Native Rive

Rive React Native/Nitro runtime, .riv assets, state machines, inputs, asset loading, platform compatibility, accessibility, and iOS/Android proof.

Operating Contract

Use this skill as a compact router plus domain checklist. Load references only when the current task matches their condition. Do not cite local scrape paths, machine cache paths, or hidden source locations. Verify API details against the target repo's installed package versions before editing.

Source Order

1. Inspect the target repo's installed packages, framework/runtime versions, local design tokens, accessibility policy, and existing motion patterns.
2. Use the bundled references below for skill-specific gotchas and copied source excerpts.
3. Use official current docs/package source as API truth when local code or bundled notes are version-sensitive.

Decision Boundaries

• Use web-rive for browser runtime.
• Use native-lottie for Lottie/dotLottie assets.
• Use native-motion-core for code-driven Reanimated motion.

Workflow

1. Check package/runtime compatibility and native build requirements.
2. Verify asset path, state machine name, input names, and autoplay.
3. Map app state to inputs with cleanup on unmount.
4. Validate iOS/Android build/rendering and accessibility fallback.

Gotchas

• State machine names and inputs are asset contracts.
• Native Rive runtime may require development build proof, not only Expo Go.
• Canvas-like output needs surrounding accessible semantics.

Bundled Resources

• references/rive-native-state-machines.md - Native Rive state-machine contract. Read when binding inputs, triggers, or state machine names.

Audit CLI

node scripts/audit.mjs doctor --root . --format json
node scripts/audit.mjs scan --root . --format markdown
node scripts/audit.mjs scan --root . --format json --output native-rive-audit.json

Treat script findings as leads. Verify every finding against current code before changing behavior or reporting it as valid.

Closeout

Before finalizing, run the repo's focused validation command, this skill's audit CLI when relevant, and any browser/device/manual proof required by the changed surface. Report commands run, findings fixed, findings skipped with reasons, and residual risk.
