Roblox Game Development Best Practices

Framework-agnostic standards for writing clean, efficient, lightweight, and resource-frugal Luau code. These rules fit any architecture — they govern how each script is written, not how the project is structured.

Goals, in priority order: correct → secure (server-authoritative) → efficient (CPU/memory/network) → readable → consistent.

Session Invariants (must survive compaction)

A summary that drops these rules silently downgrades every file written afterwards. Two standing obligations:

1. Carry it forward verbatim in any summary, handoff, plan, or task note. It is active instruction, never compressed into "follow the Roblox skill".
2. Re-read this file before acting whenever the card's full text is not visible in your context. Never reconstruct these rules from memory — a half-remembered layout rule looks deliberate and is worse than none.
