What it does
Migrate To Shoehorn is an agent skill from devcxl/mattpocock-skills-zh. 将测试文件从 as 类型断言迁移到 @total-typescript/shoehorn。当用户提到 shoehorn、想要在测试中替换 as、或需要部分测试数据时使用。
Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Development. It works with TypeScript. The repository describes itself as: Matt Pocock 技能集的中文翻译版 — 地道中文，原汁原味的技术术语。基于 mattpocock/skills 复刻。每日中午12点钟同步. The licence is MIT.
When your agent uses it
- Development work in your project
Example prompts
- “/migrate-to-shoehorn”
Requirements
- Node.js
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- 收集需求 — 询问用户
- 安装并迁移
What it can do on your machine
Read from SKILL.md and the folder at commit 05f3ef5. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Migrate To Shoehorn loads about 522 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 88 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- 将测试文件从 `as` 类型断言迁移到 @total-typescript/shoehorn。当用户提到 shoehorn、想要在测试中替换 `as`、或需要部分测试数据时使用。
迁移到 Shoehorn
为什么使用 shoehorn？
shoehorn 让你在测试中传递部分数据，同时保持 TypeScript 类型正确。它用类型安全的替代方案取代了 as 断言。
仅限测试代码。 切勿在生产代码中使用 shoehorn。
as 在测试中的问题：
- 习惯上被训练不要使用它
- 必须手动指定目标类型
- 双重
as（as unknown as Type）用于传递故意错误的数据
安装
npm i @total-typescript/shoehorn迁移模式
大型对象，只用到少数属性
迁移前：
type Request = {
body: { id: string };
headers: Record<string, string>;
cookies: Record<string, string>;
// ...还有 20 个属性
};
it("gets user by id", () => {
// 只关心 body.id，但必须伪造整个 Request
getUser({
body: { id: "123" },
headers: {},
cookies: {},
// ...伪造所有 20 个属性
});
});迁移后：
import { fromPartial } from "@total-typescript/shoehorn";
it("gets user by id", () => {
getUser(
fromPartial({
body: { id: "123" },
}),
);
});as Type → fromPartial()
迁移前：
getUser({ body: { id: "123" } } as Request);迁移后：
import { fromPartial } from "@total-typescript/shoehorn";
getUser(fromPartial({ body: { id: "123" } }));as unknown as Type → fromAny()
迁移前：
getUser({ body: { id: 123 } } as unknown as Request); // 故意传错类型迁移后：
import { fromAny } from "@total-typescript/shoehorn";
getUser(fromAny({ body: { id: 123 } }));各函数的适用场景
| 函数 | 使用场景 |
|---|---|
fromPartial() | 传递部分数据，仍能通过类型检查 |
fromAny() | 传递故意错误的数据（保留自动补全） |
fromExact() | 强制传入完整对象（后续可替换为 fromPartial） |
工作流程
收集需求 — 询问用户：
- 哪些测试文件中的
as断言造成了问题？ - 是否涉及大型对象，只有部分属性是重要的？
- 是否需要传递故意错误的数据用于错误测试？
- 哪些测试文件中的
安装并迁移：
- 安装：
npm i @total-typescript/shoehorn - 查找含有
as断言的测试文件：grep -r " as [A-Z]" --include="*.test.ts" --include="*.spec.ts" - 将
as Type替换为fromPartial() - 将
as unknown as Type替换为fromAny() - 从
@total-typescript/shoehorn添加 import - 运行类型检查以验证
