Tex. Code Crim. Proc. art. 51.05
When the accused is brought before the magistrate, he shall hear proof, and if satisfied that the accused is charged in another State with the offense named in the complaint, he shall require of him bail with sufficient security, in such amount as the magistrate deems reasonable, to appear before such magistrate at a specified time. In default of such bail, he may commit the defendant to jail to await a requisition from the Governor of the State from which he fled. A properly certified transcript of an indictment against the accused is sufficient to show that he is charged with the crime alleged. One arrested under the provisions of this title shall not be committed or held to bail for a longer time than ninety days.
