Self-Healing System

When browser automation fails due to DoorDash UI changes:

1. Capture State - Takes ARIA snapshot + screenshot
2. Claude Analysis - Asks Claude API to find the new element
3. Update Patterns - Stores new working selectors
4. Retry Operation - Continues with updated patterns
5. Log Event - Records healing for review

Pattern Structure

{
  "add_to_cart_button": {
    "description": "Button to add menu item to cart",
    "version": 3,
    "strategies": [
      {
        "type": "aria_role",
        "role": "button",
        "textContains": "Add to Order",
        "priority": 1
      }
    ],
    "healingHistory": [...]
  }
}

Safety Guardrails

1. Order Confirmation Required - Never places order without explicit "confirm" or "yes"
2. Order Review - Always shows full summary before confirming
3. Rate Limiting - Max 3 healing attempts per pattern per hour
4. Error Logging - All errors logged to Craft
5. Auto-Save - State saved every 5 minutes
6. Test Mode - Set TEST_MODE=true to prevent real orders

Example Usage

# Set delivery address
> set_location address="123 Main St, Denver, CO 80202"

# Browse restaurants

Troubleshooting

Authentication Failed

• Check credentials in .env
• DoorDash may require 2FA - check email

Pattern Healing Failing

• Check Craft error log for details
• Pattern may need manual update
• Verify Claude API key is valid

Browser Automation Issues

• Shopping & Travel MCP must be running
• Check browser session state
• Try clearing session and re-authenticating
