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 | $0.00000 | $0.00371 |
| Opus 5 | $0.00000 | $0.00186 |
| Sonnet 5 | $0.00000 | $0.00074 |
| Haiku 4.5 | $0.00000 | $0.00037 |
Grade A, and why
ui-master-craftsman 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 7d 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.
What it actually says
name: ui-master-craftsman description: Skill de maestría en diseño de interfaces para terminal (Lanterna) y 3D (LibGDX). Úsala para asegurar consistencia visual, rendimiento de renderizado y una UX moderna y pulida.
UI Master Craftsman
Esta skill proporciona conocimiento experto sobre:
- Terminal UI (Lanterna): Patrones de diseño para interfaces de consola, gestión de eventos de teclado/ratón y optimización del buffer de pantalla.
- 3D UI/Rendering (LibGDX): Implementación de HUDs, diseño de cámaras, uso eficiente de fuentes y shaders para una estética "procedural" moderna.
- Coherencia Visual: Directrices para mantener la identidad del proyecto tanto en 2D como en 3D.
Cómo utilizar esta Skill
1. Análisis de UX/UI
Cuando diseñes o refactorices una pantalla, consulta UI_GUIDELINES.md para asegurar que el diseño respeta la jerarquía visual y la usabilidad.
2. Implementación Técnica
Usa TECHNICAL_BEST_PRACTICES.md para elegir la mejor implementación (Lanterna vs. LibGDX) y asegurar que el código sea eficiente y desacoplado (MVP).
3. Checklist de Calidad Visual
Antes de finalizar cualquier tarea, Jorge debe responder:
- ¿Es la interfaz intuitiva para el usuario final?
- ¿Cumple con los estándares de rendimiento (evitando redibujos innecesarios en consola / usando frustum culling en 3D)?
- ¿Se siente "moderna y viva" (espaciado, tipografía, feedback interactivo)?
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.

ui-master-craftsman is a skill published in the GitHub repository antoniovazquezaraujo/LeTrain (14 stars, last pushed 2d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 371 tokens. 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 2026-09-04.
