Do you have some GitHub samples to achieve the things you talk about? I had no clue my contacts are accessible usingbmy termux

You need a tutorial, not code example. As there are a bunch of pre compiled command line tools, all of which come from a single package installation, that you can use to send SMS, access address book and do other things from the command line.

Install from F-Droid to get access to all of those.
