Agent Skills: adversarial-review

Use when dispatching a subagent to re-check work against external feedback (PR review comments, audit findings, multi-comment review cycles, 'did I really address X' verifications). Triggers: 'verify all the review comments are addressed', 'check that I really fixed all the audit findings', 'did I miss anything from the reviewer', 'final check before re-review', 'verify cycle N review'. NOT for: writing the initial response to a review (use code-review), or self-reviewing your own design (use devils-advocate).
