Hook integration scripts v. 86 supports Keep It by Reinvented Software

Got it. Thanks.

Now that Hook can obtain both name and address with a single script which returns a [name](url) pattern like:

tell application id "com.reinvented.KeepIt"
    set xs to selected items as list
    if {} ≠ xs then
        tell item 1 of xs
            if missing value is not it then
                "[" & name & "](keepit://link?item=" & id & ")"
            end if
        end tell
    end if
end tell

I am interested to see that your supplied solutions still use two separate scripts – is there a particular reason for doing it that way ?
