How an agent uses it

  • Resolve

    The agent passes the nameplate reference. resolve_equipment says whether the unit is covered.

  • Ask

    answer_hvac_question returns a short answer with one source_id per claim.

  • Show the page

    get_hvac_document_page returns the cited page as an image so the tech can check it.

Tool parameters and errors are in the API docs.

What comes back

A claim and the passage it rests on. The agent can show both to the technician.
