What it does
React Native Vision Camera is an agent skill from margelo/react-native-skills. Best-practices guide for React Native VisionCamera v5 setup, migration, capture, controls, outputs, and basic frame processing. Use the separate react-native-vision-camera-realtime skill for production low-latency GPU, ML, CV, Skia or WebGPU pipelines and frame-coupled overlays.
Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `references/advanced-features.md`, `references/capture-and-controls.md` and `references/frame-processors.md`).
It sits in Mobile, covering Cross-platform mobile apps. It works with React Native. The repository describes itself as: The best react-native Agent Skills. Forget 10x, this is 100x.

Workflow steps
9 steps, taken from the first numbered list in SKILL.md.

- outputs={[...]} replaces photo / video / frameProcessor / codeScanner props. Create outputs with usePhotoOutput, useVideoOutput…
- There is no format prop and no useCameraFormat. Use constraints={[...]} — array order = priority, descending. The Camera negotiates the…
- takePhoto() does not exist. Use photoOutput.capturePhoto(settings, callbacks) for in-memory Photo, or photoOutput.capturePhotoToFile(...)…
- Frame Processor plugins must be Nitro Modules. The v4 FrameProcessorPlugin base class, VISION_EXPORT_SWIFT_FRAME_PROCESSOR macro, and…
- Every Frame (and Depth) MUST be .dispose()d. The buffer pool is bounded; leaking a frame stalls the pipeline. Wrap work in try { ... }…

What it can do on your machine
Read from SKILL.md and the folder at commit 1e9e17b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
gh
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
visioncamera.margelo.comdocs.swmansion.comblog.margelo.comgithub.comvisioncamera4.margelo.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
React Native Vision Camera loads about 2.2k tokens when it runs, and up to ~24k if it reads all its reference files. Until then it costs about 77 tokens; SKILL.md has 914 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 914 words (~2,197 tokens).
“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…”
