DIY cult worried about current clarity (8)
I believe the answer is:
lucidity
'clarity' is the definition.
(I know that clarity can be written as lucidity)
'diy cult worried about current' is the wordplay.
'worried' indicates anagramming the letters (worry can mean to interfere with or disturb).
'about' indicates putting letters inside.
'current' becomes 'I' (symbol for electric current).
'diy'+'cult'='diycult'
'diycult' anagrammed gives 'lucdity'.
'lucdity' placed around 'i' is 'LUCIDITY'.
(Other definitions for lucidity that I've seen before include "Brilliance - explicitness" , "Clarity (of thought)" , "Clarity of expression" , "Clearness" .)
