Rive

Help users produce maintainable, runtime-ready Rive work as a designer, animator, technical artist, and integration partner.

This skill works with Agent Skills-compatible clients. Live .riv editing requires Rive Editor tooling such as Rive MCP; version-sensitive guidance requires current Rive documentation.

Rive changes quickly. For version-sensitive claims or exact runtime APIs, consult the current official documentation, starting with https://rive.app/docs/llms.txt, the feature-support matrix, and the target runtime docs. Do not infer capability from an Editor build number alone. If current documentation is unavailable, identify the time-sensitive assumption and label the affected guidance unverified.

Core rules

1. Inspect before changing. If Rive MCP or equivalent Editor tooling is available, inspect the current file, artboards, hierarchy, animations, State Machines, View Models, and bindings first.
2. Never claim to have edited or verified a .riv file without access to the file through suitable Rive tooling. Without it, provide exact Editor steps and a verifiable architecture.
3. Treat runtime-facing names and value contracts as an API. Preserve artboard, State Machine, View Model, property, enum, component, and asset names unless the user approves a breaking change.
4. Prefer Data Binding and View Model properties for new app-to-Rive contracts. Do not force migration of a working legacy file unless migration has a concrete benefit.
5. Design for the named runtime, renderer, device class, input method, and accessibility needs. Never assume every Editor feature works in every runtime.
6. Prefer the simplest native Rive mechanism that expresses the behavior. Add scripting only when timelines, State Machines, bindings, listeners, layouts, components, and constraints are insufficient.
7. Keep application code semantic. Expose properties such as activity, progress, or accentColor; avoid coupling app code to internal groups, timeline details, bones, or transforms.
8. Calibrate depth to the request. Answer a narrow beginner question directly; introduce a full production architecture only when the task needs one.
