Temporal Signals for Automated Coordination#

In Temporal Signals for Manual Interaction, you learned how external systems and humans send signals to running workflows. Signals are not limited to human input. They are a general-purpose communication channel between workflows, and they become powerful coordination primitives when workflows signal each other programmatically.

This article covers automated signal patterns: cross-workflow signaling, distributed mutexes built on signals, blocking semantics, and the anti-patterns that will burn you.

Multi-Agent Coordination#

A single agent can read files, call APIs, and reason about results. But some tasks are too broad, too slow, or too dangerous for one agent to handle alone. Debugging a production outage might require one agent analyzing logs, another checking infrastructure state, and a third reviewing recent deployments – simultaneously. Multi-agent coordination is how you split work across agents without them stepping on each other.

The hard part is not spawning multiple agents. The hard part is deciding which coordination pattern fits the task, how agents share information, and what happens when they disagree.
