According to instruction, knits article or object? (5,1,5)

'according to instruction' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'knits article or object?' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'knits' is 'stink' which is within the answer.
'article' could be 'a' (the indefinite article in English) and 'a' is found within the answer.
'object?' could be 'rise' (rise is a kind of object) and 'rise' is found in the remaining letters.
A single letter 'a' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
