react-native-true-sheet: Skill for Claude Code

.agents/skills/preview/SKILL.md

preview is a skill for Claude Code, Codex from lodev09/react-native-true-sheet. It costs 108 tokens per session (3,876 once invoked), scanned A, original, MIT.

A workflow for recording an example mobile app on an iOS simulator, Android emulator, iPad, or mobile Safari and rendering the recording as README images and documentation video.

In plain words
What is it for?
It helps drive the example app, capture its screen, and create light and dark GIFs plus an MP4 for docs and blog posts.
Why use it?
It avoids inconsistent demo recordings and prepares separate outputs for GitHub pages and written documentation.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is lodev09/react-native-true-sheet's own configuration. It tells Claude Code and Codex how to work on react-native-true-sheet itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything react-native-true-sheet configures →

About the project

React Native TrueSheet is a React Native component that provides native bottom sheets and related side-sheet interfaces on iOS, Android, and the web. It is for developers building mobile or cross-platform app interfaces with modals, navigation, scrolling content, and keyboard-aware layouts. The catalogue instructions and skill support development with this component.

Token cost

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.

Fable 5.1 $0.00108 $0.03876
Opus 5.5 $0.00043 $0.01550

Security

Grade A, and why

preview 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/render.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 198 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Preview

Previews are scripted screen recordings of the example app, rendered by scripts/render.sh into:

File Used by Look
<name>-light.gif, <name>-dark.gif README (GitHub) Device frame and shadow, matted to GitHub's white and #0d1117 pages
<name>.mp4 Docs and blog Plain screen; the docs frame it with CSS, so it fits both themes

GIF has no soft transparency, so each theme gets its own GIF and the README picks one with <picture>. Files go in docs/public/img/previews/.

Read argent-device-interact and argent-screen-recording before driving a device.

1. Prepare

Release build

Record a Release build of the bare example: no Metro, no LogBox or dev overlays, and production-speed JS, so animations don't drop frames. MapScreen's on-screen event log renders only in __DEV__, so it's gone too. The JS bundle is baked in at build time: make any example change first, and rebuild after every JS change.

iOS, from example/bare/ios (then install build/Build/Products/Release-iphonesimulator/TrueSheetExample.app with argent reinstall-app):

xcodebuild -workspace TrueSheetExample.xcworkspace -scheme TrueSheetExample \
  -configuration Release -destination 'id=<UDID>' -derivedDataPath build build \
  > /tmp/truesheet-xcodebuild-release.log 2>&1; echo "EXIT $?"

Android, from example/bare/android, with the emulator booted on the hardware GPU (e2e skill §1). Release is signed with the debug keystore, so this builds and installs in one step (about 3 min clean). Gradle only watches example/bare for the JS bundle and calls it up to date after an example/shared edit, so always rerun the bundle task:

./gradlew app:createBundleReleaseJsAndAssets --rerun app:installRelease -PreactNativeArchitectures=arm64-v8a

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
