Claude Code 斜杠命令、快捷键与 CLI 完全参考手册

# 先检查上下文使用情况
/context

# 如果上下文快满了，带聚焦指令压缩
/compact retain the authentication flow and test results

# 如果要完全切换任务，清除所有内容
/clear

# 快速会话健康检查
/cost          # 我花了多少钱？
/context       # 上下文窗口满了多少？
/usage         # 我快到速率限制了吗？

# 用 Sonnet 开始会话（默认，更便宜）
/model sonnet

# 遇到棘手 bug？切换到 Opus
/model opus

# 难点处理完了，切回来
/model sonnet

# 安装 GitHub CLI
brew install gh

# 认证
gh auth login

# 现在可以在 Claude Code 中使用 PR 命令了
/review 42        # 审查 PR #42
/pr-comments      # 显示当前分支 PR 的评论
/security-review  # 对未提交更改进行安全审计

! npm test                # 运行测试，输出进入上下文
! git log --oneline -5    # 检查最近的提交
! cat .env.example        # 显示文件内容

# 生成 API 文档并保存到文件
claude -p "Generate API documentation for src/api/" --output-format text > api-docs.md

# 以 JSON 格式获取结构化分析
claude -p "Analyze the error handling in this project" --output-format json | jq '.result'

# 限制耗费较高的操作的花费
claude -p --max-budget-usd 2.00 --max-turns 5 "Refactor the auth module"

# 通过管道传入内容进行分析
cat error.log | claude -p "What caused this crash?"

# CI/CD：带预算上限检查代码质量
claude -p --max-budget-usd 1.00 --output-format json \
  "Review the last commit for security issues" | jq '.result'

# 只允许读取操作和 git 命令
claude -p --allowedTools "Bash(git log:*)" "Bash(git diff:*)" "Read" "Grep" "Glob" \
  "Generate a code review for the last 3 commits"

# 添加项目特定规则
claude --append-system-prompt "Always use TypeScript. Never use any. Include JSDoc comments."

# 从文件加载规则以保持团队一致性
claude --append-system-prompt-file ./team-rules.txt

# 项目级技能（通过 Git 与团队共享）
mkdir -p .claude/skills/deploy

# 个人技能（在你所有项目中可用）
mkdir -p ~/.claude/skills/deploy

# Deployment Workflow

## Pre-deployment Checks
1. Run the full test suite: `npm test`
2. Check for uncommitted changes: `git status`
3. Verify you're on the correct branch

## Deploy Steps
1. Build the production bundle: `npm run build`
2. Run database migrations if needed
3. Deploy using: `./scripts/deploy.sh <environment>`
4. Verify the deployment health check

## Post-deployment
1. Monitor error rates for 15 minutes
2. Run smoke tests against the deployed environment
3. Update the deployment log

# 手动调用
/deploy

# 或者直接描述你想做什么——Claude 会自动检测到对应技能
"Deploy the latest changes to staging"

# 完成一个子任务后，在开始下一个前压缩

# 在复杂操作前腾出空间
