Hm, is this to identify an admin pubkey externally via DNS?

This goes a bit outside the scope of Shakespeare the tool, but answering this in the context of an external project - you'd have to tell the application to fetch a TXT record for your domain. As long as the DNS record exists externally for said domain (e.x., traveltelly.com), then the application should be able to fetch it regardless of where it is actually hosted.

You would have to explicitly instruct the agent to "retrieve TXT records from traveltelly.com and extract the key value for nostr-admin-pubkey". This request is a bit more 'complex' for something like Shakespeare/mkstack to handle. It's not completely impossible, but it's certainly outside the scope for what the current tooling is intended to support; or rather, unfortunately, you would be heavily relying on the LLM's direct knowledge/capabilities to make this function. 😔
