What makes the Codex skill different from standard Claude capabilities?

Codex provides a specialized 'run-fix-verify' loop within a full-access sandbox, allowing it to execute code, run tests, and manage Git workflows autonomously with higher reasoning depth than standard chat models.

Does this skill require human approval for every command?

By default, the Codex skill is configured for non-interactive mode with 'approval=never' to allow the agent to solve complex, multi-step tasks in the sandbox without interruption.

Can Codex handle image or PDF inputs for UI design?

No, Codex is strictly optimized for code and logic. For multimodal tasks involving images or PDFs, it is recommended to use the Gemini skill within the same repository.

What specific model does the Codex skill use?

The skill is specifically designed to use the gpt-5.2-codex model, which is optimized for agentic coding and deep reasoning tasks.

Deployment & DevOps

Automates the full development lifecycle from implementation and testing to pull request creation using high-reasoning autonomous agents.

About

The Codex skill integrates the advanced Codex CLI into Claude Code, enabling a high-autonomy agentic workflow for complex software engineering tasks. It excels at multi-step processes like the 'execution-fix-verification' loop, deep reasoning for performance refactoring, and seamless GitHub integration for PR management. By leveraging a full-access sandbox and the gpt-5.2-codex model with maximum reasoning effort, it allows Claude to function as a self-sufficient developer capable of completing projects, debugging complex stack traces, and fixing broken CI/CD pipelines without constant human oversight.
