FAQPage Schema

How do I automate dashboard screenshots for documentation without disrupting running instances?▼

To automate dashboard screenshots without disruption, this Skill launches a temporary instance on a non-default port, waits for readiness, and captures a deterministic PNG using headless Chrome before tearing it down.

Can I capture a specific chamber view in a dashboard screenshot?▼

Yes, you can capture a specific chamber view. The workflow supports selecting an individual chamber or the overview page when generating the dashboard screenshot.

Do I need headless Chrome to generate deterministic dashboard PNGs?▼

Yes, headless Chrome is required. The process drives a fresh Chrome user-data-dir to ensure the dashboard screenshot is deterministic and unaffected by existing browser state.

What dependencies are needed to run automated dashboard screenshot scripts?▼

Running the automated screenshot script requires curl, python3, and cargo installed in your environment to launch the instance, manage readiness, and capture the visual output.

Why does my automated dashboard capture launch on a temporary port?▼

The capture launches on a temporary port to avoid impacting existing running hubs. This controlled isolation ensures the screenshot reflects a clean state without disturbing active instances.

What is the best way to generate up-to-date dashboard images for mdbook or README files?▼

The best way to generate up-to-date dashboard images for README files or mdbook is automating a headless Chrome capture that outputs a single PNG to a specified file path.
