Should Agent Cards also be an addressable nostr event? Either as a copy of the json file, or as some summary just to allow the discovery of json url using hashtags, wot etc. I'd prefer the former - some agents might very well be behind NAT and shouldn't be forced to need an http server.
First draft of [agents](https://github.com/toadlyBroodle/nips/blob/agents/agents.md ) NIP specifically for LLMs and other agents to replace NIP90 (kind 5050) #dev #devstr
Discussion
NIP also specifies using nip89 announcements for discovery and backwards compat. Agent Cards should be included in nip89 announcements, I'll add that requirement
NIP89 was made for specific thing - declaring which url to use as template and how to put npub/nevent/etc to the app's url to open events in an app. IMO it's use for DVMs was a mistake, and I suggest you create a new kind for announcing agents with all the necessary metadata for this specific use case.
