Move the agent-spine bundle and the stdio/ACP/JSON-RPC app packages out of core/ and ui/ into a new packages/examples/ group, renamed with a -demo suffix so the npm name marks them as non-product surface: core/agent-core -> examples/agent-spine-demo (dsh-agent-spine-demo) ui/stdio-agent -> examples/stdio-demo (dsh-stdio-demo) ui/acp-agent -> examples/acp-demo (dsh-acp-demo) ui/jsonrpc-agent -> examples/jsonrpc-demo (dsh-jsonrpc-demo) Update every code/config/test reference and reference-only doc mentions, and regenerate module-graph, config-catalog, and doc-graphs. The jsonrpc bin (dsh-jsonrpc-agent) and single-file exe (dsh-jsonrpc-agent-pkg) keep their names; the SDK runtime-startup surface is reconciled separately.

# User Interaction
|
|
|
|
The user-interaction seam of [dsh-user-interaction](../../packages/ui/user-interaction). It is the provider-neutral vocabulary a tool or permission plugin uses when it needs the human to answer before the agent can continue. UI surfaces provide the active `UserInteractionProvider`: `dsh-stdio-demo` renders questions in readline, and `dsh-acp` maps them to ACP form elicitations.
|
|
|
|

|

|
|
## Question options
|
|
|
|
`AskUserQuestionOption` is the selectable-choice shape. `label` is the user-facing option text and also the model-facing selected value; `description` is optional UI help text.
|
|
|
|
```ts type-equiv
|
|
interface AskUserQuestionOption {
|
|
/** User-facing label. */
|
|
label: string
|
|
/** Optional extra context rendered by capable UIs. */
|
|
description?: string
|
|
}
|
|
```
|
|
|
|
## Question item
|
|
|
|
`AskUserQuestionItem` is one question in a request. The model supplies a stable `id`, which is echoed back with the answer so batched questions remain routable.
|
|
|
|
```ts type-equiv
|
|
interface AskUserQuestionItem {
|
|
/** Stable model-provided question id, echoed in the answer. */
|
|
id: string
|
|
/** The question to display. */
|
|
question: 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
|
|
}
|
|
```
|
|
|
|
## Ask request
|
|
|
|
`AskUserQuestionRequest` is the cross-package request. `questions` is an array so a UI can present related prompts in one flow while preserving a stable id per answer.
|
|
|
|
```ts type-equiv
|
|
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
|
|
}
|
|
```
|
|
|
|
## Answer
|
|
|
|
Providers return one answer per answered question id. `selected` contains selected option labels, and `custom` carries a free-form "Other" answer when the user typed one. When `custom` is present, `selected` is empty; custom text is an answer override, not a supplement to selected choices.
|
|
|
|
```ts type-equiv
|
|
interface AskUserQuestionAnswerItem {
|
|
/** The answered question id. */
|
|
id: string
|
|
/** Selected option labels. Empty when the answer is purely custom text. */
|
|
selected: string[]
|
|
/** Optional free-text "Other" answer. */
|
|
custom?: string
|
|
}
|
|
```
|
|
|
|
```ts type-equiv
|
|
interface AskUserQuestionAnswer {
|
|
/** Structured answers keyed by question id. */
|
|
answers: AskUserQuestionAnswerItem[]
|
|
}
|
|
```
|
|
|
|
## Provider
|
|
|
|
Only one provider may be active in a context. Provider registration is effect-bound so HMR/disposal removes the active UI.
|
|
|
|
```ts type-equiv
|
|
interface UserInteractionProvider {
|
|
ask(request: AskUserQuestionRequest): Promise<AskUserQuestionAnswer>
|
|
}
|
|
```
|
|
|
|
## Errors
|
|
|
|
`UserInteractionError` extends `HarnessError`, so `ctx.tools.execute()` preserves `{ name, code }` for model-facing tool failures such as `EMPTY_QUESTIONS`, `NO_PROVIDER`, `ASK_ABORTED`, or ACP-side cancellation.
|
|
|
|
```ts type-equiv
|
|
class UserInteractionError extends HarnessError {
|
|
constructor(message: string, code: string, options?: ErrorOptions) {
|
|
super(message, code, options)
|
|
this.name = 'UserInteractionError'
|
|
}
|
|
}
|
|
```
