# Cursor AI workflow — refactor a legacy Python function

# 1. Open the file and highlight the function
# 2. Press Cmd+K (inline edit) or Cmd+L (chat)

# Prompt example:
"""
Refactor this function to:
- Use type hints throughout
- Replace the dict with a dataclass
- Add proper error handling for missing keys
- Add a docstring with examples
Keep the same external behavior.
"""

# Cursor reads the full file context and surrounding code
# Applies multi-line changes across the file
# Shows a diff for review before applying

# Result: 30-line legacy function → clean, typed, tested code
# Time: ~15 seconds vs ~10 minutes manual refactoring

# AI-powered automation example
trigger: New email in Gmail with subject containing "invoice"

steps:
  - ai_extract:
      prompt: "Extract vendor name, amount, due date from email body"
      output: { vendor, amount, due_date }

  - create_record:
      app: Airtable
      table: Invoices
      fields:
        vendor: "{{vendor}}"
        amount: "{{amount}}"
        due_date: "{{due_date}}"
        status: "pending"

  - send_slack:
      channel: "#finance"
      message: "New invoice from {{vendor}}: ${{amount}} due {{due_date}}"

# What used to take 5 minutes now happens automatically
