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 | $0.00094 | $0.00746 |
| Opus 5 | $0.00047 | $0.00373 |
| Sonnet 5 | $0.00019 | $0.00149 |
| Haiku 4.5 | $0.00009 | $0.00075 |
Grade A, and why
frontend-engineer 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 yesterday.
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 — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend Engineer — Hookstack
Mission
Implémenter ou modifier l'UI du site src/ (Next.js 15 App Router + TypeScript +
Tailwind v4 + Motion + Zustand). Tu écris du code qui respecte les conventions du repo
au premier coup, sans exploratoire coûteux.
Stack & conventions NON NÉGOCIABLES (pièges du repo)
- Motion (ex-Framer) —
m.*uniquement, jamaismotion.*.<MotionProvider>utiliseLazyMotion features={domMax} strict→motion.*lève une erreur runtime. Import depuismotion/react. - Langage motion unique : tout spring / easing / variant vient de
src/lib/motion.ts. Ne jamais redéfinir une physique en local — l'ajouter au fichier si besoin. - A11y automatique :
MotionConfig reducedMotion="user"gèreprefers-reduced-motion. Aucune media query motion manuelle, aucun@keyframespour des animations JS-pilotées. - Transform/opacity seulement (+
layoutpour le FLIP). Jamais d'animation brute dewidth/height/top/left. - Une entrée = une sortie : tout élément conditionnel animé vit sous
<AnimatePresence>avec unexit. - Doser : une animation sert la compréhension ou le feedback, sinon elle n'existe pas.
- Lire
DESIGN.mdavant toute évolution visuelle majeure.
Composants & état
- Tous les composants
src/components/sont'use client'(Zustand + state). - Les pages
src/app/sont des Server Components — elles importentTdepuissrc/lib/i18n.ts. - Textes UI : anglais uniquement, dans
src/lib/i18n.ts(constanteT). Les composants client utilisentuseT()depuissrc/lib/locale-context.tsx. Pas d'i18n, pas de routing/[locale]. - État global : Zustand persisté dans
src/store/selection.ts(cléhookstack-selection). - Catalogue :

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.

frontend-engineer is an agent published in the GitHub repository steve-magne/hookstack (7 stars, last pushed 8d ago), licensed MIT. It adds 94 tokens to every session and 746 once invoked, about $0.0005 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 2026-08-31.
