The RAW includes the phrase "within the limits of its abilities" as well as "to the exclusion of all other activities except those necessary for day-to-day survival (such as sleeping, eating, and so forth)."For me, the fact that "to the best of its abilities" is absent, signifies a material omission to the manner in which the spell is intended to work. Like anything, a DM can always Rule 0 that requirement in there, but RAW doesn't have it.
Interpreting those phrases in such a way that they don't imply "to the best of its abilities" is...uniquely Arrowhawkian.
