FAQPage Schema
How do I automate coding tasks like feature development and refactoring using OpenAI Codex?▼

Automate coding tasks by running `codex exec` with your specific instruction in the terminal. This delegates feature development, refactoring, and code reviews directly to the OpenAI Codex CLI agent within your git repository.

What do I need to set up before using the Codex CLI for code reviews?▼

To use the Codex CLI for code reviews, you need the codex CLI installed, an active git repository, and an OpenAI API key. These prerequisites enable the AI agent to access your codebase and execute commands.

Can I use OpenAI Codex to write new features directly from the terminal?▼

Yes, you can write new features directly from the terminal by executing `codex exec` followed by your feature description. OpenAI Codex CLI processes the prompt and automates the coding within your git repository context.

How does AI code review with OpenAI Codex work within a git repository?▼

AI code review works by executing `codex exec` with your review request inside a git repository. The Codex CLI analyzes the repository context and pull requests, automating the review process to reduce manual effort.

What are the limitations of automating refactoring with an AI coding agent?▼

Automating refactoring with this AI coding agent requires a git repository context and cannot operate outside of it. Additionally, you must supply a valid OpenAI API key and have the codex CLI installed to execute any tasks.
