I had a prompt I used for this just using Claude Code:

    Let's review <filepath or specific file> for architectural issues. Spawn 10 agents, create personas for them, have them review the _api.go and write their review to reviews/<persona>-review.md, then have each agent do a round robin response to 3 of the reviews of their choosing (based on the abstract at the beginning of each review) and write the response to response/<original file name>-<agent persona name>-response.md. Then we do rebuttals to the responses in rebuttals/<response file name>-rebuttal.md. Finally, each agent should launch agents to review the reviews, responses, and rebuttals to their review, and compile findings to findings/<original file name>-findings.md. Finally, have another agent compile the findings and write that to review-findings.md. Present a concise version of the findings here.

This works well with frontier models and even locally hosted models (last I used it was with Qwen 3.5).
