What they did
One skill searches Gmail for tax documents, downloads attachments, extracts amounts and lists what's missing. Another compiles donations, receipts and credit card statements into spreadsheets ready for the tax filing software, and it also built the schedule for his consulting income. He personally reviewed the statements for medical and childcare expenses.
How it went
The blog describes the workflow running, with human review on the sensitive parts.
