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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00036 | $0.01150 |
| Opus 5 | $0.00018 | $0.00575 |
| Sonnet 5 | $0.00007 | $0.00230 |
| Haiku 4.5 | $0.00004 | $0.00115 |
Grade A, and why
design-md-convention 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 7d 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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DESIGN.md — Convention Design System AI-Friendly
Convention inspirée de VoltAgent/awesome-design-md (55+ design systems populaires, concept Google Stitch).
Principe : un fichier DESIGN.md en markdown à la racine du projet sert de source de vérité pour les agents IA qui génèrent ou modifient l'UI. Pas de Figma, pas de JSON complexe, juste du texte lisible par humain et par LLM.
Pourquoi DESIGN.md ?
| Problème sans DESIGN.md | Solution avec DESIGN.md |
|---|---|
| IA génère des couleurs aléatoires | IA lit la palette définie |
| Incohérence spacing entre composants | IA applique l'échelle documentée |
| Typographie variable | IA utilise les tokens définis |
| Onboarding designer/dev lent | DESIGN.md = réponse unique |
| Dépendance à Figma pour chaque décision | Markdown versionné avec le code |
Structure recommandée
Un DESIGN.md contient 7 sections obligatoires :
- Principes visuels — ton, personnalité, do/don't
- Design tokens — couleurs, typographie, espacements, rayons, ombres
- Grille & layout — breakpoints, colonnes, gutters, container widths
- Composants — liste + variantes + règles d'usage
- Patterns d'interaction — hover, focus, active, disabled, loading
- Accessibilité — niveau cible (AA/AAA), contrastes, focus rings
- Références — lien vers Figma (optionnel), design system inspiré
Voir .claude/templates/DESIGN.md.template pour la structure complète.
Règles de rédaction
1. Concis et structuré
- Tableaux > prose
- Tokens > valeurs hardcoded
- Exemples concrets > théorie
2. Tokens nommés, pas valeurs brutes
❌ MAUVAIS
Primary button: background #3B82F6
✅ BON
| Token | Valeur | Usage |
|-------|--------|-------|
| `color.primary.500` | #3B82F6 | Boutons primaires, liens actifs |
| `color.primary.600` | #2563EB | Hover des éléments primaires |
3. Do / Don't explicites
### Boutons
**DO**
- Utiliser `button.primary` pour l'action principale d'un écran (1 max)
- Utiliser `button.secondary` pour actions secondaires
**DON'T**
- Jamais 2 boutons primaires sur le même écran
- Jamais de couleur custom hors palette
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.

design-md-convention is a skill published in the GitHub repository TheBeardedBearSAS/claude-craft (105 stars, last pushed 8d ago), licensed MIT. It adds 36 tokens to every session and 1,150 once invoked, about $0.0002 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 2026-09-03.
