Detail
A general-purpose assistant writes Excel formulas that look right and quietly are not. The gap is not intelligence, it is standards: it does not know the 5G dynamic-array conventions, it does not know how a recursive LAMBDA should be structured, and it has no opinion about what makes a macro slow.
This repository packages that knowledge as skills — 5G LAMBDA authoring, VBA optimisation, and conversation transcript export. Each one encodes a way of working, so the output is consistent rather than improvised.
It is public, MIT-adjacent in spirit, and the most direct evidence on this site that the AI part of my work is practice rather than vocabulary.
