# new-agent.sh — genera el scaffold de un nuevo agente
#
# Uso:
#   ./dev-scripts/new-agent.sh <agent-id> [displayname]
#
# Ejemplo:
#   ./dev-scripts/new-agent.sh monitor-bot "Monitor Agent"
#
# Crea:
#   agents/<agent-id>/config.yaml     (basado en el assistant como plantilla)
#   agents/<agent-id>/agent.go        (reglas puras vacías, listo para extender)
#   agents/<agent-id>/prompts/        (directorio para system prompt)
#   agents/<agent-id>/data/           (directorio de datos, en .gitignore)
#
# También te recuerda los dos pasos manuales que quedan.
