Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00025 | $0.00634 |
| Opus 5 | $0.00013 | $0.00317 |
| Sonnet 5 | $0.00005 | $0.00127 |
| Haiku 4.5 | $0.00003 | $0.00063 |
Grade A, and why
roblox-ui-design scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Roblox UI Visual Design
When to Load
Load for UI design or review. Existing style and art direction take priority. Otherwise derive a restrained system from the game fantasy and screen job. Load roblox-gui for mechanics.
Quick Reference
Establish the visual system
- Inspect existing surfaces, type roles, borders, depth, icons, spacing, and action colors. Reuse consistent tokens.
- If no style exists, name the screen job and game fantasy before choosing colors, fonts, or decoration.
- Define a small token set: background, surface, raised surface, text, muted text, accent, danger, border, radius, spacing, and type roles.
- Choose density from the task and device. A HUD, inventory grid, settings list, and purchase prompt should not share one topology.
- Use simulator styling only when the game or art direction calls for it. The full reference keeps an optional recipe.
Core principles
- Topology: choose single-focus, collection, compare, HUD, list, or another justified shape. Do not force every task into a centered modal.
- Hierarchy: one object, state, or action gets the strongest contrast and scale. Quiet secondary content.
- Flow: each repeated flow has one owner:
UIListLayout,UIGridLayout, or shared-column math. - Density: size the complete panel around useful content. Do not stretch shells or add metadata to occupy space.
- Bounds: sum widths, gaps, padding, borders, and minimums. Keep strokes and backings inside parents.
- Alignment: use shared layouts, fixed icon slots, and matching anchors.
- State: active, available, locked, completed, selected, and disabled states need more than color.
- Input: design hover only where it exists. Touch, gamepad focus, keyboard, and reduced motion need equivalent feedback.
- Verification: inspect representative target viewports for clipping, overflow, dead space, type, hierarchy, and focus order.
Neutral fallback
Use one restrained surface and border language, one display role, one body role, and one accent. Let game content, artwork, and action importance create identity. Prefer readable contrast and clear grouping over thick outlines, ornamental depth, or genre assumptions.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

roblox-ui-design is a skill published in the GitHub repository TabooHarmony/roblox-brain (42 stars, last pushed 5d ago), licensed MIT. It adds 25 tokens to every session and 634 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
