AskUserQuestionItem.detail is part of the user-interaction seam contract but the web frame schema dropped it and the composer never rendered it (review r3635427108). askUserQuestionItemSchema now forwards detail, the composer renders it under the title in the description text style, and the fixture's multi-select question carries one.
@deepseek-ai/dsh-client-ui-question
Web ask_user_question feature plugin. Its host half mounts dsh-tool-ask-user only when the Web feature is selected; its browser half registers the question entry in the conversation-owned conversation.composer keyed slot.
The component renders one question at a time with progress navigation, single- and multi-select choices, recommendation badges derived from label suffixes, and custom answers. Single-select choices advance immediately, and Enter submits once every question is answered or skipped; Enter during IME composition confirms the input candidate without advancing. It submits one structured answer batch for the whole request: “Skip this question” retains other drafts and emits the existing blank { selected: [] } shape for that item, while close rejects the whole wait as ASK_CANCELLED.
Selection state is local to a component keyed by the request rpcId. A replay with the same id preserves a still-mounted draft, while question/resolved from the host removes the composer. The host remains authoritative: successful HTTP delivery does not remove pending state locally.
Model Experience
Indirectly, through dsh-tool-ask-user; that package owns the model-visible tool schema and structured result.
KV Cache effect
No direct invalidation; dsh-tool-ask-user owns the model-visible tool call and result.
Known Limitations and Deferred Work
- Unsubmitted drafts are not durable — reconnect resync or a full page reload restores the host-owned pending request with the same rpcId, but a composer unmount resets local option and custom-text drafts.
- One request owns the composer at a time — later pending requests remain in the session snapshot and become visible after the earlier request resolves.
