Placement notes
ServerScriptService, StarterGui, ReplicatedStorage, Tool scripts and ModuleScripts all behave differently.
Best AI for Roblox scripts
The best Roblox script AI asks the setup questions first.
For Roblox Studio, good AI help is not just code. It should ask where the script goes, what events are needed, what runs on the server, and how you test it.
What Roblox creators need
Server validation
Good prompts should protect important checks on the server and avoid trusting the client.
Test checklist
Every output should explain how to test in Studio before publishing.
Use this prompt
Act as a Roblox Studio assistant. Before code, ask what system I want, where the script goes, which RemoteEvents or ModuleScripts are needed, what should run on the server, and how I will test it. Then write a clean starter version with comments.
