✅ GOOD: "Create a workflow that monitors an RSS feed for articles containing 'AI automation', 
   summarizes them using Claude, and posts the summary to Slack with the original link. 
   Run every 30 minutes. Include error handling for RSS fetch failures."

❌ POOR: "Make a workflow for RSS"

✅ GOOD: "Build a customer onboarding workflow: Trigger when new user signs up in Stripe, 
   create a Trello card with their details, send welcome email via SendGrid with personalized 
   content based on their plan tier, and add them to appropriate Mailchimp segment. 
   Handle cases where email bounces."

❌ POOR: "Customer workflow"

// Step-by-step refinement approach
const refinementProcess = {
  step1: "Initial build - Claude creates basic structure",
  step2: "Add credentials - 'Connect the Slack node to my workspace credentials'",
  step3: "Add logic - 'Add a filter to only process orders over $100'",
  step4: "Add error handling - 'Include retry logic for the API call'",
  step5: "Add notifications - 'Send me a summary email of what happened'",
  step6: "Schedule - 'Run this every day at 8 AM UTC'",
  step7: "Test and validate - 'Show me test data for this workflow'"
};

## Pre-Production Checklist

### Security
- [ ] Credentials are properly configured (not hardcoded)
- [ ] API keys are stored in n8n credential store
- [ ] Sensitive data is masked in logs
- [ ] Webhook endpoints use authentication

### Error Handling
- [ ] All API calls have retry logic
- [ ] Timeout configurations are set appropriately
- [ ] Error notifications are configured
- [ ] Fallback paths exist for critical failures

### Data Flow
- [ ] Input validation is present
- [ ] Data transformations are correct
- [ ] No infinite loops possible
- [ ] Memory usage is optimized (no large datasets in memory)

### Monitoring
- [ ] Workflow execution logging is enabled
- [ ] Success/failure metrics are trackable
- [ ] Alert thresholds are configured
- [ ] Run history retention is appropriate

### Documentation
- [ ] Workflow has descriptive name and description
- [ ] Complex nodes have comments
- [ ] Credential requirements are documented
- [ ] Business logic is explained

// Pitfall 1: Hardcoded credentials
// ❌ BAD: Claude might generate this
const badConfig = {
  apiKey: "sk-abc123xyz", // NEVER do this
  password: "supersecret"
};

// ✅ GOOD: Use n8n credentials
const goodConfig = {
  credentials: "my-api-service" // Reference credential by name
};

// Pitfall 2: Missing error handling
// ❌ BAD: No error path
const badWorkflow = {
  nodes: ["trigger", "apiCall", "notification"]
  // What happens if apiCall fails?
};

// ✅ GOOD: Every API call has error handling
const goodWorkflow = {
  nodes: [
    "trigger",
    { name: "apiCall", errorOutput: "errorHandler" },
    "notification",
    { name: "errorHandler", type: "slack", channel: "#errors" }
  ]
};

// Pitfall 3: Inefficient data handling
// ❌ BAD: Processing everything in memory
const badApproach = {
  getAllData: "{{ get10000Records }}", // Don't load 10k records
  process: "{{ transformAll }}"         // in one go
};

// ✅ GOOD: Batch processing
const goodApproach = {
  loop: {
    batchSize: 100,
    process: "{{ transformBatch }}",
    continueOnFail: true
  }
};

// Step 1: Export existing workflow
const existingWorkflow = await n8n.workflows.get(workflowId);

// Step 2: Describe improvements to Claude
const improvementPrompt = `
  I have this existing n8n workflow that processes orders.
  Current structure: ${JSON.stringify(existingWorkflow, null, 2)}
  
  Please rebuild it with these improvements:
  1. Add error handling to all API calls
  2. Implement parallel processing for independent operations
  3. Add data validation before database writes
  4. Include comprehensive logging
  5. Optimize for batch processing (current version processes one at a time)
`;

// Step 3: Claude returns improved version
const improvedWorkflow = await claude.buildWorkflow(improvementPrompt);

// Step 4: Test side-by-side
await testRunner.compare(existingWorkflow, improvedWorkflow);

// Step 5: Gradual rollout
await deployment.gradualRollout({
  newWorkflow: improvedWorkflow,
  trafficSplit: "10% initially, scale based on success rate"
});
