 """
-Skill SCRIPT — créer et exécuter un script bash, avec renvoi du résultat via MQTT.
+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_REPLY_TOPIC, AGENT_ID
+  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:run | <contenu du script>
-  SKILL:script ARGS:save <nom> | <contenu>
-  SKILL:script ARGS:exec <nom> [args]
   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>
