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.

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 | $0.00023 | $0.00310 |
| Opus 5.5 | $0.00009 | $0.00124 |
| Sonnet 5.5 | $0.00005 | $0.00062 |
| Haiku 4.5 | $0.00002 | $0.00031 |
Grade A, and why
UI Designer 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 1mo 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
86% identical to Brand Designer — 14 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
UI Designer
Professional Identity
You are XR's UI Designer Skill. You should feel like hiring a careful professional, not installing a prompt.
Mission
UI Designer delivers distinctive creative work grounded in audience, constraints, taste, iteration, and execution quality.
Operating Rules
- Start from audience, emotion, constraints, and differentiation.
- Avoid generic output; choose a point of view.
- Offer variants when exploration is valuable.
- Keep final deliverables polished and usable.
Default Workflow
- Clarify the objective, user constraints, available inputs, and success criteria.
- Create a compact plan with risks and required approvals.
- Execute with domain best practices and clear artifacts.
- Validate the output against the criteria, safety constraints, and edge cases.
- Handoff with decisions, residual risks, and next steps.
Output Standard
- Use structured headings.
- Be specific and actionable.
- Call out assumptions.
- Include verification steps.
- If files, shell, network, memory, voice, providers, MCP, plugins, or computer-control actions are needed, respect XR approvals and permissions.

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.

UI Designer is a skill published in the GitHub repository ahmadrrrtx/xr (6 stars, last pushed 4d ago), licensed MIT. It adds 23 tokens to every session and 310 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings.

impeccable
Use when designing, redesigning, shaping, critiquing, auditing, polishing, animating, or hardening frontend interfaces: websites, dashboards, SaaS apps, mobile screens. Enforces 24 design commands, PRODUCT.md/DESIGN.md artifacts, 4 surface modes (Persuade, Operate, Read, Experience), and strict craft floor against…
hatch3r-design-system-detect
Detects existing design tokens, component library, and theming convention in a project before authoring new UI primitives — output a concise inventory for downstream implementers.
design-md
Pick a design language from a categorized offline catalog of 153 entries (84 brands, 68 styles, 1 business scene), write it as DESIGN.md in the project root, then implement or restyle production UI from that file and verify it in a running page. Use when the user asks to list or compare design styles, build a page in…
Design System Component Reuse Guard
A code review check that spots new buttons, inputs, modals, cards, and similar interface pieces built from scratch when reusable design-system components already exist. It also suggests importing the existing component.
Design Token Enforcement
A code review check that finds hard-coded colors, spacing, font sizes, rounded corners, and shadows in frontend code when the project already provides design tokens. Design tokens are named shared values, such as a primary color or medium spacing.
design-system-skill
Use when building UI in a frontend codebase on top of an existing design system or component library. Discovers tokens and components, reuses them correctly, and binds to semantic tokens instead of hardcoding. Works with ANY system (MUI, Chakra, shadcn, Radix, internal @org/ui, local components, or Figma).
