# Ringed Planet Hero

> A ringed gas giant hanging beside your headline in a field of stars. Its cloud bands drift in alternating jets and a great storm turns in one belt; its rings, tilted open toward you with fine ringlets and a dark gap, pass in front of the planet below and behind it above, throw a shadow band across its face, and lose a wedge to the planet's shadow on the night side. Moons circle once a loop, crossing in front of the planet and slipping behind it, while stars twinkle and a faint nebula drifts. Your agent sets the cloud, ring and moon colors, the tilt and the light, fonts, logo, headline and buttons, checks contrast at four widths and records a seamless 1080p loop.

- Output: Web, Animated WebGL hero · page + embed + 1080p video
- Price: $6.90 one-time, or included in Pro
- Page: https://lookbk.dev/skills/ringed-planet-hero

## What you need

- Node.js 18 or newer. Nothing to install.
- Chrome, Chromium or Edge, for the checks and the recording (the scripts find it; set `CHROME_PATH` if they don't).
- ffmpeg, for the video (`brew install ffmpeg`, `winget install ffmpeg`, `apt install ffmpeg`; or set `FFMPEG_PATH`).
- At runtime, nothing but WebGL: the shader is inlined in the page. Fonts load from jsDelivr (the pinned list) or Google Fonts; without the network the page uses system fonts. Without WebGL visitors see the still.

## Install

```bash
curl -fsSL https://lookbk.dev/cli.js | node - add ringed-planet-hero
```

The first run prints a sign-in link; open it, approve, and run the command again. Pro skills install for accounts that bought them or have Pro.

Where it installs:

- Run by Claude Code: `~/.claude/skills/ringed-planet-hero` only, the one folder Claude Code reads.
- From your own terminal: `~/.agents/skills/ringed-planet-hero`, which Codex, Gemini CLI, Copilot CLI, Cursor and OpenCode read, and also `~/.claude/skills/ringed-planet-hero` when `~/.claude` exists.

Add `--claude` or `--shared` to write only one of those folders, or `--project` to install into the current folder instead. Start a new agent session afterwards so it picks up the skill.
