Automated summary

Performs a comprehensive code review using all 30 review checklists via a senior specialist agent.

Strengths

  • Thorough coverage of all aspects (logic, security, architecture, performance, UX)
  • Systematic approach with dedicated checklists
  • Catches diverse and complex issues through specialized agent

Limitations

  • Can be slow and expensive in context (many files processed)
  • Risk of false positives or noise if checklists are not tailored to the project
  • Requires initial setup of checklists
When to use it

Use this review before a major merge or release for deep quality assurance.

When not to use it

Avoid for minor changes or when you need quick feedback, as the process is heavy.

Security analysis

Safe
Quality score90/100

The skill instructs an AI coding agent to perform a code review using a set of checklists. It does not involve any dangerous operations, network access, or data exfiltration. All actions are limited to reading files and running safe git commands.

Agent Instructions

The agent should:

  1. Get working tree changes: Run git diff to see all changes
  2. For each changed file:
    • Read the full file content
    • Go through each diff hunk
    • Apply ALL 30 checklists to the changes
    • Trace problems to their root cause
  3. Cross-reference related files: Follow imports, check callers
  4. Find ALL issues: Be thorough, expect to find many issues

Output Format

Generate a comprehensive review report with:

  • Critical Issues: Blocking problems (must fix)
  • Warnings: Should address before merge
  • Suggestions: Improvements to consider
  • File Summary: Issues per file with counts by severity
  • Overall Assessment: Ship/Don't Ship recommendation with rationale

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/comprehensive-code-review-mmbizkk8/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/comprehensive-code-review-mmbizkk8' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/comprehensive-code-review-mmbizkk8/download' --output '.skill-downloads/comprehensive-code-review-mmbizkk8/SKILL.md.part' && mv '.skill-downloads/comprehensive-code-review-mmbizkk8/SKILL.md.part' '.skill-downloads/comprehensive-code-review-mmbizkk8/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

This file does not provide a usable name/description header for this native procedure. It remains available to download and inspect; use the manual method below.

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/comprehensive-code-review-mmbizkk8/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
