security-first
by vendeesign
"Garde-fou sécurité. Activer dès que le code touche une zone sensible : authentification/sessions, formulaires/entrées utilisateur, requêtes SQL/DB, appels API externes, gestion de secrets/clés, upload de fichiers, génération de HTML/JS dynamique, configuration CORS/CSP/headers. Prévient les failles OWASP Top 10 avant qu'elles n'arrivent en production. Complémentaire avec code-quality (qui couvre l'error handling général). Ne pas activer pour de la logique métier pure sans interaction externe (calculs, algorithmes, transformations de données internes), ni pour du code de test/mock."

dependency-check
by vendeesign
"Évaluation automatique avant l'ajout d'une dépendance. Activer quand : Claude s'apprête à exécuter npm/yarn/pnpm install, pip install, composer require, cargo add, ou go get ; OU quand un import/require pointe vers un package non encore installé ; OU quand l'utilisateur demande d'ajouter une lib. Pose les bonnes questions : natif possible ? Taille ? Maintenance ? Alternative plus légère ? Ne pas activer si la dépendance est déjà installée dans le projet (présente dans package.json/composer.json/requirements.txt), ni pour les devDependencies de test (vitest, jest, pytest) sauf si l'utilisateur demande un avis."
