SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @openai/codex.

What problem does it solve? Running autonomous coding work like feature builds, refactors, and PR reviews by hand is slow and repetitive. This Skill lets you delegate those tasks to OpenAI's Codex CLI directly from the Robo terminal, including long-running background jobs and parallel batch work. ## Core Features & Use Cases - One-Shot Execution: Run single coding tasks with codex exec and exit cleanly when done. - Background & Parallel Workflows: Launch long refactors in the background, monitor with the process tool, and run multiple Codex sessions across git worktrees for batch issue fixing. - PR Reviews at Scale: Clone repos to temp directories and review individual or batches of pull requests with codex review. - Use Case: You have two open issues in a repository. Create two git worktrees, launch a Codex process in each with a fix prompt, monitor progress, then push branches and open PRs with gh. ## Quick Start Ask the agent to run codex exec with a prompt like "Add dark mode toggle to settings" inside your git repository using a PTY terminal session.

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

Use codex exec followed by your prompt in quotes, run inside a git repository with pty=true in the terminal call. Codex executes the task and exits cleanly when finished.

How to run Codex in the background for long tasks?▼

Launch codex exec with background=true and pty=true, which returns a session_id. Monitor progress with process poll and log actions, submit input if Codex asks questions, and kill the session if needed.

Does Codex CLI work outside a git repository?▼

No, Codex refuses to run outside a git repository. For scratch work, create a temporary directory with mktemp -d, run git init inside it, then execute your Codex command there.

Why does Codex sandbox fail with permission denied errors?▼

The workspace-write sandbox can fail in gateway or service contexts with bubblewrap user-namespace errors like uid map permission denied. In that context, use --sandbox danger-full-access and rely on process boundaries and git diff review for safety.

Can I fix multiple GitHub issues in parallel with Codex?▼

Yes, create a separate git worktree per issue, launch a Codex background process in each with a fix prompt, then push the branches and create PRs with gh. Clean up worktrees after completion.
