When I'm running Gnome, ssh-agent will run ssh-add upon slogin/ssh if the identity is not loaded. I want to mimic this behavior on remote shells, but everything I find suggests to run ssh-add upon login. I only want to run ssh-add if I subsequently run slogin/ssh on the remote shell, not every time I login.

I worked out a solution for this via the bash shell.
Add to .bashrc:
check-ssh-add()
if [ "$DESKTOP_SESSION" == "" ]; then
if [[ `ssh-add -l` != *id_?sa* ]]; then
ssh-add -t 5h ## 5 hour ssh-agent expiration
fi
fi
slogin()
check-ssh-add
/usr/bin/slogin $@
ssh()
check-ssh-add
/usr/bin/ssh $@
scp()
check-ssh-add
/usr/bin/scp $@
sftp()
check-ssh-add

There's actually an even simpler way. ssh-add -l returns true (0) if there are keys and false (1) otherwise, so your first function can be replaced with this:
check-ssh-add()
if ! ssh-add -l >/dev/null; then
ssh-add -t 5h
fi
