vector-cover SKILL.md skillA

This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.

vector-cover from huytieu/cog-second-brain is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add huytieu/cog-second-brain/vector-cover@git:20261023.65f43f1

Pins git:20261023.65f43f1 in mdr.lock. Pin the fingerprint instead.

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>".

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Vector cover

## Configuration

The 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.

## Requirements

- Google Chrome or Chromium. `render.sh` finds it in the standard macOS locations or on `PATH`. Set `CHROME` to override.
- No other dependencies, and no browser automation setup.

## What this is

A designed vector graphic built as code: flat SVG on a small set of color tokens, rendered and screenshotted. It is not a diffusion image.

- Yes: flat vector, geometric line-art, precise serif type, one accent color.
- No: photorealism, gradients, glow, drop shadows, 3D, texture. If a request needs a photo, this is the wrong tool.

## Design system (default palette, configurable)

| Token   | Hex        | Use                                          |
|---------|------------|----------------------------------------------|
| ink     | `#141413`  | background canvas                            |
| ivory   | `#FAF9F5`  | the organic blob and primary headline text   |

How to install

The exact contents, by fingerprint

mdr add huytieu/cog-second-brain/vector-cover@sha256:f5fe6610c439af91

The line at the top of this page pins the label git:20261023.65f43f1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
