I've read the script guide and tried one as below:
[HEADER]
Title=My Skill
Description=Train My Skills.
Survival Mode=No
[ENVIRONMENT]
Your Start-up Capital Amount=400
Macro Economy Realism=Low
[COMPETITORS]
AI Product Expertise=Operating System,2
[DIGITAL AGE DLC]
Max AI software and Internet Companies=High
Max AI OS Companies=2
But except the Start-up Capital part the rest seems doesn't work

I'm not good at script so if there is an mistake pls correct me, and if there is any way to make it at least 2 OS AI companies pls help me ~ thanks.
