I have installed Debian testing with i3wm, using SDDM (Simple Desktop Display Manager) to start it. In the i3 workspace, I could find the ssh-agent process already started. However, I still am being prompted to input my key passphrase everytime I do a git push to github (the remote is git@github.com:user/repo.git). See below for the details. Any way to prevent this from happening?

I have already added my id_rsa to my ssh-agent.

$ cat /proc/version 
(Linux version 4.1.0-2-amd64 (debian-kernel@lists.debian.org) (gcc version 4.9.3 (Debian 4.9.3-3) ) #1 SMP Debian 4.1.6-1 (2015-08-23))

$ i3 --version
i3 version 4.10.3 (2015-07-30, branch "4.10.3") © 2009-2014 Michael Stapelberg and contributors

$ ssh -V
OpenSSH_6.9p1 Debian-1, OpenSSL 1.0.2d 9 Jul 2015

$ apt-cache info sddm
Package: sddm
Version: 0.11.0-3

I successfully tested this SSH connection with ssh -v -T git@github.com and it looks fine:

I execute ssh-add in my i3 config file. This way, I am prompted for my passphrase on startup, after which I can use the key without being prompted again.

Don't know what your setup is (how you add your key to the agent or if you use gnome keyring or something), but this may be an option for you, too.
