SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Orchestrates a looping workflow where Claude Code plans and implements, Codex validates, and feedback drives iterative improvements.

Core Features & Use Cases

Phase-based loop: Plan, Validate, Implement, Review, Refine, Re-validate.
Resume: Use codex resume to continue sessions with preserved context.
Cross-review: Codex validates Claude outputs for quality gates.

Quick Start

Plan with Claude Code, validate with Codex, implement, and resume validation as needed.

FAQPage Schema

How do I set up a planning and validation loop for multi-step feature development?▼

A planning and validation loop automates software engineering by having one agent plan and implement while another validates the output. Claude Code handles planning and implementation; Codex reviews for quality gates. This structured handoff ensures code meets requirements before deployment and catches issues early in development cycles.

Can I resume a code review session after validation stops?▼

Yes, the Codex resume function preserves context across sessions, allowing you to continue validation and refinement without losing your workflow state. Use codex resume to pick up where you left off, maintaining the full history of planning decisions and validation feedback.

What's the best way to coordinate code planning and review across multiple iterations?▼

The dual-AI loop coordinates planning, validation, implementation, review, and refinement phases sequentially. Claude Code generates plans and code; Codex validates outputs; feedback drives iterative improvements. This phase-based approach ensures each stage has explicit handoff logging and robust error handling.

How does cross-AI validation improve code quality in bug fixes and feature work?▼

Cross-AI validation applies independent review standards to each output stage. Codex validates Claude Code's plans and implementations against quality gates, catching logic errors, edge cases, and requirement mismatches that single-pass development misses. Explicit validation checkpoints reduce rework and production issues.

When should I use a dual-AI loop instead of single-agent development?▼

Use a dual-AI loop when planning rigor, explicit validation, and iterative refinement are critical—particularly in multi-step features, complex bug fixes, or code reviews requiring structured approval. Single-agent workflows skip validation phases; loops enforce quality gates and preserve reasoning traces for audit and resume capability.
