I've been trying to switch to using the 1P SSH Agent full-time and while it's working great for my regular servers' SSH and commit signing, the SSH Git(Hub) connections are giving me issues when git is ran from/by a Node.js script when using a key in a repo that uses https://docs.github.com/en/enterprise-cloud@latest/authentication/authenticating-with-saml-single-sign-on/authorizing-an-ssh-key-for-use-with-saml-single-sign-on

The problem

Considering the following SSH config:
```
Host *
IdentityAgent "~/Library/Group Containers/2BUA8C4S2C.com.1password/t/agent.sock"

Host github.com
IdentityFile ~/.ssh/keys/github.pub
```

Where github.pub is the public key of an SSH key from my vault.

Using the git CLI in a regular context (fish shell 3.5.1 in iTerm2 3.5.0beta9) works fine and prompts the Agent like expected:

However, running inside the same repo but using the git command inside a script causes an error. Considering the following script:
```
import { exec } from "child_process";

(async () => {
exec(
'GIT_SSH_COMMAND="ssh -v" git pull',
{ cwd: process.cwd() },
console.log
);
})();
```

yields the following error when ran


debug1: SSH2_MSG_EXT_INFO received
debug1: SSH2_MSG_SERVICE_ACCEPT received
debug1: Authentications that can continue: publickey
debug1: Next authentication method: publickey
debug1: Offering public key: /Users/damien/.ssh/keys/github.pub ED25519 SHA256:4qAKLnbwSPfhZggpEDaJRo5SQe982Do8A6vOS6jAcEM explicit agent

debug1: No more authentication methods to try.

fatal: Could not read from remote repository.


With those interesting warnings in 1Password's log file when the script runs

My current (hacky) workaround

After battling for two days with my SSH config file I figured out a workaround. It's not pretty but it works fine:

• Remove the Git bit from my main ssh config
• Create another config file in .ssh, named config-git
• Put the Git bit from before in that newly created file
• Set the GIT_SSH_COMMAND value to ssh -F ~/.ssh/config-git
• Export the private key of my Git SSH key
• Run ssh-add --apple-use-keychain <path_to_key_file>
• Now both a regular git pull and the script above works.
