Tasks get a thumbs up in planning. Work starts. Someone discovers there are no real acceptance criteria, or the scope is three tasks pretending to be one, or the dependency on another team was never mapped. Some of it ships anyway — and the defect report lands weeks later, with a root cause analysis that points straight back to the task.

Vindex reads each task the way a sharp reviewer would — checking whether it’s actually independent, valuable, estimable, small, testable, and negotiable — and tells you, in plain language, what’s missing. That’s it. It doesn’t replace planning. It makes planning catch what it currently misses.
