You're not alone. Even worse when it is a product page. Just how often I see some product or project and are unable to actually determine what the thing does or why I would want to use it or even HOW to use it.
I can give GitHub projects a pass when someone else links them, but the poster is the author so no pass. This is "Show HN". Please __show__. I do like to try out new projects and tools, but where's the hook?
Also, do not underestimate the importance of documentation. Hell, I document predominantly for myself. I know I'm not alone in forgetting how things work if I haven't touched a project in awhile (which can even be going to lunch on bad days). This is also critical for any users. Encourage them to add docs, make it easy, and when addressing issues recognize that just because it is in the docs does not mean it's interpretable from user context.
If you want to demonstrate a CLI or TUI tool, a common helper is asciinema[0]. You can record your terminal and they'll host the output for you. You'll frequently see these on GitHub and even a 10 second video that is clunky/slow with key presses (or way too fast) is better than nothing. UIs matter and aren't as simple/obvious as many think.
Also, drop a license file in there. Not just a line in your README. Come on, GitHub even hands these files to you so it is the same work to write in your README as it is to drop that file in (though you should always mod those licenses headers to be about you and your project). Without the license file, your license is ambiguous and may not actually protect your project as intended. The full text needs to exist.
