### Fail loudly on invalid configuration

If configuration refers to an unregistered LLM provider route or another nonexistent resource, fail early instead of silently skipping it:

A tool is a capability the model can call. This guide builds one with `defineTool`.
|
||||
This tutorial adds a `greet` tool to the Web UI. Complete [Your first plugin](./) first and keep its `scratch-plugin` directory.
|
||||
|
||||
## Minimal example
|
||||
## Create the tool plugin

||||
|
||||
Replace `scratch-plugin/src/my-plugin.ts` with:

||||

||||
```ts
|
||||

|
||||

export const name = 'my-tool'

|

return `Hello, ${args.name}!`
|
||||
},
|
||||
}))
|
||||
}
|
||||
```
|
||||
|
||||
## Parameter definitions
|
||||
`inject` makes Cordis wait for the tool registry. `defineTool` infers and validates `args` from `parameters`; `execute` returns the canonical value declared by `output.schema`, and `output.render` converts that value to model-facing content.
|
||||
|
||||
`parameters` uses a compact format that the framework converts to the JSON Schema sent to the model.
|
||||
## Run and call the tool
|
||||
|
||||
### Primitive types
|
||||
Restart the development command if it is not running:
|
||||
|
||||
```ts
|
||||
export const parameters = {
|
||||
path: { type: 'string', required: true },
|
||||
limit: { type: 'integer' },
|
||||
recursive: { type: 'boolean' },
|
||||
parent: { type: 'null' },
|
||||
}
|
||||
// Inferred type: { path: string; limit?: number; recursive?: boolean; parent?: null }
|
||||
```sh
|
||||
pnpm run dsh web --config ./scratch-plugin/cordis.yml
|
||||
```
|
||||
|
||||
### Enums
|
||||
|
||||
```ts
|
||||
export const parameters = {
|
||||
mode: { type: 'string', required: true, enum: ['read', 'write', 'append'] },
|
||||
}
|
||||
// Inferred type: { mode: 'read' | 'write' | 'append' }
|
||||
```
|
||||
|
||||
### Nested objects
|
||||
|
||||
```ts
|
||||
export const parameters = {
|
||||
options: {
|
||||
type: 'object',
|
||||
additionalProperties: true,
|
||||
properties: {
|
||||
timeout: { type: 'number' },
|
||||
retries: { type: 'number' },
|
||||
},
|
||||
},
|
||||
}
|
||||
// The declared fields are inferred; additional JSON-valued keys are allowed.
|
||||
```
|
||||
|
||||
### Arrays
|
||||
|
||||
```ts
|
||||
export const parameters = {
|
||||
tags: {
|
||||
type: 'array',
|
||||
items: { type: 'string' },
|
||||
},
|
||||
}
|
||||
// Inferred type: { tags?: string[] }
|
||||
```
|
||||
|
||||
### Property fields
|
||||
|
||||
| Field | Type | Meaning |
|
||||
|------|------|------|
|
||||
| `type` | `'string' \| 'number' \| 'integer' \| 'boolean' \| 'null' \| 'object' \| 'array' \| 'json'` | Value type; `json` accepts any lossless JSON value |
|
||||
| `required` | `true` | Marks the property required and affects inference |
|
||||
| `description` | `string` | Description sent to the model |
|
||||
| `enum` / `const` | matching scalar values | Allowed literal values, checked at author and runtime boundaries |
|
||||
| `properties` | `ParameterSchemaSpec` | Nested properties for an object |
|
||||
| `additionalProperties` | `true \| false` | Required on every explicit object node |
|
||||
| `items` | `ValueSchemaSpec` | Element schema for an array |
|
||||
| `oneOf` | at least two `ValueSchemaSpec` branches | Requires exactly one matching branch; used instead of `type` |
|
||||
|
||||
The outer `parameters` map is an implicit open object. Explicit nested objects choose their openness; raw JSON Schema registered without `defineTool` keeps JSON Schema's open-by-default behavior.
|
||||
|
||||
## The execute function
|
||||
|
||||
`execute` receives validated, inferred `args` and an `exec` execution context:
|
||||
|
||||
```ts
|
||||
import { defineTool } from '@deepseek-ai/dsh-tools'
|
||||
|
||||
export const tool = defineTool({
|
||||
name: 'example',
|
||||
description: 'Return an example result.',
|
||||
parameters: {},
|
||||
output: {
|
||||
schema: { type: 'string' },
|
||||
render: (_args, value) => [{ type: 'text', text: value }],
|
||||
},
|
||||
async execute(args, exec) {
|
||||
// args: inferred from parameters
|
||||
// exec: ToolExecution context
|
||||
|
||||
// Return the value declared by output.schema.
|
||||
void args
|
||||
void exec
|
||||
return 'result here'
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### Return value
|
||||
|
||||
`execute` returns the lossless JSON value declared by `output.schema`. `output.render(args, value)` separately turns that validated value into the Native/model-facing content:
|
||||
|
||||
```ts ignore-check
|
||||
output: {
|
||||
schema: {
|
||||
type: 'object',
|
||||
additionalProperties: false,
|
||||
properties: {
|
||||
path: { type: 'string', required: true },
|
||||
content: { type: 'string', required: true },
|
||||
},
|
||||
},
|
||||
render: (_args, value) => [{ type: 'text', text: value.content }],
|
||||
},
|
||||
async execute(args) {
|
||||
return { path: args.path, content: await readFile(args.path, 'utf8') }
|
||||
}
|
||||
```
|
||||
|
||||
The canonical value is available to execution-time programmatic callers and is not persisted in `tool/result`; the rendered content and optional `presentationMeta` are the replayable projections. A body value that does not satisfy the schema, or is not lossless JSON, becomes an `INVALID_TOOL_OUTPUT` failure.
|
||||
|
||||
### Argument validation
|
||||
|
||||
Before calling `execute`, `defineTool` validates model-generated arguments. Invalid input raises `ToolArgsError`; the framework turns it into an `isError` result so the model can correct its call.
|
||||
|
||||
Do not repeat type validation inside `execute`.
|
||||
|
||||
## Presentation
|
||||
|
||||
A tool can define transport-neutral presentation methods for terminal and web clients:
|
||||
|
||||
```ts ignore-check
|
||||
defineTool({
|
||||
name: 'bash',
|
||||
// ...
|
||||
output: {
|
||||
schema: { type: 'string' },
|
||||
render: (_args, value) => [{ type: 'text', text: value }],
|
||||
},
|
||||
presentCall(args) {
|
||||
return {
|
||||
card: 'terminal',
|
||||
title: args.command,
|
||||
}
|
||||
},
|
||||
presentResult(args, result) {
|
||||
return {
|
||||
card: 'terminal',
|
||||
output: result.content.map(b => b.type === 'text' ? b.text : '').join(''),
|
||||
}
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
`presentCall` and `presentResult` are **pure functions**. Streaming UI and session replay may call them more than once.
|
||||
|
||||
## Registration and unloading
|
||||
|
||||
`ctx.tools.register()` returns a disposer, but a registration made through `ctx` is already tracked by the framework. Unloading the plugin removes the tool automatically, so the plugin does not call the disposer itself.
|
||||
|
||||
```ts ignore-check
|
||||
// This is sufficient:
|
||||
ctx.tools.register(defineTool({ /* ... */ }))
|
||||
|
||||
// No saved disposer or extra cleanup registration is needed.
|
||||
```
|
||||
|
||||
## Complete example

||||
|
||||

|
||||
|
||||
```ts
|

|

工具是模型可以调用的能力。本文介绍如何用 `defineTool` 编写一个工具。
|
||||
本教程会在 Web UI 中添加一个 `greet` 工具。请先完成[第一个插件](./)，并保留其中的 `scratch-plugin` 目录。
|
||||
|
||||
## 最小示例
|
||||
## 创建工具插件
|
||||
|
||||
将 `scratch-plugin/src/my-plugin.ts` 替换为：
|
||||
|
||||
```ts
|
||||
import type { Context } from 'cordis'
|
||||
import { defineTool } from '@deepseek-ai/dsh-tools'
|
||||
|
||||
export const name = 'my-tool'
|
||||
export const name = 'greet-tool'
|
||||
export const inject = ['tools']
|
||||
|
||||
export function apply(ctx: Context) {
|
||||
@@ -25,221 +27,26 @@ export function apply(ctx: Context) {
|
||||
render: (_args, value) => [{ type: 'text', text: value }],
|
||||
},
|
||||
async execute(args) {
|
||||
// args is inferred as { name: string }.
|
||||
return `Hello, ${args.name}!`
|
||||
},
|
||||
}))
|
||||
}
|
||||
```
|
||||
|
||||
## 参数定义
|
||||
`inject` 让 Cordis 等待工具注册表就绪。`defineTool` 根据 `parameters` 推导并校验 `args`；`execute` 返回 `output.schema` 声明的规范值，`output.render` 再将该值转换为面向模型的内容。
|
||||
|
||||
`parameters` 用一种简洁的格式描述参数，框架会自动转换为模型需要的 JSON Schema。
|
||||
## 运行并调用工具
|
||||
|
||||
### 基本类型
|
||||
如果开发命令未在运行，请重新启动：
|
||||
|
||||
```ts
|
||||
export const parameters = {
|
||||
path: { type: 'string', required: true },
|
||||
limit: { type: 'integer' },
|
||||
recursive: { type: 'boolean' },
|
||||
parent: { type: 'null' },
|
||||
}
|
||||
// Inferred type: { path: string; limit?: number; recursive?: boolean; parent?: null }
|
||||
```sh
|
||||
pnpm run dsh web --config ./scratch-plugin/cordis.yml
|
||||
```
|
||||
|
||||
### 枚举
|
||||
|
||||
```ts
|
||||
export const parameters = {
|
||||
mode: { type: 'string', required: true, enum: ['read', 'write', 'append'] },
|
||||
}
|
||||
// Inferred type: { mode: 'read' | 'write' | 'append' }
|
||||
```
|
||||
|
||||
### 嵌套对象
|
||||
|
||||
```ts
|
||||
export const parameters = {
|
||||
options: {
|
||||
type: 'object',
|
||||
additionalProperties: true,
|
||||
properties: {
|
||||
timeout: { type: 'number' },
|
||||
retries: { type: 'number' },
|
||||
},
|
||||
},
|
||||
}
|
||||
// The declared fields are inferred; additional JSON-valued keys are allowed.
|
||||
```
|
||||
|
||||
### 数组
|
||||
|
||||
```ts
|
||||
export const parameters = {
|
||||
tags: {
|
||||
type: 'array',
|
||||
items: { type: 'string' },
|
||||
},
|
||||
}
|
||||
// Inferred type: { tags?: string[] }
|
||||
```
|
||||
|
||||
### 每个属性的字段
|
||||
|
||||
| 字段 | 类型 | 说明 |
|
||||
|------|------|------|
|
||||
| `type` | `'string' \| 'number' \| 'integer' \| 'boolean' \| 'null' \| 'object' \| 'array' \| 'json'` | 值类型；`json` 接受任意无损 JSON 值 |
|
||||
| `required` | `true` | 标记为必填（影响类型推导） |
|
||||
| `description` | `string` | 发送给模型的描述 |
|
||||
| `enum` / `const` | 匹配类型的标量值 | 允许的字面量值，在编写和运行时边界校验 |
|
||||
| `properties` | `ParameterSchemaSpec` | 对象的嵌套属性 |
|
||||
| `additionalProperties` | `true \| false` | 每个显式对象节点都必须声明 |
|
||||
| `items` | `ValueSchemaSpec` | 数组的元素 schema |
|
||||
| `oneOf` | 至少两个 `ValueSchemaSpec` 分支 | 要求恰好匹配一个分支；代替 `type` 使用 |
|
||||
|
||||
外层 `parameters` 映射是一个隐式的开放对象。显式嵌套对象需自行选择是否开放；不通过 `defineTool` 注册的原始 JSON Schema 保持 JSON Schema 的默认开放语义。
|
||||
|
||||
## execute 函数
|
||||
|
||||
`execute` 接收经过校验的 `args`（类型自动推导）和一个 `exec` 上下文对象：
|
||||
|
||||
```ts
|
||||
import { defineTool } from '@deepseek-ai/dsh-tools'
|
||||
|
||||
export const tool = defineTool({
|
||||
name: 'example',
|
||||
description: 'Return an example result.',
|
||||
parameters: {},
|
||||
output: {
|
||||
schema: { type: 'string' },
|
||||
render: (_args, value) => [{ type: 'text', text: value }],
|
||||
},
|
||||
async execute(args, exec) {
|
||||
// args: inferred from parameters
|
||||
// exec: ToolExecution context
|
||||
|
||||
// Return the value declared by output.schema.
|
||||
void args
|
||||
void exec
|
||||
return 'result here'
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
### 返回值
|
||||
|
||||
`execute` 返回由 `output.schema` 声明的无损 JSON 值。`output.render(args, value)` 会将经过校验的值另外转换为 Native／模型可见的内容：
|
||||
|
||||
```ts ignore-check
|
||||
output: {
|
||||
schema: {
|
||||
type: 'object',
|
||||
additionalProperties: false,
|
||||
properties: {
|
||||
path: { type: 'string', required: true },
|
||||
content: { type: 'string', required: true },
|
||||
},
|
||||
},
|
||||
render: (_args, value) => [{ type: 'text', text: value.content }],
|
||||
},
|
||||
async execute(args) {
|
||||
return { path: args.path, content: await readFile(args.path, 'utf8') }
|
||||
}
|
||||
```
|
||||
|
||||
执行期间的程序化调用方可以使用规范值，但 `tool/result` 不会持久化该值；渲染后的内容和可选的 `presentationMeta` 才是可回放的投影。工具主体返回的值若不满足 schema 或不是无损 JSON，就会变为 `INVALID_TOOL_OUTPUT` 失败。
|
||||
|
||||
### 参数校验
|
||||
|
||||
`defineTool` 在调用 `execute` 之前会自动校验模型生成的参数。如果参数不合法，会抛出 `ToolArgsError`，框架将其转换为 `isError` 结果返回给模型，让模型自行修正。
|
||||
|
||||
你不需要在 `execute` 里手动校验参数类型。
|
||||
|
||||
## 展示层（Presentation）
|
||||
|
||||
工具可以定义与传输方式无关的展示方法，供终端和 Web 客户端使用：
|
||||
|
||||
```ts ignore-check
|
||||
defineTool({
|
||||
name: 'bash',
|
||||
// ...
|
||||
output: {
|
||||
schema: { type: 'string' },
|
||||
render: (_args, value) => [{ type: 'text', text: value }],
|
||||
},
|
||||
presentCall(args) {
|
||||
return {
|
||||
card: 'terminal',
|
||||
title: args.command,
|
||||
}
|
||||
},
|
||||
presentResult(args, result) {
|
||||
return {
|
||||
card: 'terminal',
|
||||
output: result.content.map(b => b.type === 'text' ? b.text : '').join(''),
|
||||
}
|
||||
},
|
||||
})
|
||||
```
|
||||
|
||||
`presentCall` 和 `presentResult` 是**纯函数**，不能有副作用——UI 可能在流式传输中和会话回放中多次调用它们。
|
||||
|
||||
## 注册与卸载
|
||||
|
||||
`ctx.tools.register()` 返回值就是 disposer。但由于你在 `ctx` 上调用，框架已经自动追踪了这个注册——插件卸载时会自动移除工具。你不需要手动调用 disposer。
|
||||
|
||||
```ts ignore-check
|
||||
// This is sufficient:
|
||||
ctx.tools.register(defineTool({ /* ... */ }))
|
||||
|
||||
// No saved disposer or extra cleanup registration is needed.
|
||||
```
|
||||
|
||||
## 完整示例
|
||||
|
||||
一个文件计数工具：
|
||||
|
||||
```ts
|
||||
import type { Context } from 'cordis'
|
||||
import { defineTool } from '@deepseek-ai/dsh-tools'
|
||||
import { readdir } from 'node:fs/promises'
|
||||
|
||||
export const name = 'file-counter'
|
||||
export const inject = ['tools']
|
||||
|
||||
export function apply(ctx: Context) {
|
||||
ctx.tools.register(defineTool({
|
||||
name: 'count_files',
|
||||
description: 'Count files in a directory.',
|
||||
parameters: {
|
||||
path: { type: 'string', required: true, description: 'Directory path' },
|
||||
extension: { type: 'string', description: 'Filter by extension (e.g. ".ts")' },
|
||||
},
|
||||
output: {
|
||||
schema: {
|
||||
type: 'object',
|
||||
additionalProperties: false,
|
||||
properties: {
|
||||
count: { type: 'integer', required: true },
|
||||
files: { type: 'array', required: true, items: { type: 'string' } },
|
||||
},
|
||||
},
|
||||
render: (_args, value) => [{ type: 'text', text: `Found ${value.count} files.` }],
|
||||
},
|
||||
async execute(args) {
|
||||
const entries = await readdir(args.path, { withFileTypes: true })
|
||||
let files = entries.filter(e => e.isFile())
|
||||
if (args.extension) {
|
||||
files = files.filter(f => f.name.endsWith(args.extension!))
|
||||
}
|
||||
return { count: files.length, files: files.map(file => file.name) }
|
||||
},
|
||||
}))
|
||||
}
|
||||
```
|
||||
打开 `http://127.0.0.1:3080`，然后输入：`Use the greet tool to greet Ada.` 模型可以调用 `greet`，并收到 `Hello, Ada!` 这一工具结果。

When a capability is general enough to need replaceable implementations, such as Bash execution, Harness splits it into three packages: an **interface**, an **implementation**, and a **consumer**. Each layer can evolve or be replaced independently.
