UX Copywriting Standards

Professional, concise, and friendly copy guidelines for user interface text.

When to Activate

Use this skill when the user:

• Asks "write an error message" or "what should the button say?"
• Mentions "toast message", "success text", or "warning copy"
• Needs to "format a number" or "write tooltip text"
• Wants to "improve this message" or "make it more user-friendly"

Tone Principles

1. Professional (专业)

• State facts clearly
• Avoid casual expressions
• Use industry terminology correctly

✅ Good: "数据加载完成，共加载 5,123 条记录" ❌ Bad: "哇！数据超多的！"

2. Concise (简洁)

• Use 3-10 words when possible
• Remove unnecessary adjectives
• Get to the point

✅ Good: "刷新成功" (3 words) ❌ Bad: "您的数据刷新操作已经成功完成了" (冗长)

3. Friendly (友好)

• Be polite
• Offer solutions
• Don't blame users

✅ Good: "未找到匹配数据，请调整筛选条件" ❌ Bad: "没数据"

Copy Templates

Success Messages

Implementation:

export const SUCCESS_MESSAGES = {
  dataRefresh: (date) => `数据刷新成功，最新日期: ${date}`,
  filterApply: (count) => `筛选已应用，找到 ${count.toLocaleString()} 条记录`,
  export: (filename) => `${filename} 已下载`,
  settingsSaved: () => '设置已保存'
}

Error Messages

Formula: Problem + Solution

Implementation:

export const ERROR_MESSAGES = {
  network: {
    title: '无法连接服务器',
    message: '请检查网络连接，或稍后重试'
  },
  dataLoad: (reason) => ({
    title: '数据加载失败',
    message: reason || '请刷新页面或联系管理员'
  }),
  invalidFile: {
    title: '不支持的文件格式',
    message: '请上传 .xlsx 或 .csv 文件'
  }
}

Warning Messages

Button Labels

Number Formatting

Formatter Functions

export const formatters = {
  // Premium formatting
  premium(value) {
    if (value == null) return '-'
    const abs = Math.abs(value)
    const sign = value < 0 ? '-' : ''

    if (abs >= 10000) {
      return `${sign}${(abs / 10000).toFixed(1)} 万元`
    }
    return `${sign}${abs.toLocaleString('zh-CN')} 元`
  },

  // Percentage
  percentage(value, decimals = 1) {
    if (value == null) return '-'
    return `${(value * 100).toFixed(decimals)}%`
  },

  // Count
  count(value) {
    if (value == null) return '-'
    return `${value.toLocaleString('zh-CN')} 条`
  },

  // Date
  date(value, format = 'short') {
    if (!value) return '-'
    const d = new Date(value)
    if (format === 'short') {
      return d.toISOString().split('T')[0]  // YYYY-MM-DD
    }
    return `${d.getFullYear()}年${String(d.getMonth()+1).padStart(2,'0')}月${String(d.getDate()).padStart(2,'0')}日`
  }
}

Usage Examples

formatters.premium(125420)          // "12.5 万元"
formatters.premium(-5000)           // "-5,000 元"
formatters.percentage(0.235)        // "23.5%"
formatters.count(5123)              // "5,123 条"
formatters.date('2025-11-09')       // "2025-11-09"
formatters.date('2025-11-09', 'long') // "2025年11月09日"
