Plan Review Skill

Adversarial review gate for plan-mode drafts: the plan is challenged by an independent reviewer and revised until convergence before ExitPlanMode presents it to the user.

Trigger

• Keywords: plan review, review plan, plan-review, pre-ExitPlanMode review
• Self-invoke: in plan mode, before calling ExitPlanMode, when the project opts in via auto-loop-project.md ## Plan Review: enabled or the user asks for plan review

When NOT to Use

• Reviewing .md files on disk (use /codex-review-doc — different artifact: filesystem path vs in-context plan text)
• Reviewing lifecycle specs 1-requirements.md / 2-tech-spec.md (use /review-spec)
• Code review (use /codex-review-fast)
• Not in plan mode / no plan draft exists
