What is react-native-expert?

A specialist guide for building mobile apps with React Native, a framework for creating iPhone and Android apps with JavaScript or TypeScript.

Use it to plan components and app architecture, diagnose issues, improve performance, connect native iOS or Android features, and manage platform differences.

It helps when you need advice on app structure, navigation, data handling, speed, device-specific code, or React Native problems.

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	$0.00226	$0.01811
Opus 5.5	$0.00090	$0.00724
Sonnet 5.5	$0.00045	$0.00362
Haiku 4.5	$0.00023	$0.00181

Security

Grade A, and why

react-native-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 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.

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.
