# restart Claude Code — skill registers as `diagram-design`
```
Or symlink from another location:
```bash
git clone git@github.com:cathrynlavery/diagram-design.git ~/code/diagram-design
ln -s ~/code/diagram-design ~/.claude/skills/diagram-design
```

## The 13 Diagram Types
| Type | Use when… |
|---|---|
| **Architecture** | Components + connections (services, APIs, infra) |
| **Flowchart** | Decision logic, yes/no branches |
| **Sequence** | Messages over time (OAuth, API calls, user flows) |
| **State machine** | States + transitions (order lifecycle, auth states) |
| **ER / data model** | Entities + fields + relationships |
| **Timeline** | Events on a horizontal or vertical axis |
| **Swimlane** | Cross-functional flows (who does what, when) |
| **Quadrant** | Two-axis positioning (impact vs effort, risk vs value) |
| **Nested** | Hierarchy by containment (layers inside layers) |
| **Tree** | Parent → children (org chart, file tree, decision tree) |
| **Layer stack** | Stacked abstractions (OSI model, tech stack) |
| **Venn** | Set overlap (2–3 circles) |
| **Pyramid / funnel** | Ranked hierarchy or conversion drop-off |
**Selection rule:** ask "would a reader learn more from this than from a well-written paragraph?" If no, don't draw. Default to deletion over addition.

## Quickstart
```
# In Claude Code — just describe what you need:
"Make me an architecture diagram: frontend, backend, Postgres, Redis cache."
"I need a quadrant of Q2 projects by impact vs effort."
"Give me a sequence diagram of the OAuth 2.0 handshake."
"Draw a state machine for an e-commerce order: pending → paid → shipped → delivered."
"Timeline of the Roman Empire's key turning points."
```
Claude picks the right type, builds HTML, saves the file. To use a template directly:
```bash
cp assets/template.html my-diagram.html # minimal light
cp assets/template-full.html my-diagram.html # editorial with summary cards
```

## Brand Onboarding (60 seconds)
Without onboarding, diagrams render in neutral stone + rust (warm off-white paper, charcoal ink, rust-orange accent). Run onboarding to match your site:
```
"onboard diagram-design to https://yoursite.com"
```
Claude will:
1. Fetch your homepage
2. Extract dominant palette + font stack
3. Map values to semantic roles: `paper`, `ink`, `muted`, `accent`, `link`
4. Run WCAG AA contrast checks (auto-adjusts failures)
5. Show a proposed diff → write tokens to `references/style-guide.md`
### What gets extracted
| Detected from your site | Becomes |
|---|---|
| `<body>` background | `paper` token |
| Primary text color | `ink` token |
| Secondary / caption text | `muted` token |
| Cards or containers | `paper-2` token |
| Most-used brand color (CTA, link, heading) | `accent` token |
| `<h1>` font family | `title` font |
| `<body>` font family | `node-name` font |
| `<code>` / `<pre>` font | `sublabel` font |
### Manual token override
Edit `references/style-guide.md` directly:
```markdown
| Token | Value | Role |
|------------|-----------|-------------------------------|
| paper | #F8F5F0 | diagram background |
| ink | #1A1A1A | primary text, borders |
| muted | #6B6560 | secondary labels, grid lines |
| paper-2 | #EEEAE4 | card fills, lane backgrounds |
| accent | #B5523A | focal nodes, 1–2 per diagram |
| accent-fg | #FFFFFF | text on accent-colored nodes |
```
**First-run gate:** on first use in a new project, if `style-guide.md` is still at default, Claude pauses and asks: *"Run onboarding, paste tokens manually, or proceed with default?"*

## Design System Rules
Every diagram generated by this skill follows these non-negotiable constraints:
### Grid
- All coordinates, widths, gaps divisible by **4px** — prevents the AI-generated jitter
- No shadows anywhere
- Max border-radius: **10px**
- Borders: **1px hairline** only
### Typography (three families, three roles)
```
Instrument Serif → titles, italic editorial callouts
Geist Sans → node names, labels (primary UI text)
Geist Mono → technical sublabels (ports, URLs, field types, IDs)
```
Mono is for technical content specifically — not a blanket "dev aesthetic."
### Color discipline
- **One accent color** per diagram
- Accent reserved for **1–2 focal nodes** — the things the reader looks at first
- Everything else: `ink`, `muted`, `paper-2`
- Target visual density: **4/10** — ruthlessly sparse
### Focal nodes (coral tint)
```html
<!-- Accent node — use sparingly, 1–2 per diagram -->
<rect width="160" height="48" rx="6" fill="var(--accent)"/>
<text fill="var(--accent-fg)" font-family="Geist, sans-serif" font-size="13">
Primary Component
</text>
<!-- Standard node -->
<rect width="160" height="48" rx="6" fill="var(--paper-2)" stroke="var(--ink)" stroke-width="1"/>
<text fill="var(--ink)" font-family="Geist, sans-serif" font-size="13">
Secondary Component
</text>
```
