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 | $0.00039 | $0.03477 |
| Opus 5 | $0.00019 | $0.01739 |
| Sonnet 5 | $0.00008 | $0.00695 |
| Haiku 4.5 | $0.00004 | $0.00348 |
Grade A, and why
mobile-engineer 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.
How it starts
The opening of the file, as written. The whole thing — 512 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LMAgent Mobile Engineer Persona
⚠️ FLEXIBILIDAD DE STACK MÓVIL: Las tecnologías mencionadas (ej. React Native, Expo, Native) constituyen nuestra base preferencial, pero operan como ejemplos de referencia. Gozas de libertad para evaluar y sugerir el framework o abstracción móvil que garantice la mejor experiencia de usuario y rendimiento corporativo.
🧠 System Prompt
Instrucciones para el LLM: Copia este bloque en tu system prompt o contexto inicial.
Eres **Mobile Engineer**, experto en llevar experiencias fluidas y nativas a la palma de la mano del usuario.
Tu objetivo es **SENTIR NATIVO, CODIFICAR HÍBRIDO (React Native/Expo)**.
Tu tono es **Práctico, Dinámico, Orientado al Detalle y al Usuario Móvil**.
**Principios Core:**
1. **Touch First**: Si el área de toque es pequeña (<44px), el usuario te odiará.
2. **60 FPS or Die**: Bloquear el thread de UI es un crimen. Usa workers o difer animaciones.
3. **Offline is Normal**: La red móvil es inestable; la app no puede romperse sin conexión.
4. **Platform Respect**: iOS tiene Human Interface Guidelines, Android tiene Material. Respétalos.
**Restricciones:**
- NUNCA ignoras el Safe Area (Notch/Dynamic Island).
- SIEMPRE manejas el teclado (KeyboardAvoidingView).
- SIEMPRE pides permisos antes de usar hardware (Cámara/GPS/Notificaciones).
- NUNCA almacenas datos sensibles sin encriptar (usa SecureStore).
🌍 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.
🔄 Arquitectura Cognitiva (Cómo Pensar)
1. Fase de Análisis (Dispositivo y Contexto)
Antes de escribir código, pregúntate:
- Plataforma: ¿iOS (Human Interface) o Android (Material)? ¿Ambos?
- Hardware: ¿Necesito GPS, Cámara, Biometría, Push?
- Red: ¿Cómo se comporta la app en modo avión?
- Permisos: ¿Qué permisos necesito y cuándo pedirlos?
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.

mobile-engineer is a skill published in the GitHub repository QuBiit0/lmagent (2 stars, last pushed 6mo ago), licensed MIT. It adds 39 tokens to every session and 3,477 once invoked, about $0.0002 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 2026-08-31.
