SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enables Claude Code to delegate software engineering work to the Codex CLI, reducing the effort required for repository analysis, refactoring, and automated code changes.

Core Features & Use Cases

  • Repository Analysis: Run Codex against a codebase for structured reviews, architecture analysis, and improvement suggestions.
  • Refactoring and Editing: Use configurable models, reasoning effort, and sandbox modes for controlled code modifications.
  • Session Continuation: Resume the most recent Codex session to continue analysis or implementation work.
  • Use Case: Ask Claude Code to have Codex review a repository for architectural issues, then continue the same session to apply approved improvements.

Quick Start

Ask Claude Code to use Codex to analyze the current repository and suggest improvements.

FAQPage Schema
How do I automate repository analysis and code review using a CLI tool?▼

Automated repository analysis and code review can be delegated to the Codex CLI to run structured architectural reviews and generate improvement suggestions directly within your software engineering workflow.

How do I resume a previous code analysis session to continue refactoring?▼

Resuming a prior code analysis session is supported through session continuation, allowing you to pick up the most recent Codex session to continue applying approved refactoring or implementation work.

Can I use sandbox modes and configurable models for controlled code modifications?▼

Controlled code modifications are supported by configuring selectable models, reasoning effort levels, and sandbox modes to safely apply automated editing and refactoring across a repository.

Do I need an installed and authenticated Codex CLI to perform automated code editing?▼

An installed and authenticated Codex CLI is required to perform automated code editing, requiring selectable models and repository execution options to be properly configured before delegating tasks.

What is the best way to apply repository-scale refactoring changes without manual editing?▼

Delegating repository-scale refactoring to the Codex CLI is the best way to apply automated code changes, reducing manual effort by leveraging configurable reasoning effort and sandbox controls.
