The ask

Sent verbatim as the prompt. The agent works in a copy of the workspace below and sees nothing else.

The owners want electricity by building for January to June, month by month. Build it as energy.xlsx with live formulas and put anything I should know in memo.md. Omar's email explains how the meter reads work.
