SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill removes vague and overly polite code feedback by providing concise senior-engineer reviews focused on concrete issues that matter before shipping code.

Core Features & Use Cases

Diff-Based Code Review: Reviews git changes, branch diffs, recent edits, or specified files to identify correctness, security, reliability, and maintainability problems.
Actionable Issue Reporting: Produces severity-based verdicts with file and line references so another coding agent can address the findings directly.
Use Case: Before merging a pull request, ask Marko to inspect the current changes and receive a terse review highlighting the most important defects without unnecessary praise or suggested fixes.

Quick Start

Ask Marko to review the current code changes and identify the problems that need attention.

FAQPage Schema

How do I get an automated code review for a git diff before merging?▼

An automated code review for a git diff analyzes branch changes and recent edits to identify concrete defects. It generates severity-based verdicts with specific file and line references, highlighting correctness, security, and reliability problems without providing implementation fixes.

Can I use a coding agent to find bugs in recent source file edits?▼

Yes, you can use a coding agent to find bugs in recent source file edits by applying senior-review criteria. The process targets specified files and recent edits to anchor issues by file and line, producing actionable feedback focused solely on defects that matter before delivery.

What is a ruthless code review and how does it differ from standard feedback?▼

A ruthless code review is a concise senior-engineer feedback mechanism that removes vague and overly polite language. It focuses strictly on severity-based issue reporting and concrete risks without unnecessary praise or suggested implementation fixes.

Does automated code review work with Claude Code or Codex workflows?▼

Automated code review integrates into Claude Code and Codex workflows by analyzing git changes and targeted source files. It produces actionable issue reports designed so another coding agent can directly address the identified findings within the engineering workflow.

Will a code review Skill provide implementation fixes for detected defects?▼

No, a code review Skill will not provide implementation fixes for detected defects. It applies senior-review criteria to generate concise verdicts and anchor issues by file and line, intentionally leaving the actual code modifications to another coding agent.
