What is mobiai-react-native?

A guide for React Native, a framework for building mobile apps with JavaScript or TypeScript and native Android and iOS projects. It covers app structure, navigation, state management, building, testing, and debugging.

Use it when building or debugging React Native screens, navigation, state, native modules, and tests.

It helps trace problems across JavaScript or TypeScript code and the native mobile layers where React Native apps can fail.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/ArisGuimera/MobiAI-Core

agentmods

npx agentmods add skills/arisguimera/mobiai-core/mobiai-react-native

Made for: Claude Code.

Or install react-native, the plugin that ships this one along with the rest of its 1 skill.

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	$0.00026	$0.01237
Opus 5.5	$0.00010	$0.00495
Sonnet 5.5	$0.00005	$0.00247
Haiku 4.5	$0.00003	$0.00124

Security

Grade A, and why

mobiai-react-native 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.

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.
