/**
|
|
* Human-in-the-loop demo tools.
|
|
*
|
|
* HITL here is a **blocking frontend tool**: `confirm_write`'s handler calls
|
|
* `await thread.awaitChoice(<ConfirmAction/>)`, which posts the approval card and
|
|
* blocks until the user clicks (resolving to `{confirmed}`). The agent is
|
|
* instructed (system prompt in `app/index.tsx`) to call `confirm_write` BEFORE
|
|
* `send_announcement`, so a consequential action is always gated on a human.
