check_message_status
Whether the confirmation email for a `send_message` submission was delivered: `queued` / `sent` / `failed` (+ reason) / `unknown`. Never whether the link was clicked.
AON — Agent Offer Network Tools (5)
aon_search_offers
Search offers by natural-language intent. Arguments are an [AgentOffer Query](https://github.com/agentoffernetwork/protocol) request object — the same shape as the REST API. Returns offers with pricing, a tracking link each, and an `engagement` block of pre-validated follow-up suggestions the agent…
aon_resolve_category
Turn free text ("hiking boots", "team chat software") into AON Taxonomy v1 category ids — the model never has to memorize or invent them.
aon_get_category_schema
Optional Hosted extension: return decision factors for an already resolved category id, to ask the right clarifying question before searching. Its standalone result does not add `decision_factors` to the Query request or response.
aon_submit_feedback
Record an explicit "dismissed" / "not interested" from the user on an offer — never inferred from silence. *Early scaffold: the call is acknowledged with success, but feedback is not persisted yet; the workflow behind it is rolling out.*
aon_manage_watch
Restore (`watch`) or cancel (`unwatch`) the default watch on an offer or category when the user explicitly asks. *Early scaffold: acknowledged with success, watch state not persisted yet.*
