BREAKING CHANGE: Removed FEATURE_CHANGELOG.md and test-reports/ **What changed:** - All 6 agents now use Git commands to check existing features/components - Feature specs include test results and deployment status (no separate files) - Git commits are the single source of truth for implementation details - Git tags for deployment versioning (e.g., v1.0.0-PROJ-1) **Why:** - Prevents context bloat (no growing FEATURE_CHANGELOG.md) - Scales better (Git is built for large projects) - No manual changelog maintenance - Better developer experience (native Git workflow) **Migration:** - Requirements Engineer: Uses `ls features/` and `git ls-files` instead of FEATURE_CHANGELOG - Solution Architect: Uses `git ls-files src/components/` to check existing code - Frontend/Backend Devs: Use `git log --grep="PROJ-X"` to see feature history - QA Engineer: Adds test results directly to feature spec - DevOps: Updates feature spec with deployment status + creates Git tags **Files changed:** - Updated all 6 agent instructions (.claude/agents/*.md) - Deleted FEATURE_CHANGELOG.md - Deleted test-reports/ folder - Updated PROJECT_CONTEXT.md (removed references) - Updated README.md (v1.4.0, updated workflow) - Updated features/README.md (new format with QA + Deployment sections) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

|
||
- [x] All features working
|
||
- [x] No errors in Vercel Logs
|
||
- [x] Database connections working
|
||
- [x] Auth flows working
|
||
|
||
## Rollback Plan
|
||
If issues occur:
|
||
1. Revert to previous deployment (Vercel Dashboard → Deployments → Rollback)
|
||
2. Check Vercel Logs for error details
|
||
3. Fix issues locally
|
||
4. Redeploy
|
||
```
|
||
|
||
### Environment Variables Setup
|
||
```bash
|
||
# In Vercel Dashboard → Settings → Environment Variables
|
||
|
||
# Supabase
|
||
NEXT_PUBLIC_SUPABASE_URL=https://xyz.supabase.co
|
||
NEXT_PUBLIC_SUPABASE_ANON_KEY=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...
|
||
|
||
# Add more as needed
|
||
# STRIPE_SECRET_KEY=sk_live_...
|
||
# SMTP_HOST=smtp.sendgrid.net
|
||
```
|
||
|
||
## Common Issues
|
||
|
||
### Issue 1: Build Fails on Vercel
|
||
**Symptom:** Build succeeds locally but fails on Vercel
|
||
**Solution:**
|
||
1. Check Node.js version (Vercel uses specific version)
|
||
2. Check package.json dependencies
|
||
3. Check Vercel Build Logs for error details
|
||
|
||
### Issue 2: Environment Variables nicht verfügbar
|
||
**Symptom:** App deployed, aber DB Connection fails
|
||
**Solution:**
|
||
1. Check Vercel → Settings → Environment Variables
|
||
2. Ensure NEXT_PUBLIC_ prefix for client-side vars
|
||
3. Redeploy (Environment Variable changes require redeploy)
|
||
|
||
### Issue 3: Database Connection Error
|
||
**Symptom:** App deployed, aber Supabase Queries fail
|
||
**Solution:**
|
||
1. Check Supabase Dashboard → Project Settings → API
|
||
2. Verify URL and Keys are correct
|
||
3. Check Row Level Security (RLS) policies
|
||
|
||
## Best Practices
|
||
- **Never commit secrets:** Use Environment Variables
|
||
- **Test before deploy:** Always test locally first
|
||
- **Monitor logs:** Check Vercel Logs after deploy
|
||
- **Rollback ready:** Know how to rollback quickly
|
||
- **Document:** Keep Environment Variables documented
|
||
|
||
## Human-in-the-Loop Checkpoints
|
||
- ✅ Before Deploy → User approved Production-readiness
|
||
- ✅ After Deploy → User tested Production URL
|
||
- ✅ Bei Errors → User entscheidet: Fix oder Rollback
|
||
|
||
## Wichtig
|
||
- **Niemals direkt in Production testen**
|
||
- **Immer** Backup-Plan haben (Rollback)
|
||
- **Dokumentiere** jeden Deploy (Git Commit Message)
|
||
|
||
## Checklist vor Deployment

- [ ] **Feature-Spec updated:** Status auf ✅ Deployed gesetzt in `/features/PROJ-X.md`
|
||
- [ ] **Git Tag erstellt:** Version Tag für Deployment (z.B. `v1.0.0-PROJ-X`)
|
||
|
||
Erst wenn ALLE Checkboxen ✅ sind → Deployment ist erfolgreich abgeschlossen!
|
||
|
||
## ⚠️ WICHTIG: Git als Single Source of Truth!
|
||
|
||
**Nach jedem erfolgreichen Deployment:**
|
||
|
||
1. **Feature Spec updaten:**
|
||
```bash
|
||
# Öffne /features/PROJ-X.md und setze Status:
|
||
Status: ✅ Deployed (2026-XX-XX)
|
||
Production URL: https://your-app.vercel.app
|
||
```
|
||
|
||
2. **Git Tag erstellen (optional aber empfohlen):**
|
||
```bash
|
||
git tag -a v1.0.0-PROJ-X -m "Deploy PROJ-X: Feature Name to production"
|
||
git push origin v1.0.0-PROJ-X
|
||
```
|
||
|
||
3. **Deployment Commit:**
|
||
```bash
|
||
git add features/PROJ-X.md
|
||
git commit -m "deploy(PROJ-X): Deploy Feature Name to production
|
||
|
||
- Production URL: https://your-app.vercel.app
|
||
- Deployed: 2026-XX-XX
|
||
- Status: ✅ All tests passed
|
||
"
|
||
git push
|
||
```
|
||
|
||
**Warum Git Tags?**
|
||
- Schnelles Rollback: `git checkout v1.0.0-PROJ-2`
|
||
- Deployment History: `git tag -l`
|
||
- Einfache Versionierung
|
||
|
||
## Rollback Instructions (for emergencies)
|
||
|
||
Falls Production fehlschlägt:
|
||
|
||
1. **Sofortiges Rollback in Vercel:**
|
||
- Gehe zu Vercel Dashboard → Deployments
|
||
- Finde die letzte funktionierende Version
|
||
- Click "Promote to Production"
|
||
- Fertig (< 1 Minute)
|
||
|
||
2. **Fix lokal + Redeploy:**
|
||
- Fix den Bug lokal
|
||
- `npm run build` (prüfe dass es funktioniert)
|
||
- Commit + Push
|
||
- Vercel deployed automatisch
|
||
|
||
**Niemals in Panik geraten – Rollback ist immer möglich!**

## Production-Ready Essentials
|
||
|
||
### 1. Error Tracking Setup (Sentry)
|
||
|
||
**Warum?** Produktions-Errors automatisch erfassen und benachrichtigt werden.
|
||
|
||
**Setup in 5 Minuten:**
|
||
|
||
1. **Sentry Account erstellen:** https://sentry.io (kostenlos für kleine Apps)
|
||
|
||
2. **Next.js Integration:**
|
||
```bash
|
||
npx @sentry/wizard@latest -i nextjs
|
||
```
|
||
|
||
3. **Environment Variables in Vercel:**
|
||
```bash
|
||
SENTRY_DSN=https://xxx@sentry.io/xxx
|
||
NEXT_PUBLIC_SENTRY_DSN=https://xxx@sentry.io/xxx
|
||
```
|
||
|
||
4. **Verify:** Trigger einen Test-Error, prüfe Sentry Dashboard
|
||
|
||
**Alternative:** Vercel Error Tracking (built-in, aber weniger Features)
|
||
|
||
---
|
||
|
||
### 2. Security Headers (Next.js Config)
|
||
|
||
**Warum?** Schützt vor XSS, Clickjacking, und anderen Attacks.
|
||
|
||
**Setup:**
|
||
|
||
Erstelle/update `next.config.js`:
|
||
|
||
```javascript
|
||
/** @type {import('next').NextConfig} */
|
||
const nextConfig = {
|
||
async headers() {
|
||
return [
|
||
{
|
||
source: '/:path*',
|
||
headers: [
|
||
{
|
||
key: 'X-Frame-Options',
|
||
value: 'DENY', // Verhindert Clickjacking
|
||
},
|
||
{
|
||
key: 'X-Content-Type-Options',
|
||
value: 'nosniff', // Verhindert MIME-Type Sniffing
|
||
},
|
||
{
|
||
key: 'Referrer-Policy',
|
||
value: 'origin-when-cross-origin',
|
||
},
|
||
{
|
||
key: 'Strict-Transport-Security',
|
||
value: 'max-age=31536000; includeSubDomains', // HSTS
|
||
},
|
||
],
|
||
},
|
||
]
|
||
},
|
||
}
|
||
|
||
module.exports = nextConfig
|
||
```
|
||
|
||
**Verify:** Nach Deployment → Chrome DevTools → Network Tab → Headers prüfen
|
||
|
||
**Optional (Advanced):** Content-Security-Policy (CSP) – aber vorsichtig, kann App brechen!
|
||
|
||

|
||
|
||
### 3. Environment Variables Best Practices
|
||
|
||
**Wichtig:** Secrets Management!
|
||
|
||
#### ✅ DO:
|
||
- **Niemals** Secrets in Git committen
|
||
- `.env.local` zu `.gitignore` hinzufügen (ist default)
|
||
- Erstelle `.env.local.example` mit Dummy-Values:
|
||
```bash
|
||
# .env.local.example
|
||
NEXT_PUBLIC_SUPABASE_URL=your_supabase_url_here
|
||
NEXT_PUBLIC_SUPABASE_ANON_KEY=your_anon_key_here
|
||
SENTRY_DSN=your_sentry_dsn_here
|
||
```
|
||
|
||
#### ❌ DON'T:
|
||
- Niemals API Keys in Client-Side Code hardcoden
|
||
- `NEXT_PUBLIC_` nur für wirklich öffentliche Werte (werden im Browser sichtbar!)
|
||
- Keine Secrets in Vercel Preview Deployments (use Production-only vars)
|
||
|
||
#### Vercel Environment Variables:
|
||
- **Production:** Sensible Keys (Stripe Live Key, etc.)
|
||
- **Preview:** Test Keys (Stripe Test Key, etc.)
|
||
- **Development:** Local `.env.local`
|
||
|
||

|
||
|
||
### 4. Performance Monitoring (Lighthouse)
|
||
|
||
**Warum?** Slow Apps = User verlassen die Seite.
|
||
|
||
**Quick Check (nach jedem Deployment):**
|
||
|
||
1. Öffne Chrome DevTools
|
||
2. Lighthouse Tab
|
||
3. "Generate Report" (Mobile + Desktop)
|
||
4. **Ziel:** Score > 90 in allen Kategorien
|
||
|
||
**Häufige Performance-Killer:**
|
||
- ❌ Unoptimierte Images (nutze `next/image`)
|
||
- ❌ Zu großes JavaScript Bundle (nutze Dynamic Imports)
|
||
- ❌ Slow API Calls (add Loading States)
|
||
- ❌ Keine Caching Strategy
|
||
|
||
**Fix:**
|
||
```typescript
|
||
// Before (❌ Slow)
|
||
<img src="/large-image.jpg" />
|
||
|
||
// After (✅ Fast)
|
||
import Image from 'next/image'
|
||
<Image src="/large-image.jpg" width={800} height={600} alt="..." />
|
||
```
|
||
|
||
**Automated Monitoring:** Vercel Analytics (automatic in Pro Plan)
|
||
|
||
---
|
||
|
||
## Quick Reference: Production-Ready Checklist
|
||
|
||
Vor dem ersten Production Deployment:
|
||
|
||
- [ ] **Error Tracking:** Sentry/Vercel Error Tracking aktiviert
|
||
- [ ] **Security Headers:** `next.config.js` mit Security Headers
|
||
- [ ] **Environment Variables:** `.env.local.example` dokumentiert, Secrets nur in Vercel
|
||
- [ ] **Performance:** Lighthouse Score > 90 (alle Kategorien)
|
||
- [ ] **Images:** Alle Images nutzen `next/image`
|
||
- [ ] **Loading States:** Alle API Calls haben Loading/Error States
