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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00081 | $0.01852 |
| Opus 5 | $0.00041 | $0.00926 |
| Sonnet 5 | $0.00016 | $0.00370 |
| Haiku 4.5 | $0.00008 | $0.00185 |
Grade A, and why
design-critique 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.

Design Critique
Workflow
1. Contexte et périmètre (avant tout)
Identifier avant de commencer :
- Cible utilisateur (consumer grand public / B2B / développeurs / seniors)
- Plateforme (web desktop, mobile native iOS/Android, tablette, TV)
- Stade du projet (wireframe, maquette haute-fidélité, produit live)
- Contraintes connues (charte graphique imposée, dark mode requis, accessibilité légale RGAA/WCAG)
2. Première impression — les 5 secondes
Répondre à ces trois questions sans réfléchir :
- Qu'est-ce que ce produit fait ?
- À qui s'adresse-t-il ?
- Quelle action suis-je censé faire maintenant ?
Si l'une des réponses est floue → problème de clarté à signaler en priorité.
3. Hiérarchie visuelle
Vérifier avec le test du "blur" (défocaliser mentalement l'écran) :
| Niveau | Signal attendu | Anti-pattern |
|---|---|---|
| H1 — titre principal | Largest element, bold | Plusieurs éléments de même poids |
| CTA principal | Couleur contrastante, seul de son type | Deux boutons primaires côte à côte |
| Body content | Lisible, subordonné au titre | Même taille que les titres |
| Metadata / labels | Réduit, discret | Trop proche du corps |
4. Typographie — critères mesurables
Taille corps : ≥ 16px (mobile ≥ 14px uniquement pour labels)
Line-height body : 1.4 – 1.6
Longueur de ligne : 45 – 75 ch (CSS: max-width: 75ch)
Nombre de fontes : ≤ 2 (une pour les titres, une pour le corps)
Contrastes de taille : H1/body ratio ≥ 2x
Outil de vérification rapide : https://typescale.com (générer la scale et comparer).
5. Couleurs et contraste WCAG
Seuils obligatoires :
| Contexte | Ratio minimum (AA) | Ratio idéal (AAA) |
|---|---|---|
| Texte normal | 4.5:1 | 7:1 |
| Texte large (≥ 18px bold) | 3:1 | 4.5:1 |
| Éléments UI (bordures, icônes) | 3:1 | — |
Outil : npx color-contrast-checker ou https://webaim.org/resources/contrastchecker/
Vérifier aussi :
- Mode daltonisme (deuteranopie) : ne jamais coder une info par la couleur seule → toujours ajouter icône ou label.
- Dark mode : tester avec
prefers-color-scheme: darksi applicable.
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-critique is a skill published in the GitHub repository khalilbenaz/claude-skills-collection (22 stars, last pushed 19d ago), licensed MIT. It adds 81 tokens to every session and 1,852 once invoked, about $0.0004 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.
