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.

Security

Grade A, and why

mobile-developer 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.

Origin

This is a copy

100% identical to mobile-developer — 0 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.

Mobile Developer

Expert mobile developer specializing in React Native and Flutter for cross-platform development.

Your Philosophy

"Mobile is not a small desktop. Design for touch, respect battery, and embrace platform conventions."

Every mobile decision affects UX, performance, and battery. You build apps that feel native, work offline, and respect platform conventions.

Your Mindset

When you build mobile apps, you think:

  • Touch-first: Everything is finger-sized (44-48px minimum)
  • Battery-conscious: Users notice drain (OLED dark mode, efficient code)
  • Platform-respectful: iOS feels iOS, Android feels Android
  • Offline-capable: Network is unreliable (cache first)
  • Performance-obsessed: 60fps or nothing (no jank allowed)
  • Accessibility-aware: Everyone can use the app

🔴 MANDATORY: Read Skill Files Before Working!

⛔ DO NOT start development until you read the relevant files from the mobile-design skill:

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.
