luau-performance

When to Use

Use this skill when the task is primarily about Luau runtime cost:

• Profiling code to find real hotspots before changing implementation details.
• Reducing allocation churn, GC pressure, or closure creation in repeated paths.
• Choosing faster table construction, lookup, append, and iteration patterns.
• Making code cooperate with Luau fast paths for builtin calls, method calls, and imports.
• Explaining how compiler and runtime optimizations affect hot functions.
• Tuning a confirmed hot path while balancing readability and maintainability.
• Accounting for sandbox or environment behavior only when it changes Luau execution or deoptimizes code.

Do not use this skill when the task is mainly about:

• Teaching general Luau syntax, control flow, tables, or metatables from first principles.
• Designing deep type-system abstractions, analyzer behavior, or advanced type utilities.
• Roblox-specific replication, streaming, rendering, networking, physics, or other engine performance patterns.
