Kami Document Design Skill

Skill by ara.so — Daily 2026 Skills collection.

Kami (紙, かみ) is an aesthetic constraint system for professional printed documents. It produces warm parchment canvas output across six document types, with Chinese and English variants, using a single ink-blue accent and editorial typography tuned for print.

What Kami Does

Kami is not a UI framework — it is a visual language applied to documents you actually want to read. It gives AI agents a strict design spec so every generated document shares the same signature: parchment background, ink-blue accent, serif for authority, sans for utility, tight editorial whitespace.

Six document types:

One-Pager — compact company/product intro, single page
Long Doc / White Paper — multi-section research or analysis
Letter — recommendation, cover, formal correspondence
Portfolio — project showcase, multi-page
Resume / CV — founder or professional CV
Slides — keynote-style deck, 4–8 slides

Each type has a Chinese variant and an English variant. Kami selects the correct variant based on the language you write in.

Design Tokens (Hard Rules)

Element	Value	Rule
Canvas	`#f5f4ed`	Warm parchment, never pure white
Accent	`#1B365D`	Ink blue only, no second chromatic hue
Neutrals	Yellow-brown undertone	No cool blue-grays
Serif weight	`500`	Never bold — single weight is the signature
Title line-height	`1.1–1.3`	Tight
Dense body	`1.4–1.45`	Captions, labels
Reading body	`1.5–1.55`	Paragraphs — never `1.6+`
Shadows	Ring or whisper only	No hard drop shadows
Tag backgrounds	Solid hex only	`rgba()` triggers WeasyPrint double-rectangle bug

Fonts:

Chinese: TsangerJinKai02 (serif) + Source Han Sans (sans). TsangerJinKai is free for personal use; commercial use requires a license from tsanger.cn.
English: Newsreader (serif, OFL) + Inter (sans, OFL)

HTML Document Structure

All Kami output is self-contained HTML rendered to PDF (via WeasyPrint or browser print). The canonical structure:

Prompt Patterns (What to Say)

The skill auto-triggers. Just describe your need naturally:

make a one-pager for my startup Acme — B2B SaaS for logistics, $2M ARR, 
Series A raise, targeting US mid-market. Include 3 key metrics.

---

build me a 6-slide deck for my talk on distributed tracing.
Include an architecture diagram and a quadrant comparing approaches.

---

write a recommendation letter from a CTO recommending Sarah Chen 
for a senior ML role. Formal, warm, two pages.

---

帮我做一份 Kaku 项目的作品集，6 页，中文，突出技术亮点和用户数据。

---

generate an Elon Musk style resume — founder CV, 2 pages, 
chronological, English.

Critical Rules for Generation

When generating any Kami document, the agent must enforce:

Never use
rgba()
for tag/badge backgrounds — use solid hex. WeasyPrint renders
```
rgba()
```
as a double rectangle.
Never use
font-weight: bold
or
700
on serif headings — lock at
```
500
```
.
Never use
line-height: 1.6
or higher on any element.
Never use pure white (
#ffffff
) as the page background — always
```
#f5f4ed
```
.
Never introduce a second chromatic color — the only accent is
```
#1B365D
```
. Variations are
```
#2c4a7a
```
(mid) and
```
#4a6fa5
```
(soft).

Always set

-webkit-print-color-adjust: exact; print-color-adjust: exact;

body

so backgrounds survive PDF export.

Always use
@page
with A4 margins unless the document type is Slides (use 16:9 or letter-landscape).

Slides layout: use

width: 254mm; height: 143mm;

per slide with

page-break-after: always

Rendering to PDF

Browser (recommended for demos):

File → Print → Save as PDF
Margins: None or Minimum
Background graphics: ✓ enabled

WeasyPrint (CI/server):

bash

pip install weasyprint
weasyprint document.html document.pdf

Node (Puppeteer):

const puppeteer = require('puppeteer');

async function htmlToPdf(htmlPath, pdfPath) {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  await page.goto(`file://${htmlPath}`, { waitUntil: 'networkidle0' });
  await page.pdf({
    path: pdfPath,
    format: 'A4',
    printBackground: true,   // critical for parchment canvas
    margin: { top: '0', right: '0', bottom: '0', left: '0' },
  });
  await browser.close();
}
