Finance Skill

Personal finance memory layer. Parse statements, store transactions, query spending.

Data Location

  • Transactions: ~/.openclaw/workspace/finance/transactions.json

  • Raw statements: ~/.openclaw/workspace/finance/statements/

Storage convention: OpenClaw workspace (~/.openclaw/workspace/) is the standard location for persistent user data. This matches where session-memory and other hooks store agent data. Credentials/config would go in ~/.config/finance/ if needed.

Tools

1. Parse Statement

When user shares a statement (image or PDF):

⚠️ IMPORTANT: Telegram/channel previews truncate PDFs! Always extract with pypdf first to get ALL pages:

python3 -c "
import pypdf
reader = pypdf.PdfReader('/path/to/statement.pdf')
for i, page in enumerate(reader.pages):
    print(f'=== PAGE {i+1} ===')
    print(page.extract_text())
"

Then parse the full text output:

  1. Extract transactions from ALL pages

  2. Return JSON array: [{date, merchant, amount, category}, ...]

  3. Run scripts/add-transactions.sh to append to store

  4. Verify total matches statement (sum of expenses should equal "Total purchases")

Extraction format:

Each transaction: {"date": "YYYY-MM-DD", "merchant": "name", "amount": -XX.XX, "category": "food|transport|shopping|bills|entertainment|health|travel|other"}
Negative = expense, positive = income/refund.

Categories:

  • food: restaurants, groceries, coffee, fast food

  • transport: Waymo, Uber, gas, public transit

  • shopping: retail, online purchases

  • bills: utilities, subscriptions

  • entertainment: movies, concerts, theme parks

  • health: pharmacy, doctors

  • travel: hotels, flights

2. Query Transactions

User asks about spending → read transactions.json → filter/aggregate → answer

Example queries:

  • "How much did I spend last month?" → sum all negative amounts in date range

  • "What did I spend on food?" → filter by category

  • "Show my biggest expenses" → sort by amount

3. Add Manual Transaction

User says "I spent $X at Y" → append to transactions.json

File Format

{
  "transactions": [
    {
      "id": "uuid",
      "date": "2026-02-01",
      "merchant": "Whole Foods",
      "amount": -87.32,
      "category": "food",
      "source": "statement-2026-01.pdf",
      "added": "2026-02-09T19:48:00Z"
    }
  ],
  "accounts": [
    {
      "id": "uuid",
      "name": "Coinbase Card",
      "type": "credit",
      "lastUpdated": "2026-02-09T19:48:00Z"
    }
  ]
}

Usage Flow

  1. User: shares statement image

  2. Agent: extracts transactions via vision, confirms count

  3. Agent: runs add script to store

  4. User: "how much did I spend on food?"

  5. Agent: reads store, filters, answers

Dependencies

  • jq — for JSON transaction storage and querying (apt install jq / brew install jq)

  • pypdf — for full PDF text extraction (pip3 install pypdf)

Lessons Learned

  • Telegram truncates PDF previews — always use pypdf to get all pages

  • Verify totals — sum extracted expenses and compare to statement total before importing

  • Coinbase Card — no Plaid support, statement upload only

Future: Plaid Integration

  • Add finance_connect tool for Plaid OAuth flow

  • Auto-sync transactions from connected banks

  • Same query interface, different data source
