This is the Personal Unsigned Build workflow from the jgraph/drawio-desktop repository, a real project running GitHub Actions. It is shown here with attribution under its Apache-2.0 license.
Below, Latchkey shows a faster, safer version produced by its optimization engine.
The workflow
workflow (.yml)
name: Personal Unsigned Build
# Manually-triggered, unsigned build for personal forks.
# See doc/BUILDING_FOR_PERSONAL_USE.md.
#
# Needs no repository secrets: signing and notarization are skipped
# (DRAWIO_UNSIGNED), auto-update is disabled so the app keeps your
# changes, and nothing is published - the installers are attached to
# the workflow run as a downloadable artifact.

What changed
- Cache dependency installs on the setup step so they are served from cache.
- Add a job timeout so a hung step cannot burn hours of runner time.
What Latchkey heals here
This workflow has steps that commonly fail on transient issues (network, registries, flaky browsers). On Latchkey managed runners they are detected, retried, and self-healed instead of failing your build:
- Dependency installs
This workflow runs 1 job per trigger. On Latchkey the same minutes cost up to 58% less than GitHub-hosted, with zero queue time.
