Reason for my rejection of GitHub action?

I am a newbie in GitHub actions.
Recently I created a GitHub actions as I had participated in the GitHub actions hackathon.
But today i found out that my GitHub action was rejected! Stating “Not a suitable GitHub actions”

This is my GitHub action-

Its an awesome GitHub action were you can conduct a coding competetion like hackerrank/code-chef
With functionalities like custom Input/Output test cases and Individual code reviews via CI on GitHub.

My question is What did I do wrong?
Why was my action rejected?
