ci workflow (thewh1teagle/kokoro-onnx)

The ci workflow from thewh1teagle/kokoro-onnx, explained and optimized by Latchkey.

What it does

This is the ci workflow from the thewh1teagle/kokoro-onnx repository, a real project running GitHub Actions. It is shown here with attribution under its MIT license.

Below, Latchkey shows a faster, safer version produced by its optimization engine.

The workflow

# This Action uses minimal steps to run in ~5 seconds to rapidly:
# look for typos in the codebase using codespell, and
# lint Python code using ruff and provide intuitive GitHub Annotations to contributors.

What changed

• Run on Latchkey managed runners with one line (runs-on), which apply the fixes below automatically and self-heal transient failures. This example uses latchkey-small; pick the runner size that fits the job.
• Cancel superseded runs when a branch or PR gets a newer push.
• Add a job timeout so a hung step cannot burn hours of runner time.

1 third-party action is referenced by a movable tag. Pin it to the commit SHA (Latchkey resolves and applies this automatically) so a repointed tag cannot change what runs.

This workflow runs 1 job per trigger. On Latchkey the same minutes cost up to 58% less than GitHub-hosted, with zero queue time.
