Synthesis example: a ReplyToolMixin UIWorker adds a start_review tool that fans
out to clarity/tone peers via start_user_job_group, translates each reviewer
response into an add_note command in on_job_response, handles a client
note_click event via @on_ui_event, and keeps history across turns.
A UIWorker with a custom reply tool fans research out to three BaseWorker peers
via start_user_job_group; their progress streams to the client as ui-task cards
and the user can cancel a group mid-flight.
A ReplyToolMixin UIWorker that fills inputs (fills) and toggles checkboxes /
presses submit (click) by voice — the state-changing half of the standard
action set.
A ReplyToolMixin UIWorker that grounds in the user's text selection (the
<selection> block in the snapshot) and points back via select_text — both
directions of deictic reference.
The voice LLM delegates to a ReplyToolMixin UIWorker that scrolls offscreen
items into view and highlights the phones it names — exercising the scroll_to /
highlight UI commands and the [offscreen] state tag.
Smallest UIWorker demo: a voice LLM in the main pipeline delegates
screen-relevant utterances to a UIWorker via a respond job; the UIWorker
auto-injects the current <ui_state> and answers grounded in what's on screen.
Includes a vanilla-JS client that streams accessibility snapshots over RTVI.
