# Ink Spot Illustrations

> A matched set of hand-inked spot illustrations for a site, newsletter or menu: nineteenth-century engraving, single-weight line or sumi brush. An image model draws them six to a sheet in black ink on white, and the script lifts each drawing off the paper as transparent ink, keeping fine hatching, then exports a PNG in every ink colour you list and an SVG that takes its colour from CSS.

- Output: Image, Transparent PNG in each ink · SVG in currentColor · 512 px WebP
- Price: $4.99 one-time, or included in Pro
- Page: https://lookbk.dev/skills/ink-spot-illustrations

## What you need

- Node.js 18 or newer. Nothing to install.
- Chrome, Chromium or Edge (the script finds it; set `CHROME_PATH` if it doesn't). It lifts the ink and makes the files.
- An image key in the environment: `GEMINI_API_KEY` (Gemini 3 Pro Image, "Nano Banana Pro", the default and what made the examples) or `OPENAI_API_KEY` (GPT Image). Without a key, the script writes `prompts.md` and you make the sheets in any image app and drop them in `sheets/`. A scan of real drawings on white paper works too.

## Install

```bash
curl -fsSL https://lookbk.dev/cli.js | node - add ink-spot-illustrations
```

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/ink-spot-illustrations` only, the one folder Claude Code reads.
- From your own terminal: `~/.agents/skills/ink-spot-illustrations`, which Codex, Gemini CLI, Copilot CLI, Cursor and OpenCode read, and also `~/.claude/skills/ink-spot-illustrations` 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.
