At a glance

Animate SVGs with SMIL, CSS keyframes, stroke drawing, shape morphing, and motion paths.

  • Adding motion to SVGs such as spinners
  • SKILL.md covers Choose the Animation Layer, Gotchas That Bite, The Stroke Drawing Trick and SMIL Timing and Easing, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Draw-in effects

What it does

SVG Animations is an agent skill from EpicenterHQ/epicenter. Animate SVGs with SMIL, CSS keyframes, stroke drawing, shape morphing, and motion paths. Use when adding motion to SVGs such as spinners, logos, draw-in effects, or morphing icons, not for static drawing or icon layout.

Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/recipes.md`).

It sits in Frontend & Design, covering Logo and visual identity. The repository describes itself as: Open-source, local-first apps.

When your agent uses it

  • Adding motion to SVGs such as spinners
  • Draw-in effects
  • Not for static drawing

Example prompts

  • “/svg-animations”

What it can do on your machine

Read from SKILL.md and the folder at commit 5b4bb69. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are svg and css).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

SVG Animations loads about 855 tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 59 tokens; SKILL.md has 349 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~855
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 349 words (~855 tokens).

“Handcrafted SVG animation. Every SVG element is a DOM node you can style, animate, and script; the craft is picking the right animation layer and dodging the handful of gotchas below.”
