Commits an error in writing the clue for “odes” (4,5)

'commits' is the definition.
The definition and answer can be both to do with social activities as well as being verbs in their -s form.
Maybe you can see a link between them that I can't see?

'an error in writing the clue for odes' is the wordplay.
I cannot quite understand how this works, but
'writing' could be 'r' (I've seen this in other clues) and 'r' is found in the answer.
an anagram of 'odes' is 'does' which is located in the answer.
This explanation may well be incorrect...

Can you help me to learn more?
