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."

querying-logseq-data
by C0ntr0lledCha0s
Expert in building Datalog queries for Logseq DB graphs. Auto-invokes when users need help writing Logseq queries, understanding Datalog syntax, optimizing query performance, or working with the Datascript query engine. Covers advanced query patterns, pull syntax, aggregations, and DB-specific query techniques.
cartesian

This skill should be used when the user asks to "decompose a problem", "apply Cartesian method", "break this down systematically", "reduce to first principles", "analyze from the ground up", "apply methodical doubt", or wants to process input through Cartesian Reductionism to decompose complex wholes into clear, distinct parts.
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."
