gdrive.getDocument
     Description: Retrieves a document from Google Drive
     Parameters:
                documentId (required, string): The ID of the document to retrieve
                fields (optional, string): Specific fields to return
     Returns: Document object with title, body content, metadata, permissions, etc.

salesforce.updateRecord
    Description: Updates a record in Salesforce
    Parameters:
               objectType (required, string): Type of Salesforce object (Lead, Contact, Account, etc.)
               recordId (required, string): The ID of the record to update
               data (required, object): Fields to update with their new values
     Returns: Updated record object with confirmation

TOOL CALL: gdrive.getDocument(documentId: "abc123")
        → returns "Discussed Q4 goals...\n[full transcript text]"
           (loaded into model context)

TOOL CALL: salesforce.updateRecord(
			objectType: "SalesMeeting",
			recordId: "00Q5f000001abcXYZ",
  			data: { "Notes": "Discussed Q4 goals...\n[full transcript text written out]" }
		)
		(model needs to write entire transcript into context again)
