Codex PR Review Toolkit — Git skill for Claude Code

Codex PR Review Toolkit

This is simply a Codex-native version of Anthropic's [Claude PR Review Toolkit](https://github.com/anthropics/claude-code/tree/main/plugins/pr-review-toolkit).

It brings the same focused-review approach to Codex and adds the independent validation pattern from Anthropic's [code-review workflow](https://github.com/anthropics/claude-code/blob/main/plugins/code-review/commands/code-review.md).

What it does

• Runs codex review against the pull request base.
• Uses independent, read-only reviewers for correctness, tests, silent failures, contracts/types, and comments/docs when relevant.
• Revalidates every candidate finding with a fresh agent.
• Reports only high-confidence issues with exact file and line evidence.
• Rejects speculative, pre-existing, stylistic, and linter-detectable findings.
• Includes a separate skill for generating repository-specific ## Code Review Rules in AGENTS.md.
• Keeps code simplification optional and separate because it modifies code.

Install

codex plugin marketplace add neonwatty/codex-pr-review-toolkit
codex plugin add codex-pr-review-toolkit@codex-pr-review-toolkit

Start a new Codex task after installation so the skills are loaded.

Use

Ask Codex to:

• “Review this pull request against its base.”
• “Generate repository-specific Code Review Rules in AGENTS.md.”
• “Simplify the reviewed changes without changing behavior.”
