Poor colt somehow to produce good form (8)
I believe the answer is:
protocol
'good form' is the definition.
(I've seen this before)
'poor colt somehow' is the wordplay.
'somehow' indicates anagramming the letters.
'poor'+'colt'='poorcolt'
'poorcolt' with letters rearranged gives 'PROTOCOL'.
'to produce' is the link.
(Other definitions for protocol that I've seen before include "Official code of conduct for a group" , "official rules" , "Poor clot involved in kind of status etiquette" , "Etiquette with regard to rank or status" , "customs" .)
