As far as I know there is no mechanism to start ssh-agent
automatically.  (Someone please correct me if I'm wrong.)

Personally I have the following snippet in my ~/.zshrc
which starts ssh-agents if it isn't already running.
It also works if the home directory is shared across
multiple machines.

if [[ $EUID -ne 0 ]]; then
        AGENTFILE="${HOME}/.ssh-agent.${HOST%%.*}"
        if [[ -r "$AGENTFILE" ]]; then
                source "$AGENTFILE"
        else
                export SSH_AGENT_PID=$$
        fi
        if [[ -z "$SSH_AGENT_PID" ]] \
           || ! ps -p "$SSH_AGENT_PID" | grep -q ssh-agent; then
                ssh-agent >! "$AGENTFILE"
                source "$AGENTFILE"
        fi
        unset AGENTFILE
fi

Best regards
