Claude Code in Action 深度导读

# CLAUDE.md

## Project Overview
E-commerce platform (Next.js 14 + tRPC + Prisma + PostgreSQL)

## Commands
- Build: `pnpm build`
- Test: `pnpm test`
- Lint: `pnpm lint`

## Code Style
- Use TypeScript strict mode
- Prefer named exports over default exports
- Error handling: use Result type, never throw in business logic
- Tests: co-locate with source files (*.test.ts)

## Architecture Decisions
- Server Components by default; Client Components only for interactivity
- API routes via tRPC; no REST endpoints
- Database migrations via Prisma; never modify schema manually

# .claude/commands/review.md

Review the staged changes for:
1. Logic errors and edge cases
2. Security vulnerabilities (SQL injection, XSS, auth bypass)
3. Performance issues (N+1 queries, unnecessary re-renders)
4. Missing test coverage for new code paths

Output format:
- CRITICAL: Must fix before merge
- WARNING: Should fix, create issue if not now
- NOTE: Nice-to-have improvements

# 效果：每次 Claude 编辑文件后，自动运行 ESLint 修复
# 如果 lint 失败，Claude 会看到错误并自行修复
