Deployment Audit Skill

Deployment Audit Skill

Purpose

Continuously monitor and troubleshoot deployments on DigitalOcean and Vercel for Synthex / Unite-Hub.

Typical Tasks

1. Retrieve crash logs via DO CLI / MCP
   • doctl apps list
   • doctl apps logs <app-id> --type=run_restarted
   • doctl apps logs <app-id> <component> --type=run_restarted
2. Check environment variable consistency across:
   • .env.local
   • Vercel project settings
   • DigitalOcean app spec
3. Validate:
   • Correct Supabase URLs and keys
   • Correct Stripe keys (test vs live)
   • Correct callback/​redirect URLs

Output

• Human-readable audit summary in docs/​audit/​DEPLOYMENT_HEALTH.md
• Issue entries in docs/​audit/​AUDIT_ISSUES_REGISTRY.json

Health Check Process

Step 1: Environment Sync

Compare variables across:

• Local .env.local
• Vercel environment variables
• DigitalOcean app spec

Flag mismatches.

Step 2: Build Verification

• Run npm run build
• Check for TypeScript errors
• Check for missing dependencies
• Verify all routes compile

Step 3: Runtime Validation

• Check recent deploy logs
• Look for crash patterns
• Identify memory/​CPU spikes
• Flag slow endpoints

Step 4: API Health

• Ping key API endpoints
• Verify authentication works
• Check database connectivity
• Validate external service connections

Common Issues & Fixes

Issue: "Module not found"

Cause: Missing dependency Fix: npm install <module>

Issue: "Invalid environment variable"

Cause: Variable not set or wrong format Fix: Check .env.local and deployment settings

Issue: "Memory limit exceeded"

Cause: Heavy computation or memory leak Fix: Optimize code, increase limit, or add caching

Issue: "Database connection timeout"

Cause: Too many connections or network issue Fix: Enable connection pooling, check Supabase status
