roblox-gui · sentinelcore — Claude Code skill: what it does, how to install
Provides reference patterns to build and animate Roblox interfaces, from screen HUDs to in-world 3D panels.
npx skills add sentinelcore/roblox-skills --skill roblox-gui -a claude-codeWhat roblox-gui does
The skill adds validated Luau UI guidelines directly to the agent context. It details container setups for screen-facing ScreenGui objects and floating BillboardGui attachments. It also provides reference rules for UDim2 scaling and AnchorPoint centering, helping prevent interface distortion on different screen resolutions.
Another section covers TweenService transitions and Studio layout bugs. Note that properties like Text cannot be interpolated with TweenService because tweens require numeric or vector formats like Size and Position. The guide also explains how setting ResetOnSpawn to false keeps persistent menus alive between player respawns.
What it helps with
- scale Roblox HUD elements across screen sizes using UDim2
- animate menu panels and progress bars with TweenService
- attach floating status indicators above player avatars
- preserve active interfaces across character respawns
Example prompts for the agent
- Write a LocalScript that slides a shop frame onto the screen using TweenService.
- Create an overhead BillboardGui label for player health with proper stud offsets.
- Center a button on screen using scale values in UDim2 and UIAspectRatioConstraint.

What is the roblox-gui skill?
It supplies coding assistants with verified Luau snippets and layout math for Roblox Studio. This ensures generated GUI scripts handle scaling and container parenting correctly.
Why does the GUI disappear whenever the character respawns?
ScreenGui has ResetOnSpawn enabled by default, prompting the engine to recreate the interface upon death. Set ResetOnSpawn to false to keep menus and HUD elements persistent.
