Dispatch an independent challenger agent to adversarially review a spec or implementation plan against the actual codebase. Catches hallucinated APIs, wrong field names, nonexistent files, and incorrect assumptions. Two modes: (1) spec review — verifies DB model fields, API paths, config attributes, file paths referenced in a design spec, (2) plan review — verifies imports, function signatures, constructor args, file paths in an implementation plan. Use after brainstorming produces a spec, or after writing-plans produces a plan, before execution. Triggers: "review the spec", "review the plan", "challenge this", "check for hallucinations", "design review", "spec review", "plan review", "/design-review".
