Three parallel reviewer agents find contradictions, config gaps, and coverage holes across a project's docs, config, and tests — then fix what you approve. Heavyweight (dispatches parallel agents, can modify files). Supports env-var automation hooks (ADVERSARIAL_REVIEW_TARGETS, ADVERSARIAL_REVIEW_REPORT_ONLY) so an orchestrator can dispatch a programmatic validator pass without keyboard. Use only when explicitly asked: /adversarial-review, "adversarial review", "find gaps in my docs/config", OR when another skill (e.g. /feature) needs to dispatch a validator pass programmatically.
