Mail Expenses — Financial Transaction Summary
Period: $ARGUMENTS (default: last 24 hours)
Step 1: Find financial emails
Use SQLite date functions — never compute Unix epochs manually (wrong year risk).
DB="$HOME/Library/Mail/V10/MailData/Envelope Index"
# Date range from $ARGUMENTS. Use SQLite date expressions directly:
# "yesterday" → dt >= date('now','-1 day','localtime') AND dt < date('now','localtime')
# "today" → dt >= date('now','localtime')
# "last 7 days" → dt >= date('now','-7 days','localtime')
# "this month" → dt >= date('now','start of month','localtime')
# Always print the range before querying so the period is visible in output.
sqlite3 "$DB" "
SELECT datetime(m.date_received,'unixepoch','localtime') as dt,
s.subject, a.address as sender, mb.url, m.ROWID
FROM messages m
JOIN subjects s ON m.subject = s.ROWID
JOIN addresses a ON m.sender = a.ROWID
JOIN mailboxes mb ON m.mailbox = mb.ROWID
WHERE datetime(m.date_received,'unixepoch','localtime') >= date('now','-1 day','localtime')
AND datetime(m.date_received,'unixepoch','localtime') < date('now','localtime')
AND m.deleted = 0
AND mb.url NOT LIKE '%Spam%' AND mb.url NOT LIKE '%Trash%'
AND mb.url NOT LIKE '%Sent%'
AND (

ORDER BY m.date_received DESC;" 2>/dev/nullStep 2: Parse amounts from email bodies
python3 ~/.claude/skills/_mail-shared/parser.py <ROWID1> <ROWID2> ...Step 3: Extract amounts with Python regex
From each parsed body, extract monetary amounts:
import re
patterns = [
r'(?:Rp|IDR)\s*[\d.,]+', # Indonesian Rupiah
r'(?:USD|US\$|\$)\s*[\d.,]+', # USD
r'(?:SGD|S\$)\s*[\d.,]+', # Singapore dollar
r'Total[:\s]+(?:Rp|IDR|USD|\$|€|£)[\d.,]+',
r'Amount[:\s]+(?:Rp|IDR|USD|\$|€|£)[\d.,]+',
r'(?:€|£|¥|₹|RM|THB|PHP|VND)\s*[\d.,]+',
]Step 4: Categorize transactions
- Transfers (bank to bank, BI-Fast, QRIS, virtual account)
- Bills/Subscriptions (recurring charges, renewals)
- Shopping (e-commerce, marketplace)
- Food/Lifestyle (restaurants, delivery, groceries)
- Travel (flights, hotels, transport)
- Refunds (money coming back)
- Credit Card Payments (paying off balances — not new spending)
