Yes. Create a free AdAnt account to download the ZIP. There is no card and no trial timer, and the original is public on GitHub, linked on this page.

No key. Setup downloads Playwright from npm (and runs fsevents' install script on a Mac), and Playwright downloads Chromium from its own CDN. Every page the skill writes links its fonts from Google, so rendering and opening one contact fonts.googleapis.com and fonts.gstatic.com. If they can't be reached, the page falls back to other fonts with no warning, so check the PNG. The skill also tells your agent to research missing figures, using whatever web access your agent has. Run setup yourself, as the install note says: SKILL.md lists npm install and the Chromium download as first-time setup, and brew or apt for FFmpeg, without telling your agent to ask you first.

Three Node scripts. check.mjs and render.mjs start headless Chromium. animate.mjs starts Chromium and FFmpeg, or the program the FFMPEG environment variable names, and writes its frames to a temporary folder that it deletes afterwards. render.mjs and animate.mjs replace any file already at the output path without asking. We found no telemetry, analytics or uploads. The MP4s and GIFs have no sound.

Yes, every file in the ZIP: SKILL.md, all references, all twelve design languages, the template and the three scripts. It is someone else's code, so read it before you trust it.

Everything outside the skill's own folder: the examples (66 files, 79 MB), the README, the contributing and security notes, a planning document, the plugin manifests, and the repository's own scripts and CI. The skill does not use them, and they stay public in the original repository. Every file we kept is unchanged.

No. All three scripts open the HTML in Chromium with JavaScript on and no filter on what it loads, so someone else's page could run its own code in that browser and send requests to any address while it renders. SKILL.md tells your agent to link nothing but Google Fonts, but no script enforces that, and the layout checker doesn't look for it. Render only pages you or your agent wrote.

Three of the twelve style files name a reference for their look. cutaway opens with a Dorling Kindersley / Stephen Biesty "Incredible Cross-Sections" plate, park-poster names the WPA posters and the modern Fifty-Nine Parks series, and isometric-world says "SimCity meets an explainer". Each aims for that kind of look with its own colors, fonts and rules, and none tells your agent to copy a specific picture. For commercial work, don't ask your agent to match those people's or companies' pieces or use their names in your prompts or credits, or pick one of the other nine styles.

They come from one published estimate, on the USGS Water Science School page "Where is Earth's Water?" (Shiklomanov, in Gleick, 1993): 2.5% of Earth's water is fresh, and of that 68.7% is ice, glaciers and permanent snow, 30.1% is ground water and a little over 1.2% is surface water. The 97.5% and the 0.03% are our own arithmetic (100 - 2.5, and 2.5% x 1.2%). Read the 0.03% as a broad figure: in the USGS table, most of that 1.2% is ground ice and permafrost, and the same page puts rivers and lakes at about 1/150th of one percent of all water, near 0.007%. The graphic doesn't draw that line. It shows the format, so don't cite it as a source.

We couldn't check all of them. The style files say their palettes pass color-blind checks, but the checker isn't in the repository, so we couldn't repeat that, and a few slots state contrast under 3:1 with a rule to always label them. Its notes on what audiences liked come with no data. The layout checker is real and measures text, not whether the numbers are right, so check every figure yourself.
