A few days ago, someone left a comment on one of my open source projects.

They'd tried my CLI tool — a 3D print quality inspector called Printsight — and found it flagged false defects on prints with uneven lighting. They suggested adding CLAHE (a contrast equalization algorithm) as a preprocessing step.

Good suggestion. Practical. Specific. The kind of feedback you want.

But it took me a while to understand what they were really asking me.

They weren't asking me to add CLAHE. They were telling me: your tool doesn't work in my environment, and I want it to.
