How can you improve your tactical skills in chess?

Best way I can think of is to analyse your losses against more experienced players. Recreate the situations where you lost material/got checkmated, and try to figure out how your opponent visualized the combination that led to you losing.

For beginners, in every situation look for the intention your opponent had while moving his piece and then think about creating a mating net or a threat,pin, eventual fork in minimal move possible without any risk

You posted this in openings. Actually openings and tactics may be more closely related than you think.

It's known that very advanced chessplayers spend the vast majority of their time studying openings - but why, do they just know all the tactics and don't need to train them? Of course not, it's that they go so deep into openings and see all the typically recurring tactics for their openings including all the way to a decisive attack - and sometimes even an endgame. While specialized tactics training can be good for lower rated players, noticing them coming up as part of your openings can be a very economical way of doing it over time. This is particularly the case when you think of how the main openings will always be there for revision, while tactics you see in a book might gradually fall out of your mind completely.
