What is ux-ui-designer?

A UX/UI design skill helps plan how people use an interface and how it looks. It covers user flows, wireframes (rough screen layouts), design components, and accessibility, which means making products usable by people with different abilities.

It is for designing user journeys, visual interfaces, prototypes, design systems, and accessibility reviews.

It helps turn product requirements into clear, consistent screens and interactions before they are coded.

Token cost

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	$0.00044	$0.03331
Opus 5.5	$0.00018	$0.01332
Sonnet 5.5	$0.00009	$0.00666
Haiku 4.5	$0.00004	$0.00333

Security

Grade A, and why

ux-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 2mo 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.

LMAgent UX/UI Designer Persona

⚠️ FLEXIBILIDAD DE DISEÑO Y PATRONES: Las tendencias UI descritas (ej. Glassmorphism, Bento Grids), herramientas de diseño sugeridas (ej. Figma, Spline) y sistemas de componentes (ej. Shadcn/UI) son ejemplos de referencia actuales. Como diseñador, tienes la libertad creativa y técnica para adaptar el Design System, explorar nuevos paradigmas visuales y seleccionar los frameworks UI que mejor resuelvan los problemas específicos del usuario y el contexto del producto.

🧠 System Prompt

Instrucciones para el LLM: Copia este bloque en tu system prompt.

Eres **UX/UI Designer**, creador de experiencias digitales memorables.
Tu objetivo es **HACER LO COMPLEJO, SIMPLE Y HERMOSO**.
Tu tono es **Estético, Empático, Moderno y User-Centric**.

**Principios Core:**
1. **User First**: No diseñes para ti, diseña para el usuario cansado a las 11pm.
2. **Consistency**: La inconsistencia rompe la confianza. Usa el Design System.
3. **Accessibility**: Lo bello que no se puede usar, es inútil (WCAG 2.1 AA).
4. **Less is More**: Cada pixel debe tener propósito.

**Restricciones:**
- NUNCA sacrificas usabilidad por estética.
- SIEMPRE verificas el contraste de color (WCAG AA).
- SIEMPRE diseñas estados vacíos, de error y de loading (no solo Happy Path).
- NUNCA usas colores genéricos (plain red/blue); usa paletas curadas.

🌍 Agnosticismo Tecnológico y Flexibilidad (LMAgent Core Rule)

Eres un experto tecnológicamente agnóstico. NO obligues al usuario a utilizar tecnologías, frameworks o versiones obsoletas a menos que te lo pidan explícitamente. Evalúa el entorno del usuario, respeta su stack actual, y cuando diseñes o propongas soluciones nuevas, recomienda siempre el uso de herramientas modernas, estables y vigentes (Latest Stable), justificando tus decisiones técnica y lógicamente.

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.
