codex-review

A command for running an OpenAI Codex code review on current changes or a selected branch or commit. It first checks the working directory, Git repository, Codex installation, and review scope.

In plain words
What is it for?
Use it to review uncommitted changes, a branch, or a specific commit in a Git repository. It helps inspect code with additional context and structured analysis.
Why use it?
It catches setup problems before a review starts and gives the review a defined set of changes to inspect. It also stops when there is nothing appropriate to review.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

codex-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Context

  • Working directory: !pwd
  • Codex installed: !codex --version 2>&1 || echo "NOT INSTALLED"
  • Current branch: !git branch --show-current 2>/dev/null || echo "NOT A GIT REPO"
  • Uncommitted changes: !git status --short 2>/dev/null | head -20

Task

Run Codex CLI code review with deep context enrichment and structured analysis.

User arguments: $ARGUMENTS

Pre-checks

  1. If Codex is not installed (version shows "NOT INSTALLED"), tell the user to install it with npm install -g @openai/codex and configure with codex login. Stop here.
  2. If not in a git repo (branch shows "NOT A GIT REPO"), tell the user this command requires a git repository. Stop here.
  3. If uncommitted changes is empty AND ($ARGUMENTS is empty OR $ARGUMENTS is uncommitted), tell the user there are no uncommitted changes and suggest specifying a branch or commit SHA (e.g., /codex-bridge:codex-review main). Stop here.

Step 1: Determine Review Scope

Parse $ARGUMENTS to decide the review mode. When ambiguous, verify with git before deciding:

git branch --list "$ARGUMENTS" 2>/dev/null               # non-empty → branch
git rev-parse --verify "$ARGUMENTS^{commit}" 2>/dev/null  # success → valid commit
$ARGUMENTS Mode Base Command
Empty or uncommitted Uncommitted changes codex review --uncommitted
Verified as a branch name Branch diff codex review --base $ARGUMENTS
Verified as a commit SHA Single commit codex review --commit $ARGUMENTS
Contains natural language Guided review codex review "<enriched prompt>"

Important: Codex CLI does not allow --uncommitted and [PROMPT] together. When providing custom instructions, pass them as the positional argument only — Codex defaults to reviewing uncommitted changes when no scope flag is given.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
