Doubt-Driven Review — Adversarial pre-mortem gate for risky diffs, migrations, and 'this is safe' claims

Qué hace

A single self-contained methodology skill: state the claim, extract artifact+contract, run an adversarial 'find what's wrong' review (fresh subagent, external CLI with approval, or labeled degraded self-review), classify every finding, and stop only on a defined exit condition. Triggers before production, auth, data, billing, or irreversible changes are allowed to stand as 'safe' or 'done'.

Informe de la prueba

Ran a real prod-column-drop scenario baseline-vs-skill: baseline gave a decent ad-hoc safety checklist, the skill forced an explicit CLAIM/CONTRACT/adversarial-findings structure that surfaced a missing-backup gap and a lock-contention-under-load edge case the baseline only hinted at, and ended in an auditable 'revise, don't approve yet' decision instead of a soft 'looks fine if...'.
