工具从 JSON 示例推断结构并生成代码。使用前请检查可选字段、嵌套对象、命名和类型。
这是起始代码，请根据 API 契约检查字段、日期和空值。
API 响应、配置文件、日志——JSON 是开发者读得最多的数据格式。然而一个逗号或引号就可能引发 “Unexpected token” 错误。下面介绍如何快速找到原因。
JSON(JavaScript Object Notation)是由 RFC 8259 和 ECMA-404 标准化的文本格式。它源自 JavaScript，如今几乎所有语言都支持。值的类型只有六种：字符串、数字、布尔值(true/false)、null、数组和对象。
{
"id": 1024,
"name": "AIBIZAP",
"active": true,
"tags": ["tools", "guides"],
"owner": null

You are an experienced full-stack web developer. Build a web tool called "JSON 类生成器" that meets the requirements below.
## Goal
Build a tool that generates C#, Java, Python and TypeScript model classes from a JSON sample.
## Core features
- Choose C#, Java, Python dataclasses or TypeScript interfaces
- Create separate classes for nested objects
- Infer array element types
- Set the root class name
- Apply each language's naming conventions
## Inputs
- JSON sample
- Target language and root class name
## Outputs
- Generated code
- Summary of inferred types
## Edge cases and handling rules
- Treat null values as nullable types
- Merge differing keys across array elements
- Handle keys that clash with reserved words
- Keep original names for keys with digits or hyphens via serialization attributes
## Implementation requirements
- Build it as a single page (HTML, CSS, JavaScript) that runs entirely in the browser, and never send the user's input to a server.
- Make the UI responsive and easy to use on mobile; label every input and keep everything keyboard accessible.
- Add a Copy button for results and show clear, friendly error messages for invalid input.
- Keep the core logic in functions separate from the UI so it can be unit-tested.
## Definition of done (test cases)
- {"id":1,"name":"a"} gives int Id and string Name in C#
- Nested objects become separate classes
- Empty arrays become lists of object/any
First outline your implementation plan in at most five lines, then write the complete code, and finally explain how to check the test cases above.在 Claude Code 等 AI 编程助手中保存为 .claude/skills/build-json-class-generator/SKILL.md，以后开发或修改此工具时可重复使用。

# Build: JSON 类生成器
## Goal
Build a tool that generates C#, Java, Python and TypeScript model classes from a JSON sample.
## Workflow
1. Review the required features, inputs and outputs below and ask about anything missing first.
2. Implement the core logic as pure functions separate from the UI.
3. Check the logic against the test cases in the verification list.
4. Build a responsive UI with an input form, a result area and a Copy button.
5. Reproduce each edge case listed under Rules and refine the error messages.
## Core features
- Choose C#, Java, Python dataclasses or TypeScript interfaces
- Create separate classes for nested objects
- Infer array element types
- Set the root class name

- Keep original names for keys with digits or hyphens via serialization attributes
- Build it as a single page (HTML, CSS, JavaScript) that runs entirely in the browser, and never send the user's input to a server.
## Verification
- [ ] {"id":1,"name":"a"} gives int Id and string Name in C#
- [ ] Nested objects become separate classes
- [ ] Empty arrays become lists of object/any
