One suggestion for improvement: Add some more info to your website/GitHub about the need for a provider and which providers are compatible. It took me a bit to figure that out because there was no prominent info about it. Additionally, none of the demos showed a login or authentication part. To me, it seemed like the VMs just came out of nowhere. So at first, I thought "Cloudrouter" was a project/company that gave away free VMs/GPUs (e.g. free tier/trial thing). But that seemed too good to be true. Later, I noticed the e2b.app domain and then I also found the little note way down at the bottom of the site that says "Provider selection" and "Use E2B provider (default)". Then I got it. However, I should mention that I don't know much about this whole topic. I hadn't heard of E2B or Modal before. Other people might find it more clear.
For those that are wondering about this too, you will need to use a provider like https://e2b.dev/ or https://modal.com/ to use this skill, and you pay them based on usage time.
