How does the skill handle security during execution?

It uses a tiered sandbox approach. By default, it operates in Read-Only mode. More permissive modes like Danger-Full-Access, which allow network and system-level changes, must be explicitly granted by the user.

What is 'Full-Auto' mode in the Codex skill?

Full-Auto mode, enabled by the --full-auto or -s workspace-write flag, allows the skill to autonomously read and write files in your project to complete programming tasks without requiring approval for every step.

Which AI models are compatible with this skill?

The skill is designed to work with OpenAI's latest models, including gpt-5.2, gpt-5.2-codex, and gpt-5.2-codex-max, which are optimized for high-quality code generation.

Do I need an external CLI to use this skill?

Yes, this skill requires the Codex CLI to be installed on your system via npm (npm i -g @openai/codex) or Homebrew (brew install codex) before it can be used.

Enables autonomous code generation and execution using OpenAI Codex models to implement features and refactor code.

The Codex skill integrates the OpenAI Codex CLI directly into Claude Code, providing a powerful autonomous agent for codebase management. It allows developers to trigger 'full-auto' mode where the AI can independently analyze, write, and verify code changes across a workspace. By leveraging specialized models like GPT-5.2-codex, this skill streamlines complex tasks such as feature implementation, bug fixing, and security auditing with minimal manual intervention, while offering granular sandbox controls to ensure system safety.
