Luau Language Mastery (Index)

This skill has been split into three focused skills for better context efficiency. Load the one that matches your task:

Routing

Task	Load
Syntax, tables, control flow, string patterns, math, idioms, scope, closures, sharp edges, JS→Luau porting	`roblox-luau-core`
Type annotations, generics, narrowing, inference, strictness modes, exports, sealed/unsealed tables	`roblox-luau-types`
OOP (metatables, inheritance), async (Promises, pcall, coroutines), module structure, service pattern, Roblox idioms (Instance creation, events, task library)	`roblox-luau-patterns`

Quick Decision

"How do I write this in Luau?" →
```
roblox-luau-core
```
"How should I type this?" →
```
roblox-luau-types
```
"How should I structure this?" →
```
roblox-luau-patterns
```

Key Rules (always apply)

Luau is NOT Lua 5.1. Has: generics,
```
continue
```
,
```
+=
```
, string interpolation (backticks), floor division
```
//
```
Arrays are 1-based.
```
#tbl
```
for length. Generalized iteration:
```
for k, v in tbl do
```
Always use
```
task.wait/spawn/delay
```
(never deprecated
```
wait/spawn/delay
```
)
Instance.new: configure properties THEN set Parent last (replication race)
Services:
```
game:GetService("Name")
```
at top of script, stored in locals
Methods: use
```
:
```
(implicit self) for instance methods,
```
.
```
for constructors/static
Prefer backtick interpolation over
```
..
```
concatenation
Local function order: callees above callers (no hoisting)
Only
```
nil
```
and
```
false
```
are falsy
