Build Domino-styled web applications matching the Domino Design System. Use when creating or styling Domino apps (Dash, Streamlit, Flask, FastAPI+HTML), generating UI components, reviewing UX, or when the user mentions "Domino app", "Domino UI", "Domino dashboard", or "Domino design system". Covers the full stack — FastAPI backend, Ant Design 5.x frontend via CDN, Domino theme tokens (colors, typography, spacing), chart styling with Highcharts, Domino API authentication, proxy-safe routing, UX writing, error handling, empty states, form design, table patterns, and layout best practices. Also use for UX reviews of existing Domino app screenshots.

What this skill does


# Domino UI Design System Skill

## Architecture

Domino apps use **FastAPI** (Python backend) + **Ant Design 5.x** (frontend via CDN, no build step). Avoid inline styles and JS — use statically referenced CSS/JS files. Output errors to stdout.

### CDN Setup

Include in HTML `<head>`:

```html
<script src="https://unpkg.com/react@18/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom@18/umd/react-dom.production.min.js"></script>
<script src="https://unpkg.com/[email protected]/dist/antd.min.js"></script>
<link href="https://unpkg.com/[email protected]/dist/reset.css" rel="stylesheet">
<script src="https://unpkg.com/[email protected]/dayjs.min.js"></script>
<link href="https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600;700&display=swap" rel="stylesheet">
<script src="https://code.highcharts.com/highcharts.js"></script>
```

Use `React.createElement()` (aliased as `h`) — no JSX, no build step:

```javascript
const { ConfigProvider, Button, Table, Modal, Select, Input, Form, Space, Card, Tag, Alert } = antd;
const { createElement: h, useState, useEffect } = React;
```

## Domino Theme

Wrap the app in `ConfigProvider` with this theme:

```javascript
const dominoTheme = {
  token: {
    colorPrimary: '#543FDE',          // Purple
    colorPrimaryHover: '#3B23D1',
    colorPrimaryActive: '#311EAE',
    colorText: '#2E2E38',
    colorTextSecondary: '#65657B',
    colorTextTertiary: '#8F8FA3',
    colorSuccess: '#28A464',
    colorWarning: '#CCB718',
    colorError: '#C20A29',
    colorInfo: '#0070CC',
    colorBgContainer: '#FFFFFF',
    colorBgLayout: '#FAFAFA',
    colorBorder: '#E0E0E0',
    fontFamily: 'Inter, Lato, Helvetica Neue, Helvetica, Arial, sans-serif',
    fontSize: 14,
    borderRadius: 4,
    borderRadiusLG: 8,
  },
  components: {
    Button: { primaryShadow: 'none', defaultShadow: 'none' },
    Table: { headerBg: '#FAFAFA', rowHoverBg: '#F5F5F5' },
  },
};
```

### Top Navigation Bar

Height: 44px, Background: `#2E2E38`, Text: `#FFFFFF`. Use the Domino logo (height 32px). Primary actions on right. Only add nav items with real destinations.

**Domino Logo:** Reference `assets/domino-logo.svg` from this skill's directory (e.g. `.claude/skills/domino-ui-design/assets/domino-logo.svg`). The SVG is white text on transparent background, designed for the dark nav bar.

### Charts (Highcharts)

```javascript
Highcharts.setOptions({
  colors: ['#543FDE', '#0070CC', '#28A464', '#CCB718', '#FF6543', '#E835A7', '#2EDCC4', '#A9734C'],
  chart: { style: { fontFamily: 'Inter, Lato, Helvetica Neue, Arial, sans-serif' } },
});
```

## Domino API Integration

### Authentication

Re-acquire the access token on **every** API call (it expires quickly):

```python
import requests, os

def get_auth_headers():
    token = requests.get('http://localhost:8899/access-token').text.strip()
    return {'Authorization': f'Bearer {token}'}
```

### API Base Paths

Two separate APIs with **different** base paths:

| API | Base Path | Example |
|-----|-----------|---------|
| Platform APIs (public-api.json) | `/api/` | `{DOMINO_API_HOST}/api/jobs/beta/jobs?projectId=...` |
| Legacy Platform APIs | `/v4/` | `{DOMINO_API_HOST}/v4/jobs?projectId=...` |
| Governance APIs | `/api/governance/v1/` | `{CLUSTER_URL}/api/governance/v1/bundles?project_id=...` |

**Do NOT** add `/api/` prefix to v4 platform endpoints.

### Environment Variables (available in Domino)

`DOMINO_API_HOST`, `DOMINO_PROJECT_ID`, `DOMINO_PROJECT_NAME`, `DOMINO_PROJECT_OWNER`

Do not add mock/fake data if the API isn't working. Prompt user to set env vars.

## Running the App

Use relative URLs (not absolute) — Domino's nginx proxy modifies the root URL.

```bash
#!/bin/bash
uvicorn app:app --host 0.0.0.0 --port 8888
```

## UX Design Rules

For detailed UX principles, writing guidelines, component patterns, and review checklists, read [references/ux-design-rules.md](references/ux-design-rules.md).

Key rules to always follow:
- **Empty states must be actionable** — answer: What is this? Why is it empty? What can I do?
- **Error messages must be human-readable** with guidance on what to do next
- **Disabled elements must explain why** they're disabled (tooltip)
- **Truncated table text must have tooltips**
- **Icon-only buttons must have tooltips**
- **Use sentence case** for UI text (not Title Case)
- **No exclamation points** in UI copy
- **Side panels should overlay**, not push/crush main content
- **Checkboxes should use positive framing** — checked = ON/enabled, never checked = OFF/disabled

## UX Review

When reviewing a Domino app UI, read [references/ux-design-rules.md](references/ux-design-rules.md) and check against the review checklists. Classify issues as High/Medium/Low severity.

## Documentation Reference

Before writing or verifying any API call, use the cluster swagger to confirm current endpoint paths and field names. Use public docs for workflow context and field explanations.

**Get the cluster base URL:** `$DOMINO_API_HOST` (injected by Domino into every workspace, job, and app).

This skill uses two swagger docs:

**Public API** (covers `/api/` endpoints — v1, v2, beta — no auth required):
```bash
curl "$DOMINO_API_HOST/assets/public-api.json"
# Browser UI: $DOMINO_API_HOST/assets/lib/swagger-ui/index.html?url=/assets/public-api.json#/
```

**Governance API** (covers `/api/governance/v1/` endpoints, requires bearer token):
```bash
TOKEN=$(curl -s http://localhost:8899/access-token)
# Governance is not routed through $DOMINO_API_HOST. Derive the external cluster URL
# from the JWT iss claim — works in any workspace type.
CLUSTER_URL=$(echo $TOKEN | cut -d'.' -f2 | python3 -c "
import sys, base64, json, re
p = sys.stdin.read().strip()
p += '=' * (-len(p) % 4)
print(re.sub(r'/auth/realms/.*', '', json.loads(base64.b64decode(p))['iss']))
")
curl -H "Authorization: Bearer $TOKEN" "$CLUSTER_URL/api/governance/swagger/doc.json"
# Browser UI (must be logged in): $CLUSTER_URL/api/governance/swagger/index.html
```

contribute

Included

Local-only OSS contribution command center. Auto-refreshes the user's in-flight PR and issue state on invoke so conversations start with full context — no need to brief Claude on what's in flight. Helps the user find issues to contribute to on GitHub, builds per-repo dossiers of what each upstream expects (CLA, DCO, branch convention, AI policy, draft-first, review bots, issue templates), runs deterministic gates before any external action so AI-assisted contributions don't reach maintainers as slop. State is markdown-only: candidate files at ~/.contribute-system/candidates/, repo dossiers at ~/.contribute-system/research/, append-only event log at ~/.contribute-system/log.jsonl. No database, no cloud calls. Use when the user asks about their PRs / issues / contributions, wants to find new work to take on, claim an issue, build/refresh a repo's dossier, or draft a Design Issue or PR. Trigger with "/contribute", "what's my PR status", "find a contribution", "claim issue X", "draft a Design Issue for Y", "refresh dossier for Z".

architectural-analysis

Included

User-triggered deep architectural analysis of a codebase or scoped subtree across eight modes — information architecture, data flow, integration points, UI surfaces, interaction patterns, data model, control flow, and failure modes. This skill should be used when the user asks to "diagram this codebase," "map the architecture," "show the data flow," "give me an ERD," "trace control flow," "find the integration points," "verify the layout pattern," "audit the UX architecture," or any similar request whose primary deliverable is mermaid diagrams plus cited reports under docs/architecture/. Dispatches haiku/sonnet sub-agents in parallel for per-mode exploration, then verifies every citation mechanically before any node lands in a diagram. Not for one-off prose explanations of code (use code-explanation) or for high-level system design from scratch (use system-design).
