Codex Plan Review

Independent cross-model review of implementation plans. Codex reviews, Claude revises spec.md and prd.json directly, you decide when it's good enough.

When to Use

• After /workflows:plan or /deepen-plan, before /workflows:work
• High-stakes plans: auth, payments, data models, multi-service coordination
• Plans that will take days to implement
• When you want a genuinely independent perspective (not same-model echo chamber)

When to Skip

• Simple bug fixes, small changes
• Already-validated approaches
• Speed matters more than thoroughness
