## What it does

The skill walks the agent through a fixed order. First inspect existing `ScreenGui`s, fonts, colors and reusable components in Explorer, then decide ownership and lifecycle. `StarterGui` is the authored template and Roblox clones it into each player's `PlayerGui`, so `ResetOnSpawn = false` decides whether a screen survives respawn. Stale references to a destroyed clone are a bug.

Next comes a readable hierarchy of editable Instances and small behavior modules, plus responsive structure built from `UDim2` scale, bounded offsets, `UIPadding`, `UIGridLayout` and `AutomaticCanvasSize`. Interactive elements stay inside `CoreUISafeInsets` so touch controls do not cover them. State renders from a small view state, buttons use `Activated`, and gamepad navigation gets an explicit entry point through `GuiService.SelectedObject`.

Verification runs in Device Simulator and Controller Emulator: desktop, narrow portrait, mobile landscape, tablet, console, then a respawn. The skill targets Roblox engine APIs and pairs with `game-ui-ux` for engine-neutral UX; action mapping belongs to `input-systems` and server trust to `roblox-networking`. Worth installing if your UI is one giant `LocalScript` that nobody wants to touch.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill roblox-ui -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/roblox-ui/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/roblox-ui/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill roblox-ui -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/roblox-ui/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill roblox-ui -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/roblox-ui/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install gamedev-skills/awesome-gamedev-agent-skills roblox-ui
```

2. **Manually: put the files in place**
- File: `.github/skills/roblox-ui/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill roblox-ui -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/gamedev-skills/awesome-gamedev-agent-skills --path skills/other-engines/roblox-ui
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/roblox-ui/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add gamedev-skills/awesome-gamedev-agent-skills --skill roblox-ui -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- build a HUD that holds up on a narrow phone screen
- fix UI that resets after respawn
- replace pixel layouts with responsive UDim2 structure
- add gamepad navigation with an explicit focus path
- split one giant LocalScript into components and modules

## Example prompts
- Build an inventory ScreenGui with UIGridLayout and AutomaticCanvasSize that works in portrait and landscape
- Add gamepad navigation: focus the first button on open, clear SelectedObject on close
- Check this HUD in Device Simulator at narrow portrait and in Controller Emulator, note where text clips

  Build production Roblox interfaces with ScreenGui/PlayerGui lifecycle, responsive UDim2

  settings, ability bars, ScrollingFrames, AutomaticSize, GuiService, gamepad focus, touch UI, or

# Roblox UI

Implement deliberate, editable Roblox UI that preserves the experience's visual language and
works across supported devices. Targets Roblox's rolling platform APIs. Pair with `game-ui-ux`
for engine-neutral information architecture and UX; this skill owns Roblox Instances and APIs.

## When to use

- Use for authored `ScreenGui` interfaces, Roblox layout/constraint APIs, UI lifecycle, input,
  focus, animation, performance, or responsive/device fixes.
- Use to replace brittle pixel layouts, runtime-created Instance tangles, mouse-only menus, or
  generic generated styling with a maintainable hierarchy.

**When not to use:** general UX flow and accessibility principles belong to `game-ui-ux`; raw
gameplay action mapping belongs to `input-systems`; server trust belongs to `roblox-networking`.

## Workflow

1. **Inspect before designing.** In Explorer, inventory existing `ScreenGui`s, UI modules,
   fonts, colors, icon family, spacing, corners, strokes, animation timing, naming, and reusable
   components, including any `StyleSheet`/`StyleLink` styling, tokens and themes. Capture
   representative screenshots at two viewports. Extend that language.
2. **Define ownership and lifecycle.** `StarterGui` is the authored template; Roblox clones it
   into each player's `PlayerGui`. Decide whether each `ScreenGui` should persist across respawn
   with `ResetOnSpawn = false`; never keep stale references to a destroyed clone.
3. **Author a readable hierarchy.** Prefer meaningful editable Instances and small behavior
   modules. A normal screen should be understandable in Explorer; procedural generation is for
   genuinely data-driven repetition, not the whole shell.
