Automated safety checks
This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.
Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.
Pinned to a commit: passed

About this skill
What it does
The Codex Review skill leverages OpenAI's GPT-5.2-Codex model to perform specialized code reviews for backend projects. It analyzes code for potential bugs, security vulnerabilities (like SQL injection), and adherence to coding standards. The tool provides structured output in JSON format and integrates with GitHub by adding review comments directly within pull requests. It can also be used in headless mode for CI/CD automation.
When to use it
- Before opening a Pull Request: Review changes against the base branch (e.g.,
main) to identify issues before merging. - Before committing code: Analyze staged, unstaged, and untracked changes to catch problems early.
- Analyzing specific commits: Examine particular commit SHAs from your project's history.
- Automated CI/CD pipelines: Integrate Codex Review into automated workflows for continuous code quality checks.
Key capabilities
- Uses OpenAI’s GPT-5.2-Codex, specifically trained for code review.
- Detects bugs, security flaws, and style issues (reported 88% detection rate on LiveCodeBench).
- Provides structured output in JSON schema format.
- Integrates natively with GitHub to add comments directly to pull requests.
- Supports headless mode for CI/CD automation.
- Offers review presets for common use cases (base branch, uncommitted changes, specific commits).
- Allows custom instructions to focus the review on particular areas (e.g., security vulnerabilities).
Example prompts
/review- Initiates an interactive code review session.- "Review against base branch" - Compares current changes with the
mainbranch. - "Focus on security vulnerabilities" - Instructs Codex to prioritize identifying potential security issues.
Tips & gotchas
- Prerequisites: Requires Node.js version 22 or higher and either a ChatGPT Plus/Pro/Team/Edu/Enterprise subscription or an OpenAI API key.
- Authentication: Ensure you are properly authenticated with either your ChatGPT account or by setting the
OPENAI_API_KEYenvironment variable. - Interactive Mode: The initial interaction is through a text-based user interface (TUI).
