Split one artifact across independent lenses and return where they converge and where they don't.

Goal

The result is a picture of where the lenses agree, where they disagree, and the smallest question that would resolve the disagreement. Not a checklist, and never an average — averaging the lenses is the failure this skill exists to prevent.

Workflow

1. Read the artifact end to end before choosing the lenses.
2. Choose one lens per genuinely distinct failure mode — correctness, security, readability, cost, adversarial-user, and the like. Two candidate lenses that share a failure mode are one lens, not two. In practice this lands between 2 and 5: below 2 there is nothing to converge, and past 5 you are almost always padding with lenses that overlap. There is no default count — the artifact's distinct failure modes set it.
3. Through each lens, produce a one-line verdict — pass, fail, or unclear — with its single most load-bearing reason. No hedging list; if a reason isn't load-bearing, drop it.
4. Compare the verdicts and group them: full agreement, agreement for different reasons, disagreement.
5. Where there is disagreement, name the single next question whose answer would move it into agreement or a clean split with owners. That question is the output, not the individual verdicts.
6. Where every lens agrees, return the shared verdict with the reasons that were load-bearing for at least two lenses.
