Dual-Model Cross-Review Coding Workflow
sameerpeace · reddit · 2026-07-18
The author originally used Claude Code for weekly development updates but later combined Claude and Codex into a workflow where they cross-review each other for errors, rather than relying on a single-model fallback.
Two Skills
- /dual-plan: Claude writes the plan first, and Codex reads the actual code and tries to overturn it. They go back and forth for up to 3 rounds; if disagreements remain, the author makes the final call.
- /dual-review: Before merging, both models review the same diff simultaneously, tagging which model discovered which issue.
Actual Results
The author notes that this method not only allows the two models to spot bugs from different angles but also caught the following before releasing the skills repo:
- A deprecated parameter
- An incorrect installation command
- An unsafe sandbox recommendation
The project is implemented in two Markdown files under an MIT license, with the repo at SameerKhan/dual-ai-skills.
