AI-powered debugging

When an error occurs, Claude can analyze the full context - stack trace, request parameters, user session, and recent code changes - to help you understand and fix it.

  • Analyze stack traces and identify root cause
  • Suggest code fixes with full context
  • Find similar past errors and their solutions

user: What's causing the NoMethodError in orders#create?

claude: Looking at error #4521...

The error occurs because `current_user.cart` returns nil when the user's session expires mid-checkout.

Fix: Add a nil check or redirect expired sessions:

- current_user.cart.items
+ current_user&.cart&.items || []
