SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Cross-reviewing coding tasks by running two leading AI coding agents (Codex and Claude Code) in parallel to generate independent plans and a final best plan, improving quality and reducing bias.

Core Features & Use Cases

  • Independent Round 1 planning: both agents generate high-level implementation plans for the given feature.
  • Round 2 revised plans: each agent reviews the other agent's R1 plan and produces a refined plan.
  • Best-plan synthesis: a consolidated plan that merges strengths and resolves disagreements.
  • HTML report: an accessible, side-by-side comparison of plans and the final verdict.

Quick Start

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I cross-review code using multiple AI agents?

You can cross-review code by pairing Codex and Claude Code to run a structured four-round workflow. Both agents generate independent plans, revise each other's work, and synthesize a final best plan delivered as an HTML report.

What is the best way to compare implementation plans from different AI coding assistants?

Comparing implementation plans from different AI coding assistants is best handled by a structured cross-review that produces an HTML report. This report consolidates independent and revised plans into a single final best plan for side-by-side comparison.

Can I use Claude Code and Codex together for feature development planning?

Yes, you can use Claude Code and Codex together for feature development planning. The cross-review workflow pairs them to independently plan, review each other's proposals, and merge strengths to reduce bias and improve feature implementation quality.

How does a four-round cross-review process work for coding tasks?

A four-round cross-review process for coding tasks works by having two AI agents generate independent plans in round one, review and refine each other's plans in round two, and ultimately synthesize a consolidated best plan to reduce individual agent bias.

Does cross-reviewing code with AI work across multiple repositories?

Cross-reviewing code with AI does work across multiple repositories. The workflow applies to feature development tasks where planning and cross-checking across two AI agents are required, explicitly supporting validation steps across multiple repositories.
