Skill SCRIPT — créer et exécuter un script bash, avec renvoi du résultat via MQTT.
L'environnement du script expose automatiquement :
MQTT_BROKER, MQTT_REPLY_TOPIC, AGENT_ID
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:delete <nom>
