What Field Mapping Safety does

Field Mapping Safety prevents mistakes when refactoring table columns, enum maps, and type conversions. It is used to verify real field names and complete mappings before changing code.

Field Mapping Safety is cataloged under Quality on DirSkills. Field Mapping Safety comes from a repository tagged antigravity, claude-code, codex, cursor and gemini-cli.

Documentation

README

字段映射安全规范

触发场景

  • 重构表格列定义（dataIndex、columns）
  • 重构枚举类型映射（typeMap、statusMap）
  • 重构数据转换逻辑（render 函数、formatter）
  • 类型定义中有多个相似字段（changedAt vs createdAt）

核心原则

不要根据类型定义推测字段名，必须查看原始代码的实际使用

检查清单

1. 字段名验证

  • 查看原始代码的 dataIndex
  • 查看后端 API 返回的实际字段名
  • 优先使用必填字段，避免可选字段
  • 注意字段名的细微差异（changedAt vs createdAt、changeType vs operationType）

2. 枚举映射验证

  • 对照原始代码，逐个检查枚举值
  • 确保映射完整（不遗漏任何枚举值）
  • 检查枚举值的拼写（UPLOAD vs Upload）
  • 检查枚举值的颜色、文本是否一致

3. 运行时测试

  • TypeScript 类型检查通过（必要但不充分）
  • 在实际环境中测试功能
  • 检查是否显示 "Invalid Date"、"undefined"、空白
  • 检查枚举值是否都有对应的映射

常见陷阱

陷阱 1: 类型定义有歧义

场景：类型定义中有多个相似字段

Api Proxy Safety

Api Proxy Safety defines safe keyword matching for gateways, proxies, WAFs, and CDNs so normal content is not misclassified as an error. It is used when implementing heuristic checks for response bodies, status codes, and error schemas.
