Being untidily coiled will do no harm (6)

Ross

I believe the answer is:

docile

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

Here is my best explanation:

'will do no harm' is the definition.
I can't judge whether this definition defines the answer.

'being untidily coiled' is the wordplay.
'coiled' can be anagrammed to 'DOCILE'.
Though, I am not clear how the anagram is indicated.

Can you help me to learn more?
