Read-only; uses no AI quota. Each result has `insert`, the exact markup to put in the reply. To show a help article to the visitor, write `[label](hal-article:<article id or slug>)` into the `content` of reply_to_conversation. The widget renders it as a clickable card at that spot, on its own line (it is not an inline link inside a sentence), so put it between sentences or paragraphs, e.g. "Refunds take 5 days.\n[Refund policy](hal-article:refund-policy)\nAnything else?". The label is the card title, so use the article title. Several cards in one reply are fine. Only published articles the visitor may see are accepted; each reference is checked and rewritten to the slug for the visitor's language.

To walk the visitor through a flow, pass `offer_guide_id` instead of writing guide markup. To send files, pass `attachments`; they are delivered with the message in the widget and in email replies.	Send an agent message to a conversation. To show a help article to the visitor, write `[label](hal-article:<article id or slug>)` into the `content` of reply_to_conversation. The widget renders it as a clickable card at that spot, on its own line (it is not an inline link inside a sentence), so put it between sentences or paragraphs, e.g. "Refunds take 5 days.\n[Refund policy](hal-article:refund-policy)\nAnything else?". The label is the card title, so use the article title. Several cards in one reply are fine. Only published articles the visitor may see are accepted; each reference is checked and rewritten to the slug for the visitor's language.

`reset_email_deliverability_health`Start a fresh 30-day health window for a project that is blocked from sending broadcasts by old bounces or complaints. ONLY use this after the bounced and complained addresses have been suppressed (list_email_suppressions / suppress_email_recipient) so the same list cannot bounce again. HAL enforces this: the reset is refused, and nothing changes, if any recipient that bounced or complained in the current window is not suppressed (by a project-wide or platform-wide suppression), and a project can be reset at most once per 30 days. Once it succeeds, sends before the reset stop counting toward the project's bounce and complaint rate, and any new bounces after it count normally and can block the project again. This only resets HAL's own project health window; it does not change the Amazon SES account reputation or review status. Per-broadcast auto-pause is not affected. Cannot be undone and is logged: get explicit user confirmation, then pass confirm: true and a reason describing the cleanup (3-500 characters). Returns the updated health (including reset_at).

`resume_broadcast`Resume a paused broadcast. Broadcasts auto-pause when their bounce or spam-complaint rate is too high, or when a scheduled send hits a blocking deliverability check; `pause_reason` says why. Only resume after the user understands the reason and has addressed it (e.g. removed bad addresses). The remaining recipients are sent to, and it pauses again if rates stay high.

`send_broadcast_now`IMMEDIATELY sends this broadcast to its whole live audience - a real, irreversible email blast to real contacts, not a test. You MUST call preview_broadcast_audience first and pass its exact `count` as confirm_recipient_count; a mismatch is refused. Call get_broadcast_readiness first too: sends with blocking deliverability checks are refused. Only call this after the user has explicitly confirmed they want to send to that many recipients right now.

`set_typing`Show the visitor and your teammates in the dashboard that a reply is being written.
