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 | $0.01570 | $0.01570 |
| Opus 5 | $0.00785 | $0.00785 |
| Sonnet 5 | $0.00314 | $0.00314 |
| Haiku 4.5 | $0.00157 | $0.00157 |
Grade A, and why
atelier-studio CLAUDE.md 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 today.
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 — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Atelier Studio — règles pour agents
App macOS Tauri 2 : chat multi-agents (CLIs claude/codex/grok/opencode/kimi via backend Rust atelier-studio-server — le sidecar chat Node est retiré, plan 065 phase A) + atelier scientifique (galerie, éditeurs, PDF, browser, terminal). Utilisateur : Thierry (MSc glaciologie).
Système de design — CONTRAIGNANT
Style sobre strict : jamais d'emojis colorés dans l'UI, icônes = SVG monochromes fins (stroke 1.3–1.5), pas de gradients décoratifs.
Toute valeur visuelle vient des tokens — ne jamais inventer de valeur locale :
- Tailles de texte : 10 / 11 / 12 / 13 / 15 px uniquement (
--fs-xsà--fs-xlsi définis). Pas de 9px, 12.5px, 14.5px. - Poids : 400 (corps), 500 (accent léger), 600 (titres). Rien d'autre.
- Rayons : 6px (contrôles), 10px (cartes/panneaux/menus), 999px (pilules). Rien d'autre.
- Espacement : multiples de 4 (4/8/12/16/20/24). Paddings de panneaux : 16 ou 20.
- Gris de texte : 4 niveaux —
--fg(contenu),--fg2(secondaire fort /--text-secondary),--muted(secondaire /--text-muted),--muted2(éteint /--text-disabled). Ne pas multiplier les gris au-delà. - Profondeur : surfaces élevées (menus, popovers, modales) = fond + ombre douce (
0 4px 16px rgba(0,0,0,.25)env.), pas une bordure de plus. Bordures 1px réservées aux séparateurs internes. - Typo :
letter-spacing:-0.01emsur les titres ;font-variant-numeric:tabular-numssur tout chiffre aligné (heures, tailles, compteurs) ; interligne 1.5 corps, 1.3 titres. - Motion : tout changement d'état visible transitionne en 120–150ms (opacity/transform). Jamais plus de 200ms. Respecter
prefers-reduced-motion. - Thèmes : toute couleur passe par les variables CSS — jamais de hex en dur dans un composant (exceptions existantes : sémantique ok/warn/erreur documentée dans App.css).
- Boutons : jamais de
<button>nu horssrc/components/ui/etsrc/components/shadcn/— utiliserButton(action textuelle),IconButton(icône seule) ouRowButton(rangée/chip/cellule/swatch/trigger cloné ; transmet ref et tous attributs natifs). Verrouillé parcss-contract.test.ts. - Menus contextuels et déroulants : jamais de menu fait main. React →
DropdownMenu/ContextMenu/Popoverdesrc/components/ui/(shadcn) ; galerie et éditeurs → la classe.menudu template (.mipour les rangées). Modèle commun : fond--bg-pop/--card, aucune bordure, ombre--elev, rayon 10 (conteneur) / 6 (rangées), rangées 12 px poids 400, survol--bg-ctl/--card2, sélection = ✓ SVG à droite, destructif =--status-error, ouverture au clic (jamais au survol), 120-150 ms. Verrouillé parcss-contract.test.ts(motifs*menu*,*pop*,*dropdown*) etgallery/server/tests/theme_contract.test.mjs. - Échelles Tailwind snappées : dans
src/styles/shadcn.css,--radius-sm/md→6px,--radius-lg/xl→10px,--text-xs→12px,--text-sm→13px — les classes nomméesrounded-*/text-xs/smrestent donc dans le système, même dans du code généré par le CLI shadcn. Ombres d'overlay viashadow-[var(--elevation-overlay)], voile de modale viabg-[var(--scrim)](verrouillé aussi).
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.
