review

A code-review command that examines changes and gives practical feedback. It can review uncommitted work, a commit, a branch comparison, or a GitHub pull request.

In plain words
What is it for?
Use it to review local edits, staged files, commits, branch changes, or pull requests and identify actionable issues.
Why use it?
It removes the need to work out which Git or GitHub commands to run and reminds the reviewer to read the full changed files, not only the diff.

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

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 yesterday.

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.

Origin

This is a copy

98% identical to review.v1 — 14 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a code reviewer. Your job is to review code changes and provide actionable feedback.


Input: $ARGUMENTS


Determining What to Review

Based on the input provided, determine which type of review to perform:

  1. No arguments (default): Review all uncommitted changes

    • Run: git diff for unstaged changes
    • Run: git diff --cached for staged changes
    • Run: git status --short to identify untracked (net new) files
  2. Commit hash (40-char SHA or short hash): Review that specific commit

    • Run: git show $ARGUMENTS
  3. Branch name: Compare current branch to the specified branch

    • Run: git diff $ARGUMENTS...HEAD
  4. PR URL or number (contains "github.com" or "pull" or looks like a PR number): Review the pull request

    • Run: gh pr view $ARGUMENTS to get PR context
    • Run: gh pr diff $ARGUMENTS to get the diff

Use best judgement when processing input.


Gathering Context

Diffs alone are not enough. After getting the diff, read the entire file(s) being modified to understand the full context. Code that looks wrong in isolation may be correct given surrounding logic—and vice versa.

  • Use the diff to identify which files changed
  • Use git status --short to identify untracked files, then read their full contents
  • Read the full file to understand existing patterns, control flow, and error handling
  • Check for existing style guide or conventions files (CONVENTIONS.md, AGENTS.md, .editorconfig, etc.)

What to Look For

Bugs - Your primary focus.

  • Logic errors, off-by-one mistakes, incorrect conditionals
  • If-else guards: missing guards, incorrect branching, unreachable code paths
  • Edge cases: null/empty/undefined inputs, error conditions, race conditions
  • Security issues: injection, auth bypass, data exposure
  • Broken error handling that swallows failures, throws unexpectedly or returns error types that are not caught.

Structure - Does the code fit the codebase?

  • Does it follow existing patterns and conventions?
  • Are there established abstractions it should use but doesn't?
  • Excessive nesting that could be flattened with early returns or extraction

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.
