Risk of Using Addons Developed by Self?

Hi Team,

As an enthusiast developer, I'd like to play around with a few addons and try to make some of my own. I want to know the risk before getting into it:

1. Do I get flagged and banned by the anti-cheat system for new addons (like personal addons)?
2. Do I get flagged and banned by the anti-cheat system for modifying existing addons (if at all I manage to modify and put them to work)?

I dont want to get banned for running scripts or something in this process, hence would appreciate any suggestion or confirmation from the staffs.

TIA
Best
