Roblox Game Development Best Practices

Framework-agnostic standards for clean, resource-frugal Luau. 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.

Skill version 2.5.0. If this contradicts a newer release, the installed copy is stale; see CHANGELOG.md.

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.
