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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00061 | $0.00300 |
| Opus 5 | $0.00030 | $0.00150 |
| Sonnet 5 | $0.00012 | $0.00060 |
| Haiku 4.5 | $0.00006 | $0.00030 |
Grade A, and why
ux-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 4d 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.
This is a copy
91% identical to design-system — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Port provenance: adapted from the pinned upstream source at
984023ddac0d5e27624f2baacde6105e45de375funder MIT; see the repository parity ledger for the exact path and blob.
Ux Design
This is a full-fidelity Codex port of a large upstream studio workflow. Its
detailed phases, templates, checks, and handoff prompts live in
references/full-workflow.md to keep skill
discovery lightweight.
Required procedure
- Read
references/full-workflow.mdcompletely before executing this skill. - Follow its phases in order and preserve all approval, review, testing, and evidence gates.
- Adapt shell syntax to the detected platform; use PowerShell on Windows and POSIX syntax on macOS/Linux.
- Inherit the active Codex model and permission mode. Never weaken sandbox, approval, provenance, or human creative-control boundaries.
- If a referenced project artifact is absent, report the gap and use the documented fallback instead of inventing completion evidence.
What ships with it
2 files 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.

ux-design is a skill published in the GitHub repository frabcd/codex-ai-game-studio (9 stars, last pushed 7d ago), licensed MIT. It adds 61 tokens to every session and 300 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to design-system, differing in 6 lines, and is treated as a copy.
Other skills, from other repositories
use-widget-asset
Use when consuming a widget slice (panel, button, slider, progress bar, or toggle pair) from a create-asset-sheet pack in a Summer Engine scene. The pack's metadata.sliceMeta carries 9-slice margins, fill rects, and on/off pair links per slice. This skill explains how to wire those into NinePatchRect…
ui-basics
Use when building Summer Engine UI: HUDs, main menus, pause menus, health bars, progress bars, dialogue boxes, or any Control-node tree. Covers anchors, containers (VBox/HBox/Margin), responsive layout, and theme versus inline styling. Trigger on "UI", "HUD", "menu", "health bar", "Control", "anchors"…
game-ui
Design HUDs, menus and diegetic interfaces with controller navigation and readability at TV distance. Use when designing HUDs, inventory menus, or controller-first interfaces.
unity-shaders
Author materials and VFX with Shader Graph, HLSL and URP/HDRP custom passes. Use when authoring URP/HDRP shaders, Shader Graph, or visual effects.
