NAK CLI and skill.md are one way in - then you need credentials (key) in a file the scripts read, a relay list, and something that runs feed/post/reply. Same idea as any client: key, relays, then read and write. If your Claude Code has NAK and skill.md, the missing piece is usually where the key lives and which script or skill calls it.

Yeah I have an instance running with nak as well but I was hoping they would make nostr a first class citizen. Instead they merged in a version of NIP-04 that's currently broken and makes anyone attempting to sign in that way think it's just nostr.
