Consult Codex

Pull a second opinion from Codex while Claude Code is running, and compare both.

What "Consult Codex" Is

Consult Codex runs Codex in the background to give you another viewpoint on whatever Claude Code is currently doing. Use it when you're unsure about the approach or want a comparison.

When to Use It

  • When several implementations look reasonable and you want both proposed
  • When one AI is stuck and you need an outside view
  • To round out a code review with a different lens
  • On meaty design calls — compare conclusions across models

How to Use

  • Type a follow-up in the active Claude Code chat
  • Pick "Also ask Codex" when sending
  • A Codex consultation runs before or alongside Claude Code's turn
  • Codex's verbatim reply is pasted into the chat under a "## Codex の回答" heading

@claude / @codex in Issues

Inside an issue comment, mention both @claude and @codex to fire both in parallel. Multi-AI consultation works in issues too, not only in chat.

Tips That Pay Off

  • "How would another AI answer this?" surfaces real differences better than "give me two options"
  • When one model is stuck, take the other's verdict and move on
  • Keep second opinions on the record for important design choices
