What are the prerequisites for using this skill?

Users must have the Codex CLI installed (via npm or Homebrew) and configured on their local system before activating the skill in Claude Code.

Does this skill support file writing?

Yes, when used with the Workspace-Write or --full-auto flags, the skill can safely modify, create, and delete files within your project workspace.

Is it safe to run autonomous code changes?

The skill utilizes sandbox policies to restrict access. While 'Workspace-Write' is recommended for most tasks, 'Read-Only' is available for safe analysis, and 'Danger-Full-Access' is restricted to explicit requests.

Which AI models can this skill use?

The skill is designed to leverage GPT-5 and GPT-5.1 models through the Codex CLI for high-reasoning programming tasks.

What is the primary benefit of the Codex Skill?

It allows Claude to execute complex tasks autonomously without asking for approval at every step, significantly speeding up implementation and refactoring workflows.

Codex Autonomous Execution

生产力与工作流

Enables autonomous, hands-off task execution using the Codex CLI to implement features, fix bugs, and refactor code without constant approval prompts.

关于

This skill integrates the Codex CLI into Claude's workflow, allowing for non-interactive automation of complex programming tasks. By leveraging advanced models like GPT-5.1, it can execute end-to-end implementations—from bug fixes to full feature development—using various sandbox modes to ensure security while maintaining high autonomy. It is ideal for developers who want to delegate implementation plans to an AI agent that operates independently, providing real-time progress updates and structured final summaries rather than pausing for every minor decision.
