Reacting to a question about killing plan mode in Claude Code, user mikegiannulis shared his workflow: generate the plan in plan mode, then submit it via CLI tools and webhooks to Codex for a second review that catches bugs and issues.

Claude and Codex iterate back and forth on the plan until it's accepted — sometimes taking up to 10 rounds. A two-model cross-review setup that filters out design flaws before any code gets written.
