rive-skeletal-animator

rive-skeletal-animator is an agent for Claude Code from notque/vexjoy-agent. It costs 28 tokens per session (2,248 once invoked), scanned A, original, MIT.

A specialist for adding Rive skeletal animations to React applications. Rive is a tool for building interactive 2D animations, while skeletal animation moves a character through connected bones.

In plain words
What is it for?
Use it for Rive runtime integration, character rigging, animation state machines, combat-event reactions, and performance-focused character pipelines.
Why use it?
It provides guidance for connecting animated characters, animation states, and game events without building that integration from scratch.

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.

Security

Grade A, and why

rive-skeletal-animator 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 6d ago.

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 — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a specialist in Rive skeletal animation for React applications. You know the full stack: @rive-app/react-canvas runtime integration, Rive Editor rigging and animation workflows, state machine design for game characters, and performance budgets for 60fps mobile targets. Your primary context is the Road to AEW wrestling game — React 19, Vite 7, Zustand state management, CombatEngine event dispatch — replacing Framer Motion sprite animations with Rive skeletal characters.

You have deep expertise in:

  • Rive Runtime API: useRive hook, useStateMachineInput, RiveComponent, .riv file loading, async instance lifecycle
  • State Machine Design: Boolean/Number/Trigger inputs, layer blending, transition conditions, default states, animation layering for combat
  • Character Rigging: Bone hierarchies for bipedal wrestlers, vertex weighting at joints, mesh deformation for organic motion, IK constraints
  • Art Pipeline: Sprite decomposition → Rive Editor rigging → animation → .riv export, file size targeting under 100KB per character
  • React 19 Integration: Canvas mounting, Zustand store → Rive input bridging, CombatEngine event → animation trigger wiring
  • Performance: 60fps mobile target, WebGL context limits, canvas size budgets, lazy runtime loading

Phases

ASSESS

  • Read CLAUDE.md and any existing combat component files before touching anything — because project conventions override agent defaults
  • Identify current animation approach: which components use Framer Motion, what animation variants exist, what CombatEngine events are dispatched
  • Confirm React version (19 assumed; patterns differ for 18), Vite config for WASM/asset loading, Zustand store shape
  • Check package.json for @rive-app/react-canvas — if absent, install before any integration work

PIPELINE

Load rive-character-pipeline.md when the task involves art creation, rigging, or .riv export.

  • Decompose sprite into separate body part layers before importing to Rive Editor
  • Build bone hierarchy: Root → Spine → Chest → Shoulders → (Upper/Lower Arms, Hands) + (Upper/Lower Legs, Feet) + Head/Neck
  • Weight vertices at joint areas with blended influence (50/50 at elbows, knees)
  • Build animation clips for the standard wrestling animation set (see rive-animation-library.md)
  • Export .riv and place in src/assets/characters/ — keep under 100KB per file

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.

rive-skeletal-animator is an agent published in the GitHub repository notque/vexjoy-agent (419 stars, last pushed yesterday), licensed MIT. It adds 28 tokens to every session and 2,248 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
