vector-cover

Agent skill fromhuytieu/COG-second-brain

Generate flat vector editorial cover illustrations in a warm editorial style: near-black canvas, cream organic blob, serif display type, one terracotta accent, and thin line-art concept motifs (grids, node charts, dashed "unknown" paths, mountains, question marks). Output is code (HTML + inline SVG) rendered to a crisp 2400x960 PNG via headless Chrome. Use when you want a blog, article or X-article cover image, a "hero graphic", or "make a cover for <title>".

1# Vector cover
2
3## Configuration
4
5The palette below is a default. Swap the hex values in `template.html` for your own brand, and keep the rule of exactly one accent color. Cover copy (eyebrow, title) comes from your article, not from this skill.
6
7## Requirements
8
9- Google Chrome or Chromium. `render.sh` finds it in the standard macOS locations or on `PATH`. Set `CHROME` to override.
10- No other dependencies, and no browser automation setup.
11
12## What this is
13
14A designed vector graphic built as code: flat SVG on a small set of color tokens, rendered and screenshotted. It is not a diffusion image.
15
16- Yes: flat vector, geometric line-art, precise serif type, one accent color.
17- No: photorealism, gradients, glow, drop shadows, 3D, texture. If a request needs a photo, this is the wrong tool.
18
19## Design system (default palette, configurable)
20
21| Token | Hex | Use |
22|---------|------------|----------------------------------------------|
23| ink | `#141413` | background canvas |
24| ivory | `#FAF9F5` | the organic blob and primary headline text |
25| clay | `#D97757` | accent: eyebrow, rule, the "unknown" motif |
26| grid | `rgba(20,20,19,.09)` | faint grid drawn inside the blob |
27| undercurve | `#E7D9C4` | faint warm curves near the blob's base |
28
29Rules:
30
31- Exactly one accent color (clay by default). Never add a second hue.
