I don't know for sure but, as others have pointed out, yesterday's submission was the third time you'd posted it to Show HN. People have a low tolerance for dupe posts, especially if they're perceived as excessive self-promotion.
Also, your work might be seen as vibecoded and therefore "ai slop". I dont know if it is, but all it takes is a perception.
Finally, your work might be seen as a commercial threat by some people here - causing them to flag it.
> how i can share my work with HN community
Write a technical article about some aspect of what you've done. Talk about the challenges and how you solved them. Include a link to the repo. Put it in an external site (even github) and submit a link. If its interesting then people will notice.
After that, I asked an HN Mod what the problem was, and they thought my posts were created by GenAI, and because of that, they were flagged. And he gave me the advice that I don't use GenAI at all for HN, not even to polish my crappy text.
Hope this was helpful, wish you a good Day

I think you need to practice your "elevator pitch" technique before you submit here again.
