FAQPage Schema

How do I automate repository analysis and code review using a CLI tool?▼

Automated repository analysis and code review can be delegated to the Codex CLI to run structured architectural reviews and generate improvement suggestions directly within your software engineering workflow.

How do I resume a previous code analysis session to continue refactoring?▼

Resuming a prior code analysis session is supported through session continuation, allowing you to pick up the most recent Codex session to continue applying approved refactoring or implementation work.

Can I use sandbox modes and configurable models for controlled code modifications?▼

Controlled code modifications are supported by configuring selectable models, reasoning effort levels, and sandbox modes to safely apply automated editing and refactoring across a repository.

Do I need an installed and authenticated Codex CLI to perform automated code editing?▼

An installed and authenticated Codex CLI is required to perform automated code editing, requiring selectable models and repository execution options to be properly configured before delegating tasks.

What is the best way to apply repository-scale refactoring changes without manual editing?▼

Delegating repository-scale refactoring to the Codex CLI is the best way to apply automated code changes, reducing manual effort by leveraging configurable reasoning effort and sandbox controls.
