How to update symbology in a script tool without updating from another layer?

I am making a script tool that will result in a point feature class, and I would like to update the symbology on that feature class in the current map so that the results are displayed the same for each user. I have a field with unique text values that I want to use for the symbology, and I'm trying to find a way to say "Value A is size 10 red point", "Value B is size 12 blue point", etc., without using a reference layer. Because this tool will be shared, it strikes me as cumbersome to have an additional layer that I have to share with the tool to get the same symbology.


I've been digging around forums, etc. online for a while and can't find a solution in which the symbology is coded within the script tool. Any basic ideas for workflow or places I can go for answers is greatly appreciated!
