NixOS SSH-Agent Connection Refused

Working on switching to NixOS so this is a new install hasn't worked yet (have had SSH-Agent work on previous Ubuntu install without issue).

When attempting to SSH, I see get_agent_identities: ssh_get_authentication_socket: Connection refused. Polkit is setup (I'm assuming) as I can unlock 1Password with my system password.

I do notice that if I set export SSH_AUTH_SOCK=~/.1password/agent.sock and run ssh-add -l, my keys are there, but trying to SSH even with the environment variable set, I still get the connection refused.

I am confused on what the deal is with the following lines:

debug1: identity file /home/stark/.ssh/id_rsa type -1
debug1: identity file /home/stark/.ssh/id_rsa-cert type -1
debug1: identity file /home/stark/.ssh/id_ecdsa type -1
debug1: identity file /home/stark/.ssh/id_ecdsa-cert type -1
debug1: identity file /home/stark/.ssh/id_ecdsa_sk type -1
debug1: identity file /home/stark/.ssh/id_ecdsa_sk-cert type -1
debug1: identity file /home/stark/.ssh/id_ed25519 type -1
debug1: identity file /home/stark/.ssh/id_ed25519-cert type -1
debug1: identity file /home/stark/.ssh/id_ed25519_sk type -1
debug1: identity file /home/stark/.ssh/id_ed25519_sk-cert type -1
debug1: identity file /home/stark/.ssh/id_xmss type -1
debug1: identity file /home/stark/.ssh/id_xmss-cert type -1
debug1: identity file /home/stark/.ssh/id_dsa type -1
debug1: identity file /home/stark/.ssh/id_dsa-cert type -1

As I do not have those in my .ssh folder, not sure if this is a random NixOS thing or I'm just not very observant or if this is just a red herring and means absolutely nothing.

```
→ ls ~/.ssh
