Barely adequate coverage of some agreement (6)

I believe the answer is:

meagre

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

'barely adequate coverage of some agreement' is the definition.
I can't judge whether this definition defines the answer.

'of some agreement' is the wordplay.
'of' indicates a hidden word.
'MEAGRE' is hidden within 'some agreement'.

Can you help me to learn more?

(Other definitions for meagre that I've seen before include "Scanty, skimpy" , "Stingy - thin" , "skinny" , "Thin or scanty" , "Slight" .)

I've seen this clue in the Sydney Morning Herald.
