Reviews React Native TV apps for focus/D-pad navigation, 10-foot UI layout, TV playback/DRM integration, low-memory TV performance, and TV accessibility. Use when building, debugging, or reviewing react-native-tvos, Expo TV, Amazon Vega/Kepler, or React Native web TV targets where the issue depends on remote input, TV focus, TV packaging, TV hardware, or TV playback constraints.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a comprehensive set of best practices for building, testing, and debugging React Native applications on TV platforms, including Apple TV, Android TV, Fire TV, and web-based targets. It focuses on the unique challenges of the 10-foot UI, such as remote-based D-pad navigation, focus management, TV-specific performance constraints, and accessibility requirements. The guidance helps developers navigate the differences between various TV stacks like react-native-tvos and Amazon Vega/Kepler.

What it does

Provides heuristics for 10-foot UI design, typography, and layout.
Offers strategies for managing focus engines and D-pad navigation.
Details performance optimization for low-memory TV hardware.
Outlines requirements for TV-specific accessibility and screen reader support.
Explains how to handle video playback, DRM, and player controls.
Guides developers on identifying and setting up the correct TV platform stack.

When to use it

When building or debugging navigation issues related to remote inputs.
When optimizing app performance for low-memory TV devices.
When implementing accessibility features for TV screen readers.
When troubleshooting video playback or DRM integration errors.
When designing layouts for 10-foot viewing distances.

Advantages

Reduces platform-specific bugs by providing clear stack-detection rules.
Improves user experience through consistent focus and navigation patterns.
Helps meet accessibility standards required for TV app store approval.
Provides actionable debugging paths for common TV-specific failures.

Usage examples

“How do I fix focus jumping to the wrong element in my React Native TV app?”: The agent will guide you to use focus-management.md, recommending the use of TVFocusGuideView for shared focus paths and advising against imperative focus overrides.
“My app crashes on Fire TV when scrolling through a long list of posters. What should I check?”: The agent will point you to perf-lists.md and perf-memory.md to implement proper virtualization and optimize image memory usage for low-memory hardware.

React Native TV Best Practices

Overview

TV-specific review guidance for React Native-backed apps on Apple TV, Android TV, Fire TV, Amazon Vega/Kepler, and web-based TV targets such as Tizen or webOS.

Use this skill only for TV deltas: remote input, focus engines, 10-foot layout, platform packaging, playback/DRM, low-memory TV hardware, and TV accessibility. For ordinary React Native performance or architecture issues, use react-native-best-practices.

Skill Format

Reference files are grouped by topic prefix:

focus-*: focus engines, focus guides, focus event performance
nav-*: D-pad navigation, Back/Menu behavior, keyboard/search input
design-*: 10-foot typography, layout, color, focus visibility
perf-*: startup, memory, lists, animation, and network constraints on TV hardware
video-*: playback architecture, DRM/protocol selection, debugging
a11y-*: TV accessibility implementation and audit checks
setup-*: stack detection, setup, architecture, cross-platform behavior
test-* and release-*: test coverage, E2E, and CI/release workflows

When to Apply

Apply this skill when the app targets a TV platform and the work involves:

Focus movement, visible focus, focus restoration, or remote/D-pad input
TV layout readability, overscan/safe areas, or 10-foot UI density
TV player controls, manifests, DRM, decoder support, or playback errors
Performance on low-memory TV hardware, especially with video or large carousels
TV accessibility with screen readers, captions, focus order, or remote-only interaction
Platform setup for react-native-tvos, Expo TV, Amazon Vega/Kepler, Tizen, or webOS

Before You Start — Identify the TV Stack

This skill covers several TV stacks. Detect which one the app targets before flagging setup issues — demanding react-native-tvos, a tvOS Podfile, or an Android TV manifest on a Vega/Kepler or web-based TV app produces false positives.

Stack	How to detect	Setup expectations
react-native-tvos (Apple TV, Android TV, Fire TV)	`"react-native": "npm:react-native-tvos@…"` in package.json	tvOS Podfile (`platform :tvos`); Android TV `leanback`/`LEANBACK_LAUNCHER` manifest entries; TV emulator/simulator
Expo + react-native-tvos	above plus `@react-native-tvos/config-tv` in app.json	`EXPO_TV=1` prebuild; `react-native-tvos` version must match the Expo SDK; not all Expo features/libraries are available on TV
Amazon Vega / Kepler	Vega/Kepler SDK & tooling (`@amazon-devices/*` deps, Kepler manifest); no `react-native-tvos`	Amazon's Vega/Kepler toolchain — `react-native-tvos`, tvOS Podfile, and Android TV manifest do not apply
Web-based TV (Tizen, webOS)	web bundler (Rsbuild/webpack) + platform packaging; spatial-nav library	Platform SDK packaging; `@noriginmedia/norigin-spatial-navigation` for focus

The focus, 10-foot design, performance, accessibility, and player guidance applies across all of these — only the setup/build expectations are stack-specific.

Review Rules

Resolve the target stack before setup advice.
Prefer natural focus order and focus guides before imperative focus calls or broad nextFocus* maps.
Treat focus loss, invisible focus, and broken Back/Menu behavior as navigation bugs.
Check readability, safe areas, and focus states at TV distance before tuning visual details.
Profile on the weakest supported TV device before reporting performance fixes as complete.
Separate playback failures by layer: manifest request, DRM license exchange, decoder capability, player state, and React UI controls.

Priority-Ordered Guidelines

Priority	Category	Impact	Prefix
1	Focus and D-pad navigation	CRITICAL	`focus-`, `nav-`
2	List, animation, and input performance	CRITICAL	`perf-*`
3	Playback and DRM failures	HIGH	`video-*`
4	10-foot readability and layout	HIGH	`design-*`
5	TV accessibility	HIGH	`a11y-*`
6	Stack setup, testing, and release	MEDIUM	`setup-`, `test-`, `release-*`

Quick Reference

Detect the TV stack from package files, manifests, native folders, and platform tooling.
Reproduce navigation with the remote or D-pad path, not mouse/touch assumptions.
Confirm the focused element is always visible, reachable, and restored after modals/routes.
Check playback failures from the network/DRM layer upward before changing React controls.
Measure list, animation, memory, and startup work on the weakest supported TV target.

"App freezes when scrolling lists"	perf-lists.md → Virtualization
"Animations stutter on Fire TV"	perf-animations.md → Native driver
"Text too small on TV"	design-typography.md → Minimum sizes
"Video won't play / DRM errors"	video-streaming.md → DRM section
"Screen reader skips elements"	a11y-implementation.md → Roles & labels
"Back button doesn't work right"	nav-patterns.md → Back navigation
"Keyboard covers content"	nav-keyboard.md → Built-in vs custom
"App takes forever to start"	perf-overview.md → Startup time
"Images causing memory crashes"	perf-memory.md → Image optimization
"CI pipeline takes hours"	release-cicd.md → Fingerprinting
"How to share code across platforms"	setup-architecture.md → Code sharing

Security (TV-Specific)

General dependency/input hygiene applies as in any RN app; the TV-specific deltas worth calling out:

Never embed FairPlay/Widevine/PlayReady keys in client code — treat the license server as the trust boundary and keep DRM tokens server-issued.
