Hi, this is my project! I was surprised to see it posted here. It's a debugging tool for container images that I host for myself and some friends/coworkers.

Some of its features are intentionally not very discoverable, partially to keep the interface minimal, but mostly because I like to hide them as easter eggs.

I wrote a little more context for how this (and some related tools) came to be at https://dag.dev for the curious.

Happy to answer any questions, of course, but I imagine this is a pretty niche tool.
