SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @openai/codex.

What problem does it solve? It lets you offload feature building, refactoring, PR reviews, and batch issue fixing to OpenAI's autonomous Codex CLI without leaving your agent workflow, including long-running background jobs and parallel worktree execution. ## Core Features & Use Cases - One-Shot Execution: Run codex exec with sandboxed auto-approval for quick feature builds and refactors inside any git repository. - Background & Parallel Workflows: Launch long tasks in background sessions, monitor with process polling, and fix multiple issues simultaneously using git worktrees. - PR Review Automation: Clone repos to temp directories and run codex review against base branches, including batch reviews of multiple pull requests. - Use Case: You have two open bug issues. Create two git worktrees, launch a Codex process in each with the issue description, monitor progress, then push branches and open PRs automatically. ## Quick Start Ask the agent to run Codex in your project to add a dark mode toggle to the settings page using a sandboxed one-shot execution.

Frequently Asked Questions about codex

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run OpenAI Codex CLI for a one-shot coding task?▼

Use `codex exec "your prompt"` inside a git repository with a PTY-enabled terminal. Codex runs the task and exits cleanly when finished, making it suitable for single features or fixes.

How to fix multiple GitHub issues in parallel with Codex?▼

Create a separate git worktree per issue with `git worktree add`, then launch a background Codex process in each worktree with the issue description. Monitor with process polling, push branches, and open PRs when done.

Does Codex CLI work outside a git repository?▼

No, Codex refuses to run outside a git repository. For scratch work, create a temporary directory and run `git init` before invoking Codex.

Why does Codex sandbox fail with permission denied errors?▼

The workspace-write sandbox can fail in gateway or service contexts due to bubblewrap user-namespace restrictions. Use `--sandbox danger-full-access` instead and rely on process boundaries like explicit workdir and git diff review for safety.

What sandbox flag should I use for automated Codex builds?▼

Use `--sandbox workspace-write`, which auto-approves file changes within the workspace sandbox. The older `--full-auto` flag is deprecated, and `--dangerously-bypass-approvals-and-sandbox` removes all safety checks.
