What it does

Migrate To Shoehorn is an agent skill from vinvcn/mattpocock-skills-zh-CN. 将测试文件从 as 类型断言迁移到 @total-typescript/shoehorn。适用于用户提到 shoehorn、想替换测试中的 as，或需要局部测试数据时。

Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It works with TypeScript. The repository describes itself as: 这是 mattpocock/skills 的简体中文本地化版本。 The licence is MIT.

Example prompts

  • “/migrate-to-shoehorn”

Requirements

  • Node.js

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. Gather requirements - 询问用户
  2. Install and migrate

What it can do on your machine

Read from SKILL.md and the folder at commit bf98e53. 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 603 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 132 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~27
When it runs · the whole SKILL.md, loaded when a task matches
~603

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。适用于用户提到 shoehorn、想替换测试中的 `as`，或需要局部测试数据时。

迁移到 Shoehorn

为什么用 shoehorn？

shoehorn 允许你在 tests 中传入 partial data，同时保持 TypeScript 满意。它用 type-safe alternatives 替换 as assertions。

只用于 test code。 永远不要在 production code 中使用 shoehorn。

Tests 中 as 的问题：

  • 经过训练，不去使用它
  • 必须手动指定 target type
  • 对故意错误的数据需要 double-as（as unknown as Type）

安装

bash
npm i @total-typescript/shoehorn

迁移模式

只需要少数属性的大型 objects

Before:

ts
type Request = {
  body: { id: string };
  headers: Record<string, string>;
  cookies: Record<string, string>;
  // ...20 more properties
};

it("gets user by id", () => {
  // Only care about body.id but must fake entire Request
  getUser({
    body: { id: "123" },
    headers: {},
    cookies: {},
    // ...fake all 20 properties
  });
});

After:

ts
import { fromPartial } from "@total-typescript/shoehorn";

it("gets user by id", () => {
  getUser(
    fromPartial({
      body: { id: "123" },
    }),
  );
});
as Type → fromPartial()

Before:

ts
getUser({ body: { id: "123" } } as Request);

After:

ts
import { fromPartial } from "@total-typescript/shoehorn";

getUser(fromPartial({ body: { id: "123" } }));
as unknown as Type → fromAny()

Before:

ts
getUser({ body: { id: 123 } } as unknown as Request); // wrong type on purpose

After:

ts
import { fromAny } from "@total-typescript/shoehorn";

getUser(fromAny({ body: { id: 123 } }));

何时使用哪一个

FunctionUse case
fromPartial()传入仍能 type-check 的 partial data
fromAny()传入故意错误的数据（保留 autocomplete）
fromExact()强制 full object（之后可换成 fromPartial）

工作流

  1. Gather requirements - 询问用户：

    • 哪些 test files 中的 as assertions 造成问题？
    • 是否在处理大型 objects，但只关心部分 properties？
    • 是否需要传入故意错误的数据来测试 error paths？

  2. Install and migrate：

    • Install: npm i @total-typescript/shoehorn
    • 查找 test files 中的 as assertions: grep -r " as [A-Z]" --include="*.test.ts" --include="*.spec.ts"
    • 用 fromPartial() 替换 as Type
    • 用 fromAny() 替换 as unknown as Type
    • 添加来自 @total-typescript/shoehorn 的 imports
    • 运行 type check 验证
