connect

Connect to the HenryKnows page the person is watching (its light turns green) and get the session for share_to_page. Only for people who gave you a session code or asked to follow along on a page. Side effects: creates a session, or links the one the person gave, and returns that session and the page's watch link; a new session starts each time it is called without a code; nothing is deleted.

Argument	Type	Description
session	string	The session code the person gave you (from their HenryKnows page). Omit to start a new session and get a new watch link.

Input schema (JSON)

{
  "type": "object",
  "properties": {
    "session": {
      "type": "string",
      "pattern": "^[a-f0-9]{64}$",
      "description": "The session code the person gave you (from their HenryKnows page). Omit to start a new session and get a new watch link."
    }
  },
  "additionalProperties": false
}

search_sources

Search HenryKnows' knowledge base (regulations, SEVP/USCIS guidance, Federal Register rules) and get the matching passages with their source links, so you can read and cite the text yourself. Fast; no model call. Read-only: nothing is stored.

read-only

Argument	Type	Description
limit	integer	How many passages (default 6).

      "type": "string",
      "maxLength": 500,
      "minLength": 2
    }
  },
  "additionalProperties": false
}

share_to_page

Add a question and its HenryKnows answer (or a search and its passages) to the thread on the HenryKnows page the person connected, so they can see it there with its sources. Only for people who connected a page. Side effects: appends one entry to that page's thread, kept 24 hours; nothing else changes.

Argument	Type	Description
answer	string	HenryKnows' answer text (omit for a search).
session*	string	The session returned by connect (or the session code the person gave you).
sources	array	The sources HenryKnows returned, as given.
audience	string
