Does the expression "to keep on one's toes" basically mean "to walk on eggshells" ?

I saw it used in sentences along the lines of these:

I need to keep on my toes
In the end, no major harm was done, but I have to keep on my toes with her

If I'm wrong about its meaning, could you provide your explanation, please?

Thanks !
You have to be very alert and ready to act quickly.

Someone playing baseball in the outfield better stay on their toes when a batter know for long hits comes to bat. The sense is alert and ready to act.

Walk on eggshells is another metaphor - it means someone may get angry very easily, or there is a situation that is barely hanging in balance and you can mess it up by acting to hastily. The sense is being very careful to not upset anything or anyone.
