alibaba/hooks is a TypeScript library of React Hooks, including basic utilities and Hooks shaped by common application development needs. React developers use it in applications that may also require server-side rendering and predictable static types. The catalogue entries provide rules and instructions for using the library.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00714 | $0.00714 |
| Opus 5.5 | $0.00286 | $0.00286 |
| Sonnet 5.5 | $0.00143 | $0.00143 |
| Haiku 4.5 | $0.00071 | $0.00071 |
Grade A, and why
typescript scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
TypeScript 规范
基本原则
- 所有组件和函数必须提供准确的类型定义
- 尽量避免使用
any类型，尽可能精确地定义类型 - 使用接口而非类型别名定义对象结构
- 导出所有公共接口类型，方便用户使用
- 严格遵循 TypeScript 类型设计原则，确保类型安全
- 确保编译无任何类型错误或警告
hook 类型定义
- 复杂的数据结构应拆分为多个接口定义
- 所有函数类型应明确定义参数和返回值
泛型使用
- 适当使用泛型增强类型灵活性
- 为泛型参数提供合理的默认类型和约束
- 避免过度使用泛型导致类型复杂化
- 在泛型参数上应用限制条件（constraints）确保类型安全
- 为复杂泛型提供类型别名以提高可读性
类型合并与扩展
- 使用交叉类型（&）合并多个类型
- 使用 Partial、Pick<T, K>、Omit<T, K> 等工具类型修改现有类型
- 扩展原生 DOM 元素属性时，继承相应的内置类型
- 使用 type 定义联合类型和交叉类型
- 优先使用自带的工具类型，避免重复定义
枚举和常量
- 使用字面量联合类型定义有限的选项集合
- 为复杂的枚举值提供类型守卫函数
- 避免使用
enum，优先使用联合类型和as const - 对于关键常量，使用
as const断言确保类型严格 - 为联合类型中的每个值提供适当的注释
类型推断与断言
- 尽可能依赖 TypeScript 的类型推断
- 只在必要时使用类型断言（as）
- 使用类型守卫函数进行运行时类型检查
- 尽量避免使用非空断言操作符（!）
- 使用
instanceof和typeof进行类型守卫 - 为自定义类型创建类型谓词（type predicates）函数
JSDoc 注释
- 为复杂的类型、函数、hook 添加 JSDoc 注释
- 使用
@deprecated标记已废弃的 API - 在注释中提供使用示例
- 说明参数和返回值的含义与约束
- 在 interface 和重要类型定义上添加文档注释
类型兼容性
- 确保类型定义兼容不同版本的 React
- 避免使用实验性或不稳定的 TypeScript 特性
- 为第三方库未提供的类型编写声明文件
- 使用条件类型处理复杂的类型逻辑
- 验证类型在不同 TypeScript 版本下的兼容性
严格使用 TypeScript 类型
- 导出组件类型和接口
- 避免使用 any，优先使用 unknown
- 组件 Props 使用 interface 定义
- 使用明确的命名约定
- 合理使用泛型提高复用性
- 导出类型时使用 export type
- 组件属性使用 JSDoc 注释说明用途
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

typescript is a cursor rule published in the GitHub repository alibaba/hooks (14,973 stars, last pushed 9d ago), licensed MIT. It adds 714 tokens to every session, about $0.0029 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
