imccyu ec601ca13d build(vendor): rescope the vendored Cordis packages into @deepseek-ai
Machine-produced by `pnpm run rescope-vendor --apply` plus the regeneration it
prints: `pnpm install` for the lockfile, `pnpm run gen-third-party-notices`,
`verify-translation-pairing --write` for the touched bilingual pairs,
`gen-doc-graphs`, and one typert snapshot whose ids embed character offsets.
`pnpm run rescope-vendor --check` verifies the result.

Renames nine vendored packages (cordis, cosmokit, schemastery and the six
@cordisjs plugins) and every reference that resolves them: manifest names and
dependency keys, module specifiers including declare-module merges, cordis.yml
plugin names, tsconfig paths, every Markdown fence, and `docs/` prose.
Directory names, upstream versions, and dependency ranges are unchanged, so
vendor/README.md still reads as an upstream snapshot; its manifest table gains
an upstream-name column so THIRD_PARTY_NOTICES keeps MIT attribution pointed
at each fork's origin.

The tutorial tier follows the rename end to end: its yaml fences named plugins
the Loader can no longer resolve, its `ts ignore-check` fences disagreed with
the compiled fences beside them, and its prose quoted both. The contracts that
told readers to keep upstream names — the root convention and the vendoring
cookbook's tree comment and manifest invariant — now say to rescope instead.

Two rules read `@deepseek-ai/` as "another workspace plugin": the client bundle
purity gate now names the vendored libraries a browser bundle inlines, and the
files where a bare `cordis` is an agent-preset id keep that product data.

开发一个工具

English | 中文

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。

创建工具插件

scratch-plugin/src/my-plugin.ts 替换为:

import type { Context } from '@deepseek-ai/cordis'
import { defineTool } from '@deepseek-ai/dsh-tools'

export const name = 'greet-tool'
export const inject = ['tools']

export function apply(ctx: Context) {
  ctx.tools.register(defineTool({
    name: 'greet',
    description: 'Greet someone by name.',
    parameters: {
      name: { type: 'string', required: true, description: 'The name to greet' },
    },
    output: {
      schema: { type: 'string' },
      render: (_args, value) => [{ type: 'text', text: value }],
    },
    async execute(args) {
      return `Hello, ${args.name}!`
    },
  }))
}

inject 让 Cordis 等待工具注册表就绪。defineTool 根据 parameters 推导并校验 argsexecute 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。

运行并调用工具

如果开发命令未在运行,请重新启动:

pnpm run dsh web --patch ./scratch-plugin/cordis.yml

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。

下一步

  • 插件配置 — 让问候语可配置。
  • 工具编写参考 — 查阅嵌套 schema、规范值、后台工作、策略钩子、Code Mode 和 UI 卡片。
  • 能力分层 — 将可替换能力拆分为 Service Definition、Service provider 和 Consumer 包。
