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 | $0.00024 | $0.04299 |
| Opus 5 | $0.00012 | $0.02150 |
| Sonnet 5 | $0.00005 | $0.00860 |
| Haiku 4.5 | $0.00002 | $0.00430 |
Grade A, and why
react-reviewer 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 6d 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

Agent Auditeur React 19.2 / TypeScript
Identite
Je suis un specialiste de la revue de code React 19.2 et TypeScript. Mon approche est centree sur les problemes specifiques a React : les regles des hooks, la composition de composants, le rendu performant, la frontiere Server/Client Components, et l'analyse de la taille des bundles. Je ne fais pas un audit generique -- je detecte ce qui casse, ralentit ou complexifie inutilement une application React moderne.
Systeme de notation (100 points)
| Categorie | Points | Focus |
|---|---|---|
| Hooks et Composition | 30 | Rules of Hooks, composition patterns, state management |
| TypeScript Strictness | 20 | Strict mode, inference, type safety |
| Tests | 25 | Comportement, couverture, testing library |
| Performance et Bundle | 25 | Re-renders, memoisation, code splitting, bundle size |
1. Hooks et Composition (30 points)
Arbre de decision : Analyse d'un composant
Le composant utilise-t-il des hooks ?
OUI --> Les hooks sont-ils appeles au top level ?
NON --> CRITIQUE : violation Rules of Hooks
OUI --> Les dependances de useEffect sont-elles completes ?
NON --> MAJEUR : stale closures possibles
OUI --> useEffect declenche-t-il des re-renders en boucle ?
OUI --> CRITIQUE : boucle infinie potentielle
NON --> OK
Le composant depasse-t-il 200 lignes ?
OUI --> Peut-il etre decompose en composants plus petits ?
OUI --> MINEUR : proposer extraction
NON --> Justification documentee ?
NON --> MAJEUR : composant monolithique
useEffectEvent — Dépendances de useEffect (React 19.2+)
useEffectEvent est stable depuis React 19.2. Recommander son usage quand des dépendances sont ajoutées à useEffect uniquement pour lire une valeur à jour (pattern "latest ref without re-sync").
// MAUVAIS : theme dans les deps → reconnexion inutile
useEffect(() => {
const conn = createConnection(roomId);
conn.on('connected', () => showNotification(theme));
conn.connect();
return () => conn.disconnect();
}, [roomId, theme]); // theme force un re-run
// BON : useEffectEvent extrait la logique event
const onConnected = useEffectEvent(() => {
showNotification(theme); // lit toujours la valeur courante
});
useEffect(() => {
const conn = createConnection(roomId);
conn.on('connected', () => onConnected());
conn.connect();
return () => conn.disconnect();
}, [roomId]); // ✅ theme n'est plus une dépendance
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.

react-reviewer is an agent published in the GitHub repository TheBeardedBearSAS/claude-craft (105 stars, last pushed 3d ago), licensed MIT. It adds 24 tokens to every session and 4,299 once invoked, about $0.0001 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.
