What is the primary purpose of the Codex skill?

The Codex skill allows Claude Code to use the Codex CLI for autonomous, non-interactive task execution, meaning it can complete complex coding jobs from start to finish without asking for permission at every step.

Which AI models does this skill support?

It supports various OpenAI models, specifically optimized versions like gpt-5.2, gpt-5.2-codex, and other GPT-5 variants available through the Codex CLI.

Can I use this on projects that don't use Git?

Yes, by using the --skip-git-repo-check flag, the Codex skill can operate in any directory regardless of whether it is initialized as a Git repository.

How do I allow the skill to modify my files?

To enable file editing, you should use the '--full-auto' flag or the '-s workspace-write' sandbox mode, which gives the skill permission to read and write within your project directory.

Is it safe to run this skill on my production code?

The skill includes sandbox levels to manage risk. For analysis, use 'read-only'. For programming, use 'workspace-write'. Avoid 'danger-full-access' unless you are in a secure, containerized environment.

生産性とワークフロー

Executes autonomous code implementation and system tasks using OpenAI Codex and GPT models via a specialized CLI integration.

概要

The Codex Skill empowers Claude Code to operate in a high-autonomy mode for hands-off task execution. By leveraging the Codex CLI, this skill allows Claude to plan, implement, and verify complex programming tasks from start to finish without requiring constant user approval. It features sophisticated sandbox management—ranging from safe read-only analysis to full workspace-write capabilities—and supports advanced model selection including GPT-5 variants. This skill is ideal for developers looking to delegate entire workflows like refactoring, bug fixing, or feature implementation to a trusted autonomous agent.
