用户交互
English | 中文
dsh-user-interaction 的用户交互 seam。它是工具或权限插件需要人类回答后 agent(智能体)才能继续时所使用的、提供方无关的词汇。UI surface 提供活跃的 UserInteractionProvider;dsh-tui 使用键盘驱动的 overlay,host 运行时把请求转发给它连接的客户端。
源码:packages/ui/user-interaction/src/index.ts
问题选项
AskUserQuestionOption 是可选择项的形状。label 是面向用户的选项文字,同时也是面向模型的选中值;description 是可选的 UI 帮助文本。
/** One selectable answer offered to the user. */
interface AskUserQuestionOption {
/** User-facing label. */
label: string
/** Optional extra context rendered by capable UIs. */
description?: string
}
问题条目
AskUserQuestionItem 是请求中的一个问题。调用方提供稳定的 id,它会随答案原样返回,使批量问题仍可路由。可选的 detail 携带辅助文本;提供方会将其随问题渲染,但不会放入可选 option label。
/** One question in a user-interaction request. */
interface AskUserQuestionItem {
/** Stable caller-provided question id, echoed in the answer. */
id: string
/** The question to display. */
question: string
/** Optional supporting detail rendered with the question but kept out of option labels. */
detail?: string
/** Optional short heading/group label. */
header?: string
/** Optional choices the UI can render as a menu. */
options?: AskUserQuestionOption[]
/** Whether more than one option may be selected. Defaults to single-select. */
multiSelect?: boolean
}
提问请求
AskUserQuestionRequest 是跨包(package)的请求。questions 是数组,这样 UI 可以在一个流程中呈现相关提示,同时保持每个回答有稳定的 id。
/** Request for a human answer. */
interface AskUserQuestionRequest {
/** Questions to display. */
questions: AskUserQuestionItem[]
/** Calling agent, when the request came from an agent tool call. */
agent?: Agent
/** Abort signal for the owning tool/step. */
signal?: AbortSignal
}
回答
提供方为每个问题 id 返回一个回答项。selected 包含选中的选项标签,custom 在用户输入自由文本时携带「其他」回答。当 custom 存在时,selected 为空;自定义文本是对选中项的覆盖,而非补充。UI 也可以使用 selected 为空且不含 custom 的回答项,在其余问题均已完成的批次中保留被跳过的问题。
/** Answer to one question. */
interface AskUserQuestionAnswerItem {
/** The answered question id. */
id: string
/** Selected option labels. Empty for custom or unanswered choices. */
selected: string[]
/** Optional free-text "Other" answer. */
custom?: string
}
/** The human's answer. */
interface AskUserQuestionAnswer {
/** Structured answers keyed by question id. */
answers: AskUserQuestionAnswerItem[]
}
提供方
同一上下文中只能有一个活跃的提供方。提供方注册绑定到 effect,因此 HMR(热模块替换)或 dispose(资源释放)会移除当前活跃的 UI。
/** UI-side provider for user questions. */
interface UserInteractionProvider {
ask(request: AskUserQuestionRequest): Promise<AskUserQuestionAnswer>
}
错误
UserInteractionError 继承 HarnessError,因此 ctx.tools.execute() 会保留 { name, code },用于面向模型的工具失败,如 EMPTY_QUESTIONS、NO_PROVIDER、ASK_ABORTED 或 UI 侧取消。
/** Stable error taxonomy for user-interaction failures. */
class UserInteractionError extends HarnessError {
constructor(message: string, code: string, options?: ErrorOptions) {
super(message, code, options)
this.name = 'UserInteractionError'
}
}
