The 'language' used in KR need not be context-dependent or ambiguous. If the blackboard is recognized (by the sensory perception module) as 'black', that would be the best description in KR, because that's the limit of sensory perception. Of course, normally the AGI will have more details of the board such as better color discernment, and that the board has a frame, etc.
I still think the KR language does not need context-dependency or ambiguity. Except ambiguities with respect to the external
world, which always exist.
