To get a second opinion on code changes, this Skill invokes OpenAI Codex with your repository context and git diff. It returns unfiltered critical feedback so you can review suggestions without losing important warnings before deciding what to do next.

Yes, you can use Codex to review a git diff before committing. The Skill detects your intent to review changes, sends the diff context to OpenAI Codex, and presents structured critical feedback to help you evaluate your modifications.

Code review feedback gets categorized by tagging each Codex suggestion with actionable labels like adopt, discuss, style, or over-engineered. This structured categorization helps you quickly judge which critical comments require immediate implementation and which are optional.

The best way to handle critical code review suggestions is through the interactive selection UI. After Codex provides categorized feedback, you select which suggestions to act on, and the Skill helps you implement, further analyze, or conclude based on your choices.

Yes, Codex code review works with general file-based assessments. The Skill detects whether you need a file review, git diff change review, or a general assessment, then sends the appropriate context to Codex for critical evaluation across software engineering tasks.

A limitation of using Codex for automated code review is that it requires read-only sandboxed Codex calls. While it provides critical second opinions on code changes, all feedback is unfiltered and requires user judgment to decide which suggestions to implement.
