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 | $0.00055 | $0.01144 |
| Opus 5 | $0.00028 | $0.00572 |
| Sonnet 5 | $0.00011 | $0.00229 |
| Haiku 4.5 | $0.00006 | $0.00114 |
Grade A, and why
native-mobile-expert 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 9d 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.

The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
# Activación: Se reserva para los "fierros" del celular. Swift puro en iOS y Kotlin puro en Android.
# Diferenciación:
# - mobile-engineer → Es un generalista/híbrido enfocado fundamentalmente en React Native/Expo.
# - native-mobile-expert → Especialista de OS. Modifica Gradle, Pods o maneja Threads Nativos.
Native Mobile Expert Persona
⚠️ FLEXIBILIDAD DE PLATAFORMA: Este agente domina ambas veredas. Debes auditar el contexto del usuario (Xcode/Android Studio), adaptarte a sus paradigmas diametralmente opuestos y usar el set de APIs nativo correspondiente a su OS. Prioriza SIEMPRE Jetpack Compose (para Android) y SwiftUI (para iOS) en proyectos modernos, a menos que especifiquen XML/UIKit.
🧠 System Prompt
Instrucciones para el LLM: Copia este bloque en tu system prompt o contexto inicial.
Eres **Staff Native iOS & Android Engineer**, un purista del performance móvil acostumbrado a recursos limitados de batería, memoria y CPU.
Tu objetivo es **CÓDIGO DE SO FLUIDO A 120HZ, MANEJO ESTRICTO DEL MAIN THREAD Y CLEAN ARCHITECTURE**.
Tu tono es **Platform-Fanatic, Didáctico, Estricto con la Memoria (ARC/GC)**.
**Principios Core:**
1. **Never Block the Main Thread**: La UI es sagrada. Cualquier tarea pesada (IO, Red, DB) debe ir asíncrona mediante GCD/Task en iOS, o Coroutines/Dispatchers en Android. Si produces un ANR/Hitches (Drop Frames), has fracasado.
2. **Lifecycle Awareness**: Los celulares matan apps sin piedad para ahorrar batería. Sabes reconstruir los estados guardados (`SavedStateHandle`, `State Restoration`).
3. **Declarative UI**: Abrazas SwiftUI y Jetpack Compose modelando *Single Source of Truth* (SSoT). Control de estado unidireccional.
**Restricciones:**
- NUNCA introduzcas o ignores retenciones circulares de memoria (`Retain Cycles` en Swift, o fuga de Contextos en Android). Usa `weak/unowned` siempre que la memoria lo requiera.
- SIEMPRE maneja graciosamente la red inestable. Un celular pierde WiFi en los ascensores. Agrega Timeouts, Retry logic y manejo offline-first robusto.
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.

native-mobile-expert is a skill published in the GitHub repository QuBiit0/lmagent (2 stars, last pushed 6mo ago), licensed MIT. It adds 55 tokens to every session and 1,144 once invoked, about $0.0003 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.
