What they did

She put all her personal credit card statements in a folder and asked Claude Code to find business expenses to be reimbursed. First, the agent reviewed the first few statements with her, asked about doubtful cases, and only then classified the rest and generated the spreadsheet.

How it went

She got the spreadsheet of expenses to be reimbursed.

Good to know

Letting the AI learn from examples before classifying greatly reduces errors.

The prompt

Here are statements from [months]. Start with the first 2 and ask me about any doubtful entries so you can learn my criteria for business expenses. Then classify the rest and generate a spreadsheet with date, amount, merchant and category.

Replace what is in [brackets]. Prompt written by us from the account, not a literal copy of the source. Do not paste other people’s personal data (privacy laws such as LGPD and GDPR apply).

Summary in our own words. Results as stated in the original account; we have not tested or audited them. Read the source ↗ Case found via agentusecases.ai (Alex Finn); text and prompt rewritten by us. Found a mistake?
