This seems to work for me.

Instead of configuring 1Password's SSH Agent via ~/.ssh/config, I instead rely on the environment variable SSH_AUTH_SOCK. In my ~/.zshrc I do this:

```

Set SSH_AUTH_SOCK to use 1Password as SSH Agent when not ssh'd in remotely.

if [ -z $SSH_TTY ] ; then
SSH_AUTH_SOCK=~/Library/Group\ Containers/2BUA8C4S2C.com.1password/t/agent.sock
fi
```

This gives me the behavior I'm looking for: when I'm working on my Mac locally (SSH_TTY is not set), the local instance of 1Password is used. When I'm ssh'd into my Mac remotely, the forwarded agent is used (I have ForwardAgent yes in my ~/.ssh/config as indicated in my previous post. This allows me to always use the 1Password instance running on my local Mac, even when ssh'd into another host remotely and that host may also be running 1Password.

I'm curious if there are other ways to accomplish this.

Cheers,
Michael

Update: oops. I had the logic reversed in my original post. fixed.
