AIE

Domain knowledge outlived every tool

— We changed tools four times in four months
— The financial domain knowledge improved results on every one of them

Structured as a composable prompt component:

— How to interpret margins, profitability, revenue cascades
— Model type recognition (DCF, LBO, three-statement)
— Communication conventions ($1.2M not $1,234,567.89)
— "Never calculate in your head what the spreadsheet can calculate for you"

It was the most reused component in the system.
