SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It reduces the time and coordination required to implement, refactor, and review code changes by delegating work to OpenAI Codex via a terminal workflow.

Core Features & Use Cases

  • Feature building and refactoring: Have Codex execute prompts to modify a codebase, including long-running automated sessions.
  • PR reviews: Run Codex against a pulled PR diff in a cloned temporary repo for safer review workflows.
  • Parallel issue fixing: Use git worktrees to run multiple Codex instances simultaneously for independent issue scopes.

Quick Start

Use the codex skill to build a new feature in your current git repository by asking it to run Codex on your prompt using an interactive terminal session.

How do I automate code reviews for pull requests using Codex CLI?▼

Automate code reviews by running Codex against a pulled PR diff in a cloned temporary repository, enabling safer review workflows without modifying your primary git checkout.

Can I run multiple Codex instances in parallel to fix independent git issues?▼

Run multiple Codex instances simultaneously by utilizing git worktrees for independent issue scopes, allowing parallel terminal-driven execution for faster throughput.

How do I delegate refactoring tasks to OpenAI Codex from a terminal?▼

Delegate refactoring tasks by executing Codex prompts within your git repository using interactive PTY or background orchestration with full-auto mode for safe automated changes.

What do I need to set up before using Codex for feature development?▼

Setup requires the Codex CLI installed, a working git checkout, and interactive PTY or background orchestration configured for safe automated terminal-driven execution.

Does Codex CLI work with full-auto mode for safe automated code changes?▼

Codex CLI supports full-auto mode and exec orchestration to safely apply automated code changes during long-running feature building and refactoring sessions.

When should I use git worktrees for parallel issue fixing instead of a single checkout?▼

Use git worktrees for parallel issue fixing when managing independent issue scopes simultaneously, preventing branch conflicts and maximizing throughput across multiple Codex instances.
