FAQPage Schema

How do I delegate coding tasks to an AI agent for feature development?▼

You can delegate coding tasks to an AI agent by sending natural language prompts to the OpenAI Codex CLI, which handles feature development, refactoring, and code reviews automatically within your git repository.

Can I fix multiple code issues concurrently using git worktrees?▼

Yes, you can fix multiple code issues concurrently by executing background AI tasks across separate git worktrees, enabling parallel issue resolution without branch conflicts in your local development environment.

Do I need an OpenAI API key to automate code reviews with Codex?▼

Yes, automating code reviews requires an OpenAI API key and a local installation of the Codex CLI. You must also execute the agent within a git repository that has PTY enabled.

What is the best way to automate code refactoring using natural language?▼

The best way to automate code refactoring is using a one-shot task prompt with the Codex CLI agent, which analyzes your existing codebase and applies quality improvements directly through background execution.

Why does the Codex CLI require PTY enabled in my git repository?▼

PTY must be enabled in your git repository because the Codex CLI agent requires a pseudo-terminal interface to properly execute interactive background tasks, manage parallel git worktrees, and stream automated code generation outputs.

Are there limitations when running batch code generation tasks in a local environment?▼

Batch code generation is limited to environments with the Codex CLI installed and an active OpenAI API key, requiring PTY support within a git repository to successfully manage concurrent background executions.
