I don't understand and I'm curious, why a dead on arrival open source tool needs a separate domain?

  Domain Name: prompt-caching.ai

It's more likely the other way around, the .ai domain with a fairly generic and maybe future-proof name needed a quick vibecoded project to not be empty when it launches.

Is it perhaps because this is for claude code but there's other tools that use anthropics api like custom agents? (some i prefer to use than claude code - e.g sketch.dev what is now called shelley at exe.dev) perhaps?

No, because this doesn’t actually “fix” any existing code. It’s only useful for helping an LLM to modify your code to adjust the caching parameters in the right place, but it doesn’t have the correct API for that.
