\n\n---\n\n\n\n## English\n\n### What is this?\n\n**Code Review Skill** is a production-ready skill for [Claude Code](https://claude.ai/code) that transforms AI-assisted code review from vague suggestions into a **structured, consistent, and expert-level** process.\n\nIt covers **20+ languages and frameworks** with over **21,000 lines** of carefully curated review guidelines — loaded progressively to minimize context window usage.\n\n---\n\n### ✨ Key Features\n\n- **Progressive Disclosure** — Core skill is ~220 lines; language guides (~200–1,100 lines each) load only when needed.\n- **Four-Phase Review Process** — Structured workflow from understanding scope to delivering clear feedback.\n- **Severity Labeling** — Every finding is categorized: `blocking` · `important` · `nit` · `suggestion` · `learning` · `praise`\n- **Security-First** — Dedicated security checklists per language ecosystem.\n- **Collaborative Tone** — Questions over commands, suggestions over mandates.\n- **Automation Awareness** — Clearly separates what human review should catch vs. what linters handle.\n\n---\n\n### 🌐 Supported Languages & Frameworks\n\n\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n
