nitro-fetch — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited nitro-fetch (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

A focused reference for AI coding assistants working in a project that uses the react-native-nitro-fetch family of packages. Answer using the real APIs from this repo — not invented ones — by routing to the matching references/*.md file below.
react-native-nitro-fetch is a drop-in, native-backed replacement for the browser networking stack on React Native:
fetch — WHATWG-compatible, backed by URLSession (iOS) and Cronet (Android) via Nitro Modules.NitroWebSocket — native WebSocket (libwebsockets + mbedTLS and default in case of iOS) with the same shape as the browser WebSocket.NitroTextDecoder — native UTF-8 decoder that beats the Expo backed JS polyfill.The performance story has three moving parts, and most questions end up being about one of them:
prefetchOnAppStart(...) and prewarmOnAppStart(...) replay stored requests / socket opens on every cold start, so by the time JS runs the response is already cached or the socket is already OPEN.import { fetch } from 'react-native-nitro-fetch', import { NitroWebSocket } from 'react-native-nitro-websockets', or plugging into axios via a custom adapter. Alternatively, users can do a global replace (globalThis.fetch = fetch, etc.) at the top of their entry file — see the Global Replace docs for setup and trade-offs.NetworkInspector records HTTP + WS activity at the JS boundary; native Perfetto / Instruments traces cover everything below that (DNS, TLS, TTFB, body). One is for correctness, the other is for latency.Load the matching file from references/ before writing code. Each reference cites real file paths in this repo.

npm install react-native-nitro-fetch react-native-nitro-modules
# optional, for WebSockets and TextDecoder:
npm install react-native-nitro-websockets react-native-nitro-text-decoderAfter install, rebuild the app (pod install for iOS, a fresh ./gradlew build for Android). Nothing else is wired automatically — turning any of this on is opt-in through the reference files above.
A correct answer for any of these will cite the API and file path. A wrong / hallucinated answer will invent an install(), setup(), or init() helper that doesn't exist in this repo.
