Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

geek-casino-cardputeradv 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 9d 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.

Silicon Casino — casino de poche pour M5Stack Cardputer ADV

Jeu de casino hors-ligne pour Cardputer ADV (ESP32-S3, 240×135, 56 touches, IMU BMI270, haut-parleur 1 W). Nom public acté : « Silicon Casino » (D-036) — « Casino » en toutes lettres pour la recherche M5Burner, le silicium pour l'identité maker. « Geek Casino » reste le nom de code du dépôt.

Garde-fous — non négociables sans décision explicite de Pierre

  • Jetons virtuels uniquement. Pas d'argent réel, pas d'achat, pas de compte, pas de réseau (ni WiFi ni BLE). C'est un jouet et un exercice d'animation, pas un produit de jeu d'argent.
  • Le joueur ne peut jamais être définitivement ruiné : renflouement automatique (voir décisions).
  • Aucune reprise de matière depuis Daoa Mini (palette, design system, lettermark, masques, corpus). La méthode oui, la matière non.
  • Chaque jeu porte l'identité geek. C'est une règle, pas une option : un jeu qui ressemble à n'importe quel casino n'a pas sa place ici. Deux façons de l'appliquer, selon ce que le geek touche :
    • Par le décor (chrome, dos de cartes, sérigraphie, cabinet) quand les éléments de jeu doivent rester lisibles — cartes du blackjack, numéros d'une roulette. Aucun réglage : c'est acquis.
    • Par les éléments de jeu eux-mêmes (symboles des rouleaux, faces de dés) quand le geek les remplace. Là, un réglage doit permettre de revenir au jeu classique : le joueur qui ne lit pas nos glyphes ne doit pas être exclu. Voir le réglage GLYPHS des machines à sous.

Rôles

Pierre est product owner, directeur visuel, testeur et décideur final. Claude Code est l'agent de développement principal — architecte, implémenteur, opérateur du simulateur, mainteneur de la documentation. La transparence sur ce point fait partie du produit (doctrine reprise de Daoa Mini) : le dépôt public le dit ici, l'appareil le dit dans son écran About (touche A à l'accueil), avec la distinction qui compte — construit AVEC une IA, mais rien d'IA ne tourne SUR l'appareil. Travail en petites étapes validées visuellement : simulateur d'abord, appareil ensuite. Toute hypothèse douteuse se tranche par une mesure ou un test, pas par une affirmation.

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.
