- Worth noticing
- The site says assistants retrieve matching rows only, while totals are calculated in code rather than by the model.
Field notes
The illustrated setup has the assistant suggest table columns and confirm them before logging begins. For retrieval, the page shows filters such as date range, category, and note text, and says only matching rows are sent back. Its spending example displays six matched entries and a total; the site says calculations are performed in code rather than by the AI model.
