codex-cross-review

What problem does it solve?

Prevents single-model bias and premature phase completion by providing an independent, structured second-reviewer using the Codex CLI to validate phase deliverables and surface unresolved disagreements before a phase is closed.

Core Features & Use Cases

• Structured multi-round cross-review dialogue between Claude and Codex with a maximum of five rounds and escalation to the user if consensus is not reached.
• Consensus ledger, anti-oscillation logic, and stability criteria to ensure settled items are preserved and oscillations are detected and mitigated.
• Integration points for phase orchestrators so the cross-review acts as a mandatory penultimate gate that writes detailed artifacts under .rat/cross-review for traceability.
• Use Case: Run at the end of an RTL implementation phase to detect critical issues, produce a cross-review report, and block phase completion until CONSENSUS or explicit user decision.

Quick Start

Invoke the codex-cross-review skill to run a structured multi-round cross-review between Claude and Codex on phase N artifacts and produce a final cross-review report and verdict.
