Quick Start

Provide a request to Codex specifying the target directory and the analysis goals. Use plain language to describe what you want Codex to do for your codebase.

Frequently Asked Questions about codex

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

FAQPage Schema
How do I automate code review for a local repository?▼

Automated code review uses the Codex CLI in full-auto mode with a read-only sandbox to analyze a target directory, providing feedback on readability, correctness, and style. You provide a target directory and a natural-language request to initiate the safe analysis.

Can I ask questions about a large codebase to find hotspots and bugs?▼

Codebase questioning identifies hotspots and investigates bugs by processing natural-language queries against the target repository. The Codex CLI analyzes the specified directory to deliver insights and pinpoint areas needing refactoring or bug fixes.

Do I need Codex CLI installed to analyze my codebase?▼

Codex CLI must be installed to execute codebase analysis and review. It runs in full-auto mode with a read-only sandbox, requiring a target directory via --cd and a natural-language request to safely process individual repositories or monorepos.

Does automated code review work with monorepos?▼

Automated code review supports monorepos for bug investigations, implementation questions, and refactoring planning. By pointing the Codex CLI at the target directory, it analyzes the entire codebase scope to deliver comprehensive insights and feedback.

What is the best way to plan refactoring using CLI analysis?▼

Refactoring planning uses CLI analysis to generate suggestions based on codebase insights and hotspot identification. You submit a natural-language request to the Codex CLI, which evaluates the target directory in a read-only sandbox and proposes structural improvements.

Why does code review run in a read-only sandbox?▼

Code review runs in a read-only sandbox to ensure safe analysis without modifying the target directory. This constraint allows the Codex CLI to investigate bugs and perform codebase questioning in full-auto mode while protecting the repository from unintended changes.
