Actions define how the system communicates, processes information, and completes tasks. They are organized into four main categories: Message and Content Actions, which manage and format what the user sees; Destination Calls Actions, which connect the system to tools and external services; Conversation Flow and Memory Actions, which maintain context and guide the interaction; and AI Actions, which enable intelligent reasoning, content generation, and orchestration. Together, these action types describe how the system interprets requests and delivers effective, context-aware results.
