A claude code skill to delegate prompts to codex

What it solves

This project provides an integration that allows Claude Code to utilize the Codex CLI for automated code analysis, refactoring, and editing. It bridges the gap between the Claude Code environment and the powerful analysis capabilities of the Codex CLI tool.

How it works

It functions as a plugin or standalone skill for Claude Code. When a user asks Claude to perform a task using Codex, the plugin enables Claude to execute codex exec commands with specific parameters, such as model selection (e.g., gpt-6-astra), reasoning effort levels, and sandbox modes (like read-only for analysis).

Who it’s for

Developers using Claude Code who want to leverage the Codex CLI's specialized code analysis and refactoring workflows directly within their AI-assisted coding environment.

Highlights

  • Flexible Model Configuration: Allows selection of various models and reasoning effort levels (from low to ultra).
  • Context Window Management: Suppresses thinking tokens by default to prevent bloating the context window, while allowing users to explicitly request them for debugging.
  • Multiple Installation Options: Can be installed as a plugin via the Claude Code marketplace or as a standalone skill folder.
