setup-matrix

Conditionally skipping matrix entries in GitHub Actions is tedious — you'd need to add a skip step before each action in the job. This action solves that by filtering the matrix up front, so you can for example, use a workflow dispatch input to run only a single target. This action lets you define your matrix once in a YAML file exactly how you would in the workflow.

This is useful when QA or another department needs a specific platform build and running the full matrix is expensive. It's less relevant for open source projects where runners are free and there's no QA department.
