(Note: I was in IT management from 1995-2012, after which I decided to return to being a worker bee.)
"Empowerment" is generally a euphemism for "abdication of management responsibility." And "keep an eye on" implies a type of observation associated with toddlers who might get into trouble.
Stay objective. A general rule for objectivity when reporting on people and their activities is the avoidance of anything for which there is no useful "unit of measure." You can say these things about your colleague:
Comes to work on time.
Is available during the workday.
Sticks to the assigned task (assuming that you understand what it is).
Gets job done (assuming there is a due date).
Follows measurable processes, such as keeping source code committed to the repo, or keeping documents in the approved, secure environment.
You should avoid providing subjective assessments unless you are widely thought to be an expert within the company. Tell the boss that you can only provide facts; their importance and relevance are a matter for management.
