(2) The petition shall:

2. (b) contain a specific recital of the facts, observations, and conversations with the inmate that form the basis for the petition.
(3) The petition may be based upon knowledge or information and belief and may be filed by the inmate alleged to be incompetent, legal counsel for the inmate, or by an attorney representing the state.
