Ask for a decision, not a reassuring paragraph
A useful planning request names the behavior that should change, the constraints that matter, and how you will verify the result. Ask the author to identify the files and dependencies it needs to inspect. For a migration, require a rollback approach and an account of data compatibility.
The more precise the request, the more meaningful the second opinion can be. A reviewer cannot prove an unstated requirement. Put the important boundaries in the prompt rather than assuming both providers will discover the same product intent.
Follow the author, reviewer, revision sequence
Choose Codex or Claude as the author. The other provider performs the critical review, and the original author receives that feedback to revise the plan. VibeiDE keeps the workflow and its provider order together instead of requiring you to copy between terminal windows.
The workflow waits for the provider capacity it needs. Its output is a reviewed plan, not an automatic implementation. Read the revision and use the separate execution handoff when it is ready. That boundary gives you a concrete artifact to assess before writable work begins.
Look for disagreement that changes the approach
Useful review comments point to a failure mode: a missing authorization check, a query that cannot scale, a date boundary that changes totals, or a test that mirrors the implementation without verifying the outcome. Ask how each material comment changes the revised plan.
If the review only restates the proposal, add a more specific challenge. If the author rejects a comment, read the explanation. The value comes from clearer decisions and explicit checks, not from the presence of two model names on a finished document.
Keep the implementation review separate
A plan cannot prove the resulting code will follow it. After execution, inspect the task result and available patches, and run the checks appropriate to the change. Ready for review records an unread completion, not approval of the implementation.
For a small, bounded edit, direct execution may be enough. Reserve Plan council for decisions where an additional pass can expose a meaningful mistake. VibeiDE offers both workflows so planning effort can match the consequence of the change.
