Maybe brief jibe spin doctor spun (3,11)

I believe the answer is:

job description

I'm a little stuck... Click here to teach me more about this clue!

'maybe brief' is the definition.
The definition suggests a singular noun which matches the answer.

'jibe spin doctor spun' is the wordplay.
'spun' indicates an anagram.
'jibe'+'spin'+'doctor'='jibespindoctor'
'jibespindoctor' is an anagram of 'JOB DESCRIPTION'.

Can you help me to learn more?

(Other definitions for job description that I've seen before include "duties assigned" , "18 [PATIENT]" , "Outline of tasks" , "Details of position" .)

I've seen this clue in The Times.
