+### Changed
+
+- **docs/resource-evaluations/agents-md-empirical-study-2602-11988.md** — Ajout section "Réception communautaire"
+  - Nuance clé : la commande `/init` génère un context file LLM-generated → -3% performance (pas "delete your CLAUDE.md")
+  - Lien vers post Charly Wargnier (LinkedIn, 72 reactions) comme exemple de simplification communautaire
+  - Note sur posts paraphrasant l'étude sans valeur ajoutée (ne pas citer comme sources indépendantes)
