I intend to do MANY recursive operations to match quit a few GDBs and I need to run it that way instead of spending the day doing them one at a time? Is there a library that has the Python/ArcGIS code behind the toolbox folder?
The actual code is not available, but you can access existing tools using arcpy. For example look at the code snippet for Clip—Help | ArcGIS for Desktop
and here is the help for arcpy
What is ArcPy?—Help | ArcGIS for Desktop and if you intend to work in Pro ArcGIS Pro ArcPy Reference—ArcGIS Pro | ArcGIS for Desktop
