Claude passes it on, Expense Agent does the math

Claude only passes along exactly what you said. The amount, date and category are worked out by fixed rules, not by how Claude reads it.

Reads amounts the way you write them

  • 4.50 → $4.50
  • $12 → $12.00
  • 1,200 → $1,200.00
  • 1,200.50 → $1,200.50
  • 20 EUR → $21.92
  • €20 → $21.92
  • $4.50 in a Canadian ledger → C$4.50
  • "12,50" → asks first

Teach it once, it remembers

Say "Starbucks is always Coffee". From then on, it's sorted for you.
