Agent conversations

TLDR

You can have Claude talk to Codex for better results at agentic tasks. What works well in May 2026:

Wire Codex in as an MCP to Claude code. Claude stays as the main loop. 1 minute effort, find the latest instructions by search or ask Claude.
From that point on, Claude can consult Codex.
Done.

For tasks where code quality matters, you can now use one of the prompting patterns:

“Come up with the implementation plan, then discuss with Codex. Discuss the feedback. Once the conclusion is reached, implement.”

Or have Claude implement something, then prompt it to ask for Codex to review.

I usually like to prompt the planning, codex review, review discussion and implementation in a single prompt. This way, the human is only brought to context once the dirty work is done.

Footnote

I heard about it peripherally about a few months ago.

Testimony about this method’s effectiveness was vouched by a colleague a few weeks ago on a Monday. I implemented it for myself the same week Tuesday. By Friday, it seemed odd if someone is not using this method.

This post will either sound mind-blowing to you or completely trivial, depending on where you are located on the AI exponential.
