Luau / Roblox Development Skill

Applies to any work inside a Roblox game project written in Luau. Covers correct patterns for strict typing, service architecture, security, persistence, and game-loop design.

1. Mandatory File Header

Every .lua / .luau file must start with:

--!strict

No exceptions. This enables Luau's full type-checker and prevents entire classes of runtime errors. Never omit it, never suppress it with --!nonstrict.
