+Skill SCRIPT — bibliothèque de scripts bash par agent.
+
+Chaque agent dispose de son propre dossier scripts/ (configurable via
+"scripts_dir" dans config.json, sinon /opt/<install_dir>/scripts).
+
+L'environnement du script expose automatiquement :
+  MQTT_BROKER, MQTT_PORT, MQTT_REPLY_TOPIC, AGENT_ID, SCRIPTS_DIR
+
+Ainsi un script peut publier son résultat directement :
+  mosquitto_pub -h $MQTT_BROKER -t $MQTT_REPLY_TOPIC -m "mon résultat"
+
+Usage LLM :
+  SKILL:script ARGS:list
+  SKILL:script ARGS:show <nom>
+  SKILL:script ARGS:save <nom> | <contenu>
+  SKILL:script ARGS:exec <nom> [args...]
+  SKILL:script ARGS:run | <contenu inline>
+  SKILL:script ARGS:delete <nom>
