All definitions should be circular. "The president is the Head of State" is a correct definition. "The president is Obama" is true, but not a definition.

Non-circular definitions can certainly be perfectly fine:

"A bachelor is an unmarried man.'

This style is used in math to define new concepts to simplify communication and thought.

"A bachelor is an unmarried man.'

If that is non circular, so is [the statement that, if believed by a rational agent, would cause it to do X]

I'm quite confused. By circular do you mean anaylitcal, or recursive? (example of the latter: a setis something that can contain elemetns or other sets)

I don't think your statement was self referential or problematic,.
