Apparently something subtle is happening here.
It seems to me that when people say "believe", they mean "hold true" or "consider to be true".
Therefore, I parse the statement as equivalent to "...criterion for what to hold true should be what is true..."
I suppose I should have said that the statement is circular, rather than tautological since the verbs are different.

If someone states "A=A", then there is absolutely no information content, and thus nothing in the statement itself with which to agree or disagree. I can certainly agree with the validity of the form within symbolic logic, but that's a different (larger) context.
Similarly, I was not agreeing or disagreeing with the meaning of Stahis' statement, but rather the form which seems to me to contain a piece of circular reasoning, implying perhaps that the structure of the thought was incoherent within a larger context.

Yes, I favor a pragmatic approach to "belief", but I distinguish my thinking from that of (capital P) Pragmatists in that I see knowledge (and the knower) as firmly grounded in a "reality" that can never be fully known but can be approached via an "evolutionary" process of growth tending toward an increasingly effective model of what works within an expanding scope of interaction within a reality that appears to be effectively open-ended in its potential complexity. Whereas many Pragmatists see "progress" as fundamentally illusory, I see progress, or growth, as essential to an effective world-view for any intentional agent.

I agree with much of your thinking, but I take exception to exceptions (!) such as the ones you mentioned above.
All meaning is necessarily within context.
The existence of prime numbers is not an exception, but the context is so broad that we tend to think of prime numbers as (almost) fundamentally real, similarly to the existence of gravity, another very deep regularity of our interactions with "reality".
The statement "I am conscious", as usually intended to mean that one can be absolutely certain of one's subjective experience, is not an exception, because it's not even coherent. It has no objective context at all. It mistakenly assumes the existence of an observer somehow in the privileged position of being able to observe itself. Further, there's a great deal of empirical evidence showing that the subjective experience that people report is full of distortions, gaps, fabrications, and confabulations.
If instead you mean that you know you are conscious in the same sense that you know other people are conscious, then that is not an exception, but just a reasonable inference, meaningful within quite a large context.
If Descartes had said, rather than "Je pense, donc je suis", something like "I think, therefore *something* exists", then I would agree with him. Cartesian dualism has left western philosophy with a large quagmire into which thinking on consciousness, personal identity, free-will and morality easily and repeatedly get stuck in paradox.
Paradox is always a case of insufficient context. In the bigger picture all the pieces must fit.
