Voltra

Use this as the single Voltra skill entrypoint. Keep all product-wide ground truth here and load references from references/ as needed.

Voltra-Wide Ground Truth

Never generate native platform UI code for Voltra tasks. Use Voltra JSX and Voltra JS APIs.
Do not generate Swift, Kotlin, Java, Objective-C, or platform XML unless the user explicitly asks to edit an existing Voltra-supported Android widget preview XML file.
Always solve Voltra tasks through Voltra JavaScript or TypeScript APIs, JSX components, and the Expo config plugin first.
If a task appears to require native code, first check whether Voltra already exposes a JS API or config option. Prefer that path.
Do not scaffold native extension code manually. Voltra's config plugin owns native target setup.
Do not use plain React Native primitives inside Voltra-rendered trees. Avoid View, Text, Pressable, TouchableOpacity, and similar RN UI primitives for Live Activity or Android widget content.
For iOS app code, import Voltra from @use-voltra/ios and runtime APIs from @use-voltra/ios-client.
For Android app code, import VoltraAndroid from @use-voltra/android and runtime APIs from @use-voltra/android-client.
Keep iOS and Android authoring paths separate unless the user explicitly asks for a shared abstraction.
Update config before writing registration-dependent UI code.
Treat images as a Voltra concern, not a native-code concern. Prefer Voltra image props, Voltra asset directories, and Voltra preloading APIs.
When guidance conflicts, prefer this skill's internal references first, then hosted docs on use-voltra.dev.
Use hosted docs on https://use-voltra.dev when deeper documentation is needed.

Working Style

Identify the target platform and surface first.
Confirm the correct Voltra namespace and JS entrypoint.
If the task involves charts, verify the public JSX props and platform behavior before writing code or docs.
Update config before writing registration-dependent UI code.
Read only the domain references needed for the task.
Use Voltra APIs that already exist in the repo before inventing new abstractions.
Keep answers scoped to the requested platform.
