| description | Use this skill whenever Claude needs to identify business-related spending inside personal financial statements, build candidate transaction rows, or decide whether transactions are likely business, personal, or need review based on a local trading profile. |
Business Transaction Identifier
Required Context
Read .claude/skills/business-transaction-identifier/references/trading.MD first. If it is missing, ask the user to run /trading.
Use the profile to understand the business model, normal suppliers, likely expense categories, and transactions that should stay personal.
Inputs
- Raw statements from
statements/inbox/ or a user-supplied path.
- Supported target formats: PDF, CSV, XLS, XLSX, OFX, QIF, QFX, and other formats that local tools can extract.
Classification Process
- Create a source manifest for each statement: file path, file size, and SHA-256 hash.
- Parse deterministically where possible:
- CSV/TSV: use headers and column types rather than manual string splitting.
- XLS/XLSX/ODS: use spreadsheet readers where available.
- PDF: try text/table extraction first; document any OCR or manual row-boundary inference.
- Normalize transaction fields before classification.
- Classify each transaction as
business, needs_review, or personal.
- Keep only
business and needs_review candidates for verification.
Candidate Row Schema
Use these columns or JSON keys:
source_file,source_file_sha256,statement_row_id,transaction_date,posted_date,description,amount,currency,account_hint,category,business_reason,confidence,evidence,status
Decision Rules
- Business spend needs a concrete link to the trading profile.
- Treat tax, software, cloud, banking fees, professional services, equipment, travel for trading activity, and relevant subscriptions as likely business when the profile supports them.
- Treat groceries, entertainment, family, household, personal transfers, cash withdrawals, and ambiguous card payments as personal or
needs_review unless the evidence is strong.
- Never create a final CSV. Candidates must go through statement reconciliation first.
- Do not store raw statement contents in tracked files.
