+ NAME
++ code-review-skill — A comprehensive, modular code review skill for Claude Code +
+SYNOPSIS
++Use code-review-skill to review this PR +Use code-review-skill to review this <component> +Use code-review-skill for [security | performance | architecture] review+
DESCRIPTION
+A production-grade code review skill. It transforms AI-assisted code review from vague suggestions into a structured, consistent, expert-level collaborative process.
+Core is only ~190 lines; the full 16,000+ lines of language guides load on demand. Covers 20+ mainstream languages and frameworks — progressive loading, zero overhead.
+Every finding carries an explicit severity label. Every review proceeds through four phases: PR context · high-level assessment · line-by-line analysis · summary & decision.

-
+
- 1. context gathering — 2-3 min +
- Read the PR description and linked issues, assess scope, check CI status, understand the business intent. +
- 2. high-level review — 5-10 min +
- Evaluate architectural fit, performance impact, file organization, test strategy. See the whole first. +
- 3. line-by-line analysis — 10-20 min +
- Logic correctness · security · performance · maintainability · edge cases. One by one. +
- 4. summary & decision — 2-3 min +
- Summarize findings, name what was done well, deliver approve / comment / request-changes. +
SEVERITY
+-
+
- + ● [blocking] + must fix — resolve before merge; security / correctness / serious logic + +
- + ● [important] + should fix — strongly recommended; discuss if you disagree + +
- + ● [nit] + nice to have — style or preference; non-blocking + +
- + ● [suggestion] + alternative — worth considering; author decides + +
- + ● [learning] + educational — no action needed; share knowledge + +
- + ● [praise] + good work — say it out loud when you see it + +
