Reviewing your own code with the agent that wrote it just rubber-stamps decisions — explicitly delegate to parallel subagents, each with a different lens. When the same Codex context that wrote the code reviews it, the reviewer just nods along. OpenAI's docs recommend fanning out to parallel subagents with separate context windows. Use the words 'spawn' or 'delegate in parallel' explicitly — Codex won't parallelize on its own. Drop to gpt-5.4-mini for the subagents to keep costs low. Implementation example: Review this branch with parallel subagents. Spawn one subagent for security risks, one for test gaps, and one for maintainability. Use gpt-5.4-mini for the subagents.
