AI Boss Type
MFSLThe Old Doctor
Others ask AI for new features. You ask it to explain the old code.
Looks, listens, asks, then treats: one problem, understood all the way.
The four letters
M · MicroOpposite: H Hands-off
In at least 50% of your turns the AI checked back with you before 8 tool calls in a row, without a subagent.
F · FixOpposite: B Build
50% or less of your changed lines went into new files. Mostly, you patch what's already there.
S · SpecialistOpposite: G Generalist
The work stays in a narrow lane: fewer than 3 crew roles reach 10%.
L · LarkOpposite: O Owl
50% or less of your working minutes fall between 8 PM and 8 AM. Daylight does the heavy lifting.
Perfect match
Perfect match: first two letters flipped, last two the same.
