roblox-performance · sentinelcore — Claude Code skill: Roblox game optimization

What roblox-performance does

The skill covers Roblox performance topic by topic: StreamingEnabled for large open worlds, object pooling, caching references outside Heartbeat and RenderStepped, swapping wait() for task.wait(), LOD, merging parts into MeshParts, and reading frames in MicroProfiler. It ships with quick-reference tables, Lua examples, and a list of common mistakes.

There is a section on hot-path loops. The agent will tell you not to call FindFirstChild, GetChildren or GetDescendants inside Heartbeat, and to throttle work that does not need to run every frame. A ready ObjectPool module in Lua is included, with a bullet-firing example.

The skill targets the Roblox engine, so it does nothing for projects on other engines. Some fixes live in Studio rather than in code: workspace.StreamingEnabled and the streaming radii are set there. Turn streaming on and parts outside the radius become nil on the client, so you have to guard with if part then — otherwise code that used to work starts throwing errors.
