Hey, Thank you for working on this, Can you also add a workflow for this check on very push and pull req?
Similar implementation can be found here in valkey: https://github.com/valkey-io/valkey/blob/unstable/.github/workflows/clang-format.yml:

Do we also want to use this: https://github.com/valkey-io/valkey-json/blob/unstable/src/json/CPPLINT.cfg?

Yes, I will finish it later.

I was concerned that you might need the cpplint.cfg file, so I kept it. If you don't need it, I'll remove it later.

Okay will wait and review again when wfs are added.
