Review Principles

评审原则

  • Pull ALL existing comments before reviewing
  • Don't repeat previously given feedback
  • Focus on new changes in incremental reviews
  • Be constructive and specific
  • Provide code examples for improvements
  • Rate issues by severity (Critical, Major, Minor, Suggestion)
  • Use professional emoji sparingly (✅, ⚠️, 🚨, 💡)
  • Keep review concise but thorough
  • Format with clear sections and bullet points
  • 评审前先查看所有现有评论
  • 不要重复已给出的反馈
  • 增量评审时仅关注新变更
  • 反馈需具有建设性且具体
  • 提供改进的代码示例
  • 按严重程度对问题评级（Critical：严重、Major：重要、Minor：次要、Suggestion：建议）
  • 谨慎使用专业表情符号（✅, ⚠️, 🚨, 💡）
  • 评审需简洁但详尽
  • 使用清晰的章节和项目符号格式

Parameters

参数

  • pr_number
    : PR number to review (required)
  • incremental
    : true for reviewing only latest changes, false for full review (default: false)
  • pr_number
    : 待评审的PR编号（必填）
  • incremental
    : 为true时仅评审最新变更，为false时进行完整评审（默认：false）

Step 1: Gather Context

步骤1：收集上下文

Always pull existing comments first to avoid duplication:
bash
undefined
请始终先获取所有现有评论以避免重复：
bash
undefined

Get PR info

获取PR信息

gh pr view <pr_number> --json number,title,body,files
gh pr view <pr_number> --json number,title,body,files

Pull ALL comments (always do this first)

获取所有评论（务必先执行此操作）

gh pr view <pr_number> --comments gh api repos/{owner}/{repo}/pulls/<pr_number>/comments
gh pr view <pr_number> --comments gh api repos/{owner}/{repo}/pulls/<pr_number>/comments

Get appropriate diff

获取对应的差异

if incremental: git diff HEAD~1..HEAD # Latest commit only else: gh pr diff <pr_number> # Full PR diff
undefined
if incremental: git diff HEAD~1..HEAD # 仅最新提交 else: gh pr diff <pr_number> # 完整PR差异
undefined

Step 2: Analyze Changes

步骤2：分析变更

  • For incremental: Focus ONLY on new changes
  • For full: Consider entire PR but acknowledge existing comments
  • Check against review checklist
  • Note resolved vs new issues
  • Identify patterns and systemic issues
  • 增量评审：仅关注新变更
  • 完整评审：考虑整个PR，但需注意现有评论
  • 对照评审检查清单进行检查
  • 记录已解决的问题与新问题
  • 识别模式性与系统性问题

Step 3: Post Review

步骤3：发布评审结果

Use appropriate template based on review type:
根据评审类型使用对应的模板：

增量评审模板

bash
gh pr comment <pr_number> --body "$(cat <<'EOF'
