2 things to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
  • 3 stars3 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Use this skill for lottie-react-native and dotLottie native assets, Expo compatibility, asset bundling, refs, playback control, accessibility, reduced motion, and platform validation. Trigger on lottie-react-native, dotLottie React Native, LottieView, .lottie native, After Effects native animation. Do not use for near-miss tasks outside these boundaries; route to adjacent motion or platform skills when they own the implementation.

The file declares its own license as MIT. That is the author’s claim about this one file, and it is not the same thing as the license GitHub reports for the repository, which is listed with the other numbers below.

Native Lottie

lottie-react-native and dotLottie native assets, Expo compatibility, asset bundling, refs, playback control, accessibility, reduced motion, and platform validation.

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 Do not cite local scrape paths, machine cache paths, or hidden source locations.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-lottie for browser Lottie.
  • Use native-rive for interactive Rive state machines.
  • Use native-motion-core for code-driven Reanimated motion.

Workflow

  1. Check Expo SDK package compatibility and asset format.
  2. Bundle assets through the app asset pipeline.
  3. Own playback refs, pause/stop behavior, and unmount cleanup.
  4. Validate Android/iOS rendering, reduced motion, and accessibility labels.

Gotchas

  • Large JSON animations can hurt startup and memory.
  • Autoplay loops need pause/reduced-motion behavior.
  • Native asset paths differ from web URLs and need bundler-safe imports.

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-lottie-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.
