained knowledge of React may be outdated. Do not draft suggestions from memory alone.
- Resolve "React" via the Context7 MCP (
resolve-library-id→query-docs): React 19 APIs (use, actions,refas prop, forwardRef changes), docs guidance on effects and fetching. - Cross-check with the local skill
.agents/skills/vercel-react-best-practices/SKILL.mdfor performance heuristics used by this repo. - For anything Context7 lacks, use Firecrawl search/scrape restricted to the official domain (
react.dev) - reference pages and blog posts for the installed major. - Version currency: catalog
react/react-dom/@types/react*in pnpm-workspace.yaml vs latest stable; flag removed/deprecated APIs still present in code. - Cite the retrieved source next to every finding; label anything unverifiable as Unverified.
Scope artifacts
- apps/front-app/src/ -
pages/,routes/,hooks/,components/,services/ - apps/front-app/package.json (React deps, plugins); devtools wiring (
@tanstack/react-devtools) - Tests under
apps/front-app/tests/(seefront-vitestskill for DOM harness conventions)
Analysis axes
- React 19 adoption: modern APIs used where they replace boilerplate (no unnecessary
forwardRef;usewith promises/Suspense where idiomatic); no legacy patterns kept out of habit. - Effects discipline: effects only for synchronization with external systems; no effect-based derived state or event logic; cleanup correctness.
- Data flow: server state in TanStack Query, URL state in router search params, ephemeral UI state in components - boundaries respected; no duplicated caches.
- Rendering & performance: memoization applied per current guidance (compiler-aware defaults, targeted
memo/useMemowhere proven needed); list keys stable; lazy/route-level code splitting aligned with/review-vitefindings. - Component hygiene: consistent component structure/naming per nested AGENTS.md; error and Suspense boundaries at route level; accessibility basics (semantics, labels).
- Version currency: types aligned (
@types/reactmajor matches runtime); devtools not leaking into production builds.
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-react is a skill published in the GitHub repository louisbrulenaudet/monorepo-template (19 stars, last pushed 9d ago), licensed Apache-2.0. It adds 61 tokens to every session and 904 once invoked, about $0.0003 per session on Opus 5. 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 2026-08-30.
