The third-party base class machinesmith can make prototypes, which basically function like spells. The prerequisite for the feat Scribe Scroll is having a caster level of 1. Every single magical thing the machinesmith does counts the creature's machinesmith level as the creature's caster level. In addition, a machinesmith gains bonus item creation feats:
Crafting Expertise (Su): At 3rd level, the machinesmith gains Craft Wondrous Item as a bonus feat. At 8th level he gains Craft Magic Arms and Armor. At 15th level he gains the Craft Construct feat. He uses his machinesmith levels in place of caster level when making such items. In order to add a special ability to an item, he must have access to the prerequisite spells, either through use of a magical item or cast by another spellcaster.
(Emphasis mine.) Does such items mean that the creature's machinesmith levels count as caster levels only and exclusively for creating magic items covered by the feats listed for craft expertise? Or, using this as a guideline, can a machinesmith meet the prerequisite for, for example, the feat Scribe Scroll?
