eva: Skill for Claude Code

.agents/skills/svg-animations/SKILL.md

svg-animations is a skill for Claude Code, Codex from vvedantb/eva. It costs 77 tokens per session (4,514 once invoked), scanned A, original, MIT.

A guide for creating animated SVG graphics, which are resolution-independent vector images made from shapes and paths.

In plain words
What is it for?
Use it for animated icons, logos, illustrations, loading indicators, path-drawing effects, and morphing shapes.
Why use it?
It helps you build SVG animations with controlled motion and performance instead of treating them as ordinary bitmap images.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is vvedantb/eva's own configuration. It tells Claude Code and Codex how to work on eva itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything eva configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

svg-animations 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 9d 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 — 446 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This skill guides creation of handcrafted SVG animations — from simple animated icons to complex multi-stage path animations. SVGs are a markup language for images; every element is a DOM node you can style, animate, and script.

SVG Fundamentals

Coordinate System

SVGs use a coordinate system defined by viewBox="minX minY width height". The viewBox is your canvas — all coordinates are relative to it, making SVGs resolution-independent.

<svg viewBox="0 0 200 200" xmlns="http://www.w3.org/2000/svg">
  <!-- 200x200 unit canvas, scales to any size -->
</svg>

Shape Primitives

<rect x="10" y="10" width="80" height="40" rx="4" fill="#1a1a1a" />
<circle cx="50" cy="50" r="30" fill="#e63946" />
<ellipse cx="50" cy="50" rx="40" ry="20" fill="#457b9d" />
<line x1="10" y1="10" x2="90" y2="90" stroke="#2a9d8f" stroke-width="2" />
<polygon points="50,5 95,90 5,90" fill="#e9c46a" />
<polyline points="10,80 40,20 70,60 100,10" fill="none" stroke="#264653" stroke-width="2" />

The <path> Element — The Power Tool

The d attribute defines a path using commands. Uppercase = absolute, lowercase = relative.

Command Purpose Syntax
M/m Move to M x y
L/l Line to L x y
H/h Horizontal line H x
V/v Vertical line V y
C/c Cubic bézier C x1 y1, x2 y2, x y
S/s Smooth cubic bézier S x2 y2, x y
Q/q Quadratic bézier Q x1 y1, x y
T/t Smooth quadratic T x y
A/a Elliptical arc A rx ry rotation large-arc sweep x y
Z/z Close path Z

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.
