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 | $0.00714 | $0.00714 |
| Opus 5 | $0.00357 | $0.00357 |
| Sonnet 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 today.
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 (14,977 stars, last pushed today), licensed MIT. It adds 714 tokens to every session, about $0.0036 per session on Opus 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.
