Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How are most EKS clusters deployed?
If you want somewhat viable setup - I'd go for terraform-aws-modules (Anton did an awesome job), and aws-ia blueprints, especially those multi-tenant ones.

whats your development process for github actions and how are you testing them?
Personally I use pre-commit with some of these hooks in addition to some default hooks. It's basically a localised CI pipeline, and also means every commit has passed checks so keeps your commit history neat. Way faster to develop infrastructure code and fix issues than having to keep pushing to the remote repo and waiting for an Action to run.

Can you validate ".tf" files via a script ?
Take a look on pre-commit scripts for terraform: https://github.com/antonbabenko/pre-commit-terraform. Of course, you can run it before git operations, for example:
