# Roblox Luau Engineering

Roblox Studio (October 2026 build) on macOS, driven through the scenario-roblox-expert toolkit.

Expert Luau here means code that stays correct under Deferred events and the task scheduler,
type-checks on both solvers, releases everything it creates, and earns each optimization with a
number measured on this build. Prove behavior in a playtest data model instead of reasoning from
Immediate-era habits.

If a sibling skill named here is missing from your available skills, load it with `skill_get`
(Scenario MCP) or ask the user to install it (https://github.com/scenario-labs/skills#install);
unattended, proceed from tool schemas and flag the gap.
