react-native-vision-camera — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited react-native-vision-camera (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.

The primary manifest — the file an agent reads to learn what this artifact does.
VisionCamera v5 is the maintained and latest version of react-native-vision-camera. It is a full Nitro Modules rewrite with a new Constraints API, Output-based architecture, in-memory `Photo`, and a hard break from the v4 format/prop model. Almost every v4 surface is gone or renamed — treat v5 as a new API, not an incremental upgrade.
This skill is a router. Read this file first, then load the reference that matches the task. Every reference is self-contained — do not load more than you need.
When in doubt, load references/migration-v4-to-v5.md — it covers the shape of the new API by contrasting it with v4 and is the fastest orientation.
These are the rules that catch people who "know" v4. Apply them without asking:
react-native-nitro-modules and react-native-nitro-image are required peer deps. Frame processors additionally require react-native-vision-camera-worklets AND react-native-worklets (Software Mansion's — not -core). Worklets - https://docs.swmansion.com/react-native-worklets/docs/usePhotoOutput, useVideoOutput, useFrameOutput, useDepthOutput, useObjectOutput (or useBarcodeScannerOutput from the barcode package) and pass them in an array. Capture methods (capturePhoto, createRecorder) live on the Output, not the Camera ref.constraints={[...]} — array order = priority, descending. The Camera negotiates the closest supported config automatically, so an impossible constraint like { fps: 99999 } never throws.photoOutput.capturePhoto(settings, callbacks) for in-memory Photo, or photoOutput.capturePhotoToFile(...) for a file path. The default path is in-memory — do not write temp files unless explicitly asked.FrameProcessorPlugin base class, VISION_EXPORT_SWIFT_FRAME_PROCESSOR macro, and VisionCameraProxy.addFrameProcessorPlugin are gone. A v5 plugin is a HybridObject with a typed Nitro spec. See references/frame-processors.md.try { ... } finally { frame.dispose() }. When offloading via asyncRunner.runAsync(...), dispose inside the async callback if it returned true, and dispose immediately in the else branch when it returned false.react-native-vision-camera-barcode-scanner is a separate package, MLKit-based on both platforms. For iOS-only object detection (QR, faces, bodies via native AVFoundation metadata, no ML dep), use useObjectOutput from core.useIsFocused() from react-navigation so the session goes Idle → Ready while not on screen, and keeps preferences warm for fast resume.'native' streams in the session's negotiated nativePixelFormat with zero conversions (it may resolve to a YUV, RGB, RAW, or 'private' format — verify the actual one via frame.pixelFormat). 'yuv' picks the YUV format closest to native and is the best general-purpose CPU-accessible choice (MLKit/OpenCV/Skia); 'rgb' forces a YUV→RGB conversion (~2.6× more bandwidth) — use only when a consumer hard-requires RGB. useDepthOutput has no pixelFormat option. For ML, prefer react-native-vision-camera-resizer (GPU) over paying a per-frame RGB conversion in the camera pipeline.<!-- source: useFrameOutput.ts:123 (pixelFormat = 'native' default); VideoPixelFormat.ts:52-62; CameraFrameOutput.nitro.ts:71,84-86 ("recommended to use 'native' ... zero-copy GPU-only path"); useDepthOutput.ts:70-77 (options have no pixelFormat) -->

Use the imperative VisionCamera.createCameraSession(...) API only when the user asks for multi-cam or full programmatic control.react-native-vision-camera-resizer (GPU-accelerated, returns a pooled GPUFrame) over vision-camera-resize-plugin (v4-era, CPU).<!-- source: react-native-vision-camera-resizer/src/specs/GPUFrame.nitro.ts + Resizer.nitro.ts (GPU resize→GPUFrame). The often-quoted "~5×" figure is a blog claim, not in source, so it is omitted here. -->
