What problem does it solve?

OpenAI Codex CLI wrapper — three modes: code review with independent diff review and gate, adversarial challenge that attempts to break your code, and consult mode with session-continuity for follow-ups. It’s designed to be used inside gstack to provide a quick, controlled Codex workflow for developers.

Core Features & Use Cases

  • Code review: independent diff review with pass/fail gate
  • Challenge: adversarial mode that tries to break your code
  • Consult: ask Codex with session continuity for follow-ups
  • Voice triggers: speech-to-text aliases

Quick Start

Run the codex review command on a feature branch to begin an independent diff review and gate the results.

FAQPage Schema
How do I automate code review on a feature branch using a CLI workflow?

Automating code review on a feature branch involves running the codex review command, which performs an independent diff review and applies a pass/fail gate to the results.

Can I run adversarial testing to try and break my code changes?

Adversarial testing to break code changes is supported through the challenge mode, which actively attempts to find flaws and break your code before approval.

Does the Codex consult mode support session continuity for follow-up prompts?

Codex consult mode supports session continuity for follow-up prompts, allowing you to ask questions and maintain context across multiple interactions within the same workflow.

What is the best way to integrate a pass/fail gate into an automated code review workflow?

Integrating a pass/fail gate into an automated code review workflow is managed by declaring allowed tools in the frontmatter and using a self-contained workflow controlled by SKILL.md within gstack.

Do I need gstack to use the Codex CLI for code reviews and tests?

You need gstack to use the Codex CLI wrapper, as it is designed to provide a quick, controlled Codex workflow for developers directly inside the gstack environment.
