Can I use Queries to modify the state of a workflow?

No, Queries are strictly read-only. They are designed for inspecting current workflow state and should never perform I/O or modify any internal variables.

When should I use SignalWithStart?

Use SignalWithStart when you want to send a signal to a specific Workflow ID but aren't sure if it's currently running. It will either signal the existing workflow or start a new one and deliver the signal immediately.

What is the difference between a Signal and an Update in Temporal?

Signals are asynchronous, fire-and-forget messages used to mutate workflow state without a return value. Updates are synchronous request-response mutations that include a validator and return a result to the caller.

Does this skill provide CLI examples for Temporal?

Yes, it includes standardized Temporal CLI commands for signaling, querying, and updating workflows directly from the terminal alongside the Go SDK implementations.

API Development

Implements robust messaging patterns for Temporal workflows using Signals, Queries, and Updates for distributed systems.

This skill provides comprehensive guidance and implementation patterns for managing communication with running Temporal workflows in Go. It enables developers to master asynchronous Signal handlers for fire-and-forget events, synchronous Queries for read-only state inspection, and the modern Update pattern for request-response mutations. By providing standardized code snippets for SignalWithStart, buffered signal processing, and validator-backed updates, this skill helps ensure reliable message passing and state management in complex, long-running business processes.
