Most of the time new tech just works out of the box. Occasionally it becomes a security research exercise.

CVEs requested. Millions of downloads impacted. Stay tuned.

Hey @ediri.de I just saw your Pulumi article:

Thank you for the glowing review of my monitoring-expert and kubernetes-specialist skills.

Happy to collaborate any time!

No they both load pretty quick, but most of the content is static so milage may vary.

My use case was serving individual llm friendly .md files in conjunction with human friendly html. Also added a button to toggle the .md view as a bonus.

Finally tried Astro + Starlight for a doc site. Serving HTML and Markdown concurrently was a breeze. The defaults are gorgeous and it just works. I see why everyone's moving here.

What are you using Astro for?

Cool to see my project getting international love! Next up: using the prompt engineer skill during the planning phase to craft tickets with instructions that auto-invoke the right skills during execution.

I've found writing custom slash commands that invoke skills to be the most helpful.

Claude Code is my daily driver. I've spent the last few months building out reusable workflows and finding the optimal human-in-the-loop balance. Still iterating but it's changed how I work.

This looks like a really well-architected skill. I hope this takes off.
