Ask the user to: + - Briefly describe the app this design system will serve (domain, platform, audience). + - Attach or reference the primary **design-system-style screenshot**. +2. Verify the screenshot quality: + - Flat (no heavy perspective). + - Includes multiple components (buttons, inputs, cards, nav patterns, typography). +3. Summarize back the intended style and constraints (e.g., brand adjectives, tone) before proceeding. + +### Phase 2: Create High-Level Style Guide (`design/design.json`) + +1. Explain to the user that you will create `design/design.json` as a high-level style guide. +2. Using the best available **vision model**, deeply analyze the reference screenshot and generate `design/design.json` with: + - Brand essence and key adjectives. + - Color palette (primary, secondary, accents, neutrals, states). + - Typography (families, weights, scales, usage rules). + - Layout and spacing rules (grid, spacing scale, padding patterns). + - Component-level guidelines (buttons, inputs, cards, navigation, alerts, tables, etc.). + - Design principles, do's and don'ts. +3. Save or propose the JSON content to be written to `design/design.json` at the project root. +4. Show a short summary of the generated guide and ask the user to confirm or request edits. Apply any requested tweaks. + +### Phase 3: Build the Showcase Application + +1. Confirm with the user: + - Where to place the showcase app (e.g., `design/showcase-app/`). + - That using React + Vite + Tailwind 3 is acceptable. +2. Use the best available **coding model** to scaffold a small Vite + React app that: + - Lives under the agreed folder (for example `design/showcase-app/`). + - Uses Tailwind CSS v3 configured consistently with `design/design.json`. +3. Implement a single screen (or small set of screens) that showcases all core components: + - Buttons (primary/secondary/tertiary, states). + - Form controls (inputs, selects, textareas). + - Cards, surfaces, and list items. + - Navigation (top bar/side bar as appropriate). + - Status components (badges, alerts, toasts). +4. Provide clear instructions to the user for running the app locally (e.g., `npm install`, `npm run dev` in the showcase folder) but never run commands or install dependencies without explicit confirmation. +5. Ask the user to visually review the running app and request specific adjustments (e.g., spacing, radii, shadows, color tweaks). Apply changes iteratively until the look closely matches the reference. + +### Phase 4: Codify the System (`design/design-system.json`) + +1. Once the showcase app feels correct, explain that you will codify the final system into `design/design-system.json`. +2. Analyze the actual implemented components and Tailwind classes in the showcase app and synthesize a comprehensive JSON file that includes: + - Exact Tailwind utility recipes for each component variant. + - Token-level spacing, radii, shadows, and typography scales. + - State rules (hover, focus, active, disabled, error, success, etc.). + - Motion/interaction patterns if present. + - High-level guidelines and do's/don'ts for when to use each component. +3. Propose the full JSON for `design/design-system.json` and write it to `design/design-system.json` once the user approves. +4.

Avoid generic fonts like Arial and Inter; opt instead for distinctive choices that elevate the frontend's aesthetics; unexpected, characterful font choices. Pair a distinctive display font with a refined body font. +- **Color & Theme**: Commit to a cohesive aesthetic. Use CSS variables for consistency. Dominant colors with sharp accents outperform timid, evenly-distributed palettes. +- **Motion**: Use animations for effects and micro-interactions. Prioritize CSS-only solutions for HTML. Use Motion library for React when available. Focus on high-impact moments: one well-orchestrated page load with staggered reveals (animation-delay) creates more delight than scattered micro-interactions. Use scroll-triggering and hover states that surprise. +- **Spatial Composition**: Unexpected layouts. Asymmetry. Overlap. Diagonal flow. Grid-breaking elements. Generous negative space OR controlled density. +- **Backgrounds & Visual Details**: Create atmosphere and depth rather than defaulting to solid colors. Add contextual effects and textures that match the overall aesthetic. Apply creative forms like gradient meshes, noise textures, geometric patterns, layered transparencies, dramatic shadows, decorative borders, custom cursors, and grain overlays. + +NEVER use generic AI-generated aesthetics like overused font families (Inter, Roboto, Arial, system fonts), cliched color schemes (particularly purple gradients on white backgrounds), predictable layouts and component patterns, and cookie-cutter design that lacks context-specific character. + +Interpret creatively and make unexpected choices that feel genuinely designed for the context. No design should be the same. Vary between light and dark themes, different fonts, different aesthetics. NEVER converge on common choices (Space Grotesk, for example) across generations. + +**IMPORTANT**: Match implementation complexity to the aesthetic vision. Maximalist designs need elaborate code with extensive animations and effects. Minimalist or refined designs need restraint, precision, and careful attention to spacing, typography, and subtle details. Elegance comes from executing the vision well. + +Remember: Claude is capable of extraordinary creative work.

How to Use the Result + +- **In AI coding tools:** Always include `@design/design-system.json` (and optionally `@design/design.json`) when asking an AI assistant to build new features or screens so

(visible in UI) +- **SECRET**: Encrypted value (hidden in UI, secure) + +--- + +## Deployment Phases + +Apps go through these phases during deployment: + +1. **PENDING_BUILD** - Queued for build +2. **BUILDING** - Building Docker image +3. **PENDING_DEPLOY** - Build complete, queued for deploy +4. **DEPLOYING** - Deploying to infrastructure +5. **ACTIVE** - Deployed and running βœ… +6. **ERROR** - Deployment failed ❌ +7. **CANCELED** - Deployment canceled ⚠️ + +--- + +## Examples + +### Example 1: Deploy with custom environment + +```bash +# Node.js +export DIGITALOCEAN_TOKEN="dop_v1_..." +export APP_ENV="staging" +node scripts/deploy-to-digitalocean.js + +# Python +DIGITALOCEAN_TOKEN="dop_v1_..." \ +APP_ENV="staging" \ +python scripts/deploy-to-digitalocean.py + +# Shell +DIGITALOCEAN_TOKEN="dop_v1_..." \ +./scripts/deploy-to-digitalocean.sh +``` + +### Example 2: Update single env var + +```javascript +// Node.js +import { updateEnvironmentVariables } from './scripts/deploy-to-digitalocean.js'; + +await updateEnvironmentVariables('app-id-123', { + FEATURE_ENABLED: 'true', + MAX_CONNECTIONS: '1000' +}); +``` + +```python +# Python +from

Example 3: Deploy specific branch + +Modify the spec in the script: +```javascript +const appSpec = { + // ... + services: [{ + github: { + repo: 'dundas/agentdispatch', + branch: 'develop', // Changed from 'main' + deploy_on_push: true + }, + // ... + }] +}; +``` + +### Example 4: Blue-green deployment + +```javascript +// Create new app with different name +const greenSpec = { + name: 'admp-server-green', // New instance + // ... same config as blue +}; + +const greenApp = await createApp(greenSpec); +await waitForDeployment(greenApp.id, greenApp.active_deployment.id); + +// Test green deployment +// If successful, update DNS or load balancer to point to green +// Then delete blue instance +``` + +--- + +## Monitoring & Logs + +### View logs programmatically + +```bash +#

response +{"status":"healthy"} +``` + +--- + +## Troubleshooting + +### Common Issues + +1. **401 Unauthorized** + - Check token is valid: `doctl auth list` + - Token needs Read + Write scopes + - Re-create token if needed + +2. **GitHub not authenticated** + - Connect GitHub once via web UI + - Go to: https://cloud.digitalocean.com/apps/new + - Authorize Digital Ocean + +3. **Deployment stuck in BUILDING** + - Check logs: `doctl apps logs --type BUILD` + - Verify Dockerfile builds locally + - Check for Docker image size limits + +4. **Health check failing** + - Verify `/health` endpoint returns 200 + - Check `http_port` matches app port (8080) + - Increase `initial_delay_seconds` if app needs more time + +--- + +## Cost Monitoring + +```bash +# Using doctl +doctl apps tier list +doctl apps tier instance-size list + +# API +curl -H "Authorization: Bearer $TOKEN" \ + https://api.digitalocean.com/v2/apps/tiers +``` + +**Current pricing:** +- Basic (512MB): $5/month +- Professional (1GB): $12/month +- Professional (2GB): $24/month + +--- + +## Security Best Practices + +1. **Never commit tokens to git** + ```bash + # Use environment variables + export DIGITALOCEAN_TOKEN="..." + + # Or use .env file (git-ignored) + echo "DIGITALOCEAN_TOKEN=dop_v1_..." >> .env.local + ``` + +2. **Use SECRET type for sensitive env vars** + ```javascript + { + key: 'DATABASE_URL', + value: 'postgres://...', + type: 'SECRET' // Encrypted + } + ``` + +3. **Rotate tokens regularly** + - Create new token monthly + - Delete old tokens + +4. **Use GitHub Secrets for CI/CD** + - Never expose tokens in workflow files + - Use encrypted secrets only + +--- + +## Next Steps + +1. βœ… Choose your deployment method (Node.js/Python/Shell/GitHub Actions) +2. βœ… Get Digital Ocean API token +3. βœ… Connect GitHub (one-time via web UI) +4. βœ… Run deployment script +5. βœ… Monitor deployment status +6. βœ… Verify health endpoint +7. βœ… Set up auto-deploy with
