Wake, Notify, and Steer Long-Running Agents with Signals

This workshop covers building long-running agents that receive new instructions and context in real time using Mastra Signals. Signals let user follow-ups, background task results, and external events enter the agent’s ongoing loop to wake idle threads or steer active runs.
