Pre Push

Pre-Push

Overview

One skill for everything before pushing: review code → generate PR description → confirm → push → save checkpoint.

团队架构参考: https://lucian-why.github.io/team-skills/team-architecture.html

Core principle: Check checkpoint → AI reviews code → human reviews architecture → generate description → push → save checkpoint.

Announce at start: "I'm using the pre-push skill to review and prepare PR."

When to Use

• Before git push on a feature/fix branch
• When you finish a feature or fix and want to create a PR
• Triggers automatically if you say "推送" / "提 PR" / "push"

Checkpoint System

Purpose: Avoid running the same skill twice on the same state.

Checkpoint file: .claude/.skill-checkpoints (gitignored)

Format: skill_name|branch_name|timestamp|commit_hash

Step 0: Check Checkpoint

BRANCH=$(git branch --show-current)
COMMIT=$(git rev-parse --short HEAD)

if [ -f .claude/.skill-checkpoints ]; then
  grep "pre-push|${BRANCH}||" .claude/.skill-checkpoints | tail -1
fi

If checkpoint exists and commit matches:

✅ Pre-push already completed for branch 'feature/login' (commit abc1234)
   Created at: 2026-05-15 10:30

   Options:
   1. Skip (PR already exists)
   2. Re-run (new commits since last run)
   3. Edit existing PR description

• "Skip" → done
• "Re-run" → continue to Step 1
• "Edit" → jump to Step 4 with existing description

If no checkpoint or commit changed: → Continue to Step 1

The Process

Step 1: Gather Context

git branch --show-current
git merge-base HEAD main 2>/dev/null || git merge-base HEAD master 2>/dev/null
git log --oneline <base>..HEAD
git diff --stat <base>..HEAD
git diff <base>..HEAD

For large diffs (>500 lines), focus on --stat and --name-status, read key files directly.

Step 2: AI Code Review

AI runs a thorough code review and generates a structured report.

AI checks (代码细节):

• Syntax errors, typos
• Edge cases, null handling
• Security vulnerabilities (SQL injection, XSS, hardcoded secrets)
• Code style consistency
• Hallucinated APIs (functions that don't exist)
• Test coverage
• Dependency sanity

Output format:

## 🔍 AI Code Review Report

### ✅ 通过
- 安全：无 SQL 注入、XSS 风险
- 边界：空值处理完整
- 风格：与项目一致

### ⚠️ 需要人确认
- `auth.service.ts:42` — 这里的重试逻辑，3 次够吗？会不会打爆下游？
- `api/users.ts:18` — 返回了全量用户数据，需要分页吗？

### ❌ 必须修复
- `config/database.ts:7` — 密码硬编码在代码里

Rules:

• ✅ 通过的只列一行总结，不展开
• ⚠️ 需要确认的，指出具体文件:行号 + 问题 + 建议
• ❌ 必须修复的，给出修复建议
• 不要啰嗦，每个问题最多两句话

Step 3: Human Reviews Architecture

Present the review report to the human, then ask only about architecture:

AI 审完了代码细节，上面是报告。

现在需要你确认架构层面：
1. 这个功能的设计模式对不对？
2. 模块间耦合合理吗？
3. 有没有性能瓶颈风险？

（不懂代码没关系，你审的是"这样做对不对"，不是"写得对不对"）

Rules:

• Human doesn't need to read code line by line
• Focus on: design decisions, business logic, maintainability
• If human says "looks good" → proceed
• If human has concerns → address them before proceeding

Step 4: Fill Information Gaps

Check if PR description needs more context:

Max 2-3 questions. If diff is self-explanatory, skip.

Step 5: Generate PR Description

Template:

## 变更概述
<1-2 sentences: what this PR does and why>

## 具体改动
- <change 1: what and where>
- <change 2: what and where>

## 影响范围
- <affected module/feature>

## 测试验证
- [ ] <how this was tested>

## 注意事项
- <breaking changes, migration steps, things reviewers should pay attention to>

Rules:

• Title: conventional commits (feat:, fix:, refactor:, docs:, chore:, perf:, test:)
• Title: Chinese or English, under 72 chars
• Be specific: "修复登录页密码输入框的白屏问题" not "修复 bug"
• Omit 注意事项 if nothing notable
• Write "待补充" in 测试验证 if no tests were run

Step 6: Present for Confirmation

---
**Title:** feat: 用户登录模块重构

## 变更概述
重构用户登录模块，将认证逻辑从 Controller 抽取到独立的 AuthService。

## 具体改动
- 新增 `src/services/auth.service.ts`，封装登录/注册/token 刷新逻辑
- 修改 `src/controllers/user.controller.ts`，调用 AuthService 替代直接数据库操作

## 影响范围
- 用户登录/注册功能
- Token 刷新机制

## 测试验证
- [x] AuthService 单元测试通过
- [x] 手动测试登录/注册流程正常
---

Options:
1. Accept and push + create PR
2. Edit description (tell me what to change)
3. I'll write it myself

Step 7: Push and Create PR

git push -u origin $(git branch --show-current)
gh pr create --title "<title>" --body "$(cat <<'EOF'
<confirmed PR description>
EOF
)"

Step 8: Save Checkpoint

BRANCH=$(git branch --show-current)
COMMIT=$(git rev-parse --short HEAD)
mkdir -p .claude
echo "pre-push|${BRANCH}|$(date -Iseconds)|${COMMIT}" >> .claude/.skill-checkpoints

✅ PR created: https://github.com/xxx/xxx/pull/123
📌 Checkpoint saved — same branch + same commit won't re-run. New commits will auto re-run.

Quick Reference

Tips

• Review 报告要精炼: ✅ 一行总结，⚠️ 和 ❌ 指出文件:行号
• 人不需要逐行看代码: 审架构决策，不审语法细节
• Checkpoint = 幂等: 同分支+同 commit = 跳过，新 commit = 重跑
• Branch name helps: fix/login-white-screen → fix, feat/user-auth → feat

Common Mistakes

AI review 太啰嗦

• Bad: 每个文件写三段分析
• Good: ✅ 通过列一行，⚠️ 和 ❌ 直接指出问题

人去逐行看代码

• Bad: 人花 30 分钟看每一行
• Good: 人只看 AI 报告里的 ⚠️ 部分，确认架构决策

PR 描述太笼统

• Bad: "修改了一些文件"
• Good: "重构 AuthService，将 token 刷新逻辑从 Controller 抽取为独立方法"
