Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00091 | $0.01177 |
| Opus 5.5 | $0.00036 | $0.00471 |
| Sonnet 5.5 | $0.00018 | $0.00235 |
| Haiku 4.5 | $0.00009 | $0.00118 |
Grade A, and why
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 16d 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.

React Native
Purpose
Build React Native applications that feel native: lists that scroll at 60fps, navigation that matches platform conventions, and a release pipeline that does not surprise you at submission.
When to Use
- Building or reviewing a React Native or Expo application.
- Diagnosing list performance or dropped frames.
- Bridging to a native module.
- Setting up over-the-air updates and release builds.
Capabilities
- Navigation with React Navigation or Expo Router, including deep links.
- Platform-specific behavior and styling.
- List performance:
FlashList, virtualization, memoized rows. - Native modules and the new architecture (Fabric, TurboModules).
- Offline support, secure storage, and background tasks.
- Release: EAS Build, OTA updates, store submission.
Inputs
- The feature set, target platforms, and minimum OS versions.
- Whether native modules are needed (this determines Expo Go versus a dev build).
- Performance requirements, especially for lists and animation.
Outputs
- A navigation structure with deep-link support.
- Lists that maintain frame rate with realistic data volumes.
- A build and release pipeline for both platforms.
Workflow
- Choose the runtime honestly — Expo with a development build gives you native modules and the Expo tooling. Expo Go is for prototypes; bare React Native is for teams that need full native control and are prepared to maintain it.
- Structure navigation first — Stacks inside tabs, with a typed route map. Retrofitting deep links into an untyped navigator is painful.
- Fix lists before they are slow —
FlashListwith a stablekeyExtractor, memoized row components, and a fixed item size where possible.ScrollViewwith a hundred children will drop frames on a mid-range Android. - Handle platform differences explicitly —
Platform.selectfor behavior, not just style. Back-button behavior, safe areas, and permission flows differ genuinely. - Move animation off the JS thread — Reanimated worklets run on the UI thread. Animating via
setStatewill jank the moment the JS thread does anything else. - Test the release build — Debug builds hide performance problems entirely. Profile in release, on a real mid-range device.
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.

react-native is a skill published in the GitHub repository nimadorostkar/Claude-Skills-collection (33 stars, last pushed 2d ago), licensed MIT. It adds 91 tokens to every session and 1,177 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-09-03.
