What happens if Claude and Codex disagree on a code change?

Claude is instructed to treat Codex as a colleague, not an authority. It will research disagreements, provide evidence, and can even initiate a 'peer discussion' within the Codex session to resolve the conflict.

How does this skill handle security during code execution?

The skill utilizes specific sandbox modes—read-only, workspace-write, or danger-full-access—allowing users to restrict Codex's permissions based on the task requirements.

Does it work within Git repositories?

The skill includes the --skip-git-repo-check flag by default to ensure smooth operation across various directory structures without mandatory git overhead.

Can I continue a previous Codex session?

Yes, the skill supports a 'resume' functionality that pipes your new prompts into the previous context using the 'codex exec resume --last' command.

Which OpenAI models can I use with this skill?

You can specify models such as gpt-5.3-codex or gpt-5.2, and pair them with reasoning effort levels like xhigh, high, medium, or low.

Developer Tools

Delegates complex code analysis and automated refactoring tasks to the OpenAI Codex CLI directly from your workspace.

The Codex CLI Bridge allows Claude to leverage OpenAI Codex for high-intensity coding tasks, including deep code analysis, automated editing, and structural refactoring. It provides a structured interface for executing Codex commands, managing sandbox security levels (read-only to full-access), and fine-tuning reasoning effort. By automating session resumes and handling model-specific configurations, this skill transforms Codex into a collaborative peer that Claude can interact with to solve difficult engineering challenges while maintaining critical oversight and error handling.
