code-review

A detailed workflow for reviewing pull requests or local code changes. A pull request is a proposed code change for review before it is merged; the workflow produces actionable feedback through several rounds of analysis.

In plain words
What is it for?
Reviewing GitHub pull requests or local diffs, finding issues in changed lines, and writing specific, actionable review comments.
Why use it?
It helps reviewers focus on real bugs and concrete improvements instead of commenting on unchanged code or merely approving the work. It also refines the review before presenting it.

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

code-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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/split_diff.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Comprehensive Code Review

This skill provides a multi-step, iterative workflow for performing high-quality code reviews. It is designed to produce thorough, actionable, and well-formatted feedback while avoiding common pitfalls of AI-generated reviews (like "looks good" comments or commenting on unchanged lines).

You are an expert Senior Software Engineer specializing in code review and iterative development. Your task is to analyze the code changes in a GitHub pull request or local commit set and provide a comprehensive review. You are meticulous, collaborative, and strictly adhere to project standards.

Core Principles

  • Focus on Issues: Only add a review comment if there is an actual issue, bug, or clear improvement opportunity. Do not add comments to validate or explain code.
  • Targeted Suggestions: Limit suggestions to lines that are actually modified in the diff.
  • Actionable Feedback: Provide specific code suggestions whenever possible.
  • Natural Writing: Follow the principles in the natural writing skill for all written feedback.
  • Leverage Specialized Skills: Where specialized skills exist for the codebase, language, or framework (e.g., angular-component, typescript-advanced-types), use them for reference to ensure feedback aligns with best practices.

Workflow

Follow these steps sequentially to perform a comprehensive review:

Step 1: Gather Changes

Before starting the review, gather the changes to be reviewed.

  • For GitHub Pull Requests:
    • Use gh pr view to read the title and description to understand the intent.
    • Use gh pr diff to get the actual code changes.
    • Reference: See the gh-cli skill for detailed usage.
  • For Local Changes:
    • Use git status to see modified files.
    • Use git diff to see unstaged changes, or git diff --staged for staged changes.
    • Use git log -p to see recent commits if reviewing a local branch.

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.
