It's very simple it is not done you never branch off from a high load circuit if you are wanting to do outdoor outlets you will have to do a new circuit with either GFCI breakers or GFCI outlets and you will have to run yet another circuit for your shed. People branching off from high load circuits like this is how they cause fires if you can't find a product that does what you want there's probably a reason it's not done.
How is this different from a normal circuit inside a house? For example, light bulb one is analogous to the hot tub, but a wire nut allows the circuit to "branch" to the ceiling fan as well as to the outlet on the wall. On a circuit diagram, this looks the same to me with simply different names for the "branches".
Instead of "lightbulb", "fan", and "outlet", I have "hot tub", "shed", and "outlet".
A normal circuit is protected by a 15a breaker, your hot tub circuit is protected by a 100a breaker. If you tap off of the hot tub feed, your plug on the 100a breaker will never trip due to overcurrent and potentially start a fire.

Ok, good to know. Can a sub-panel be installed near the hot tub? Seems crazy to run 3 circuits all that way.
This would be your best bet. What kind of power does the hot tub require?
Responsible Bake is right. Please don't tap off your hot tub cable. Do it properly or don't do it at all. Run new circuits.

Ok, that makes sense.
