A claude code skill to delegate prompts to codex

What it solves

This project provides an integration that allows Claude Code to use the Codex CLI for automated code analysis, refactoring, and editing. It bridges the gap between Claude's interface and Codex's specialized code-processing capabilities.

How it works

It functions as a plugin or standalone skill for Claude Code. Once installed, Claude can invoke the codex exec command and manage session resumes. It allows the user to specify models (such as gpt-5.3-codex), reasoning effort levels (low, medium, high), and sandbox modes (like read-only) to execute complex code tasks.

Who it’s for

Developers using Claude Code who want to leverage the Codex CLI's automated analysis and refactoring tools directly within their workflow.

Highlights

  • Plugin Integration: Supports installation via Claude Code's plugin marketplace or as a standalone skill.
  • Context Management: Suppresses thinking tokens by default to prevent bloating the context window, while allowing users to explicitly request them for debugging.
  • Configurable Execution: Enables selection of specific AI models and reasoning effort levels for tailored code analysis.
