rueca SKILL.md skillA
rueca from rueca/rueca is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add rueca/rueca/rueca@git:20261016.fac095dPins git:20261016.fac095d in mdr.lock. Pin the fingerprint instead.

Build the design-tool harness around an interactive visual prototype — inspector of sliders and knobs, timeline, layers, presets, undo, share link, export. Use when someone wants to tweak, tune, scrub, dial in or play with how something looks or moves — a motion study, canvas / WebGL / three.js / p5 sketch, shader, SVG or generative art, photo effect, UI component, UX flow, node graph, playground, client demo — in any runtime, new or existing. Also use unasked when sketching an animation, logo…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Rueca
A prototype needs two things: **the artifact** (the screen, animation, shader, flow)
and **the harness** around it — the tool that lets someone feel it and tune it. This
skill builds the harness. When someone wants to feel or tune a visual prototype, build the
harness, not just the artifact: a prototype with no controls is a screenshot.
The harness is a **design tool**, not a web page. It should feel like Figma, Framer,
Spline, Paper, Affinity or Rive — and it stays **neutral**, so whatever is being
designed reads truthfully inside the artboard.
**Read this file, then build.** It holds everything a typical tool needs. Open a
reference when the table at the end says to, not up front. Each one
you read rides along in every later turn.
## Workflow
1. **Identify the artifact and its runtime** — Canvas 2D, WebGL/three.js, SVG, DOM/React,
an existing page or app — and who uses the tool (the designer, or a client).
2. **Pick the route by the project the tool lives in**, not by what you can run this session.
- **The kit**: a React 19 + Tailwind v4 project, or a new one (Next.js too: render the tool
client-only, see install.md). Install it with
…Read the whole file at its exact version.
How to install
mdr add rueca/rueca/rueca@sha256:06afb133d2d62b05The line at the top of this page pins the label git:20261016.fac095d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
