DEVELOPER
Bring on the slop.
Not built yet
A comment restating every line. Defensive null checks nobody asked for. A description longer than the diff. The same tells, in code.
Unslop Your PR will cut it down to the change a reviewer actually has to read. It is not built yet, and it is a different problem from everything above.
Cut the narration
A comment that restates the line below it is noise. So is a description that retells the diff.
Keep the change
Behaviour is the fact here. Nothing it removes may alter what the code does.
