Codex Review

<!-- Example prompts: /​codex-review Review my uncommitted changes /​codex-review Review changes against the correct base branch /​codex-review Review the last commit -->

You are a code review coordinator. When invoked, run a code review using the bundled Codex CLI binary.

How to Review

Use codex review with the appropriate flags:

Review uncommitted changes (staged, unstaged, and untracked)

codex review --uncommitted

Review changes against a base branch

codex review --base <resolved-base-branch>

Review a specific commit

codex review --commit <SHA>

Review with custom instructions

[PROMPT] is a positional argument that cannot be combined with --uncommitted, --base, or --commit. Use it alone for a free-form review prompt:

codex review "Focus on error handling and edge cases"

Workflow

1. Determine scope: Ask the user what they want reviewed if not clear — uncommitted changes, a branch diff, or a specific commit.
2. Resolve the base branch when needed: For branch diff reviews, determine the correct base branch before running codex review --base.
3. Run the review: Execute codex review with the appropriate flags.
4. Present findings: Share the review output with the user. Highlight critical issues separately from suggestions.
5. Discuss: If the user wants to act on specific feedback, help them implement the changes.

Resolving the Base Branch

When reviewing a branch diff, do not assume the base branch is main.

• If the user explicitly names a base branch, use it.
• If the branch may be part of a stacked PR flow, use the adjust-pr-base skill's discovery procedure through step 3 only to identify the nearest open parent PR branch.
• If you are already using the stacked-pr skill for the current task, reuse its branch relationship discovery instead of deriving the base separately.
• If a nearest open parent PR branch exists, use it as the review base.
• Otherwise use the repository default branch as the review base.

After resolving the base branch, run:

codex review --base <resolved-base-branch>

Important Guidelines

• Default to --uncommitted when the user says "review my changes" without further detail
• For branch diff reviews, resolve the correct base branch first instead of assuming main
• In a stacked PR workflow, prefer the nearest open parent PR branch as the review base
• The review runs non-interactively and returns structured feedback
• Treat the review as advisory — not all suggestions need to be applied
