Codex Reviewer

Codex Reviewer

Use this skill to ask Codex, running GPT-5.5 through the local codex CLI, for an independent code review.

Run it when the user invokes /codex-reviewer:codex-reviewer or explicitly asks for a Codex/GPT-5.5 reviewer. Because this spends external model/API budget, do not invoke it for ordinary Claude-only review requests unless the user asks for Codex, GPT-5.5, OpenAI, or a second-opinion reviewer.

Invocation

Run the helper script from the current repository:

run-codex-review $ARGUMENTS

If no arguments are provided, review uncommitted changes.

Supported presets:

• uncommitted: review staged, unstaged, and untracked changes.
• base <branch>: review changes against a base branch, such as base main or base origin/main.
• commit <sha>: review the changes introduced by a specific commit.
• custom <instructions>: run Codex's custom review-instructions mode.

Codex review presets are mutually exclusive. Do not combine uncommitted, base, or commit with extra review instructions; use custom <instructions> instead.

Examples:

• /codex-reviewer:codex-reviewer
• /codex-reviewer:codex-reviewer uncommitted
• /codex-reviewer:codex-reviewer base origin/main
• /codex-reviewer:codex-reviewer commit abc1234
• /codex-reviewer:codex-reviewer custom Review uncommitted changes and focus on concurrency and missing tests

How to Use the Result

After the helper returns:

1. Treat the Codex report as reviewer input, not as automatically true.
2. Preserve concrete findings with file/line references.
3. If Codex reports no findings, say that clearly and include any test or verification gaps it noted.
4. If Codex fails to run, report the command failure and do not invent review findings.

Do not edit files as part of this skill unless the user separately asks for fixes.
